Seriously odd problem with DG834PN

[mrbenn]

I am using a DG834PN router for my Sky connection and have been having some issues with Noise Margins falling and line dropping, and now I think I have found out what is causing them, but it is too weird....I think it is my Ipod.
It is a 5th gen so no wireless but if I pull up my router stats page and look at noise margin BEFORE plugging the ipod into the external USB powered hub to sync/charge it, my noise margin was sitting at 13-15db, within seconds of pluggin it in that dropped below 10 and within 2 mins it was right down to 2db and line drop.
I know it shouldnt be able to have any effect on the router but I will swear it is, has anyone ANY ideas on this before I check myself into the local nuthouse?

probably a faulty USB hub/hub power supply...if you plug you iPod into the PC directly does it still drop?

nope, works fine when plugged into the main machine's USB ports, time to go Hub hunting i think
