If the cable light goes out, it is an NTL signal problem, which only an NTL tech can fix. It is unrelated to your equipment.

The router logs will not diagnose this problem. As a side-note, I think your router is over-sensitive: there are not any SYN floods in reality. If you can turn the feature of SYN-flood detection off in your router, then try doing so: it might improve your service.

If anyone understands that, their better than me!

SO it must be NTL!
Anyone offering a soloution?

If using the belkin make sure that your firmware is at the latest standard, i have suffered from this flooding on my belkin but nowt like that do a check with spy bot or adaware to check you have no trojans on your PC

Just because you don't know what something means, does not mean that that thing is wrong or malicious. There is nothing in your router log to be concerned about, and reformatting your system will achieve nothing but waste a lot of your time. What is it that you are actually worried about?

Re: Disconnects
 
Is anyone still getting a disconnection problem?

I am still getting it in here in Norwich, and the solution
so for is to disable and then re-enable my network
icon on the PC.

After which it does seem to take a while to get
a valid ip address aclloacted by the DHCP.
