Evenings and weekend speed getting near unusable

So 6 months into my contract and things are starting to get a bit silly. I have a sync speed of about 14mb down and on an average day I get speeds anywhere between 12~13mbps which is fine, perfectly reasonable.
Ever since about 3 months ago my speed has been dropping like a brick some evenings and almost every weekend, straight down from ~12mbps to somewhere between 2 and 3mbps. This certainly isn't due to my own traffic as what I do doesn't have any effect on the speed.
Calls to BT helplines have been met with frustration, on 5 calls to them I've restarted my router/pc/pc-in-safemode/microwave/boiler to no avail (suprisingly), line tests have shown diddly squat, and escalations to level 2 have been met with an excuse that "well the speed is fine now" the following day.
Is this just your regular old contention? Why is this still an issue? My speed has been dipping below my 3mbps guaranteed speed, can I use this as justification of contract cancelation without early termination charge?

BT Infinity evening and weekend speed drops

Hi,
I have a BT Business Hub 5 and Infinity package.
My connection during the working week in the day is usually around:
27.95MB/s down, 4.63Mb/s up and a ping of around 20ms.
Often in the evenings and on weekends the speed drops to around:
1.5MB/s down, 4.5Mb/s up and a ping of anywhere between 20ms and 60ms
I called up BT Business suport and raised a ticket to only have an email the next day stating your issue has been resolved, however it has not been resolved. Obviously they done a test in week day during the day when it is usually fine and not in the evening or on the weekend.
Basically my old 8Mb package from BT was often faster in the evenings and on weekends, with a typical connection of:
3.5 to 5Mbps down and a 0.35Mbs up, ping times were between 20ms and 120ms)
This translates to if I was on my old 8Mb package from BT I could download at around 720Kbs max during the evenings and weekends instead of 160Kbs.
Anyone actually got BT to solve this? I've read a lot of posts so far where people are just writing letters of complaint and contacting the ombidsman.
Is there is a resolution to this?
Thanks

Very slow connection in evenings and weekend

For a couple of months we have had appallingly slow broadband in the evenings and at some times on the weekend.
We have two laptops and an ipad which all experience the same issues. Speed tests show 4499kps at some times and, what must be a record-breaking, 29kps at other times. Unfortunately the 'other times' are normally when we want to use it.
Tech support provides some really polite and positive people in India but no continuity, no back-up to promises and some very misleading information. One call led to a guarantee the line would be 'upgraded' within the week and nothing changed. And the number she gave me didn't work.
So terrible broadband speed. Awful customer service. Feeling cheated and will stop paying very soon. Have emailed the moderator this evening but is there anything else to do in the meantime?

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) http://speedtester.bt.com and post the results . This will also assist the mods
are you connected directly to the NTE5 master or test socket or to somewhere else? Do you have any phone extension sockets 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
Someone may then be able to offer help/assistance/suggestions to your problem

Poor internet speed getting slower

The area i live in has a very poor internet speed however in the last couple of months it has got significantly slower, where web pages arent evening loading and streaming is getting near impossible
BT call centre suggested leaving it an hour, then a day then a few days and they would 'fix' something. No change ever happens after these calls and leaving the internet unused for days at a time is getting unacceptable

Which Mac Pro? More cores=slower speeds? And most of us know the speed matters or FPU for music and I don't understand the faster is for the least amount of procs. And while I get the whole rendering thing and why it makes sense.

Which Mac Pro? More cores=slower speeds? And most of us know the speed matters or FPU for music and I don't understand the faster is for the least amount of procs. And while I get the whole rendering thing and why it makes sense.
The above is what the bar says. It's been a while and wondered, maybe Apple changed the format for forums. Then got this nice big blank canvas to air my concerns. Went to school for Computer Science, BSEE, even worked at Analog Devices in Newton Massachusetts, where they make something for apple.
The bottom line is fast CPU = more FPU = more headroom and still can't figure out why the more cores= the slower it gets unless it's to get us in to a 6 core then come out with faster cores down the road or a newer Mac that uses the GPU. Also. Few. I'm the guy who said a few years ago Mac has an FCP that looks like iMovie on Steroids. Having said that I called the campus one day to ask them something and while I used to work for Apple, I think she thought I still did as she asked me, "HOW ARE THE 32 CORES/1DYE COMING ALONG? Not wanting to embarrass her I said fine, fine and then hung up. Makes the most sense as I never quite got the 2,6,12 cores when for years everything from memory to CPU's have been, in sets of 2 to the 2nd power. 2,4,8,16,32,64,120,256,512, 1024, 2048,4196,8192, 72,768. Wow. W-O-W and will be using whatever I get with Apollo Quad.
Peace to all and hope someone can point us in THE RIGHT DIRECTION. THANK YOU

