I have recently purchased the wrt54gs and usb54gs to upgrade my wireless b linksys kit to increase wireless speed. I have also purchased the linksys hga7t 7bi high gain antennae. My network only goes through one wall and the wireless distance is less than 10m,however the signal is always low,and whilst my wireless b network never went below excellent. I have tryed changing the firmware to get the signal power option, but the poor signal remians. Any ideas?
