The WRT54G-TM (TM stands for T-Mobile) is also called the T-Mobile "Hotspot@Home" service. It allows calls to be made via T-Mobile's GSM network or via WiFi Unlicensed Mobile Access (UMA), using the same telephone and phone number (a special dual-mode phone designed for the service is required e.g. Blackberry Pearl 8120). Additionally, once a call is in progress, one may transition from WiFi to GSM (and vice versa) seamlessly, as WiFi signal comes and goes, such as when entering or exiting a home or business. A special router is not needed to use the service, but the T-Mobile branded routers are supposed to enhance the telephone's battery life. This is the only known tweak to the TM version of the firmware. The hardware appears to be like WRT54GL however has 32MB ram and 8MB flash. Upgrading to third party firmware via software is now available!. View the DD-WRT website for instructions.
Might want to consider relocating the router to best wireless effect. According to this you can use a different router. But you really need to ask why they aren't using GSM when weak wifi signal.
