No internet on desktop ethernet, but 2 others OK wireless
I have an HP desktop WIN 7(64) connected to an ARRIS Cable Modem via Ethernet.
A few days ago, I installed a couple of Microft “critical updates.” After the second one installed and rebooted, most of my desktop icons were missing, the rest were rearranged, and the desktop background was black rather than the simple blue. Also, it'd changed the desktop from my classic pattern back to the pattern that came on the original installation. So I did a system restore, and that brought things back to where they were, but I could no longer connect to the internet. I also have a laptop and iPad which were still able to connect to the network just fine.
I ran the complete HP diagnostics and everything was OK. I ran a startup repair and nothing there. The green Ethernet light on the front of the Modem is flashing green. On the back, the Ethernet cable has 2 lights: the upper is flashing orange, the lower is red. When I click on the signal strength icon in the systray, it says “Not connected; no connections available.” I opened the Network and Sharing Center, but nothing on there gets me back on the internet. Time-Warner says that the signal to the box is good.
I read through many of the problems similar to this on the forum, but none of them seemed to duplicate this problem. The closest seemed to be ones about reinstalling the ethernet drivers. If I have them, I don't know where they are, as I have no installation disks for the computer (that I can find).
Here are what I think must be the applicable readings from the Device Manager:
Network Adapters:
-Qualcomm Atheros 802.11 a/b/g/n Dualband Wireless Network Module
General Tab: This device is working properly
Advanced Tab:
--AdHoc 11n: Disable
--Dynamic MIMO Power Save: Disable
--Network Address: Not Present
Resources Tab: Conflicting device list: No Conflicts
-Realtek PCIe GBE Family Controller
General Tab: Windows cannot load the device driver for this hardware. The driver may be
corrupted or missing (Code 39).
Advanced Tab:
--Auto Disable Gigabit: Disabled
--Jumbo Frame: Disabled
--Network Address: Not Present
--Shutdown Wake-On-Lan: Disabled
Resources Tab: This device isn't using any resources because it has a problem.
Anything you can do to help would be greatly appreciated. I really don't want to have to wipe out all my files and start from scratch via a system recovery operation, even though I do have my data files backed up. Reloading all the programs would take more time than I may have left in this lifetime.
