Unable To Get To Internet Through Wireless Router/ISP DSL Router Combination

    I know this is probably more of a nets/comms issue but there was a similar post there a few days ago that nobody replied to, so here goes.

    I recently bought a 3com router/wireless card bundle from Komplett. What I am trying to do is connect to the internet using the router through my (UTV provided) Creative DSL modem blaster (not sure of the exact model as I’m in work right now). The plan is then to connect a laptop wirelessly for file sharing and internet browsing amongst other things. The wireless link to the laptop worked more or less instantly once the drivers were installed for the PCMCIA card & I can share files between the two machines with no problems(the other being my desktop).

    I have setup my router as per the instructions that came with it. All link lights are on the 3com router are lit (solid green) indicating that the Ethernet connection to my machine is working and the connection from the cable/dsl port on the 3com router to the Creative router is working also (connected using the provided CAT5 cable). The problem is that I can’t get out to the internet at all. I have reset the 3com router back to default several times and went through carefully configuring it again step by step.

    I have selected PPPoE as the protocol and entered my UTV username and password details (I left the ‘optional’ fields of primary/secondary DNS servers & Hostname blank as suggested as I didn’t know them) but I am unable to enter the correct MTU value of 1500 as the highest the router can go is 1492, so I don’t know if that makes a difference. I have turned off the XP firewall also. Originally I had set my 3com router IP to 192.168.1.2 during setup as the Creative router was set to 192.168.1.1 by default. I came across a possible fix for problem suggesting that both routers should be setup on a different subnet with DHCP enabled on the second router, so I set the Creative router to 192.168.1.2 & the 3com to 192.168.2.1, disabled DHCP on the Creative and enabled it on the 3com but still no joy. I have also tried updating the firmware on the 3com router which made some extra features available but didn’t resolve the issue.
    Also, I don’t know if this is relevant but the OS is XP and I’m using Firefox. The NIC on the desktop is on board also.

    Any help/suggestions would be greatly appreciated.

    Can you put the creative modem/router into bridge mode so as only the 3Com is doing routing&DHCP.
