I have an office over my garage (detached from my house but only about 30-50 feet from modem in house). The wireless signal is very weak. When I had the modem in the garage office, the wireless signal to the house was weak. Comcast thought their new wireless modem would address this, but it has not. So, I have run a cat5 cable from the modem across the yard to the garage and hardwired it into a Linksis WRT54G Wireless Router. Although I can connect to the router wirelessly, I cannot get internet access on my computer. I called Comcast, and they said they would have to disable the wireless signal from the modem if I want to activate the wireless router. I do not see how this will solve anything. They mentioned that to have 2 active wireless signals would create interference. Is this true? I can hardwire my computer to the router, but I also use a laptop and other wireless devices that I would really like to have a strong signal for. Please advise.
