I finally got my F5D7132 wireless repeater working. The trick was to ignore all the auto-negotiate 'one push setup' rubbish and actually connect to the web interface of the device. I don't use windows, so the installation CD was no good to me, but I found some docs from Belkin that the NIC for the device is on IP by default. The trick was to connect my laptop via ethernet to the repeater and configure the laptop nic to be another address on that range ifconfig eth0

Then I was able to point my browser at to configure the repeater, adding the right SID and connection details and manually finding the right wireless network - Yay!
