NR5103E won't connect to 5G

EddersD — Fri, 04 Nov 2022 14:32:08 GMT

I just set up my new router and I can't connect to 5G, I seem to be limited to LTE only. My phone connects without issue.
Firmware is V1.00(ACBJ.0)b9 and I've been reading about b10 solving some issues (although those people were coming from b8). Any way I can force this update? I've tried looking for the firmware download in Zyxel's website with no luck

Hi there.

Sorry you're having issues getting the router onto 5G. The b10 software is generally what enables this to work. The router normally updates automatically overnight when idle, and then reboots.

Can you confirm if the router has done this since you posted?

Pete.

It's been a week and there's no B10 update yet.

Hi @stephen,

Welcome to the Three Community.

This definitely sounds like this could be a hardware rather than software issue for you. Please let us know if you're running into any similar issues with the replacement though.

Thanks,
JonathanB

Hi @BigBoss,

This is really odd, my understanding is that this is an automatic update. Sorry if I'm asking you to repeat anything you've already done, but just to confirm have you tried rebooting the router, leaving it switched on overnight, and if those fail a factory reset?

Let me know if none of that seems to force the update.

Also having the same issue here. It arrived today, have set it up. It IS on b10 firmware, but only has a strong LTE signal, nothing on 5G. Phone connects to 3 5G strongly here.

So, I found a fix for this.

If you log into the router settings, menu bar on the right -> Network Setting -> Broadband -> Cellular Band.

If you change Band Management to manual from "Auto Selection" and select B1, B3 and N78, this seems to force 5G to kick in.

I have done all of that. In fact factory reset it twice I believe. Nothing prompts the update.

Thanks for confirming this @BigBoss. I'll send you a private message to get a bit more info that I can use to look into this further.

Excellent, thanks @cmcquillan. @stephen, let us know how this goes over the next few days. 🙂

I'm having the same issue. Received the router yesterday and no 5G. It was on the old firmware, it has updated it over night but no change to connectivity.

Spoke to Three technical support who confirmed no issues with the network in the area but couldn't get through to the higher technical team so said they would contact me back within 72 hours.

Was previously on their 4G broadband which I never had a problem with hence me upgrading to 5G for the better speeds but seems like technical support have no idea what the problem is.

Pretty poor that something sold as a 5G router has problems connecting to 5G.

Hi everyone,

Thanks for flagging up these issues with connecting to 5G. I'm happy to confirm that we've got a firmware update in the testing phases for the Zyxel NR5103E router. We're spending some time making sure it fully addresses these issues, and then we'll be rolling it out to everyone soon.

Hi JonathanB,

I have the same issue where my router will only connect LTE and not 5G yet my mobile shows full signal and 5G. Could you add me to your list for any rollout information.

Thanks,

I'm in the same boat as everyone else solid 5G connection on my iPhone when placed right next to the router but the router itself is only connecting to LTE.

Router has updated to the b12 firmware but nothing seems to have changed.

Please add me to the list for any future updates. I see some people have been succesful with a new router so perhaps there's a bad batch - does anyone know how we would go about getting these replaced?
