Test bed : WLC makes slow WLAN speed vs. Autonomous

Hi experts,
User complint very slow download speed (~140kbps) compare to wire around ~50mbps. Those are too different.
So I move out from the production, then did my own test.
I tested on seperated environment, seperated AP(1130)/switch/ WLC(7.0)/PC client with Windows file sharing. Then compare againt STANDALONE AP. All are flat configure without any Auth etc.
Result are, standalone AP is winner = 5MB/sec while WLC based is only 1MB/sec. Then I also try to do LOCAL SWITCHING (H REAP) to diable tunneling that could make some delay. Result is the same, no improvement.
I also find out for cisco support forum. Much many discussions ask us to disable feature such Client exclude, MFP, Aironet IE and tune for a/b/g supported.
What else to tune or aware of ?
Please do me a suggestion. Thank you.
Nipat.p

David,
Do you mean Static&Dynamic CH? I used default WLC's setting (Dynamic, DCA)?
Anyway, my testbed is using only 1 AP in 2 scenarios WLC-based vs. Autonomous at the same location.
I also asked from the others end user who is using WLC. Windows file share speed is also around 1-2.4MB/sec. So poor!!!
Then, What else for WLC parameter should I take care of? I got a slot to re-test by tomorow.

Satellite A200: Slow WLAN speed with Atheros AR5007EG

Hi there,
I recently bought an Satellite A200 with an Atheros 5007eg wireless lan adapter. I am using Vista. And i'm using a d-link router.
My problem is the following:
Somehow, when I download it only produces 1/4th of the speed I get when i connect it directly to my modem... Ive tried downloading new drivers, but no help there.
Can someone help me pls? I already talked to toshiba NL, they told me to send it to them, they had it for three weeks and then sent it back without doing anything.

As far as I know an BIOS and the Atheros driver update should clear this issue.
A friend of mine has the same notebook and he has updated the both mentioned thing and it works great.
The BIOS update you will find on the Toshiba European driver page and the Atheros WLan driver here:

Download speeds are very slow but speed test is fi...

Hi, I did a speed test which returned a result of 36mb down and 8mb up so didn't really expect a slow download. I started a download on the iplayer which normally downloads at 28-30mb per second but it didn't get above 4mb which is not good.
Anyone experiencing slow download speeds?

Speeds have gone back up to 21mb on the iplayer. Much better but still slower than usual.
When you get used to the fast speeds of Infinity, anything slower is immediately frustrating. Like having to go back to using my Pentium 75Mhz with windows 95.......horror

WLAN Speed Difference

Good morning,
I am noticing a difference in speed when I connect to one WLAN SSID vs another. I have checked the WLC with no noticable difference in the configuration of one over the other. When I do a Speedtest to the same server I get 20Mbps on the slow WLAN and over 150Mbps on the other.
Does anyone have any ideas what could cause this? Could there be a bug in the controller software?
Model 5508 Running :7.4.110.0

“Wireless clients are experiencing very slow speed” ,   is a common problem on a wireless lan environment.
As part of troubleshooting this, we got to take care of
1)      Low Signal Strength.
2)      Low SNR.
3)      Insufficient Data rate.
4)      Packet Drop.
5)      Interference.
6)      Client Driver problem.
7)      QoS related problem.
8)      Problem with Roaming.
9)      OR Any configuration related problem.
During the course of troubleshooting, we do need a way to test the throughput, as and when we make any changes.
IPERF comes as a very handy tool. This can easily tell us the speed of data transfer.
Here are the details for the IPERF test.

Hi,
I have had bt broadband opt3 for almost 3 months now and have always had a healthy 9mb+ connection, however have noticed it being very slow in the evening when I come home from work, I checked the speed last nite as iplayer was constantly freezing and was getting 1mb . A bit upset by this as I got bt broadband to play my ps3 online and to get faster speeds on my laptop, and I use these services mostly at nite.
I checked my speed this morning and was getting 11mb, is this normal or am I being capped I cant believe Id be going over my download limit. Can someone from bt get back to me on this?
Thanks
John

Yes Alison, I think I can see that now. I wouldnt mind if broadband was a bit slower at peak times, I know thats normal, but when I'm only getting 1mb when my max is 14mb, I just dont feel I'm getting what I pay for. And when it gets to the point where I cant watch iplayer without it stuttering everywhere and online games lagging on the ps3, this is certainly not what I'm paying for.
I was hoping one of the mods here would help me and check my line and see if there is any cap on the line and get it removed.
I really dont wanna phone India, I deal with them 5 days a week as is...
Think I will just send one of the mods an email to check my line and see if it is being capped or if somethings wrong.

