Ubuntu can't detect wifi, even after reinstalling the driver (BCM43142)

Question

Recently after fiddling a bit with routers in my apartment I discovered that ubuntu can't detect my own home network anymore. It had no problems doing it for last 6 months.

What I already did:

sudo apt-get purge bcmwl-kernel-source
sudo apt-get install bcmwl-kernel-source

Weird events before that happened include:

retrying connection to my home wifi even after trying to connect to other one (it stopped after reboot),
long connect-in-progress times,
denying to connect to perfectly good network, even though my other pc did it with no problem.

If someone could suggest me what can I do now I would be very grateful.

@edit: Done what comments said :).

I repaired it setting my WiFi fixed on channel 7, now ubuntu detects it with ease again. It Was auto-set on channel 11. I'm curious why BCM can't detect it on channels higher than 10.
