Connected to network, but that's about it

Post by cardant »

So, currently the nm-applet shows that I am connected to my network. I see that I have a valid IP address, and if I run an arp-scan from my laptop, I can see the IP address assigned to my desktop on the network. However, if I try to ping anything (internal IP addresses like my laptop, URLs, broadcast IP, etc.) from my desktop I get 100% packet loss. The same thing happens if I attempt to ping my desktop's IP from another computer, such as my laptop. Both my laptop (which is running fine) and desktop are running Mint 17.2, and my desktop also has Windows 10 installed (Also working fine). My desktop's wireless card is an ASUS PCE-N15, and I know that I have the correct driver, RTL8192CE, installed. While I was home for the summer, I was using my desktop with no issues (excluding slow connection speed), but when I moved into my apartment for college it started acting up. I have basically no control over our network (they have the settings web page under lock and key), so it rules out a lot of troubleshooting options for me.
Here is the output of ".usr/lib.linuxmint/mintWifi/mintWifi.py" on my desktop:

I have tried a handful of things, like switching to static IP, switching to another DNS (google), but nothing has changed.
Any help would be greatly appreciated!
