After getting the WRT54GX4 and WPC54GX4 i am still in need of additional signal / performance for my SOHO environment. This unit doesn't support aftermarket antennae (right??), and linksys doesn't offer either bridge or extender functionality in this router or the wap54gx4 router. Anyone have any suggestions on how i can boost the signal, and still utilize the SRX400 signal, wpa2 encryption, etc. ?
