I have a WRT54GS v1.0 running on HyperWRT v2.0b3 firmware. I have the transmit power set to 100%. On my living room WindowsXP SP2 PC (about 4 rooms away from the router) , I have a WMP54GS. I am not using the linksys wireless app., just windows zero config.. The speed is always between 100 - 108 mbps. My PC (in my bedroom which is next to the room with the WRT54GS) is also running WindowsXP SP2. I have a WUSB54GS connected via a 3ft. long USB2.0 cable to my PC's USB2.0 port. This USB2.0 port is built into the motherboard (it's not a PCI USB2.0 card). The WUSB54GS is also being used with windows zero config. and is mounted on my desk away from any other electrical device. The antenna on the WUSB54GS is pointing towards the direction of the WRT54GS (again, which is right in the next room). My problem is that the speed never goes higher than 54mbps. If the WUSB54GS is also a "Speedbooster" compatible device, how come the speed never goes as high as the WMP54GS in my living room PC which is about 5 times further away from the WRT54GS than my WUSB54GS is? Thanks for any help.