You will never get decent speeds on Iplayer,
BT limit it because they want you to subscribe to their precious BT Vision service.
The only way you are guaranteed to get decent speeds on BT is to subscibe to BT Vision and also unlimited broadband.
Then you will get priority when you stream TV at your exchange unlike fighting it out with all the other broadband users as you currently are for the available bandwith.the more over subscribed your local exchange the worse it is

Hi John,
I can take a look at the network side of things for you, to see if there is anything I can do to help improve your speed during peak periods. Please could you drop me an email with your BT account details? Please also include a link to this thread. It would also be very helpful if you could run a few speed tests using www.speedtester.bt.com when you feel your Broadband is running slow. I can then check those results from here.
Thanks
Paddy

Well John i'll tell you what it is...
First of all welcome to BT and I hope you'll enjoy 18months of pain and suffer.
OK here it goes....
If you look at your contract, find a rule that says Fair Usage Policy.
Basically it states that BT will cap anyone that is abusing their lines.
However, it does not say what are the limits after which you are going to be capped for how long and at what times. (I'll come back to this later and explain)
If you ring 08007076044 I'm sure that someone will confirm my theory. As constant 1MBit between 6PM till 11/12 PM is actually FUP applied on to your account.
Ok time to explain my frustration about FUP.
Since I signed my contract with "lovely" BT for constant 4 months I had similar issue but it took me even longer to find out what is going on and how to deal with this problem (thanks to google).
FUP team states that if you exceed 100GB in a month (everyone will admit that these days 100GB is nothing when a single game for PS3/XBox360/PC sometimes is more than 5GB and 1080p film is about 12GB) will cap you for a month at peak times to outstanding and superfast 1Mbit (about 130-150KB/s).
I'be been watching my download and for few months never exceeded that 100GB in a month. Been ringing FUP team to verify when suddenly they told me that from (cant remember exactly) March FUP will apply only to accounts that are using Torrents and other P2P.
you won't believe how happy I was hearing that.... So i've started to download and next month guess what.... 1Mbit connection.
Really mad rang FUP team and asked them what on earth is going on. They confirmed that its only P2P and I've explained them that I only use Youtube, BBC iPlayer, Rapidshare, Steam and XBox Live, Beatport (just don't understand how ppl can use torrents and other P2P as they are just way to slow). So they were happy to take the cap off my broadband connection.
Next month same issue solved exactly the same way.
After that for consecutive few months I had no problem whatsoever until September where FUP Team said that there is no such thing and FUP applies to everyone.
So just want to say that BT is rubbish that can't keep their word.
I went to one of the sales advisor in the shopping centre and asked him how FUP works as it does not say in the contract "how, when, who and what".
So he said that policy is applied based on amount of files downloaded within that 100GB. So if I download e.g. 3x 50GB (although its 150GB altogether) files I wont be affected but 100x 1GB will put a cap on me.
I've been so curious if what he said was right and started to download 2x 60GB and guess what... Got frigging FUP placed on my account!!!.
I've got 2months left with them and will be extremely happy to cancel my contract, moreover, I will do everything in my power to sue them under EU Consumer Rights Law (that states that contract should be clear and fair to both sides) as Fair Usage Policy is one of those things that allows BT to do anything they want to their customers;
1. No clear explanation of what FUP is.
2. Does not states the amount of downloaded data required to have cap on the acount
3. Does not states for how long it will be applied
4. Does not states when it will be applied
If you look at e.g. Virgin Broadband everything is clearly written in nice and understandable way. It warns you at what times FUP will be applied under what circumstances and for how long. Isn't it what we all want to know??

