Windows 8 connectivity issues

I recently purchased a new Windows 8 PC and since then have been experiencing continuous connectivity issues.(never had them with Windows 7)

I have BT Infinity on a wired connection with Windows 8. The modem and home hub are left on 24/7. Everytime I boot/restart my machine the network icon shows that I am connected and have internet access but no pages will load (page cannot displayed).

When I run a diagnostic the results come back with either 'Gateway is not available' or 'no DNS server'.

The only way I can get my connection back is to unplug the modem or power down the hub and then restart them. This connectivity only lasts until the next time I shutdown or restart the PC. Then I have to go through the whole process again.

Never had this issue with Windows 7.

Just to add, wireless connections to my other devices work perfect.

Any advise greatly appreciated.

Check the DNS settings in both the router and the PC. Best to have them in only 1 place, prefer the router, so they don't get confused,

Try a public DNS like OpenDNS, Google or Norton.

Is the router giving out DHCP IPs or does the PC fix its own?

Thanks for the quick reply.

Please excuse my lack of knowledge but could you expand on your suggestions.

DHCP is enabled on the hub and the PC.

Hub IP Gateway Address: 192.168.1.254

Hub DHCP Network Range: 192.168.1.64 - 192.168.1.253 (Default)

In reply to a post by Rever:

DHCP is enabled on the hub and the PC.

I'm unsure what DHCP enabled on PC means.

Does the PC's Ethernet Adapter's TCP/IP Properties show Obtain IP addy Auto & Obtain DNS addy Auto?

Do ipconfig /all in a Command Window and post with your MAC addys & names asterisked out.

Looks good! Confirms router is giving out IP & DNS.

Could it be anything to do with short, 1 day, lease? Mine go on to 2038 = Forever.

I wondered at first whether it was the 1 day lease but that period would have been the same when I was running Windows 7 and Vista with no issues. Also my wireless devices have no issues with getting an IP,etc.

I'm pretty sure it is a Windows 8/adapter issue.

Might need an adapter driver update for windows 8

I just registered after many moons of lurking as I may have a solution!

I have the same Intel NIC and there is a known issue with this device and Windows 8.
Basically, it can suddenly be detected as a different model (82579LM) and stop loading the driver, thus rendering the connection useless...

There is, thankfully, a firmware fix to correct this issue:
Intel download page with info

It's very straightforward: just follow the relevant instructions, reboot as requested and I think you'll find the problem is resolved.

Hope that helps!

Regards

Thanks for the advise.

Fingers crossed, installed the latest driver from Intel and it connected from a boot up with no problems.
