Windows 7 Wireless access works ethernet connection unidentified?

[Plec]

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.

It's great to hear that you were able to resolve the issue with your network connectivity. In your initial post, you mentioned experiencing problems with your Homehub 2.0 and Windows 7 RC1. Since you've already solved the problem by reinstalling Windows and rolling back the network adapter drivers, I'll provide some insights into the initial issues you were facing:

Initial Issue:​

1. Network Connection Problem:
   • You mentioned that you couldn't access the internet or the Homehub interface via the ethernet cable connected to your desktop, even though the wireless connection on your laptop was working.
   • The "network and sharing center" listed the connection as an "unidentified network," and you encountered the error message stating "local area connection doesn't have a valid I.P. configuration."
   []Possible Cause:
   • Coincidentally, you had accidentally triggered the "SMART LAN" option in the BIOS, which is a LAN cable diagnostic function. This could have potentially caused a configuration issue with the LAN connection.

     Resolution Steps Taken:​

     • Reinstallation of Windows: You mentioned that a reinstallation of Windows resolved the issue effectively.
     • Driver Rollback: Further, you identified that Windows 7 updated your network adapter during a Windows update. By rolling back the network adapter drivers, you were able to reestablish the network connection.

     Additional Information:​

   • ]Motherboard Information: You provided details about your motherboard (Gigabyte EP43-SPL), processor (E5300), RAM (4GB DDR 8500), graphics card (ATI 4850), onboard sound, and the Homehub 2.0. If you encounter similar issues in the future, remember that troubleshooting network problems often involves checking network settings, drivers, and configurations. Rolling back device drivers and performing system reinstalls are common troubleshooting steps. If you need further assistance or encounter any other issues, feel free to ask!
