Whenever I refresh my server browser list, and or try to connect to a server, it causes my internet to become extremely slow until it finally just disconnects. I get disconnected from steam, skype, and can’t even sign into Xbox-Live. The moment I quit Gmod, everything comes back online and starts working again.
However, I don’t have this issue when I try and play TF2, DoD:Source, CSS, or CS:GO.
I’ve tried to re-install it, defrag cache, and verify integrity of game cache, but nothing works.
I think its also important to mention that about three months ago we upgraded our internet from DSL to a Fiber Optic connection, but we never upgraded our router which is http://www.netgear.com/home/products/wirelessrouters/simplesharing/WPN824N.aspx
Is this a problem with Gmod, or on my side?
