Hello all,
Im running Debian 9.1 and living connectivity issues with my notebook,my wireless chip is Broadcom BCM43142 802.11b/g/n
Im using Broadcom-STA driver and when i move to 5-8 meters away from modem connectivity issues (hard to connect to any site,slow speed) starts.

here is the result of the sudo modinfo wl

So im looking for solutions and i think i need to configure module options of "wl" (the STA driver) so what all those parm values,options mean ? how to enable/disable/change those options ? do anyone know them ?

thanks in advance.
