[kubuntu] A weird DNS issue

Hello all,

I'm facing a rather quaint inteet issue, which I think is a DNS issue. I'll narrate the problem, but I'm not very proficient with behind the scenes operations, so I request you to bear with me.

I'm using Kubuntu 15.10 on my laptop (Plasma 5.4.2). I'm on a university network. I'm able to access inteet fine from my dorm room, where I've hooked up a wireless router to the university network etheet port, but not anywhere else on campus - all on the same campus local network - regardless of whether I coect using a wireless or wired network. The issue persists even when I plug in the same cable from my wifi router to my laptop.

When I access through my wireless router, everything is fine - I can access all websites. When I access from elsewhere on campus, the coection is established, I get assigned an IP, the DNS addresses are given with the DHCP leash, and pinging IP addresses work, but pinging hostnames or trying to access a website through a browser does not work. For example, pinging 8.8.8.8 works, but pinging google.com times out. Accessing my university website IP address - hosted on the intranet - works, but not if I use the hostname. Accessing one of the google IPs through a website redirects me to google.com and times out. I put in the IP address of stackexchange, and I get at least a stackexchange error page (thus hinting that if I give IP addresses of websites, the coection goes through, but not if I give the hostnames). I tried manually configuring DNS addresses (given by campus network support, and the same ones which my laptop and other computers seem to coect to when plugged in via etheet) using Network Manager, but the results were the same.

What makes it so weird is that everything works when I coect via my wireless router. I think it's a problem with my installation because I booted from an elementary OS usb stick, and everything worked fine when I coected outside of my router - I could access all websites using hostnames.

Here are outputs from "nmcli dev show" for various instances-

From Kubuntu, coecting through my wireless router (everything works) - http://paste.ubuntu.com/15703658/
From elementary OS, coecting through etheet (everything works) - http://paste.ubuntu.com/15703670/
From Kubuntu, coecting through etheet (problem listed above - caot access hostnames, can ping ips) - http://paste.ubuntu.com/15703678/
(the results are similar to the last, no matter where else I coect on campus)

This is info from my wireless router-
Coection Type Dynamic
WAN IP 10.8.16.173
Subnet Mask 255.255.254.0
Default Gateway 10.8.16.1
DNS Address 10.1.2.61

I spent a lot of time with my campus network support, but they weren't able to figure it out. They did check and guarantee that there were no blocks in place, and that the network does not discriminate against Linux or any OSes. I have installed Kubuntu 15.10 on a friend's laptop and another friend's PC, and both those installations are working fine coecting directly to etheet ports on the campus network.

I did do an initial search, and as suggested here, commented out "dns=dnsmasq" in /etc/NetworkManager/NetworkManager.conf . Did not help, results were the same.

Any help would be very much appreciated! Thank you for your time and patience.
