TP Link MR6400 router used to work for years until today - any ideas?

Mathemagic2 — Mon, 31 Mar 2025 21:05:10 GMT

So, have had a TP Link MR6400 with an EE sim card for a few years and all was working fine until today.

Now, it fails to connect to the internet.

I gather that EE were doing some work in the local area very recently, possibly today but it is hard to find out.

I have two different EE sims, neither allow the router to connect. Both work in normal phones. Putting a Smarty sim in the router works fine, so it seems to be some sort of configuration connecting the router to the network.

Any ideas very welcome.

Hi @Mathemagic2,

Welcome to the Community!

We don't want you to have any trouble using your SIM in any devices. Have you checked for any service outages?

Hi, thanks for the reply - after a couple of hours getting nowhere, I thought I would wait overnight and see. This morning, still no connection but after rebooting yet again, it has been fine.

I wonder if whatever work had happened hadn't been fully finished so devices other than phones couldn't connet?
