We've been using wireless hardware here for years and now the ONLY thing I use is SMC.

I've got three remote (home) offices, one running 1 AP, one running 2 APs, and one running 3 APs. The SMC APs can link together - they have built in repeating features.

The main office has one access point acting as a traditional access point, and then two acting as bridges, connecting our main building and a warehouse a couple hundred meters away with external 14.5 dbi antennas on the roof.

Here is a page I wrote up for friends that asked me what to buy:

Just look at the recomendations page. The SMC 2870W is great!
