Windows 7: WIFI card trouble

WIFI card trouble

All of a sudden my USB WIFI card has been acting up and giving me a very slow speed or failing altogether. I have tried a repair install, removing all network adapters except the USB NIC, removing all unnecessary programs, ran safe mode with networking same result.

In Event Viewer I see these two errors all the time.

WLAN AutoConfig service has successfully stopped.

WLAN Extensibility Module has stopped.

Module Path: C:\Windows\system32\Rtlihvs.dll

I have Googled these events but nothing solves my issue. I'm at a loss. I'm going to do a chkdsk next.

Do you connect. Via Windows WiFi or third party one uses its own connection and stops Windows WiFi and Windows uses its own service? First thing to check if any new routers have appeared on your channel as that's most common cause change channel in router

Well, I think I solved this one. After not seeing any other errors in the Event Viewer I wondered about my router. So I rebooted my router and now my pings to Google DNS have went back to normal and my Internet speed is back to normal.

I've never had to reboot this router before. It's an ASUS router flashed to ASUS Merlin. It's been great thus far.

I looked at the connections and didn't see anyone else there just in case I had a hacker in my mist. Odd thing was that the computers connected through ethernet worked fine. It was just the WIFI that was wonky. My phone worked fine and so did the Amazon Echo Dot. Although, Twitter did give me a few issues, but I thought it was them and not my router of all things.

So moral of the story. If you have WIFI trouble, try rebooting your router first.

Oh! I use channel 11 because I know channels 1, 6, and 11 are non-overlapping channels.

I'll mark this one solved tomorrow night so long as everything stays stable.
