HP 2000-412nr Laptop Won't Recieve IP

OS is Windows 7 Home Premium.  Problem I'm having is the machine connected to lan or WIFI will not capture an IP from the DHCP server (router).  It will however pickup the DNS IP's.  I can ping local IPs if I statically address but no external access.  System passes malware and virus scan.

I've booted the system with a Ubuntu disk and the LAN/WiFi works properly.  Something with the software.

Thanks in advance.

make sure that your router is properly configured like NAT to get you internet.

so you have 2 different adapters that do not receive an IP from your home router.  I assume that there are other devices connected to your home router fine, and they get IP addresses and internet access??

you say if you set a static IP you can ping locally, but you would need to add the router's IP as DNS & Gateway to be able to ping/connect outside to the Internet.

have you put any settings on your router like locking down by MAC address only?
are both your devices got their IPv4 connectors set to auto for DHCP on IP and DNS?

Other devices connect with no issues.  If I statically address, to include subnet mask and DNS info (local router or external DNS) no resolve.  I can ping locally but no internet access.

Go into device manger (control panel), go to network adapters section, expand, right click on wired network driver, choose uninstall and then reboot. Do the same for the wireless adapter if the wireless isn't working either. See if that resolves it--if not go to the manufacturer site and download the latest drivers.

Problem happens on either device of dissimilar MFG. Uninstall from Dev manager doesn't help.

what security software is installed -- AV/firewall??  Is IPv6 enabled or disabled?

can you ping the problem system from your router and other systems? have you manually added IP address, default gateway and primary and secondary DNS servers and then tested for external access? if this does not work then it is not a DHCP issue but if this does work then it is more than likely an issue with the DHCP rejecting requests from your system (then check event logs for details as to why).

Couldn't figure this out.  My guess is it had malware or something else prior to me repairing it that was removed and did something to the registry.  Ended up doing a fresh install.  Fixed the issue.  Thanks for your efforts.

Points are for efforts.  Ended up re-installing the OS.