If you are interested in the actual design data for the Xeon processor, go to the Intel site and the actual CPU part numbers are:

I read that the CPU is easy to swap out but am sure something goes wrong at a certain point - even if solderedon they make material to absorb the solder, making your work area VERY clean.
My Question now is this, get an 8 core, then replace with 2 3.7 QUAD CHIPS, what would happen?
I also noticed that the 8 core Mac Pro is 3.0 when in fact they do have a 3.4 8 core chip, so 2 =16? Or if correct, wouldn't you be able to replace a QUAD CHIP WITH THAT? I;M SURE THEY ARE UO TO SOMETHING AS 1) WE HAVE SEEN NO AUDIO FPU OR PERHAPS I SHOULD CHECK OUT PC MAKERS WINDOWS machines for Sisoft Sandra "B-E-N-C-H-M-A-R-K-S" -
SOMETHINGS UP AND AM SURE WE'LL ALL BE PLEASED, AS the mac pro was announced Last year, barely made the December mark, then pushed to January, then February and now April.
Would rather wait and have it done correct than released to early only to have it benchmarked in audio and found to be slower in a few areas- - - the logical part of my brain is wondering what else I would have to swap out as I am sure it would run, and fine for a while, then, poof....
PEACE===AM SURE APPLE WILL BLOW US AWAY - they have to figure out how to increase the power for 150 watts or make the GPU work which in regard to FPU, I thought was NVIDIA?

[Sound Blaster ZX]Control Panel takes 6 MINUTES to load and is nearly unusable?!

All,
Yesterday I took the plunge and picked up a Sound Blaster ZX to replace my old Audigy Platinum. Unfortunately I've been met with a series of problems that leave me with a bad taste in my mouth about my purchase.
The driver install seemed to go well though it was a little disconcerting when the 'Check for update' button in the auto update tool that runs right after install was grayed out. I noticed that I was not getting sound out of the 5.1 analog inputs that I had connected up to my Logitech Z680 speaker system. So I checked the system tray and there was a new SB icon there, that was clearly a utility to get to the configuration. Knowing this was probably the right place to start fiddling with the settings, I clicked it. And waited. And waited. And waited some more.
Strange I thought, so I checked the Windows task manager and located the Sound Blaster control panel in the list of running processes. I waited another minute or so and still nothing was displaying. So I killed the process in task manager, located the shortcut to the SB ZX control panel in the start menu and launched it. Again with the waiting. I immediately took to google and started researching a potential problem with this card.
As I was searching and had forgotten that I had launched the Control Panel, it suddenly showed up on my screen. Wow I thought, that took a while to load. I then proceeded to try to navigate the various areas of the Control Panel application. I was immediately concerned when I noticed that the app was not responsive and appeared to be frozen. I decided to patiently wait to see if it would wake up. Fortunately it did, though only after waiting for several minutes. I then attempted to close the Control Panel app, which it did after several more minutes of waiting.
I thought maybe there was some anomalous process running so I decided to try the Control Panel from a fresh boot. After my machine had started up, I clicked the SB icon in the system tray again, only this time I was going to time it. I recorded that it took 6 FULL MINUTES from the time I clicked the icon until the application displayed on my screen. Further, the lag of switching between the various areas of the application was as high as 3-4 minutes. In essence this software is completely unusable.
I decided to try the TOSLINK connections between my speaker system and the soundcard to see if it would respond better. I set the mixer settings(via the built in Windows mixer) and I could get it to produce sound albiet only in two channel stereo. Progress, or so I thought. So I switched back to the analog connections and there was no difference in the response of the control panel. I had found some instances where an onboard or video card based HDMI audio driver might interfere with the card. I had long since disabled the on board sound of my Asus P5Q Pro motherboard via the BIOS so there were no drivers hanging around from it. I then took a look at the device manager and disabled the ATI High Defintion Audio device that was likely part of my SAPPHIRE 100259-1GL Radeon HD 4870 video card. This had no effect, I was still getting no sound from my speakers and the interface is abysmally lagged.
I then took the following steps to no avail:
Uninstall all Soundblaster ZX drivers and software
Restart machine
Install the updated Soundblaster ZX software from the Creative Support site: http://support.creative.com/Products...T=CategoryID:1
Nothing I have tried has resolved the issue with the virtually unusable lag that occurs when trying to run the Control Panel and/or configure the Soundblaster ZX or the amount of time it takes to start up.
Anyone experienced this and know of a fix or a remedy? I really want to enjoy this sound card.
**UPDATE**
I just wanted to post up and say that I solved this issue by first uninstalling all drivers for both the SB ZX and my Radeon graphics card. I then used Driver Fusion(http://treexy.com/products/driver-fusion) to perform a registry/file cleanup on all files associated with AMD graphics cards and Creative sound cards. Then I installed the drivers & software for the SB ZX from the CD that came in the box. I was pleasantly surprised to see that the software was responsive and the hardware was fully functioning. I then installed the software for my Radeon card however this time, I selected a custom install and chose NOT to install the HDMI audio driver. I don't know if this was key or not but at any rate, after the graphics card drivers and software was installed I am happy to report that the SB ZX software remained responsive and fully functioning.
I then updated the SB ZX software to the version linked above(1.0.22) from the version that ships on the CD - 1.0.13 and strangely the Cinematic tab disappeared from the Pro Studio control panel. Some research revealed that this tab is dependent on the Creative Labs Extras which seemed to have gotten nuked during the update. I was able to bring back the Cinematic tab by re-installing the extras from the CD, however it only installed the Dolby Digital Live component. DTS connect is still missing. I am going to do a little more research to see what I can do to get it back.
Hope this helps someone who runs into this same predicament.

