No internet on wifi after some hours - remove/add module to fix

ali_molaei · 2017-01-01 08:40:39

I have a strange problem with my wifi connection

If I leave laptop connected to my home wifi for about 2 or 3 hours without activity, when I come back, it is connected to wifi but i dont have internet, even disconnecting and reconnecting to wifi is not solving the problem

The stranger thing is that if I connect to another wifi, then I have internet, and then if I connect to my wifi again I have no Internet

The only solution I found is:

sudo modprobe -r wl
sudo modprobe wl
sudo systemctl restart connman.service

This is really annoying me. and I don't know what to do.

How are you managing your network connections? Is it NetworkManager or systemd or something else? Start with the log files for whatever manager you're using. Also, can you be more specific about what is not working? Are you able to resolve domain names through DNS? Can you ping other machines on the LAN?

I guess this is broadcom wireless card, with poor support. If your card is supported try changing to brcm** (kernel driver)
@Rob_H he is using connman for managing network

My laptop is using Broadcom Limited BCM43142 and yes it's driver is not opensource.
I was using broadcom-wl-dkms and last night I replaced it by broadcom-wl but the problem is still persist...

What can I use to change brcm** (kernel driver)?

I'm using Connman

Thanks for your reply but i read this page 3 times and before asking here searched a lot as I saied only broadcom-wl and broadcom-wl-dkms are working for me and I have problem with them.

I hope you explain more instead of just leave a Link and go

Docbroke · 2017-01-03 07:51:54

I searched for you, and it appears that bcm43142 is only supported by wl driver. So you are stuck with it.
I would suggest that you use dkms varient to avoid manual recompiling on every kernel update. I don't think we can do much here.

I'm now using a D-LINK external wifi modem and the problem is gone, so my laptop wifi problem was from driver as you said... thank you. hope broadcom give us a free driver