@Mateusz I think I maybe a victim of this outragous stint BT have done. I have 2 XBOX 360's running on XBOX Live, 2 Desktop PCs connected to the web constantly, and 3 laptops, we have a torrent sharing running and World Of Warcraft on one of the PCs. All of this is shared across a 6 person family. How can a family where two members goto to college and university do their college ork, download application such as VB.net do their coursework and revise without the hassle of a **** connection. Seriously BT get your ******* head outta your **** and stop this ********, we are customers, we pay for what we are offered. When I signed up several years ago I could download everything on the net woithout infracions on my line being set in motion. You altered my contract without telling me. You will lose custom from this. Also you have ****** my wireless

You lot are lucky, We wish we could be capped to 1mbit. Our IP profile is capped to 500kbit because BT say the line isn't good enough for anything more. We are paying for option3 up to 8mbit and BT have said we must continue to pay for it for the remainder of the contract, or buy ourselves out of it early, the reason they give.... Up to 8mbit means up to 8mbit. If you dont get 8mbit then TOUGH LUCK SUCKERS!!
The outcome? We feel like we've been turned over by a dodgey second hand car salesman called BT. The internet deal he flogged us was a dog, a ringer, it wasn't cosher and certainly had a false MOT certificate.

Hi Amanda,
Why have you joined BT Option 3 when you can not get what BT can offer?
No pun intended but you are a bit of a sucker for paying high prices where other suppliers are cheaper and can provide what your line can support.

we moved house last october to this one, the connection was rubbish from the get-go, BT said the router was broken and we needed a new one, we said OK. That "OK" meant that we had entered into a new contract for option 3 same as out old one. The router wasn't broken, the new one didnt fix or improve the problem, we have since asked for a price reduction or compensation and been told "no". we are in contract and can pay to buy ourselves out of it if we like but otherwise we have to pay for option 3 and recieve fixed rate 500kb.

Hi Amanda,
I think you'll find that the Hold To Term rules have changed. BT are now unable to charge you for the account if you no longer require it. It is against OFCOM's rulings for a company to make more money out of you as a leaving customer than an existing one. However, You will need to pay for the connection charge (if that has not expired it's original differed contract) which is £40. A cancellation fee of £25 if you are simply cancelling and not migrating using a MAC key and for any hardware. The Routers are advertised at £88 and i would suggest that if they believed on to be faulty then that would be replaced under guarantee and not be put on a differed basis. I would check exactly what they say the are charging you and query this through OFCOM. http://www.ofcom.org.uk/

Months of impecable service form BT as an option 3 customer. (I've even recommended BT to people)
but
For the past 2 weeks peak traffic has murdered my connection.
I can get 14mbit off peak, and it used to drop to about 7-9 at peak times.
Now its down to 1-2mbit at peak times. (no i haven't breached FUP as I check my btinternet inbox for the 80GB warning)
I think its resonable to experience drop off but 90%!!!
BT advertising says fast speeds at peak times. less than 2mbit is not fast. (that the governments minimum standard!!!)
I don't know how to procede because when I'm experiencing these issues if I ring up I will end up waiting so long to speak to someone (because its peak time) the concection wiill be better again.
I can think of no recourse other than to approach trading standards...
Guarnetee me 5mbit at peak times (enough to stream HD iplayer) and I'd be happy
That is what BT vision customers are in essence are getting + what ever their PC is using.
Fair usage? what about Fair Supply.

External firewire hard drive reverts to slower transfer speeds

This is the strangest hardware problem I've come across. I'm running a unibody mbp (June 2009) with an external WD 2.0TB Caviar Green drive mounted in a firewire 800 enclosure made by icydock.
Lately, I've noticed that after an unknown amount of uptime, the speed of file transfers to the WD external drive slows down dramatically. I figured this out by watching my time machine transfers take a bit longer after awhile, and I verified this using aja system test and speedutilities.
When I boot my mbp in the morning, file transfers and time machine backups to the external WD transfer at a rate of about 67-75MB/s. This is the speed the drive should always be working at since it's connected via firewire 800. Aja speedtest verifies the speed is as it should be as well.
Then, after a couple hours of using my mbp, or even later in the day, I'll transfer a file to the external WD or run a time machine backup and find that the transfer will only run at a max of 29-35MB/s. This is exactly half the speed the transfer should be going at. Subsequent transfers stay at this slower rate no matter what I do.
However, I've been able to fix this problem by unmounting and remounting the external WD or restarting my mbp. After doing either of these actions, the WD external goes back to contant transfers at 75-80Mbs. So something is happening where the longer the mbp is running, or after some sort of disk activity, the external WD reverts to a slower transfer speed (closer to FW400). I can't isolate whether it's an issue on the mac os side or the hard drive or the hard drive enclosure because I can make the hard drive go back to optimal speed again merely by unmounting and remounting it. This works consistently until a few hours later when the drive begins to handle transfers at half speed again.
I run hourly time machine backups to the drive. The time machine backups can't be the culprit because the drive remains running at optimal speed after the backups (verified with aja system test and speed utilities)
Any possible ideas as to why the drive cuts down to half its optimal transfer rate after a bit of time? I can't figure out the cause of this, and the consistency of the drop leads me to think this is an issue with the power management on the drive since it reverts to full fw800 speed when I umount and remount the drive or restart my computer. Could this be an OSX issue where for some reason the system isn't negotiating the fastest speed?
Any help appreciated.

