Hi,
are you talking about:
- firmware for the router
- firmware for the USB adapter
- drivers for the USB adapter
- Wi-fi utility software for the USB adapter
as these are all different things
Doing a system restore on the computer would not change the firmware on devices so I suspect you were trying to update drivers?.
Installing wifi drivers / software would not affect your wired ethernet connection - unless possibly you have manual IP settiings or have been otherwise tweaking TCP/IP.
(or do you mean router firmware and then you had to do some sort of factory reset on the router?)
If your router is giving out IP addresses and your computer is set to get them automatically it generally "just works" and without extra admin.
If you are using Windows, then you can use Microsoft update. In Computer Management - Device Mananger you can:
right-click on the device > "update driver" > let it search online
as it will only offer compatible updates.
If you don't like the results there is an option there to rollback the driver to the previous (working) version).
Note that if the usb wifi adapter has utility software you don't need it for the thing to work, just the driver is fine; Your OS will already have built-in software which is consistent whatever device you are using.
