Wifi hotspot giving "No internet, secured" on Huawei P10 with Android 8.0.0 This is driving me bonkers. I've been on a chat with Vodafone and they sent me APN settings, but that hasn't helped. I've tried the settings in this thread.
And that hasn't helped this time (it did a few months ago!!) 

If I drop to a CMD prompt, on Windows 10 I can see that DNS is not working.

C:\Users\music&gt;nslookup google.com
Server: UnKnown
Address: ::1

*** UnKnown can't find google.com: No response from server


which is really odd. 

So, I tried to hit the IP address of one of my own web sites, which works.

It's definitely a DNS problem, and I guess the DHCP on the phone is not giving me any DNS server address to use, but how do I force it to do that? I've tried putting static details, and just using 8.8.8.8 and 4.4.4.4 as DNS, but it didn't help at all.
This always happens if Vodafone send an update to the APN ... to fix it, just reset your APN settings back to default and select either pre-pay or post-pay, whatever's appropriate for your sim.