[SOLVED] Slow read speeds from a DroboFS mounted in fstab via cifs

I've decided to move all my media over to my drobofs which I have and I've mounted the share on the drobo in fstab this way:
//mydrobofs/Media /media/drobofs cifs iocharset=utf8,uid=af,gid=users,guest,dir_mode=0775 0 0
The share is mounted fine at boot but my issue is now the read speeds are very slow. opening a video file with vlc takes 30 seconds or more before it starts playing. Before this was accessing the share on my drobofs via the network tab (samba shares) in Dolphin (using KDE4) and here the video files played immediately in vlc (no delay). The reason why I want to mount the share via cifs and fstab is to move music collection over to the my drobofs and since I'm using Amarok for managing my collection this is the only way to make Amarok see my Music collection on the Drobofs.
Why am I getting so slow read speeds with cifs?
Last edited by fettouhi (2012-05-07 05:54:00)

I did some more testing and seems like the problem has something to do with how many video files there are in the directory. I have some directories with several 100 video files and here I get this long delay but if I play a file that is in a directory by itself or only a few other video files are there, then the video starts immediately (almost). Is there a way to turn off this behaviour in vlc? Is it generating a playlist or what?

Very slow broadband speed following line fault

Having recently had a noisy line fault repaired I have been left with broadband that is running at a very slow speed. Having read several other posts on this forum it seems that my IP profile needs resetting in the local exchange. I am reluctant to try to explain my problem to someone in India (because I can envisage a rather lengthy call which could possibly be to no avail) so can anybody tell me if there is an alternative way to reset my IP profile.
BT's speed test results were as follows:
Download speed: 680Kbs
DSL connection rate: 2464Kbs (downstream) 448Kbs (upstream)
IP Profile: 750Kbs
Any help would be useful,

As I have posted above, we have not even seen Jim's line stats. This would make it impossible to try and establish what is actually occurring with the line and connection.
I thought about that straight after posting (actually meant to put that bit in my op ) and then spotted your post when I was going to edit my own. Was too quick on the keyboard there after watching a rather entertaining Fullham vs Chelsea match on my lappy.

BT Infinity2:

Slow Broadband Speed

Hello Whom May Consent
I have just found out that I am not the only one have problem with BT broadband speed. Many people seem to have problem with their slow Internet speed due to the exchange problem. That’s good, because after 10 calls to BT, I still don’t know what the problem with my broadband. So let me tell you what the problem is.
My Internet speed suddenly got very slow (0.4mb) since the morning of 05/11/2010. I thought this was just temporary problem with the Internet speed and nothing should be worry about. The next day, I still face the same Internet speed (0.4mb) which is ridiculous when you pay 25 pound per month. Therefore I took action and made a call to BT customer service. I am sure I dial the right number to an “ENGLISH” company and somehow the line goes to INDIA. Strange~~~
The guy on the phone question me 10mins to check my identity and ask me lots of stupid question like have you try to connect your computer with wire instead of wireless or have you try to change the filter for my Internet connection etc. In the end, the India guys on the phone told me after 24hours my connection should back on the normal speed (5mb). Guess what, it didn't’t.
Clearly I was very angry and made a call back to “India” again to find out that was the problem with my Internet. This time the India guy on the phone seems to know the problem and very helpful. He told me that there was engineering work by my area on the “BT Infinity” which slows my broadband down and this work should be done by Friday 12/11/2010. The India guy even made a promise that he will call me back on Saturday morning 13/11/2010 to check the Internet speed.
Guess what, the India guy let me down. Not just he breaks his promise that he didn't’t call, my Internet speed is still 0.4mb. I was so frustrated at this point and made the call to BT for the third time. I went through the same procedure (10mins of ID check) and this time India guy told me there is a problem with my local exchanger and will get the engineer to fix it. Again, he promised me that he will solve the problem within 24hours.
Sadly the problem is still unsolved. I called BT again. The India woman on the phone told me this time she need to send an engineer to my house on Tuesday on 16/10/2010. At this point I was so angry that I said something very bad to the India woman (I am sorry) but still agree to wait for the engineer to come to my house all morning (missed all lectures).
Long story short, engineer comes and nothing has changed and today 20/11/2010, the engineer comes again to try and solve the problem with my Internet speed. What all his done is change my telephone filter and nothing has changed. Internet speed is still is still 0.4mb. I have been told by the India guy on the phone after the engineer visit that my line is been investigated by the engineers and the engineer will call me tomorrow 21/11/2010.
I just hope this time the problem can be solved otherwise I will cancelled the BT broadband and get my money back for this month’s broadband usages.
PS if they charge me any money for the engineer visit, I will make sure who ever pickups my complain call to feel suffer

