I recently had Xfinity Internet installed. I have a Netgear WNDR3300 router for wifi. I have never had any trouble in the past when using WOW as my cable provider. Now that I have changed to Comcast my wi-fi keeps dropping or it just doesn't work at all. Most of the time I have to shut down the cable modem, shut down the router and then shut down the computer. Then I turn the modem back on and let it light up. Next I turn the router back on and then my computer. It's a complete pain. I have had this for just over a week and have only been able to use the wireless a few times. My computer is a Dell running Windows 7. I have read that my router may be considered at the 'end of its life' and am wondering if I should upgrade the router or is there something else I should be looking at? Any help would be great. Neither Comcast or Netgear's help sites are very helpful for these kind of issues. I asked Comcast about it and they told me to talk to Netgear. Help.
What are the indicator lights doing on the modem when this happens ? What do the modem's signal stats look like ? Try getting them here; http://192.168.100.1
Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
What is the exact make and model number of the modem ?
Does the same thing happen with the router out of the mix with a computer directly connected to the modem ? You will have to properly powercycle / reset the modem when doing so and then again when you re-insert the router.

Have the same system and had the same problem. Found out Netgear provided free routers but were defective so Comcast dropped them. Comcast now has a unit with the router built in. Just received 6 weeks ago. Modem, router and telephone modem all in one unit. Model AR TG862G. Comcast shipped and sent a return box for the old hardware.
