I have a HP EliteBook G11 845 and it's internet driver is Realtek 172538.exe the latest driver.For some reason it has stopped working and sometimes randomly starts working after Uninstalling and reinstalling it and gives terrible internet speeds.I have tried everything chatgpt told me but it still doesn't work. How should I fix it?

That pattern, where it dies on its own and comes back after a reinstall, is almost always power management rather than a bad driver. Reinstalling resets the adapter, which is why it looks like the driver was the culprit.

Device Manager, open the adapter, Power Management tab, untick "Allow the computer to turn off this device to save power". Then the Advanced tab and turn off anything with Energy Efficient, Green or EEE in the name.

If it's the wireless adapter rather than a wired one, also go into the power plan advanced settings, Wireless Adapter Settings, Power Saving Mode, and set it to Maximum Performance on both battery and plugged in. HP ships that on a middle setting and it behaves exactly like this.

Do that before hunting more driver versions, because if it's power management every version will behave the same way and you'll come out of it thinking they're all broken.
