went to comcast service center one day n tech there said i needed an upgrade to my modem. so they gave me a DOCS 3.0 Ubee DDM3513 modem. it seems to handle the internet fine, but when i connect to a video game via xbox360 within ten mins im disconned n reconned to a different host.
i just tried to get comcast to fix it. the rep told me that everything should work fine since i both had the new modem n blast service. why dont they have true online tech
