If I try to change repositories however, I get "unreachable" in all of them. If I try to update the cache I get this:

So I thought I would try to see if my router had some weird settings, and what I found out is I wasn't able to access it. So I installed a VPN chromium extension and voilà. I also noted that some sites, like my ISPs website, were not accessible:

So I reset the settings. Once the connection came back up the first few times I tried opening a website I got "Resolving host in proxy script" in the browsers status bar. Weird again. After disconnecting the ethernet cable and reconnecting it started working fine, and I was able to access my router and other websites that didn't work previously.
The repositories were still not reachable (and I can't use VPN to access them as I used a browser extension), so I did the "Fix MergeList Problems" solution and "sudo apt-get clean" to no avail. I also tried to unset http_proxy and ftp_proxy to no avail.
I suspect this extension may have changed something because when I disable it I can't access any repository URLs, but when I enable I can, however I don't know what could it be doing to the system that may be affecting everything else. I tested with my smartphone and it can access everything just fine.

I'm currently trying sudo apt-get update but it's taking ages. I also tried to access my router from Firefox and got the same problem. What could it be?
