I think you are confusing a WiFi module and a CPU…

T R - Mar 2, 2019

Sorry, incorrect. The cpu is on the mother board, not connected by slots. You may also notice the small brass connecteros on the left side of the wireless card. Those are u.fl connectors used for the wifi antennas. CPUs never ever have these

I need some help. My chromebook has a 2.4ghz processor but I want to upgrade it to a 5ghz. Is this what I should follow to do that? does it take an AC processor or only N? Will it be compatible if my processor is a broadcom and I want to upgrade to intel? Please let me know as soon as possible because my chroembook is really slow even though it comes with 32gb instead of 2gb.

Hi, also have the R11 bluetooth glitch. I’d like to try and preserve warranty as in the CI so can’t easily send it back for repair.

Is this likely to work with any microPCIe card or does it have to be the exact unit specified, believe there are 5 GHz variants now which weren’t available when originally launched.

Hey there! I could use some help. The WiFi won’t turn on. This happened on my C720 as well. Does that mean the wireless card is damaged or is it a loose connection? I’m not to savy at these things. Both Chromebooks worked until I started having the wifi issues. I tried to reset the C720, reload the OS, neither didn’t work and it’s been sitting on the shelf the past couple of years. although I just turned it on today, same issue with the OS.

I bought the R11 as a replacement and it worked fine up until last week. It doesn’t recognize wi-fi and it the wi-fi tab keeps defaulting back to the off position. Any ideas about how to approach this?
