Wired connection issue

[FitzyJM]

Hi all, Had a friend call me up saying he was having an issue with his internet connection. Having worked for his ISP I went round to have a look and carried out the following:

Windows 7 Professional
Onboard atheros ar8121/ar8113/ar8114 pci-e ethernet controller driver

disabled - reenabled nic
uninstalled and reinstalled nic drivers
netsh firewall reset
netsh winsock reset
netsh int ip reset resetlog.txt
changed cable
checked ports on router with another pc all ok
stop and start of DHCP client and DNS
started in safe mode and get same issue
ran Malwarebytes and SuperAntiSpyware no issues found
Used static address information
System restore

constantly got 169 ip address so installed another NIC (Realtek) and then got network cable unplugged. Had them to reinstall windows and just got a call saying they were having the same issue so was wondering if anyone else had any suggestions of things to try.

Many thanks in advance.

Check in BIOS for NIC settings, check for BIOS update, swap out & try different router, try hooking up directly to the ISPs cable/dsl modem/router... Try a linux live bootable disk to see if issue still occurs. if all else fails low level format hdd then do reload. If it's a rootkit, sometimes doing a windows reload does NOT eliminate the rootkit. I use a utility called CBL data shredder to write 0's or 1's to an hdd. It can be downloaded here: http://www.cbltech.ca/data-shredder.html hope this helps!

Cheers for the reply ITLogicSystems, got it sorted by updating motherboard drivers and got new NIC working, had checked NIC in BIOS, didn't need to swap out router as checked all ports on router and checked router for issues with MAC, changed MAC as well and router is working all ok (supplied by cable ISP). Good shout on live bootable disk will try that in future if I get any issues like that again. Cheers for the link to CBL data shredder.
