Windows 10 PC won't find wifi after install of NBN modem, every other device connects fine

[SteveO2000]

Hi my Telstra modem won't show up on my window 10 PC even though it is quite near it, no signal blocking items, all other devices throughout the whole hose connect fine?? Any ideas? I even did a windows reinstall and have replaced the wifi dongle to no avail.

You may need to log in to your modem and turn off band steering. This will split the 2.4GHz and 5GHz networks into separate networks and your computer should be able to see them. Some dongles do not like the band steering.

Ok I just tried that but didn't make any difference, it's frustrating because it's should be a full signal where it is.

Go in to Network and Sharing Center, then Change Adapter Settings.
Open the Connect/Disconnect dialog through there and then show available networks.

If that can't see them, then select the Dongle and click on Diagnose This Connection.

It shows me lots of other networks, Telstra air and other people's modems in the area, it just doesn't show mine.

I seem to have the network now, full signal, connected, but not getting any internet??

Even though it says connected with internet access, I'm not getting anything, tried chrome and edge browsers, can't even get into mygateway/login
?

Also it works fine it I connect a LAN cable, so there's definitely internet to be had.

Try changing the WiFi channel in the modems WiFi settings for the WiFi band that the PC is connected to.

After it connects to the Modem via WiFi, run the Troubleshooter (right click on WiFi symbol and click "Troubleshoot Problems"). That normally resolves any residual addressing issues (which usually cause the no internet problem).
