Linksys WRT54GL on Uni network

Hey,

I want to split my ethernet connection in halls with my ps3 and laptop. By using a WRT it also means I have wireless.

I've plugged my laptop directly in to the ethernet connection and set it up as instructed. I can access google, etc fine.

So, now I want to try it via the WRT.

1. Remove university ethernet cable.
2. Connect WRT to laptop.
3. Change WRT mac address to match my laptop's.
4. Connect WRT to university network.

I've done the above and the WRT is showing connected via DHCP fine. However, I cannot access google on my laptop and the WRT cannot ping sites. Does that mean the university network can some how detect that my WRT isn't my laptop and is blocking the WRT access?

The connection is probably looking for the MAC address of your laptop, try cloning it onto your router.

Do you have to go to some page to authenticate when you connect your laptop?

I registered once via my laptop and then cloned my laptop's MAC code. I've tried DD-WRT and Tomato but both won't let me access the network. Once you're registered you're good to go. I would ask them to change the MAC code to match WRT's real MAC code but the Uni tell me to talk to reception and they're ignorant.

When I do a direct connection (Uni -> Laptop) I get the following settings:

Subnet: 255.255.254.0
Router: 150.204.249.254
Search Domain: jmu.ac.uk

I've tried putting those details in to WRT too but no luck. Could it be the WRT's ID, hostname or domain? They're all optional but the WRT uses the ID for as the SSID (think that's what it's called) for the wireless.

I'll try default firmware to clone the MAC instead. I can see it's definitely a Uni -> WRT problem and not a WRT -> laptop problem because the WRT cannot ping google.co.uk