Any news about the SoundBlaster Zx Linux drivers? Currently, there's no way to get even the most basic sound of it on Linux.

What can I delete from what folders to A) get more space and B) speed up machine. 2009 Imac Intel based Leopard

What can I delete from what folders to A) get more space and B) speed up machine. 2009 Imac Intel based Leopard

If you start deleting things in hidden system folders, or in an /Library folder you may very well mess up something.
That is why I say limit what you delete to your User folder only and only those files you've put or created there. Start messing with anything system or application related without know exactly what you are doing and you risk fubar'ing something.
There are in fact many places in the system areas that will appear to be redundant, but they are not so just because they have similar path or file names.
Also, how much free space do you have with just a freshly rebooted system? If your system does not have much RAM (given the apps your normally run on it), it may be creating quite a bit of swap space. That will be flushed out with a reboot, but if your system is RAM limited, then it will just grow back. In such a case, more RAM would help.
Use Activity Monitor to look at your RAM and swap use over a few days of normal use - look particularly at the page outs, as that will tell you how much virtual memory is actually being used on the drive. If page outs are high (thousands to 10's of thousands or more) your system is RAM limited, and your drive will be filling up with swap files.

Getting the next valid date (jump holidays and weekends)

Hello,
I have a column table where I have all holidays of the year in the format "yyyymmdd,yyyymmdd,...", for example, "20091012,20091225".
I'd like to do a query where I pass a date and a increment of days and it returns the next valid date, excluding weekends and the holidays that I have in the column holidays that I show above.
P.S: Instead of pass a date and a increment of days, I could pass just a already incremented date, and this query just validate this date, adding 2 days for each weekend and one day for each holiday.
Is there a way to do that?
Thanks

