Three 5G broadband - UPDATES broke my SMB/NAS, can't log into the router

[456]

It seems that recently, Three have applied some updates to the router and the admin app. Now, my SMB/NAS connection is broken and I can't log into the router.

We have had nothing but problems ever since we re-joined a year ago. The Zyxel router is a nightmare. The customer support is a joke.

Can someone help figure this out? 🙏

You need to modify your APN settings to IPv4 (Happened to me recently):

Hi. My router is Zyxel and the PDP Type is already set to IPv4. 😕

OK, I can't log into the router admin as 192.168.1.1 has an invalid certificate.

I had to override that (not a good idea), and I could see that all my connected devices are now IPv6 instead of IPv4, which is probably why I can't connect to my SMB/NAS.

How do I revert to IPv4 for all my connected devices?

Sick and tired of Three and their horrible equipment. @JonathanB
