[ubuntu] Wireless working but no list of networks

Hi,
I have being using Ubuntu Mate 16.4 for about 3 weeks. Pretty awesome.
The problem I have is that my wireless coection works just fine, but if I want to switch to another wireless coection, no other networks show up and there's about 4-5 networks. I have to reboot in order to see all the list of wireless networks around me. It's pretty weird.

Must solutions I found on the Inteet is with people with no wireless coection working at all, but that's not the issue I have. It coects just fine when I boot, but after a while I can't see the other networks so I can coect. It's pretty aoying I have to say.

Any help is appreciated
