Log in and no servers display

[Zippit]

SO after trial and errors I had the brilliant idea to Hotspot my Mobile Phone and connect to that wireless connection on my pc. and............whatdoyaknow! Servers show.

Question is, why isnt it working on my home wireless network.

Charter/Spectrum
Technicolor DPC3216 Modem (Yay for Charter not allowing users to supply there own any longer)
Belkin Crap Router (Which I may try and replace with something newer)

But yeah, no idea how to rectify the issue with the wireless home network not seeing the servers..... Any help would be graciously appreciated!
