E3200 - Dramatically slowing speed with a switch behind...
I changed my old Linksys router with a new e3200 with gigabit eth-ports.
When i directly connect to the router (ethernet) i get the right speed. (speedtest @ 98Mbits)
But the crazy thing when i put a switch (non gigabit) on my router and connect my pc to the switch
i get a really bad connection. (speedtest @ 18Mbits).
Tested different times and still this slow speed..
When i connect the pc directly to my router i get the right speed again.
I tried everything but cannot find a way to fix it.
In my old sitation i got the right speed. That was also a linksys, but older model and non gigabit.
The only last thing i think:
maybe a conflict between gigabit(e3200 router) and the non gigabit(switch).??
Thank you for you response!
I didnt change anything and before my new E3200 router everything worked OK.
I was getting speeds round 100 MB/S on speedtest.net
But saturday i switched the old switch (non gigabit) with a New Gigabit switch (Sitecome).
And now everything is back to 100 MB/S.
So conclusion:
Dont use a non gigabit switch with the E3200. Cause it wil conflict.
I tested 3 differtent non gigabit switches and all gave me lower speed. With my Fiber connection and saw immediately the problem.
People who normaly not get speeds above 20MB/S on internet, dont sees the problem.

My podcast app started playing all unplayed episodes at slightly slower speed with everything doubled. How do I return it to normal play?
When you're listening to a podcast, slide the current artwork up from the bottom, and you will reveal the control panel. Adjust the little switch in the middle so that it is pointing North, instead of Northwest. That will fix your problem.

2.4GHZ clients very slow speeds with AP3600
5508 WLC (7.5.102)
AP36021
We currently have a test WiFi SSID setup that uses basic mac filtering on our WLC's
WLAN is configured with WPA and WPA2 L2 Security with WPA Policy and WPA2 Encryption.
For some reason we seem to be getting very slow speeds on clients with 2.4GHZ
for example speedtest.net I get 70mg upload and 65mg download on 5GHZ devices and about 1-3mg download and 1mg upload for 2.4GZ devices!
AP36021 are dual band with 4 channels (2 x 2.4Ghz and 2 x 5Ghz)
fyi - There are no dropped packets on the client stats via Prime mgmt that use 2.4GHZ
Any ideas here?Foreign Primary WLC (let me know if you need the Anchor controller ouput as well)

