Hi...i am also having the issue. I've disabled power saving mode for the LAN port but unfortunately, it did not solve the problem. Can you provide a link to the long forum post that you have mentioned in your reply? Any other help is most welcome. It has really become frustrating for me. Another point is that my laptop is not an old one. To be accurate, it is 1yr, 3months old. Is there any way to check if the hardware itself got damaged because I've almost exhausted all the other options. turnkey pcb assembly
I’ve been trying to get to the bottom of this as well. I’m using a Wintel W8 which uses a BCM4356 Broadcom wireless interface. I’ve tried the approach of installing firmware-b43-installer and bcmwl-kernel-source with no luck. Has anyone had luck with getting Broadcom interfaces to work?
