Wifi stops working following inactivity or suspend.

Post by ambrostan »

I have LMDE 2 Betsy installed on a Lenovo G70-70. The Wifi card is a Broadcomm BCM43142. It connects wirelessly to a TP Link Archer AX3200 router. It works flawlessly until I leave it inactive or close the lid of the laptop (which is set to suspend). When I then try and use the computer wireless has disconnected sees no networks at all.

The only way to get it to work again is a re-boot.

I have other devices connected to the same router with different OS/hardware that do not suffer from this issue.

I have read all of the information on this forum regarding similar situations with different hardware/software but cannot seem to figure it out.

Sounds like power management may be turning the card off, in which case there should be a setting to disable this. I don't use LMDE myself so hopefully someone who does will be able to offer better advice.

Does sudo service network-manager restart bring it back?

My router is a TP-Link Archer AC3200 tri-band router.

Not sure if this is solvable but, being used to Linux working out of the box with no glitches, the problem solving is a new thing for me.

I have used different versions of Mint over the years with very few issues, this issues seems to have just appeared.

Any help would be very much appreciated.
