My Wi-Fi card seems to like dropping 5% to 10% of its packets on pingtest.net as well as ping in cmd, which reports "general failure". While I can still browse websites, anything requiring a stable connection like Skype or gaming drops all the time. The packet loss stays pretty consistent regardless of how far I am from the router and what router it is. The interesting thing though is that I can ping just fine using a Ubuntu LiveCD through the terminal (although I was unable to verify with pingtest.net because I couldn't get Java working properly). Something therefore seems messed up with Windows and this Wi-Fi card. Reformatting didn't resolve it, driver updates didn't resolve it, installing Access Connections didn't resolve it, playing with the driver settings didn't seem to do anything, and Google's been generally unhelpful on the subject. I'm pretty sure I have an Atheros 802.11g card. Is there some known solution to this or does Windows 7 just hate this card?

Did you try changing your windows 7 power settings?

Control panel, power options, change plan settings in your power plan, change advanced power settings, wireless adapter settings, power saving mode, make sure both are on maximum performance.

Then in device manager, click on your wireless adapter, advanced, make sure roaming aggresiveness is medium and throughout enhancement is enabled, and transmit power is highest.


If you're using Lenovo's power manager, you'll have to change the power settings in there also.

I've already set power settings to maximum performance with no effect.

Try another card.
I've successfully used the Intel Advanced 6200-N in several T60 and X60 machines.
This is a half-size (of your current) MiniPCIe card which also requires a bracket to make it fit.

I unfortunately don't have another card to test with, but seeing as it works under Ubuntu it seems like there must be some way to resolve it under Windows.
