So my modem/router keeps on restarting itselft every five minutes! It's soo annoying! In fact as I type this up, it's now offline! My modem/router is a brand new just bought Netgear DGND3700 (v2). It's less than a week old! I did hear about the v1 problems, but the modem keeps on restarting itself? That sounds like a first! 

Anyone got any ideas before I send it back to PB Tech for a replacement??
