Thinkpads Forum

Hi,

I Had this problem with wireless no longer working after suspend or hibernate:

The problem was solved by the instructions for power settings at this link, but the page is no longer there.

Does anyone still have the actual pdf that was there or perhaps an alternative set of the same instructions.

Thanks.

if you want to change power management for your wifi adapter, do this;

Run > devmgmt.msc > expand Network Adapters > right-click your wifi adapter and select "Properties" > Power Management tab > uncheck "Allow the computer to turn off this device to save power."

I've got it.

a friend and myself have the same problems with our thinpads, his a T61, mine an x60 tablet, both of our wifi cards drop connectop after a period of inactivity, and won't connect unless rebooted.
I've already unchecked the box that allows the computer to turn off the device in power saving mode, but it still drops connection regardless, and I end up having to reboot each time

is there another step?

AFAIK this problem existed with older intel wireless drivers. I experienced the same behaviour in XP and Vista. But since upgrading to the latest intel drivers from Lenovo i never had this problem again and DPD is enabled on my TP.

I have the same problem when resuming from hibernation. I've used the wireless adapter settings as recommended above, but I have the Intel 82566 network adapter, which does not have a setting that the one above does.

This is getting tiresome having to "repair" the wireless connection repeatedly.

I had the same problem for a couple of months after I bought my T60 8744-5BU in May '07. Here's the first thing I found that helped:

Open ThinkVantage Access Connections, > "locations", >"manage profiles", (highlight a profile) > "edit", General settings: UNCHECK
"disable this wireless radio when changing locations". Do this for each of your profiles. This initially helped somewhat, but the problem still happened now and then.

The final cure was downloading and installing the latest drivers for my wireless card from the Lenovo "downloads and drivers" page. Make sure you enter your TP model # or let the site detect it. The clincher was that the "summary of changes" described the problem fixed to a "t"! My wireless has been problem-free since.

BTW: I am not a big fan of the ThinkVantage update software and package server. I use the software to detect updates available, but prefer to go to the "downloads and drivers" page to get more information on the updates and then download and install one at a time only what I want.
