Hi,

I receive broadband via my set top box which I have wirelessly enabled with a DSL router.

I was using an old Pace box and I set the router's config to clone the MAC address of my PC's NIC and everything was working perfectly. However I've have just upgraded to a new Samsung SMT-2110C set top box and now I have no connection.

I can get broadband with the network cable plugged directly from the STB to my PC. However if I plug the STB into the router I have no connection. The PC's NIC address has been cloned within the router.

I have noticed that I now seem to have a static IP (rebooting does not change the IP as it did on the PACE), so I have configured the router for a static connection with the exact same IP, subnet and default adress that I see if I ipconfig with the working direct PC to STB connection.

It is therefore totally illogical that the connection does not work. The exact same setup worked with the old Pace box but with the Samsung it does not.
The PC's NIC MAC address has not changed and besides it is registered with the new box as the direct PC connection works.

The only other things that I can guess making a difference are:

- the cable required between the router and stb (crossover/straight)
- the MTU setting that exists within the routers config (currently 1516)

Any feedback would be appreciated as I simply have no idea!

Thanks,

Rob.
