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?

    Which Wi-Fi chipset do you have? – Android Dev Jul 30 '18 at 23:35
  • Note that Ubuntu 16 doesn't exist. You mean 16.04. The version number represents 2016.April. – wjandrea Jul 31 '18 at 0:43
  • @Android Dev. The hardware is PRO/Wireless 3945 ABG (Golan) from Intel. – NacMacFeegle Jul 31 '18 at 9:38
  • @wjandrea I know it was a bit shorthand, but I was on my mobile in the middle of the night and got a bit uncertain of the exact number. I did not know about how the versions where assigned so thanks for mentioning that. – NacMacFeegle Jul 31 '18 at 9:38
  • Are the problem access points using wireless N mode only? – Jeremy31 Jul 31 '18 at 11:29
