Hi all, I have read several threads about the time capsules reporting having a non valid IP address, and funny old thing mine does too..... The common theme of the threads is that there is no real answer (well, that works for me anyway). I have my broadband running through a Thomson wireless router, and then connected via ethernet cable to my 3rd Gen. Time Capsule. I generally use the time capsule to generate the wireless network for my home internet. My TC has been working fine for over a year, until the other day when the dreaded amber light of doom started to flash....and yes it was the non valid IP address. Nothing I did seemed to resolve the issue, and I am confident that it was not my ISP as I could connect to the internet through the Thomson wireless router. I left it alone in frustration, and overnight the problem remedied itself. No more than a day later and I am left with the same problem. Is my TC on the way out (only about a year old 3rd Gen model)? Is it my ISP? Is TC just a bit crp as the wireless router? If anyone has the answer or can give me a permanent solution, I will send you a virtual bunch of flowers or pint of beer (whatever you fancy). As ever, many thanks!
