Im having trouble with signal strengh and lower speeds in the bedroom of our apt. Time Warner provided a Ubee router that sits ~75-100ft. away from the bedroom on the same level but it is an old house and perhaps lead in the walls contribute to lost signal strengh. Without moving the router closer, what would be my best bet for a better signal? I would be glad to buy larger antennas for my current router or swap out the ubee entirely for a higher end router like a Linksys e4200 if I knew it would make a significant difference. I assume the range on the TW provided equipment cant be great on signal range. Thank you.
