O2 data SIM on Zyxel 5103e router

[Cocat2517]

Hi

I have a Zyxel 5103e router that is a Three branded router. I'm told it's unlocked and I just need to change DNS/apn settings to get my O2 data SIM to work on it, however I'm struggling with how to do that.

I've added mobile.o2co.uk with 87.194.0.51 as a DNS but it's not connecting. Is this correct and what else do I need to do?

Thanks,

Is there something about constant reboots in any of those 156 pages?

Thanks, I'll check it out. Can't see a search option on that forum so not sure if there's any reboot related messages.

If I remove O2 SIM card and reset to default settings then the problem goes away, it stops rebooting.

It is in the top right hand corner of the page , and you can always signup and post a question...

Possibly, as its more of a tech resource for people who know what they are talking about....

Cheers, search is only visible if you're registered, which I now have.
