I just moved into a mother-in-law unit. It's about at most 50 feet from the main house. My landlord has the Suddenlink bundled tv, internet with wifi, and phone. She has a desktop so she doesn't have any need for the wifi. I believe it's just there for the tenant (me). The wifi has not been reliable and is slow. I can't use netflix, youtube, web pages sometimes load slowly, router needs to be reset often, etc. What sucks is I've got a mini in my entertainment system and a MB for "around the house" all 300 sq. ft. of it. I've got an airport extreme not being used and I'm curious if this can help my situation at all. Will it be more powerful than the Netgear router she has? Will the wireless-N benefit my mini and MB? I'm pretty much looking for any options other than running a separate ethernet cable out to my place. I do have a good coaxial splitter though.
