T400 vista home basic WiFi Link 5300 Disconnecting

2008-10-24, 22:52 PM

Recently received a new T400, vista home basic ,Intel WiFi Link 5300 (AGN) (part number 42X6325  )

After sever hours of usage the wireless network stops working- and cannot find any wireless networks at all .

Restart of the computer solves the problem- it easily finds 7-8 of the active networks in the area and connects to the one at home for several hours until the next time it stops working..

Any suggestions (drivers, windows options (never used Vista before))  are very welcomed.

 

Mark.

I have the same problem. And when I download large files the machine "hangs" for periods.

 

Mark, it helped a bit to register the location on the Access Connections, input wlan security settings there to and activate it via the Access Connections. This way helped me a bit. But not 100%

I been thinking about getting the T 500 before the sales expires on nov. 3 08 but im so glad i came across this problem about the internet connection. There's no way anyone of you have a lenovo technician to come out and fix the problems. sorry i dont know if thats possible. Does anyone have the same problem with the ThinkPad 11b/g Wireless LAN Mini PCI Express Adapter III   ??? its the cheapest one they got on the t500... im curentty using a mac book pro and it works fine  with the internet connection and i dont know if they use the same kind?....    I was wondering if its worth getting? and if the internet problems will be fixed..

How could lenovo sell a laptops that does not work  fully.

ThinkPad Intel WiFi 5300 Wireless Connection Drop Problem and Solution!

2008-12-09, 14:51 PM
ThinkPad Intel WiFi 5300 Wireless Connection Drop Problem and Solution!!!

I have read about Intel WiFi Link 5300 wireless connection drop problems on many different forums, including ThinkPads and many on other computer systems.  In the end, I was able to solve this problem using a simple approach documented below in the SOLUTION DESCRIPTION section.


************
PROBLEM DESCRIPTION:

- Wireless connectivity works but drops connection after a few minutes, sometimes as quickly as just a few minutes, other times taking as long as 30+ minutes.

- The ability to replicate the problem is consistent, in that it always stops working in a relatively short period of time.  However, it is impossible to predict how long before the connection drops, although it usually happens in less than 30 minutes, sometimes even quicker.

I received a W700 2 weeks ago, loaded with Windows XP Professional and the Intel WiFi Link 5300, etc.

This connection drop problem happened to me while running Win XP SP2 as well as SP3.

Note: I've heard that SP3 vs. SP2 matters and I've read some forum entries that indicate rolling back to SP2 fixes the problem.  However, I've seen other evidence/posts that indicate it doesn't make a difference.  Regardless, I am running Win XP Professional SP3.

I tried updating to the latest Intel 5300 driver (12.1.2.1) alone and the problem did not go away.


I also tried updating multiple drivers via the Lenovo site.

The latest Intel WiFi Link 5300/5100 drivers available on the Intel website are newer than those found on the Lenovo support and download site.

In the end, a posting on several forums by jposner led me down the right path, which was to update my ThinkPad with three things: (1) Intel WiFi Link 5300 driver (2) Intel WiFi Link PROSet software  (3) Latest ThinkVantage Access Connections

The specifics of these three parts of the solution are described below in the "SOLUTION DESCRIPTION" section.


************
SOLUTION DESCRIPTION:

1) Update Intel® PRO/Wireless and WiFi Link 5300/5100 Drivers-Only (12.1.2.1)

AND

2) Update Intel® PROSet/Wireless WiFi Connection Utility (12.1.2.0)

using one of the following links:

http://support.intel.com/support/wireless/wlan/5300_5100/index.htm
(Multiple downloads for different Operating Systems)

http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=3062&OSFullName=Windows*+XP+Professional&lang=eng&strOSs=44&submit=Go!
(XP Specific)

http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=3062&OSFullName=Windows
(XP 32/64 & Vista 32/64)

3) Update ThinkVantage Access Connections V5.0.2

   Use Lenovo Downloads and Drivers for your model ThinkPad, via the following link:

   http://www-307.ibm.com/pc/support/site.wss/homeLenovo.do


The combination of ALL three of these has fixed my wireless connection drop problem, which would happen anywhere from 3 minutes to 30+ minutes after an initial wireless connection.  I have run for days now without a wireless connection drop, across 802.11a/b/g connections.


***********
POTENTIALLY IMPORTANT ADDITIONAL DETAILS:

I also found it useful to configure the Intel WiFi 5300 Wireless Driver with the following details:
(This is based on reading many other posts across many internet Wireless 5300 & ThinkPad forums)

o Power Management "Highest" and Roaming Aggressiveness "Lowest"
  
  Start > Settings > Control Panel > Administrative Tools >  Computer Management > Device Manager >  Intel WiFi Link 5300 AGN Properties > Advanced Tab

    o Power Management "Highest"

    o Roaming Aggressiveness "Lowest"

o Power Saver mode off (don't let Thinkpad/Windows Power Management turn wireless off to save power)

  Start > Settings > Control Panel > Administrative Tools >  Computer Management > Device Manager >  Intel WiFi Link 5300 AGN Properties > Power Management Tab

    o Un-Check "Allow the computer to turn off this device to save power"

o ThinkVantage Access Connections > Manage > Edit Profile for your connection > "Wireless Settings" Tab

    o 5. Advanced Configuration "Settings" button > "Power save mode:" >  "Low (best network performance)"


Please feel free to comment here or email me with questions. 

P.S. I am extremely happy and impressed with my ThinkPad W700 > It is FAAAAST, awesome display, great drive bays, and much much more...
         This W700 system totally ROCKS!!! (especially now that my WiFi is rock solid:-)
