Hi ibbill, no, you cannot use both at the same time. You can put the wireless modem into bridge mode and deactivate the wireless signal and only use your own router. Just make sure to run a CAT5E cord from port 1 on the modem to the internet port on the router. I am doing that right now because the wireless on the cogeco modem sucks major monkey balls.
Re: [INTERNET] Cogeco Wireless Modem Keaters and exseven thanks for your quick replies and help.Was just installed at my daughters house they have an autistic daughter and she is on the internet with the games and education programs all the time.
If they run into trouble with the service or problems with the new system will post back and maybe I can get some help for her how to do the couple of items you mentioned.
Thanks ever so much for your help. The one they just had installed is the ultimate 30. Hopefully for their sake it works out okay.
