NR5103E No 5G Tried everything

[midge5]

I have the 3 Zyxel NR5103E Modem/Router and no matter what I try I cannot get 5G, I have tried all suggestions on the forums too, still no luck, I transfer my SIM to my phone and 5G pops up straight away with 3 to 4 bars of signal strength no issues, I can tether my computer to my phone but then it means I have to leave my phone at home which isn't really an option, all I get on the Zyxel is 4GLTE, the firmware is upto date using the b12 version.

Any Ideas?

Hi

Three has a help page for this router here

There is a useful "fix a problem" tab - does that info help

Hi, I have just been through the "Fix a problem" page and a new sim is being sent, don't know if that will solve the issue but it's another process covered, will have to see when it arrives.

Thankyou for your response, much appreciated.

Hi @midge5,

Thanks for trying the troubleshooting, Let us know how it goes with the replacement SIM. I'll help get you in contact with some colleagues that can help further if it's still an issue.

Thanks,

Hi, Replacement sim did not work in a successful 5G connection, the result is the same as my previous sim, I assume it's a faulty router but I think I will manage on the LTE until august when my contract is up.

Hey @midge5,

That's disappointing, but we can definitely still get it sorted if you're in contract for a few months. 5G makes a huge difference to the speeds, and we don't want you to miss out. I'll send you a private message that'll link you to more help with an exchange, in case you change your mind.

Bars on the phone are usually an indication of the voice signal strength not data. I assume that you have exhausted the skills of customer service on 333?

Last person who posted this problem got a replacement from 3 and problem solved.

I have tried but no luck there, apparently a mast issue but my phone connects no problem as mentioned (With 5G indicated along side signal strength), I have been through the "Fix a problem" and a new sim is being sent, though from what I've read this may not be helpful, will have to see I guess.

Thanks for your response.

As I mentioned I did all the same as you and the new sim never worked , the new router did though