Slow speeds with roaming network
I just got a new HTC One M8 which has the wireless AC capability. I am getting really slow speeds on my home network and hoping someone can help.
My current setup is as follows - a motorola surfboard modem hooked up (ethernet) to the new model Airport Extreme (with the AC), from there I have a powerline adapter hooked up to another part of the house where I have the older model Airport Extreme (I think 5th gen) - and I am using this in roaming mode to extend the signal.
This works fantastic for my devices which run on N, and everything flies with little to no issues no matter where I am in the house. But this phone - it is incredibly slow. When I run speed tests, at times I am getting decent download on the phone (20mbs) but getting absolutely 0 upload (literally 0.0 mbs). It works from time to time but is cutting in and out frequently.. So - What I am wondering is, would the fact that the router downstairs broadcasting an AC signal conflict with the upstairs broadcasting an N? I am wondering if the phone is constantly switching from one band to another and causing my speed issues? I tried the wifi on another network which just had an N signal, and had no issues whatsoever so I know it is something to do with my home network.
Again - I don't have this issue with any of my other devices (iphone 5, laptop, Ipad etc) so I don't believe the issue lies with my ISP, just looking for advice or if anyone knows if this setup would cause issues with AC devices? I like having the 2nd router upstairs as it really boosts the signal for my N devices and also gives me the ability to hard wire the PS4, xbox etc - so I definitely want to keep it setup - but am thinking I might need to set it up as a new network and turn off the roaming.. Thoughts? Thanks in advance.i'd tweak it and think you're making it worse by having 2 different networks, both your routers are very capable dual mode so you should let the router and the devices decide which band to use (2 vs 5) vs your choosing it for them
once your network is setup correctly, restart any stationary clients ensuring that they are grabbing the strongest signal present
keep flatex downstairs, factory reset it and create a new network, trust me you'll want to factory reset to avoid issues when setting up the towerex
for now, put towerex next to flatex, factory reset it, and connect an eth cable from LAN on flatex to WAN (circle icon) on towerex
give it a minute or 2, open airport utility and you'll get the option to setup towerex as a WIRED extension, do this
now the painful part, play around with different set of electrical outlets to find the ones that give your towerex the best connection
remember, to turn the wifi on/off for the device you're using to test the towerex after each move or it will likely be connected to the flatex -
Mac mini slow speed - with pauses
My Mac Mini crashed and I had to reinstall.
Now it runs partly very slow, even with pauses, where I have to wait for responses.
Start-up takes long minutes.
System profiling tools says HD activity reaches a max of 8MB/s.
CPU workload looks far below 100%.
Is there any experience with this?
How can I check and find out more precise the reason for slowing down?
Mac Mini: 4GB 1067 MHz DDR3 RAM, 500 GB HD, 2,66 GHz Intel Core 2 Duo, OS X 10.7.2 everything updatedAs per the reply to your other post with the same question:
This is not something to worry about or be concerned with. Firstly, the paging counts will depend on how long the system has been running since the last boot, but MacOS is designed to actively page out and in, so in itself, the fact your system shows it is doing so means nothing at all.
If your computer is exhibiting some indication of a problem, I suggest you start a new thread here and describe what you are experiencing. That way we can help you directly with the specifics of your problem. On the other hand, if you have just seen the comments regarding paging and system performance and have checked your own Mac to see what it's doing - the answer is that in the absence of an indication of a problem, it's very likely doing exactly what it ought to be doing! -
Slow speed with non BT modem/routers
Hello,
For several years I have had a BT broadband ADSL line to my rural property. My normal speed is between 1.5 and 2.2mbps. The maximum speed ever seen was about 2.5mbps and my IP profile is set at 2.4.
I recently decided to replace my ageing BT home hub 2 in the hope that a more modern router might get a little more speed out of the line. I started with a Netgear DGND3300. This worked fine but only produced 1.5mbps and a noticeably slower service. I contacted both BT and Netgear. BT told me there was a fault on the line, so I connected the router to the test socket with a filter and left it two days. Speeds stayed the same. BT tell me my line is now fine but frankly there has been no change to speeds.
After altering the MTU to 1458 and power output to 300mbps at 2.4Ghz nothing altered the fact that the BT hub delivers a little over 2 and the Netgear 1.5 at best.
Netgear have finally told me to exchange the unit as faulty which I did yesterday and replaced it with a Linksys X2000. The results are exactly the same. 2+ on the BT hub but even worse on the Lynksys at 1.4. This was measured at different times of day and on three computers and an iPhone with all of them showing near identical results in different parts of the house.
I have given up on the BT support centre as all I get is an asian service telling me to start again with the test socket so they can tick off their checklists and I waste 10p a minute! Apart from SNR difference this seems like a product issue and I'd like to know why my BT hub delivers a better speed than more expensive units. I don't mind living with it as I only need a wirelesss surfing network with light file transfer duties, but what happens when it finally dies of old age?
The one thing I am intrigued about is the fact that when I use the BT test page with the BT hub my maximum speed is marked at 4mbps but with both the Lynksys and the Netgear it is marked as 2mbps.
Is there any way I can get a new router to replicate the speed of my current hub? Would buying a HH3 be the answer? However since I am already out over £100 I do not wish to purchase yet more redundant harware.
Any help appreciated.
Solved!
Go to Solution.welcome to the BT community forum where customers help customers and only BT employees are the forum mods
in order for the forum members to help please can you post the adsl stats from your router may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z, if netgear enter 192.168.0.1) and run btspeedtester (MAC users may have problems) bt speedtester and post the results .
are you connected directly via a filter to the NTE5 master or test socket or to somewhere else? Is the master the only phone socket in your home?
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
if you have a long line the bt business router 2700hgv is recommended by many on the forum
Someone may then be able to offer help/assistance/suggestions to your problem

Very slow speeds with Mac Pro talking to a Ubuntu Raid Server
So I have an environment where mainly macs and a couple Windows PCs use a Ubuntu Raid 50 file server. When attempting to access the server the Mac Pros take typically 1 minute to view the file structure and sometimes timeout, the Windows machines take about 1 second. Also this seems to affect copying and deleting which takes much longer from the Mac side. The server is setup simply with a samba mount to allow access.
Any suggestions for how I can attack this issue? Any help would be greatly appreciated.
ColinNope. The Macs and PCs are on the same subnet and plugged into the same switch, from the wall.

