ThinkPad T420 - Crappy Wi-Fi Performance

#1 Post by atlacatl » Wed Nov 30, 2011 10:37 am

I bought a ThinkPad T420 about a month ago and I'm getting really bad Wi-Fi performance.

My card doesn't go higher than 24 Mpbs.

Is there anything that you guys recommend? Or did I go wrong with the site's default choice?

I just updated. It didn't seem to help.

http://forum.thinkpads.com/viewtopic.php?f=45&t=100180 contains info about connecting wifi through N routers. If you have an N router this might help.
