What I'm using is a Tenda wireless-N router that I bought for $15. It's upstairs and I'm in the den downstairs with my laptop where it works just fine. It also works on the opposite corner of the upstairs with a desktop. If you need a more powerful router, you can buy the ones with two or three antennas, but the $15 Tenda works fine for me. If your old router is wireless-G, you'll be pleasantly surprised at the increased speed and distance of wireless N.
Our wifi router seems to send out an awful signal. My husband is constantly booted and the kids computer downstairs lags horribly. We have an older Netgear N150 currently. Does anyone have a suggestion for a decent router that will send out a strong signal to both stories of the house. Or if that isn't possible, perhaps a solution on how to boost the signal.
Thank you for your time,
