I have recently installed Ubuntu for the first time ever on an old laptop and it went mostly well. A couple of days ago I dug out another old laptop and installed Ubuntu 16 LTS desktop (32 bit this time). Unfortunately this time connecting to wifi wont work. If I change location I can get in range of the 5 band which I can connect to without any problem. The difference in name between the two is the ' 5' at the end of the name (and the band of course).
I have looked around a bit for this problem but it seems like it is the other way around for everyone else. I also have a range extender for the 2.4 band that I can't connect to either. To rule out some conflict issue I checked that I have the same problem trying to connect to a wifi hotspot on my phone.
All these networks that I can't connect to work without any issue for the other Ubuntu laptop, as well as a windows 10 machine and a few android systems.
System log shows that it is an issue with timouts when trying to authenticate but editing the connections show that the right password is being used. All I get however is the trying to connect animation on the wireless symbol and then a message saying that I am disconnected.
While I am completely new at Linux I have done a bit of searching and tried a couple of things like network manager restart. I have also checked that my hardware is properly supported (it was the very top device listed under Intel).
Does anyone have any clue why one band is working while I can't authenticate on the other?
