Unable to connect to internet

Good afternoon,

Following the recent Windows 10 Update it took much longer for my PC to establish an internet connection. This then became intermittent and now it won't do it at all. It will say it's connected to the network, and that it has internet access (although it takes longer to get this information than it used to) but I can't connect to the internet.

When I ran the network diagnostic tool it initially came up with the following error:

Primary DNS server not responding (I can't remember the exact wording and can't reproduce it now)

Having tried some fixes it now comes up with:

Wi-Fi doesn't have a valid IP configuration.

All other devices in the house are connected fine, and I am currently submitting this tethered off my phone which is connected to the Wi-Fi.

I have tried a number of fixes suggested online:

Restarting my PC

Restarting my router

Updating my network adaptor drivers (they did need an update but it didn't solve the issue)

Uninstalling my network adaptor and then having windows reinstall and update it.

Releasing and renewing my IP address

Flushing my DNS info (not entirely sure what I was doing with the last 2, just following isntructions) Finally, re-installing windows, but opting to keep my apps and files. I do now get a slightly different error from the diagnostic tool:

Default gateway not available

None of this has got me anywhere, I can still connect to the network but not the internet. The network sign on my task bar intermittently shows connected no internet, connected with internet, not connected, but regardless I can never access the internet.

I am running Windows 10. hardware details are:

Network Adaptor - Intel(R) Dual Band Wireless AC 3168

Processor - Intel(R) Core(TM) i3-8100 @3.6 GHz


Anyone got any ideas? I'd rather avoid wiping everything and starting again if I can.

Hi mikeyrh,

Thanks for the steer. I installed the patch for my version of windows but unfortunately I am still getting the same error.

Have you gone through Fruit Bat /\0/\ 's extensive list?

No, not yet. Will post on here when I have.

I've a feeling that the wlan card might be failing though I hope I'm wrong. If nothing works then the easiest way around it is to get a dual band wi-fi USB dongle.

I've just turned my PC on to start working through the solutions above, and it does now connect, but with an incredibly slow speed (0.08Mbps).

Would this fit with the wifi card failing?

I would think so. It's not as if it's not working, it's just working poorly. Mine just died on an old laptop so I just bought a cheap dongle.
