My parents recently got comcast high-speed internet. The guy came in and he installed a wireless cable modem in there room. Not only does it broadcast the wireless signal throughout the house but it is also the cable modem. I have a wireless USB adapter in my rom that picks up the signal from that modem. Well here's the problem sometimes the connection is not as strong as I would like it to be and it, and I play alot of online games, ones that require alot of people to be on the screen at once. So what I would like to do is set up another cable modem in my room. I have a cable line in my room, and I'd like to have a hardline connection to the internet instead of the wireless. I want my parents to be able to keep the modem in there room, and have that continue to broadcast the wireless signal but I'd like to set up my computer to have a hard-line.
Also I can pick up internet signals around my neighbor hood, and there is a free netgear connection that I can use, but the signal is very low. I only have a 802.11b USB adapter. So my questions are:
1. Can I set up a cable modem in my room, that will not interfer with the wireless connection that is already in the house?
2. If I get a better adapter, say an 802.11G USB adapter, will that increase the signal strength of the netgear connection that I am picking up? If not what would I need on my end to increase that signal strength?
