Just happened recently with this router,bought from router switch,import, cant connect to the TV through wireless or lan cable,ive tried resetting the router, the tv.

Tried it at the girlfriends, so different mast, and 5G , still the same.

EE Sim, Three sim same, tried different TV'S , pcs and mobile fine though.

Put the sim in my B818 and its fine through lan etc,so its the H112

Tried different dns on the router, apn,s , any ideas?

Really am stumped.

would love to try changing the firmware on the router, but cant find any files anywhere, the auto update doesnt find any either.

Check DHCP parameters on the router and make sure that the TV hasn’t got a fixed IP address outside those parameters.

This is what shows up on the router

Looks like it is connecting. hmmm, Which APN are you using three.co.uk (CGNAT) or 3internet (No-CGNAT)?

Can you manually set DNS server on the TV?

Also the tv most probably being android (as I've had this issue before), try not allowing it to use the router for DHCP and put its IP in manually. That may work.

So that's all fine as far as IP addresses are concerned.
I think your problem is going to be on the TV rather than anything else - so forget SIMs, APNs etc.
Look at the Gateway, DNS and DHCP setttings on the TV and see what values it is using.

This is the same with the 3 sim and the EE sim, so not sim related, ive tried both sims in my B618 and the tv works fine through lan etc.

Its the H112-372 thats the problem,its the same on my samsung tv and 3 different panasonic tv's, tried different dns

Odd thing is it was working fine a few weeks ago, factory reset the router as well.

Then you have to conclude that the router is faulty. Return under warranty, I hope!

I (think) you're using opendns on your LAN - 206.67.222.222 - perhaps they've changed their policies and now block something that the TV's use to connect through. It's worth trying to go back to the default (Three's DNS) or trying a different DNS provider. At the least it'll eliminate your DNS provider being an issue

Edit, I just saw that you say you've tried different DNS - where, in the router or in the TV IP settings?

Tried them in the router and tv, was using google dns before, like i say, everything fine on my other router B818.

Sure is an odd one.

Tried tethering your TV to a phone to eliminate the network being the issue? Though it'd be unusual to have the same issue with multiple providers...

Oh, hold on. Are you using the same ethernet port (the LAN/WAN one) for all the TV connection testing? Is the router ethernet settings set to 'LAN only' or auto? The routers sometimes get the connection type wrong with Auto, thinking it's a WAN connected. Forcing 'LAN only' ensures the router does the right thing every time.
