before my desktop was assembled, i had a wireless router that only covered about half of the house. This wireless network reaches my laptop and xbox, but does not reach the desktop because it is out of the range of the wireless signals since the wireless router is on the other side of the house. Then i came up with the idea that i could use an old 2wire router that's not wireless, on my desktop via ethernet. I purchased a DSL phone line splitter filter, and a 50 ft phone line cable (the same things that are used on the wireless router). I installed everything but the router says that there is no broadband signal coming in, while the wireless router works fine without any problems. is there an issue with 2 routers working at the same time?
