»[DSL] Need a 2nd modem
Just in case the link is excluded, here's a copy&paste of the original reply.
Easiest solution would be using powerline networking adapters. I've purchased two sets of trendnet tpl-303e2k networking adapter kits. Setup is pretty much plug-n-play. Just plug it into a wall outlet, plug an RJ45 Cat5, Cat5e Ethernet patch cable from the modem into the powerline network adapter, plug the other powerline network adapter into the outlet in your basement, plug into your PC with another ethernet cable and away you go. Plenty of flavors to choose from at online outlets such as newegg, tigerdirect, etc.. no dropped signals to worry about, wireless phones stepping on the wireless signal, microwave, etc.. Don't need a degree in networking to set them up, just plug them in, press the sync button if it doesn't automatically synchronize with your existing setup. I've had no problems with either set. Reasonably cheap solution that will expand your networking capabilities for whatever your needs are. Much simpler to plug into a wall outlet than fiddle with multiple modems, wireless repeaters, access points, support calls to try and figure out just how to set it all up so it actually works, etc.. Cost effective, hassle free and it works.