I'd like to do a query where I pass a date and a increment of days and it returns the next valid date, excluding weekends and the holidays that I have in the column holidays that I show above.For convenience, you can't beat a user-defined function, such as Etbin's.
If you really want a pure SQL solution, you can
(a) generate a list of all the days that might be between the start date and end date (sub-query all_days below)
(b) outer join that to your holiday table (sub-query got_dnum, below)
(c) rule out the holidays and weekends (sub_query got_dnum, WHERE clause)
(d) return the nth remaining day (main query below)
WITH     all_days     AS
     SELECT TO_DATE (:start_date, 'DD-Mon-YYYY') + LEVEL     AS dt
     FROM     dual
     CONNECT BY     LEVEL <= 3           -- 3 = max. consecutive non-work days
               + (:day_cnt * 7 / 4)     -- 4 = min. work days per week
,     got_dnum     AS
     SELECT     a.dt
     ,     ROW_NUMBER () OVER (ORDER BY a.dt)     AS dnum
     FROM          all_days     a
     LEFT OUTER JOIN     holidays     h     ON     a.dt = TO_DATE (txt, 'YYYYMMDD')
     WHERE     h.txt               IS NULL
     AND     TO_CHAR (a.dt, 'Dy')      NOT IN ('Sat', 'Sun')
SELECT     dt
FROM     got_dnum
WHERE     dnum     = :day_cnt
;This assumes :day_cnt > 0.
The tricky part is estimating how far you might have to go in sub-query all-days to be certain you've included at leas :day_cnt work days.
Where I work, holidays are always at least 7 days apart.
That means that there can be, at most, 3 consective days without work (which happens when there is a holiday on Monday or Friday), and that thee are at least 4 work days in any period of 7 consecutive days. That's where the "magic numbers" 3 and 4 come from in the CONNECT BY clause of all_days. Depending on your holidays, you may need to change those numbers.
P.S: Instead of pass a date and a increment of days, I could pass just a already incremented date, and this query just validate this date, adding 2 days for each weekend and one day for each holiday.Good thought, but it won't quite work. How do you know how many holidays were in the interval? And what if the first step produces a Saturday before a Monday holioday?
You might be interested in [this thread|http://forums.oracle.com/forums/message.jspa?messageID=3350877#3350877]. Among other things, it includes a function for determining if a given date (in any year) is a holiday, without reference to a table.

New infinity line and major speed issues with almo...

Hi,
Just has infinity installed after moving from my previous FTTC provider. With the previous provider i was getting 16 down / 1-2 up and it worked great.
Had my my new inifnity line put in on thrsday and i am getting 17 down / 0.5 up!!
I work from home and connect to the office via vpn and remote desktop and its almost unusable. Laggy, slow, unrepsonsive and is constantly dropping the connection with a failed to read from socket error and is making it very difficult to work form home effectively.
I have a 4g EE modem also and if i switch to this it is like lightening compared.
I also had absolutely no connection issues with my previous provider and as i posted above had a mich better uplink speed - which is where i think im getting most of my issues.
When i signed up to BT this is what i was sent via email:
We estimate your download speed will be 19.1Mb.
We estimate your upload speed will be 3.9Mb.
Im fine with the download but the uplink is shocking compared to the estimate - and as i had much better before i think something is amiss.
Also when i signed up i was told that if i had any connection issues with the new line i had to notify BT within 7 days and it woudl eb investingated but it seems there are so many roadblocks to creating support tickets etc.. Its like it s been hard to report a fault on purpose.
Where can i create a support ticket or similar to get this looked at?
Thanks

As you use the internet for work purposes did you have business broadband with your previous provider ?

Fresh install of Yosemite, nearly unusable, constant spinning wheel

Hello everyone,
MacBook Pro 13'', mid 2012
750GB HD
8GB Ram
2.9GHz dual-core Intel i7
A little background... once a year I usually back up my entire Macbook Pro, wipe it clean and install a fresh version of the most recent OS. I did this about a month ago and installed a fresh copy of Yosemite from Mountain Lion. For about 3 weeks it worked perfectly... running Adobe programs, and all my other normal applications (nothing big... Firefox, iMail, iTunes, etc).
NOW... about a week ago everything went to crap. The computer has become almost unusable without any change in habits of use. I get a CONSTANT spinning wheel whenever I click on anything its about a 30sec wait time and if I try to type something into Finder or Firefox its the death of the session... I have to restart the computer. Im at my whits end and about to use this computer as a expensive frisbee. This all started in Yosemite out of no where. There is NOTHING on my hard drive other than the operating system...
What I have already done:
Taken it into the Genius Bar. They ran some tests on the computer and physically took out the hard drive to test it on their systems. Everything checked out and received a PASS rating. They said it was nothing hardware related. They said it could have been a bad install of Yosemite since the hard drive was showing up as a "Logical Volume Group" instead of "Mac Extended Journaled". Suggested to go home and re-install Yosemite. So I did... 3 times... and nothing changed at all, same spinning wheel of death with nothing installed other than the OS.
In terminal
diskutil cs listdiskutil cs revert "UUID"
this changed nothing as well
Ran:
Verify Disk Permissions
Repair Disk Permissions - this fixed a handful of errors
Verify DiskThese 3 steps did not help much.
I am now back running Mountain Lion, it is more responsive but I still get a constant spinning wheel. Again, There is NOTHING on my hard drive other than the OS.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
The test works on OS X 10.7 ("Lion") and later. I don't recommend running it on older versions of OS X. It will do no harm, but it won't do much good either.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message. See, for example, this discussion.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
You may have started up in "safe" mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. If you don't know the password, or if you prefer not to enter it, just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, a series of lines will appear in the Terminal window like this:
[Process started]
        Part 1 of 8 done at … sec
        Part 8 of 8 done at … sec
        The test results are on the Clipboard.
        Please close this window.
[Process completed]
The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it and go to the next step. You'll have incomplete results, but still something.
12. When the test is complete, or if you stopped it because it was taking too long, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak for themselves, not for me. The test itself is harmless, but whatever else you're told to do may not be. For others who choose to run it, I don't recommend that you post the test results on this website unless I asked you to.