I have FF 18 on my computer. With IE it is no problem.
With FF speed catch 4,74 and send 1,76.
With IE speed catch 17,67 and send 4,67.hello janlun, are you using speedtest.net or a similar flash-based site to measure your connection speed? then it might be an issue with the protected mode that [http://blogs.adobe.com/asset/2012/06/inside-flash-player-protected-mode-for-firefox.html adobe has introduced] for its flash plugin for firefox. some old versions of f-secure or trusteer rapport are known to cause such slowdowns together with flash, or it might be something similar on your system that is interfering (maybe security software that is blocking/sandboxing the container used for the protected mode, etc...).
as a workaround you could try [https://support.mozilla.org/en-US/kb/flash-113-crashes#w_solution-2-downgrade-to-flash-10-3 downgrading to flash 10.3] (which is still supported) or [http://forums.adobe.com/thread/1018071#TemporaryWorkaround disabling protected mode] & see if this makes a difference.
in case you'd like to troubleshoot the issue further, it would be best to contact adobe's support & file a bug report at bugbase.adobe.com (choose "Adobe Flash Player" as the product & "Browser Integration" as the product area), since they will have a better understanding of the internals of flash protected mode & therefore may know what else might be at the root of the problem you were seeing. -
Slow speed with WRT54GS Wireless-G router
I have install a WRT54GS wireless router.
Since then my download speed on my pc (the one directly connect with the router) has come down from 4mb to 1mb.
If I connect the modem directly to the pc I get 4mb but when i connect the wireless router between them it goes down to 1mb.
I have call tech support, upgrade to version 1.52.0 but nothing change.
I have try it without a firewall and get the same result
One thing I have notice, when I do a tweak test at http://www.dslreports.com my RWIN without the router is 56000
If I connect the router is show 9800 even if my PC who as XP is set to 56000
ThanksCheck for latest firmware and upgrade if necessary. Then do a factory reset.
Help fight lag! Wire up that gaming machine!!!!! -
I recently purchased a WRT160N wirless router to upgrade from an old 802.11b that I've had forever. I set it up with WPA2 Personal Security with TKIP encryption. My PC is one floor away from the router, which I understand will cause some signal degredation.
My PC has a linksys wireless-G NIC.
I have been experiencing varying connection speeds to the router, when first booting the PC it will report connected at 54Mbps reading a Very Good signal strength, but it will eventually sink to around 10-5Mbps reading a Low signal strength.
I'll be honest, my connection speeds in games are no better than with my crappy old 802.11b router, now you would think that I would experience at least some improvement.
Has anyone else experienced similar problems or have any suggestions?Possibly the WRT610N is not working properly with G devices .... keep the router away from the computer or PS3 ... & then check the connection speed .....

