broadcom wifi BCM43142 lag problems

Post#1 by mrlovaxrovax » 16 May 2017, 22:56

Hello,

I've read as many forum posts on the broadcom issues as I can but I've not found a solution. I've just installed Porteus3.2.2 on my laptop and although wifi is working, it can take a long time to connect and there is often a lag when connecting to websites or downloading pages. I believe this is related to Porteus as the same laptop has Windows 10 installed and the Wifi is fine - also other devices in the house don't have this problem; the wifi is definitely much worse under proteus where it can take a minute to download a simple page. I've got the following card/chipset:

root@porteus:/home/guest# lspci -nn -d 14e4:
02:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)

I tried blacklisting wl and unblacklisting all the other drivers. I did this by adding a blacklist wl line to both b43_blacklist.conf and broadcom_blacklist.conf and uncommenting all the other drivers (maybe this was wrong...) After a reboot I didn't have any wifi functionality at all, so I undid this change. Any help much appreciated.

Regards,

Simon