Seriously slow 3G speeds

Hello, I'm writing to inquire about some seriously slow 3G speeds. Have been having problems with sluggishness downloading apps on my android phone (EDIT: Original Motorola Droid) from the market so me and a friend got together to do some tests. He is on AT&T and has a Nexus One android phone. We tested multiple locations around the state of SC, in every situation even though I had stronger signal strength (in each test I was between -73 and -86db signal he was between -88 and -96) he always had faster download speeds. And not just slightly faster, he obliterated my speeds. In one locaiton, I had -73db signal, he had -94db, my download speed over 5 tests averaged 40kbs, his average 1842kbs. Almost all the test results are like this the closest test was when I averaged 621kbs over 5 tests, and he averaged 1402kbs. My average over all tests (50 tests in 10 different locations in sc, 5 tests per location) was 223kbs, his was 1561kbs.
Is this the norm for verizon's 3G speeds? If so I may have to strongly consider opening an AT&T account.
EDIT: Added phone type, verizon is my service provider obviously.
Also to note, all speed testing was done using the SpeedTest.net application available in the market. We always used the Columbia, SC server for consistency.

I didn't know what PRL was but looked it up and found it, it shows 30058, I called *228 and did the roaming update to make sure it was up to date, and it did not change so assuming that is the most rescent version for my area.
Researching on the net some it looks like this is an Alltel PRL version. This is probably due to the fact that I was with Alltel before it merged with Verizon and have not converted to a verizon package.
I downloaded that Real Signal app, where I'm at atm my EVDO signal is -3.
Speedtest.net down results
Columbia, SC: 147kbps
Sumter, SC: 168kbps
Atlanta, GA: 236kbps
Charlotte, NC: 223kbps
Average: 193.5kbps
We found the issue. You have an Alltel PRL. I have one also, I think it is 40043. Until the area is combined you will have issues. My SID is now 21 which is a combined SID. So here my phone looks for a Verizon or Alltel tower as level one.With a Smartphone you should not have a 3xxxx PRL.
Once I leave this area and got to wherre there is not a combined area, my phone looks for an Alltel tower first, then a Verizon tower.

Time Capsule as router slows download speeds

Hello,
Over the past couple of months I have been having intermittent internet connection issues where my download speeds slow down from 50mbps+ (Comcast) to under 1mbps, per speedtest.net
I assumed it was a Comcast issue and contacted their support several times. They sent a technician over who had the line reset and that seemed to fix the problems, but a couple of days later it was back. Contacting support again, they had me test the speeds connected directly to the modem (Motorola Surfboard SB6141 DOCSIS 3.0). Connected directly to the modem via Ethernet, I reliably get 50mbps+ download speeds, but using my 4th Gen Time Capsule as a wifi router slows the speeds down to under 1mbps.
After doing research on these and other forums and finding people with a similar issue, I ran the gamut of potential solutions: changing DNS servers, changing wifi bands and channels (2.4 and 5ghz, all chanels tested), changing Time Capsule firmware versions (7.6.3, 7.6.1, and 7.6 are the only versions available for my 4th Gen TC).
I eventually tested with an ethernet cable plugged into the Time Capsule and have the same frustrating issue when directly connected to the router, which means the issue is with the Time Capsule functioning as a router but isn't WiFi specific.
Upload speeds are a consistent 10mbps+ wether I'm connected directly to the modem or using the Time Capsule as a router, even when download speeds are slowed to a crawl.
I purchased my Time Capsule 1 year and 2 months ago, so I no longer have AppleCare for this purchase. I am out of troubleshooting ideas and am on the cusp of purchasing a second wifi router if I can't find a way to resolve my issue.
Thanks for your help!