WRT400N Upload and Download Speeds

I have a WRT400N router. I have a network set up where I am physically connected to the router while my two room mates have a wireless connection. When I test my connection I have a download speed of 25 Mb/s and an upload of about 2 Mb/s. My room mates however have a download speed of .5 Mb/s and upload of about .5 Mb/s. They are getting full signal strength from my router, so I am not sure what the problem is. What is the problem and how do I fix this? They should be getting much faster upload and download speeds.

After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you have not done this since the last firmware upgrade, then please do this now and see if it corrects your problem. If you saved a router configuration file, DO NOT use it --- you must setup the router from scratch.
If the above does not correct your problem, then the most likely cause is simply a poor wireless connection. This can occur even if your computer shows "5 bars" or "full signal strength".
There are many causes for poor wireless connections, and many solutions:
First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
If your problem is that you are getting poor speed between your wireless n router and wireless n adapter, in the router, make sure the "Radio Band" is set to "Wide".
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4. For wireless n, make sure your standard and wide bands are at least 2 channels apart. For example try standard band on channel 11, and wide band channel 9.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna, if external, should be vertical.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. If your current network is not listed, enter its info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".
If the above does not fix your problem, download and install the latest driver for your computer's wireless adapter.
Some users have reported improved wireless performance by switching to WPA encryption.
If you continue to have problems, try the following:
For wireless n routers, try setting the "n Transmission Rate" to 162 Mbps, and the (wireless g) "Transmission Rate" to 54 Mbps.
If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
Hope this helps.

T430 Thermal Limit and Fan speed

Hello, I have a T430 with the i7-3520 and NVS 5400 1GB.
I'm a little concerned with the high temperatures my system shows. At idle and most of the time the temperature on the cpu is reported in the low/mid 40C range. (fan is very quiet or nearly silent)
However, I tried playing Age of Empires 3 to see how the laptop does. Performance was great, fan speed kicked up a little but I thought it was still VERY quiet (all my other laptops have much louder fans when they kick in). Initially I thought that was great, until after an extended play (1hr or so) I seem to have hit a thermal barrier of some sort. Frame rates droped massively, everything was choppy. Uppon exiting the game, I loaded HwMonitor and the cpu temp was reported to be 75C, nvidia temp 68C.
I read some other threads here, and I saw HIRO mention speedfan, so I installed that, but what puzzles me is neither software detect any fans, All I see is thermal sensors.
I did replace the HDD that came with the laptop with a Samsung 830 SSD. I used the Recovery disks to install the new O/S, so all drivers came through just fine.
Anyways, I like the fans being quiet, but once I'm over 50C or 55C I'd like this thing to start moving some serious dust. Is there a way to control their profile? The only option I saw was both in Bios and in Power Manager under "System Settings" there's an option "Optimize fan control to" and I have it set to Maximum Performance.
Thanks in advance,
-Phil

Hey PhilZJ,
Hey so Other people have an issue with speedfan not showing the fans and just temps you can use TPFancontrol if you want. On my T430 TPFancontrol shows temp of 53c and fan speed during start up but without pushing my temp past 55c the fan never kicks in or so TPF says being at RPMS stay at 0. Could I suggest you download TPFcontrol and run your game? See what temp and the RPMS your fan kicks up to? I would but playing games at work is frowned upon.
Best Regards,
Hiro
P.S. So if you set TPFancontrol to manual at setting 1 you get RPMS of 3434 RPMS, at 7 you get 5000+ RPMS.
Did you find a post Awesome? A response just Outstanding? Kudo them!
