Almost 6 years in, so it's not my first rodeo here:
2 xboxes, both wired in on N+speed wireless gaming adaptors to a gaming n-speed wireless router. set-up has worked great for YEARS. Downloaded the new update, and now it takes ATLEAST 4-5 minutes to even load up the dashboard, and I cannot connect to xboxlive under any circumstance on either box. The network and the internet are connected. I've run thru every help-wizard slide, deleted my cache, restored factory settings, even tried to force a static IP thinking something is hopping spots in my dynamic set-up.. Nothing. I work for Comcast, my ISP, so I know its not my ISP provider. I've even hardwired into the modem directly, still no success on connection to XBL.
I have a sneaking suspicion it was the new update...but i doubt i can be the only one. Anyone else experiencing it too?
Help, my XBL-Breathern! You're my only hope(s)!
