Xbox Live, Belkin Router and MTU issue

I’m wondering if any of you clever sorts have an idea on how to fix the issue below.

I’m having a few issues with my broadband and as a result I’ve switched from my router provided by my supplier Plusnet (a Thompson model) and onto a Belkin F5D8635-4 v1 as part of the process of eliminating the cause of the fault. My problem is that when I use the Belkin router I can no longer connect to Xbox Live.

When it attempts to connnect I’m informed there’s an error and to do a network test. That test then tells me that my MTU is too low and Xbox LIve has a minimum MTU of (off the top of my head) 1364. The problem is that when I go to the router settings and look at the MTU it’s set at (again, off the top of my head) 1432.

I spent last night moving the MTU up and down, from the minimum up to 1500 and found that at no point could I connect to Xbox Live. I plugged my Plusnet router back up and it connected to Xbox Live no problems.

I’ve searched around on the internet to no avail, looked for a new router firmware (couldn’t find one), I’ve placed the Xbox in the DMZ, I’ve forwarded ports, I’ve prayed to Zeus, nothing has worked. Any ideas folks? My evenings don’t seem complete unless I’m being verbally abused by someone who’s doing their GCSEs.
