wireless isolation

[72lori]

i have a TG1682G and i am unable to access my media server inside my own wifi network, but when i am out side my network i can. i beleive it is caused by wireless isolation and unable to locate where it is located to test my therory.  Any help would be greatly appreciated. P.S prior to xfinity upgrading my router i had no trouble in accessing my media server from within and outside my network.

I have  tried everything from simple reboot to completely factory reseting to no avail. I took it bake to comcast and replaced it with another router. That fixed the problem. There are fuseable links inside routers and i think it was blown out.
