@ExoticFish, why not? Is there a thread here where I can read about this modem? Or do you mind explaining it to me?
If I may detail that advice a bit further?
Comcast does not supply any customer routers (anymore), rather they can supply you with a wireless gateway. Folks will tell you (endlessly!) about these devices being notoriously poor, and they are correct.
What compounds these modem/router combo units is that Comcast controls the firmware, including which user-features are accessible to you. You are infinitely better served by a cable modem (or emta modem in case of phone service) and a quality stand alone router.
I really am not sure that your Cisco E2500 is the culprit or not...but at the same time, from a peace of mind point of view, perhaps a new router would not be an unreasonable purchase, but I would absolutely recommend against getting a wireless gateway.--
