Cannot connect to some wifi networks.

Owen Thomas
Hello people.

I was just wondering if anyone has had any issues connecting to some wifi networks since last updating Ubuntu 16.04. If you think you can help, please let me know what information will help you out, and I'll supply it.

Thanks,

  Owen.

Perhaps if you gave more details it would help.  What do you see in
/var/log/syslog when you try to connect?

Thanks Colin for letting me know where to look.

I'll get back to you in a day or so after I've been in a location where I'm experiencing connection problems.

Rghto...

I start the System Log viewer, attempt to connect to the wifi I am having trouble connecting to, and see the following output appear in boldface in the system log:

Have you tried removing the connection (from network manager) and
reconnecting?  You will have to enter the password again.

Re: Cannot connect to some wifi networks.

Owen Thomas
Another person started having similar trouble to me. They turned the wifi off and then on; it didn't work. They called their internet provider, and the provider told them to turn the wifi off, wait for 30 seconds, and turn it back on. That cleared the problem for them and me.

Is that the wifi on the PC or the router that you turned off/on?  If on the PC then I would have expected a reboot to have fixed it.

Re: Cannot connect to some wifi networks.

It was the router. I rebooted my PC multiple times before I came here.

Thanks anyway for your offer of help Colin; it indeed appeared merely to be gremlins in a FRED.

That does seem odd. You said the problem started when you upgraded Ubuntu, so the requirement to switch off and on wifi at the router seems unusual.

Re: Cannot connect to some wifi networks.

Owen Thomas
My update of Ubuntu and my loss of access to a router appears merely coincidental. I only suspected that the problem was because of an update. I didn't know where the problem was coming from, and, because my computer appeared to be the only one using the router to have the problem, I (erroneously in hindsight) speculated that the problem was due to an Ubuntu update that happened meanwhile. As most things seem to sort themselves out in this way, I wasn't surprised to find my suspicions came to naught although I am happy to find that I have access to the router again.
