Linksys AP (not sure of model number, sorry) which has about two dozen machines using it.
Problem: An office down the street, which gets a signal right at the window, but nothing usable inside.
Interim solution: I've got a Mac Mini leaned up against the window, which is connecting to the Linksys, then "sharing" internet out via the ethernet cable which is going to an Airport Extreme base. The Airport sends out its own 802.11 signal and a half dozen laptops are routng through it.
I'd much rather use something made for this purpose and take back my Mac...
Price isn't critical (within reason). Reliability and simplicity is more important.
Suggestions gleefully accepted.
