Thank you for this!

I had a Lenovo N21 Chromebook and the wifi card seemed to be faulty, but all it needed was a wipe off and It works perfectly now!

My Lenovo N21 was dropping the wifi connection. It did it a year ago and then improved, but the past month started doing it again very bad to the point I started looking for a replacement. It would maintain the connection for 5 minutes to 1 hour. I searched the problem, found this advise, and in 10 minutes it is fixed and has not dropped in 2 days. I assume it is fixed for good. Thanks for the tip and excellent instructions. Saved me $300 also.

Kerry Dalton - what did you do to fix your problem? Replace? B & W wires crossed?

Im getting ready to take this device apart.

I’ve replaced network cards in laptops before, so I’m not totally new at this, but from your diagram, my Lenovo 100e looks TOTALLY different. Has anyone had this issue? I can’t seem to find my network card. Or, is it integrated??