I can make a couple of suggestions..
You will need to install 5.6 utility on at least one computer.. if you don't have it available already.
1. Replace the ethernet patch cable from the modem to the TC.
2. What I want you to do is lock the speed of the TC WAN port to 100mbit full duplex.
This is only on the v5 utility.
Another method of doing the same thing is putting a small switch between the TC and the modem. Fast ethernet type would be best.. that will force the connection down to 100mbit.
You can also test with half duplex but that would indicate a major problem if it worked.
3. Make sure ipv6 is local link only.. there is no way to turn it off.
Having done those things.. I do note the TC lacks diagnostic and control tools in the firmware, to understand the issue. If those steps do not fix it is likely nothing will.
There is something fundamentally wrong in how the TC is handling routing.. maybe IPv6 getting in the way .. ?? Unfortunately there is simply not enough controls.
The fact that ethernet is affected in this way (though I would do the test with wireless off.. and ipv6 off in the computer as well).. there is little other choice but to get another router.
The TC can be relegated to bridged on the new router.. and still function fine for backup and wireless network for your local network.
If you have applecare on a computer it will still cover the TC.. but I think you may have issues proving the problem.. ie if you take it to apple it will work perfectly.. If you read this forum as I have done.. the SB61xx series modems seem to be a common factor. There is nothing wrong if you test to the modem from the computer but the SB Motorola modem and the TC are incompatible in some way.
I would like you to report the difference in gateway..
When you plug a computer directly to the modem..
Can you please do a copy and paste from Network preferences of the ip and gateway values.
ie this stuff.
Then I want you to get the same stuff out of the TC when it connects.
So we can compare the gateway (Router in applespeak) and if they are different.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 (now 6.2 if you updated) so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.
For screen shots see this post.

Possible solution to slow upload speed

After my old home built rig died I built another. Speedtest.net consistantly showed at least 75/75 with old rig and new one was 85mb down and only 35mb-40mb upload. Having seen this in the past I explored. Old rig used onboard Atheros network interface card (aka 'NIC'), new rig has onboard Realtek NIC.
Problem: Slow upload speeds but only after computer has been unused for a period of time. We all do this.
Note: Every single Windows install by default has "'Power Management" turn off the NIC when not in use. To disable NIC power down go to driver properties "Power Management" tab and uncheck all boxes.
After ruling out the obvious - Your PC, Router and Verizon tests, and have flushed your browser cache and DNS, here is the most likely problem causing intermittent slow upload speeds:
TEST 1: Upon complete computer reboot (not sleep or hibernate) up and download
             speeds are ok.
SYMPTOM: Computer first powers down (after whatever minutes power settings are set
                    at) and is then woken up.
1) Newer Realtek NIC drivers have three settings of interest under the 'Advanced' tab.
       1a) "Energy Efficient Ethernet" Default is 'Enabled'. Set to 'Disabled'.
     1b) "Green Ethernet" Default is 'Enabled'. Set to 'Disabled'.
       1c) "WOL & Shutdown Link Speed" Default is "10 mbps First" Set to "Not Speed
              Down".
2) Problem occurs when computer sits unused then NIC powers up again to the "10
    Mbps First".
3) Though the NIC will eventually uprate to higher speed, it will start at lower rate thus
    causing the problem.
4) My old Atheros NIC driver did not have the driver settings to save power and the
   Realtek one did.
5) Other NIC manufacturers may or may not have driver based power settings. At the
    very least go in the "Power Management" settings and uncheck boxes so NIC never
   powers down.
Common problem many do not think of in todays 'instant gratification' society. This happened way back in Win 3.11/95 days and continues to this day in all Windows OS's.
Hopefully others find this useful. And yes I shared this with Tech Support for their peer review process. Even if this works for some not all this is a common problem many tend to forget.
~Peace

Did it make any differnce to your speeds?
I have had this same issue on 2 systems for a year or so. Both have the same realtek nic built in on the mobo - Realtek PCIe GBE Family Controller. Both systems have the same issue with speeds. have a 75/75 connection they both show a consistent download of around 83 and upload varies between 5 and 15. I've tried changing drivers and got the same results. Made the changes you noted and no difference. I figure it's a mobo problem. I added intel nics and that made a little diffrence - got the upload speed up to about 30. As I have other systems that work fine - consistently about 83/85 - I just finally ignored the issue and never bother doing uploads on the defective systems.
Would be nice to know the answer though.

