Lenovo X61T Updating Wireless drivers changes mode, G to B

d3fcon · 03-18-2009, 08:36 PM

Hi,

I just updated my wireless drivers to 7.6.0.96f, and I enter device manager, click the Advanced tab, and I see 802.11b Preamble, Wireless Mode Selection has 3 options: Auto, 2.4GHz & 4GHz.

I had to switch my router to 'Mixed' mode for me to be able to connect to the internet, I previously had it set to Wireless G only, which worked with the older drivers.

The older driver is the one that Windows finds as the latest update (through device manager), which is 7.3.1.42, it still says 802.11b preamble and wireless mode selections are the same as above. BUT I can connect to the Wireless G only connection (just changed it on my router).

I understand some might think that I shouldn't even bother updating since it works, well the reason I need to update to newer drivers is because I have been experiencing quite a bit of BSOD's related to the network adapter (hardware or software), whenever I leave firefox running in the background for a extended duration, it seems to BSOD out of the blue. And when I'm in class I turn off my wireless to save battery, when I'm using MS Office OneNote and I flick wireless off, it sometimes BSOD's (happened today).

I have a:

- 11a/b/g Wireless LAN Mini PCI Express Adapter

- X61 Tablet (7764-CTO)

- Access connections not installed (don't need it)

Thanks!

Try this one instead, from IBM website

Not as 'new' as what you have recently installed but newer than what you had then.

Sorry, forgot to mention I'm running Windows Vista SP1 Business.

The 7.4.2.134 says it's for Win XP/2000, would you recommend installing it anyways?

**TriggerFinger** · 03-18-2009, 10:40 PM

Ooops... my bad.. try this one:
http://www-307.ibm.com/pc/support/si...cid=MIGR-67351

Same as yours but Rev. 01 as per http://download.lenovo.com/ibmdl/pub...s/7ywv11ww.txt

Installed it, and the same things happening.

-Windows detects the wireless signals in the area, but cannot connect to them. My own wireless signal is 100% and when I diagnose the problem, it says I need a stronger signal.
-Router is on 'Wireless-G only' mode, cannot connect to the router or internet.
-Router is on 'Mixed' mode, connected to the router and able to access the internet.

Open Device Manager, get properties of WLAN, select Advanced tab. Check if you can set Wireless Mode property to mixed/B only/G only.

Please also post DEVICE INSTANCE ID of this Wireless card (Device Manager, properties, details tab).

Under the Advanced Tab, I select wireless mode selection, there are 3 options: Auto, 2.4GHz Only & 5GHz Only.

When router is set to 'Mixed' mode
-Selecting 'Auto' and '2.4 GHz Only' allow me to connect to the router and the internet.
-5 GHz, I believe is for N, does not work

When router is set to 'Wireless-G Only' mode
-Unable to connect with auto, 2.4GHz or 5GHz

Device Instance ID isn't listed in the drop down box, closet match to that is Device Instance Pathway, which is: PCI\VEN_168C&DEV_1014&SUBSYS_058A1014&REV_01\4&20C2E43&0&00E1

Don't know if that's it

I'm gonna head off to bed, so I'll respond a bit later. Thanks for the help so far!

I was expecting you will see something like:

Code:

wModeSelect                  = "Wireless Mode"
wModeSelect11bonly           = "11b only"
wModeSelect11nbg             = "11n(2.4GHz) and g and b"
wModeSelect11na              = "11n(5GHz) and a"
wModeSelect11abgn            = "11abgn"
wModeLegacy11a               = "11a only"
wModeLegacy11bonly           = "11b only"
wModeLegacy11bg              = "11g and 11b"
wModeLegacy11abg             = "11abg"

When router is set to 'Mixed' mode
-Selecting 'Auto' and '2.4 GHz Only' allow me to connect to the router and the internet.
-5 GHz, I believe is for N, does not work

yeah I don't see that long list, I go to device manager, right click my wireless adapter, select properties, go to the advanced tab, click on wireless mode selection and I'm given 3 choices: auto, 2.4GHz only, 5GHz only

May this can help:

See attached zip file.

d3fcon · 03-19-2009, 09:36 AM

Where do I place these files?

**TriggerFinger** · 03-19-2009, 11:14 AM

Extract them in a folder (ex. Atheros folder). To install you have to do a manual install of the driver via the Device Manager or you can use this guide (scroll down until you see LOCAL):

K, it installed 7.6.0.154. Under the Advanced tab in the adapters properties, and under wireless mode selection, it still lists: auto, 2.4GHz and 5GHz.

As for setting my router to wireless G only, or mixed, I cannot test that at the moment, I'm on my campus wireless network (which I'm almost certain is set to mixed).

I'll test my router when I'm back home, but for now, I can connect to my campus internet with the 7.6.0.154 drivers.

**TriggerFinger** · 03-19-2009, 01:04 PM

Ok then... just keep us posted.

Thanks.

d3fcon · 03-19-2009, 08:26 PM

Back home and set the router to wireless-G only, and the same problem occurs. I cannot connect to the router or internet, unless I change it back to mixed mode.

But, on the other hand I haven't experienced any BSOD's yet.

**TriggerFinger** · 03-19-2009, 08:48 PM

Just an idea if ever... reinstall the old driver and wait until you get BSOD. I am thinking that the BSOD before was not caused by the driver but may be something else.

Another is if you are using any encryption (ex. WEP,WPA, etc.), disable that first.

And I know you may not like this but install the Thinkpad Access Connection utility. May be it can do wonders.