Slow Internet Speeds with Airport Extreme
I am noticing a dramatic slow down with my Airport Extreme. However, I have noticed this is an intermittent issue. Here are the specs of what I am running:
• Airport Extreme Base station that is plugged into a cable modem. The AEBS is routing the IP addresses.
• Plugged into the AEBS is an 800mhz iMac that is hardwired in. No slow down is noted on this computer.
• MacBook (Less than 2 months old) is connected to the AEBS wirelessly.
• iPhone is connected to the AEBS wirelessly.
Where I am having the problems is with the MacBook. I will have full signal strength and yet it takes for ever to load a page. Plus sometimes the connection will time out. As stated above this is an intermittent issue. Sometimes everything works fine, other times the connection has issues. All pieces of equipment are running the latest firmware. Does anyone have any suggestions to solve this issue?I would recommend changing the wireless channel of the Extreme.
Open Airport Utility, and select Manual Setup. Note on the summary page what the channel is set to, most often it will be set to channel 6 (Automatic), but it could be anything between 1-11.
Goto the Wireless tab and adjust the channel so it several channels apart from the current one. If it is on channel 6, I recommend channel 1 or 11. -
K9N2 Sli Platinum + SSD OCZ Vertex 3 = Slow Speed Problem [PARTIALLY SOLVED]
Hey folks,
I have a problem with my new SSD. I only get sequential reads of 140MB/s and writes of 114MB/s.
I think it is a driver related issue. I once got faster SATA2-like speeds but cannot reproduce the system settings again... Everything back to SATA1-like speeds after reboot.
First my pc specs:
MSI K9N2 Sli Platinum, BIOS v3.9
- 6 SATAII ports by nForce 750a SLI
- 2 ESATA (External-SATA) ports (back panel) by JMB363
- Supports storage and data transfers at up to 3 Gb/s
AMD Phenom II 965 Black
Patriot PV224G8500ELKB Viper II Series DDR2 4GB (2 x 2GB, CL5 PC-8500/1066MHz)
SSD SATAIII OCZ Vertex 3, 120GB, FW v2.11
LG Internal BlueRay BH10LS30
Windows 7 Ultimate x64
I only get very slow speeds with the SSD. I tried so many things that I am getting very frustrated now, I am even thinking about getting a new board and ram just to get the SSD up to speed...
1)
I installed Win7 first with all the default settings in Windows Setup from DVD. Default "IDE ATA/ATAPI controllers" driver was "Standard AHCI1.0 Serial ATA Controller".
SSD was connected to SATA1-port, On-Chip Sata Controller AHCI enabled in BIOS, Extra RAID/IDE Controller disabled.
All fine, but whichever benchmark I used (AS SSD, HD Tune Pro, Atto Disk Benchmark, CrystalDiskMark; other tools used: DriveControllerInfo, AIDA64/Everest, CrystalDiskInfo ) I got e.g. 140MB/s Read and 114MB/s Write sequentially (CrystalDiskmark, similar with random data AND only zeros ).
Trim working (it seems) with AHCI driver. I also changed to nvstor64 driver (nforce driver setup 15.56), with is marginally faster but not what you would expect from a SATAIII drive on SATAII controller.
2)
I installed Win7 using "diskpart" (Shift-F10) during disk setup, setting a cluster size of 64k instead of default. No real change.
3)
After reinstall of Win7 x64 (again...), I changed from SATA1 port to SATA6 port, also enabled Extra Raid/IDE controller set to AHCI as well.
Nothing changed. With all settings to default in Windows (ahci default driver), I then manually updated the ahci to nvstore64 driver in Device Management, rebooted.
Then a minute later after reboot I got the following Sequential speeds with CrystalDiskMark:
273MB/s read and 137MB/s write (random data) + 274MB/s read and 220MB/s write (with zeros) !!!
While I ran this benchmark Windows came up with a message: "You must restart your computer to apply these changes - Restart Now/Restart Later".
After the previos reboot, when I changed manually from AHCI to NVSTORE, I had changed nothing in the current session, apart from running CrystalDiskMark.
I did reboot and I was back to the slow SSD speeds again = 140/114 MB/s...
4)
I have tried every possible combination of mainboard SATA ports, drivers changing with nvidia setup/manually, deleting and disabling controllers (incl BSOD and startup repair :D ), chaning bios settings around, but I just cannot get back the faster speeds
There is never any change in speed, whether I use ahci or nvstore64, whichever benchmark I use, whether random or zeros...
5)
Could the SSD be broken, something internally preventing it from faster speeds (with this one random exception)?
Could it be that my K9N2 SataPorts only allows for / reduced to SATA1 speeds?
Am I missing something with the driver setup?
Do I need additional drivers for the extra JMicron Controller when using SataPorts 5/6 ?
I have no other mainboard to test this with...
Please guys, I am going to jump out of the window if I can't fix it... :(
Thanks, MikeHey guys - problem 'solved':
I tested the OCZ SSD Vertex 3 120GB with following sata3 controller card http://www.lycom.com.tw/PE-115H.htm.
The card itself works immediately (needs at least PCIe x4 slot, will work slower otherwise but still faster than the OCZ SSD @sata1 with nvidia chipset).
There is some raid setup, doesn't apply to me, the boot even with the card is really only a few seconds longer and not annoying at all. Windows (7 x64) needed a driver, supplied on CD (which is cheap and making noise like h**l). The card works w/o the driver but doesn't harm to install it...
Also, just to clarify, this sata controller card did not need any specific setup at all. Just put it in, plug in sata cable (I use akasa sata3-rated), maybe change boot device in BIOS (I didn't even have to), done - booting Windows as usual.
Benchmark CDM with sata controller card Lycom PE-115H:

