probleme with broadcom 43142

Asked by mouad

Hi

I just bought a new notebook with the Wifi card Broadcom 43142 , and it not working good comparing with my old laptop with Broadcom 4313 .

I tested the last version of bcmwl-kernel-source and broadcom-sta installed via synaptic but it losing connection with the AP after some minute or not working after the connection .

I'm using the last version of ubuntu (16.04.1) , fedora and kali live cd don't detecting the Wifi and it is working very well in Win 10 from the some distance between the AP and the notebook .

Do you have and suggestion ?