WRT310N Playstation 3 Slow Download speed and general lag

Hey guys, I just recently bought the WRT310N and got both of my computers working with it. One is wired directly into the router, while the other is running off wireless. My Playstation 3 is able to connect to the router but I am getting an extremely slow connection speed.
Right now, both PC's get about 6.4-6.5 Mbps download speed while my Playstation is anywhere from 600 Kbs to 1.2 Mbps. I have plugged in my Playstation 3 directly into the modem and got a speed of 3.2 Mbps and was downloaded a demo very fast, but I do not recieve anywhere near those results when using it wireless.
Any advice? I have tried opening the ports, but that only seemed to slow it down. A couple of days ago I opened the ports specific to the game NHL 10 and for two days I was getting such a good speed in the game that it felt like I was playing offline, which was great! Then this morning, it just seemed do a complete 180. Now when I play the game I get an extreme amount of lag, and my other games like CoD4 get random lag spikes. Like, I'll be running and I get a lag spike which seems to happen fairly consistently every minute or so.
Any advice? Should I try opening the ports again or what?

I think you need to adjust the wireless settings of your Router, The wireless settings on your Router must have been setup to its default that's the reason you are receiving low signal strength on your PS3.
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...
For Wireless Settings, please do the following : -
Click on the Wireless tab
- Here select manual configuration...Wireless Network mode should be mixed...
- Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WPA, For Encryption, select TKIP...For Passphrase input your desired WPA Key. For example , MySecretKey , This will serve as your network key whenever you connect to your wireless network. Do NOT give this key to anyone and remember the key.
NOTE : Passphrase should be more that 8 characters...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...

External hard drive, error -36, corrupt files and slow transfer speeds

This is a long post but stay with me.
I've got an external 250GB Lacie drive connected to my 24" Intel iMac via Firewire 800. I have approximately 80GB worth of files (including my iPhoto library) on the Lacie that I'm trying to move over to my iMac but have run into some frustrating problems.
Overall, transfer speeds are erratic – fine at times and SUPER SLOW (5 minutes to transfer a 3MB file) at other times. At first I was transferring entire folders, but after always getting errors (error -36 to be exact), I was having to transfer individual files. This works fine as long as the files aren't too big (which makes the transfer speeds SUPER SLOW) and not corrupt (which gets me an error -36). Is my Lacie crashing on me? Is there any hope?
Here's what I've done to try and salvage my sanity with no resolve to my problems (not exactly in this order):
1) Ran Disk Utility to repair Lacie. Everything came back OK
2) Ran Disk Warrior on Lacie. Found a handful of bad items that Disk Warrior was able to repair. Had Disk Warrior replace the old directory of the Lacie with the new directory.
3) Ran Drive Genius: Raired and Rebuilt the directory, did an Integrity Check (came back OK), attempted to Defrag but could not because of errors to the drive, did a Scan for bad blocks (which after running for 3 days! it was only 20% complete and had found over 150 bad blocks, at which point I quit to try something else)
4) Checked that my Firewire cable was properly connected and replaced the older one I was using with a brand new one.
5) Disconnected all peripherals except for keyboard, mouse and Lacie.
6) And at times, even viewing a file on the Lacie has caused my Finder to crash, requiring a restart of my iMac.
I'm sure I've left something off I've tried but you get the idea.
I've read that maybe I can transfer my files using Terminal. Yes/No? Does this bypass any corruption the files may have?
What about creating a second partition on the Lacie and moving files over to the second partition? Does this solve anything? I don't know anything about partitioning so maybe I'm talking crazy.
I've also read that iPhoto tends to corrupt files which makes me hate iPhoto, and myself for not backing up.
And I've read a lot about error -36's and none of it sounds good so I'm just hoping that someone might have other suggestions for me to try and save my files (especially my iPhoto files which include baby pictures that if I lose, my wife will kill me).
So if anyone has any ideas, let me know. Please. I'll try anything.

Hi Aaron Thompson-
I am fairly certain you have a bad power supply brick to the LaCie drive. This is a hard problem to troubleshoot as generally when the bricks go bad they do so slowly and the drive appears to power up and stuff but it just doesn't work.
If the drive is under warranty LaCie will replace the brick at no charge. Otherwise they sell them for around $20US on their website.
Luck-
