Rut240 connects to phone but not laptop

[PLW]

Hi,
The router is working and I can pick up a signal via my mobile phone. Meanwhile, my latptop can ‘see’ the router signal but says ‘no internet connection’.

However, I CAN get the laptop to connect to internet/recognise the router signal if I connect the phone to the laptop using USB Tethering.

Any advice? The laptop is an HP ENVY x360 and using Windows 11.

Any advice gratefully received.

Thanks
Paula

Hello,

Is the laptop actually not able to reach any website? Or is the issue faulty indication on Windows?
Could you try pinging 8.8.8.8 via the CMD window when connected directly to the router to check if the issue could be DNS-related?
Additionally, is the issue present when the laptop is connected to the router via an Ethernet cable?

Best regards,

Thanks.
The laptop won’t connect to internet at all without the USB tethering from the phone. There is no ‘faulty’ indication on Windows on the laptop, just ‘secured, no internet’ message. It says it receiving the signal when I look up the RUT240 wifi properties and current linkspeed showing as 28/72 Mbps when not tethered.
I have no ethernet cable so can’t test router to laptop that way.

I’m not too techy so please explain (step by step please) how and where to ping 8.8.8.8 via the CMD window when connected directly to the router to check if the issue could be DNS-related. PS. I just typed ping>8.8.8.8 into the search bar and got ‘Hmmm… can’t find that page’. Was that the correct procedure?

To test the ping functionality, open the CMD window. It will look like so in the Windows search:

When a black command window shows up, run this command:
ping 8.8.8.8
The result should look like so if there is internet connection available:

And like so if there is no internet (could take a while):

This is what came up for a ping test. Please advise further if you can.

It looks like there is a connection. So what do I do now - what might be the problem?

Most likely your carrier is supplying invalid or unreachable DNS addresses. In this case, the easiest way to solve the issue would be by manually selecting the DNS.

• Log into the WebUI of the RUT240;

• Navigate to Network → Interfaces → General;

• Edit the mob1s1a1 interface by pressing the pencil icon;

• In the advanced settings, add 1.1.1.1 and 1.0.0.1 under the Use custom DNS servers:
  

  

You may need to reconnect to the WiFi network for the changes to take effect. The addresses of the mentioned DNS service are provided by Cloudflare.
Let me know if this helps!
