Can't connect to wifi or ethernet on campus
When I was at home, my T420 had no issues connecting to the internet using ethernet or wifi. When I got on campus, however, I was unable to connect to the wifi. Wifish would seem to connect just fine, but when trying to connect to the internet I would be unable to do so. If anyone has any potential ideas for what could cause this, I would be grateful.

Running W10?
Try a Life-Linux CD to check if you can connect with that.

Re: Can't connect to wifi or ethernet on campus
Does your campus have that WiFi that requires a username and password to login because my X61s was having much trouble getting in and a little bit of trouble on my T520.Catanatron wrote: ↑Sun Jan 27, 2019 11:39 pmWhen I was at home, my T420 had no issues connecting to the internet using ethernet or wifi.

Sorry, I'm running Void Linux. I could still give it a try to see what happens.RealBlackStuff wrote: ↑Mon Jan 28, 2019 7:13 amRunning W10?

Re: Can't connect to wifi or ethernet on campus
Well I don't exactly remember...I might have just tried it a few times. The X61s was running Mint when it was having trouble. Switched to Ubuntu and the problem was solved. T520 was on 7 and I think I just "brute forced" it. It might have something to do with that stupid authentication and bad WiFi drivers. Try updating them.

Re: Can't connect to wifi or ethernet on campus
It also depends on the authentication method. Make sure you are selecting the right kind as you connect.

Re: Can't connect to wifi or ethernet on campus
Wifish seems to handle that on its own. Either way, even ethernet doesn't seem to work, and I don't have to select anything for that.MrBurgerKing wrote: ↑Mon Jan 28, 2019 2:33 pmIt also depends on the authentication method. Make sure you are selecting the right kind as you connect.

Re: Can't connect to wifi or ethernet on campus
On ethernet, are you assigned an ip address from the DHCP server? Can you communicate with other devices on the network? Does your school have authentication over ethernet by chance? Maybe a login portal? If there is, are you using the local DNS or did you set yours manually? Do other laptops work just fine and it's just yours that has this issue? Does your university have any support documents related to this issue? Are there any special steps they want you to take to connect?Catanatron wrote: ↑Mon Jan 28, 2019 4:07 pmWifish seems to handle that on its own.

Re: Can't connect to wifi or ethernet on campus
I'm not sure about the first one or how I'd check that, I don't think so, ethernet has no authentication or login portal, I did not set my dns manually, my other laptop works fine, afaik there is no additional documents on connecting.MrBurgerKing wrote: ↑Mon Jan 28, 2019 4:59 pmOn ethernet, are you assigned an ip address from the DHCP server?

Re: Can't connect to wifi or ethernet on campus
On windows, open command and type
On linux, open terminal and type
If the network interface shows a valid address, first ping the gateway by opening a terminal and typing ping, then leave a space, then the gateway's address.
If that works, try pinging a website like www.google.com
If it doesn't, there is a problem with your configuration. Linux can sometimes be really picky about what drivers and utilities it will and won't work with.
For wifi, wifish does not support WPA2-Enterprise. Use a different tool.
Consider posting in the linux section of these forums. You may also want to use Windows since that's what the school's network and your laptop were designed for.
Code: Select all
ipconfig
Code: Select all
ip a
If that works, try pinging a website like www.google.com

Re: Can't connect to wifi or ethernet on campus
Did you check that the wifi switch on the right side is ON? And is it working?
Tried Fn/F5 under Windows?

Re: Can't connect to wifi or ethernet on campus
Sorry for the double post. I tried using a Manjaro Live CD and upon trying to connect to ethernet it says:
"Error checking authorization
failure creating GDBusProxy for authorization request"
I hope this is meaningful to someone. Thanks for the help.

Re: Can't connect to wifi or ethernet on campus
It is possible that ethernet connection requires you to be registered somewhere and, until that happens, you won't be assigned the ip. Who's the ISP on that campus? Are you able to compare with friends who use ethernet?
About wifi, what exactly is the authentication method used by the network (WPA, WEP, eduroam, etc...) ? Which network manager do you use?
