Re: internet keeps dropping

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.

Re: internet keeps dropping

you may have to plug in directly to your modem to access that page. Once it loads it usually will take you straight to the Status page which was what he was requesting above.
