I have a Homehub 2.0 that has worked flawlessly up until now. I am using Windows 7 RC1 and I don't have any bt software installed. I can't access the internet or the homehub interface via the ethernet cable connected to my desktop - yet i can wirelessly via the laptop. When i open up the 'network and sharing center' it has it listed as 'unidentified network'. When i try to resolve the problem it comes up with the error - 'local area connection doesn't have a valid I.P. configuration'. I'm afarid my network knowledge is very lacking as it's not an area i've had to trouble shoot before - i've been lucky up until now. There is one other thing - just before this happened i was in the BIOS and accidently pressed enter on the 'SMART LAN' option it's a Lan cable diagnostic function' - is this just coincidence or has this caused the problem? (could it have confused the hub or the port itself?) I've reset the hub and also unplugged it for several minutes - but to no success. It's got me stumped and i've spent 2 hrs googling for a solution but i've either not recognised the answer or i have a wierd problem which is why i wasn't getting any hits. Spec: Gigabyte EP43-SPL, E5300, 4gig DDR 8500, ATi 4850, onboard sound and a Homehub 2.0 Any help appreciated. EDIT: Problem resolved. Re-installed windows - brutal but effective! Additional: I found out the actual cause, for anyone having the same problem and using a similar mobo - Winodws 7 updated my network adapter during a windows update. I just rolled back the drivers, this time, and the network was identified again.
