Wifi occasionally drop in WPA2 Enterprise network #11

yodahuang commented 7 years ago

I have both 4.12 and 4.13 series of kernels installed on my Surface Book. Wifi is good in the normal home environment. But it's not so good in my university, where the following configuration is used:

Wireless security: WPA2 Enterprise
Authentication: Protected EAP (PEAP)
CA certificate: AddTrust External CA Root
PEAP Version: Automatic or Version 0
Inner/Phase 2 authentication: MSCHAPv2

After booting, the Wifi cannot be automatically connected, manually connect does work, but after like 10 minutes it would drop the connection and you're not able to reconnect again.

Yeah I suffer from this issue and have resigned to the fact that the roaming function required for enterprise networks is too perplexing for this network driver. Have pretty much tried everything but the only solution seems to be to go back to linux 4.9 with the old wifi patch which ends up being shockingly stable

same problem here.

jakeday commented 6 years ago

I fixed as many of the WiFi issues as I could in my 4.14.x series kernel, and this is one of them. Should be working now and I have verified it does.

yodahuang commented 6 years ago

I tried your 4.14.RC5 in Ubuntu, however, the normal Wifi or LAN connection does not work now.

jakeday commented 6 years ago

Did you remember to apply the apparmor patch file mentioned in the instructions?

yodahuang commented 6 years ago

Oh sorry, After applying that works. BTW, in the README there's a typo chmow which should be chmod, and when do dpkg install, header should be in the front of image. Thanks for your work!
