the 6205 wireless card on my x220t cant hold a singal. tried on multiple wireless networks and redownloaded drivers. my old macbook doesnt have problems at all and im being forced to use it to post this.
anyone else having horrible connection problems with the 6205 wireless on the x220t?
also whenever the connection drops it switches focus to the taskbar (even with all icons/notifications disabled) and minimizes any windows i have opened full screen
any advice would be greatly appreciated.

Windows 7, I hope.
You might try tweaking your power settings. If you're using Lenovo's power manager bring up the power manager and in advanced settings, wireless adapter settings make sure it's set for maximum performance in battery and ac settings.
Then in windows, control panel, power options, in your plan, click change plan settings, click change advanced power settings, wireless adapter settings, power saving mode, make sure they are both set to maximum performance.
One more, In device manager, click your wireless adapter, properties, advanced, make sure roaming aggressiveness is set to medium, throughout enhancement is enabled and transmit power is at highest.
See if any of this helps.

thank you both for the responses!!
i gave all that a whirl ...
i changed the power setting from max battery to max power in the thinkpad options and set everything else i could up to the highest level elsewhere in terms of battery, not turning off signal, etc.. i tried uninstalling the drivers and restarted letting windows do its own thing. did a manual install of the latest drivers and found an older set so i tried those as well. tried changing the ordering of the adapater / controller in the setting just because it was something else i could click that seems relevant
i also feel like singal is coming in weak. getting 80% singal quite often while sitting 4 feet from my wireless router.

Is it any better on other wireless networks? Maybe try changing your encription on your router. If it works on other wireless networks maybe see if there's new firmware for your router. There's another thread here somewhere about changing the setting on the router from 20hz to 40hz. Maybe see if there's a setting in there and see what it's set for.

Dave, thanks for the response. I had tried this out on 4 differet wireless networks. - 1 at home and 3 at work. Getting the same result across all.
I haven't tried changing the encryption method on the network yet, but if i'm able to get a solid connection on other laptops this shouldnt be the cause of the problem.
As of right now i'm having better luck with the older set of drivers (manually installed). its still not performing the way it should, but its not dropping every 30 seconds anymore ... now i only lose connection every 5 minutes which is bad, but MUCH more tolerable.
The only thing that bothers me about my current setup (besides the ongoing loss of signal) is I have every possible setting put to maximum power so my battery life, on average, is an hour less with these settings in place.
I'll continue tweaking this to see if I can figure out a better way. I've yet to try a clean install as I don't have a windows CD to boot from.
Thanks again to everyone for the responses!!!!

I figured your battery life would take a dump. How about going to the intel site and running their update scanner and see if it comes up with a different driver for your wireless.
I just didn't want to blame it on some obscure power setting, that's why I said to tweak everything to max. I do know that some of these new wireless cards don't seem to play well with some routers. Any way to test it on a public network, or is that what's at work?