Speed is much better than before with nvidia chipset 750a SLI controller: sata1 (sata2 whenever it randomly worked):

http://img13.imageshack.us/img13/6258/cdmahci0x0sata6contnv64.png
Final thoughts:
Well, I am happy with the SSD speed now (PCIe limited to 5Gbps). However, I had to spent quite some time to get it working on my sata2-cabable mainboard. Finally, I had to buy a extra controller card to get it working reliably at speeds faster than sata1. There is hardly any useful information on why this problem occurs with (older) nvidia chipsets and OCZ (sata3) SSDs. I still think that OCZ must know about this problem, but regards this issue as low priority, while at the same time not planning on giving up on sales to people with nvidia chipsets. Maybe OCZ should just make a big sticker on the box the drives come in with something like "Does/Might not work with nvidia chipsets, please use third-party sata controller card or different SSD manufacturer". But then none of these potential customers would buy OCZ SSDs...
I will keep the sata3 controller, anyway handy to have, but return the OCZ Vertex 3 120GB and replace it with a SSD from a different manufacturer (Corsair Force GT, Patriot and OWC are not that great to get around here). The benchmarks for most people will not achieve the maximum advertised OCZ speeds anyway, so why not go with a brand that allows for some plug'n'play with some customer support.
Hope this post helps others like me with their nvidia chipset + sata1 speed problem
Cheers, Mike -
Slow performance with macbook pro retina
Saving an image (JPEG) with my lightning fast new macbook pro 2012 retina edition takes 30-60 seconds. Any ideas why? Mountain lion Mac OS, 8GB RAM. Can't upgrade RAM but shouldn't have to! I moved images to external hard drive since I was filling up memory on laptop quickly. I would appreciate ideas from anyone who knows Elements and Mac . Thanks.
This is my only computer now. Will check into auto analyzer (never heard of it). This is Elements 11, not the whole photoshop. It is the regular, not app version. I did move some of the photos from a past pc to it, but it seems to have the same slow speed with new photos as well. I installed Elements 11 on my mac with a disc. When I bought it, it came with both pc and mac discs. A guy at the apple store had me move all the photos onto my external hard drive. Its a new Apple 3 TB external hard drive. I actually tried to increase the RAM at the suggestion of my camera club friends who had similar problem and got relief with increasing RAM of 4 up to 12 or 16. Mine is 8 and can't be increased.

Hit my record with BT's ridiculous slow speed.
Once again, slow speeds for no reason.
Probably because of their "remote" adjustments to my line - that's how they fixed my speed problems before anyway.

Without doubt, this is the worst speed and ping I ever, EVER had. Worse than dial-up. Thank you, my weekend has been wasted.I can't take BT seriously anymore, it's a **bleep**ing joke.
A guy threw my mail through my door, I went to pick it up, then went back to my PC and what do I see?

So, my theory is this. The vibrations the guy made with his attempt to slip the mail caused BT line go ape**bleep**, thus completely ruining my broadband for this entire day. Quality, top notch quality.
Update 1: I used the test socket behind the plate, the result:

Still not perfect though, the ping goes up and down randomly (from 50 to 1400). This is going to be a lot of fun.
Update 2: Just to show you how random it is, here a few more tests:

For your connection, the acceptable range of speeds is 600-7150 Kbps.
Additional Information:

Switched to BT, now getting really slow speeds
Hi, I moved to BT yesterday from EE. I've noticed that since the switch over, my speed has fallen drastically. Whilst I didn't check speeds on the old EE connection (it was running fine with multiple devices logged in throughout peak times & I never had cause to check), it was definitely much quicker. Now I'm on BT, I can't download anything, or watch video on demand. I've even taken to checking all my e-mail on my iPhone because outlook seems to take forever now. I've done a speed check, and I'm getting 0.24MB wired, 0.20 wireless (next to router) and 0.18 wireless in another room. This was without any other device connected. Can anyone think of any reason for the dramatic fall in service from switching broadband provider and anything I can do to fix it? To save time, I'll mention that my phone socket does not have a test port. Also, in case this does not pan out, does anyone know if there is a 'cooling off period' in which I can cancel and return BT's router? Thanks, Harry
welcome to the BT community forum where customers help customers and only BT employees are the forum mods
in order for the forum members to help please can you post the adsl stats if HH4/5 then go to troubleshooting then logs and you are looking for 2 line together when hub last connected to internet and they will show your connection speed and noise margin or if netgear enter 192.168.0.1). Then run btspeedtester (MAC users may have problems). when first test completes then run diagnostic test and post the results ( do not reset the router).
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
Someone may then be able to offer help/assistance/suggestions to your problem

Why do I have so much trouble syncing?
This is really starting to get on my nerves. I bought this iPhone because of all the cool stuff it can do and because it was supposed to be more reliable "because it's Apple." So far, I've had fewer complaints about the copy of Windows 7 that I bough
