These are picked from memory and looking at the list of a similar computer. There are one, maybe two that are missing, but I don't at this moment have access to the trouble computer to find them.
Problem:
Yesterday a friend came to me complaining that their internet simply stopped working. When I checked the device manager, I noticed a long list of items, listed above, with exclimation points. The error for all of them was Code 31, or unavailable driver. I have since been able to get internet access, but many of those devices are still showing errors, and I would like to fix them.
Steps Taken So Far:
I attempted to reinstall the driver for the network card, but that had no effect. I uninstalled that card and it was successfully reinstalled, but with the same error. I didn't touch any of the miniports because, frankly, I know next to nothing about them.
I uninstalled and reinstalled the Watchguard client, which removed the errors on three of the miniports, the card driver itself, and I think two of the Deterministic Network miniports, though the exact two have slipped my mind. I would later uninstall the software and leave it that way.
I also uninstalled the McAfee privacy software (leaving the Virus Scan). Though I doubt that had any relevance to the problem, I was running out of ideas with no connection to the internet to search for solutions.
After viewing the LAN connection properties, I deselected the QoS Packet Scheduler service and the internet started to work. I then uninstalled and reinstalled this service. I was only able to test web browsing due to time constraints, and despite the errors it seemed to be working fine.
As I said earlier, I am not familiar with miniports, their configuration, or what would happen if I tried to uninstall and reinstall them.
Any help would be appreciated, though I don't have much access to the system to frequently "try" things. I am also curious to know what could have caused this problem, I don't think he made any changes to his configuration that could be to blame.
Regardless, thanks for taking the time to read this.
