@David-TP 

Thank you for the clarification.

So I presently cannot lock it to any particular cell?

I understand my network (EE UK) uses older 4G cells for their 5G network, but this thing crashes on a daily basis.

It's a shame as the cell in my previous screenshot gives a strong signal and amazing speeds of 350-400Mbps, but it keeps switching to weaker cells or sometimes 4G cells.

Does the new firmware enable cell locking to 5G LTE bands?

The problem is this X50 5G is fitted this at my elderly parents house over 100 miles away. Their landline telephone uses the internet connection so they are unreachable whenever this router crashes.

Is there any way to remotely install the firmware? I see the update is not available OTA yet.

I would rather not make a 200 mile round trip this weekend just to try to get this flipping thing to work properly.

Regards.

Thanks David

I have updated to 1.2.1 and everything seems fine at the moment.

However, i still don't see how i can lock to the 5G NSA B3 cell?  When i look under 5G Cell Lock menu, the list of bands available still only go from N3 to N78.  Should i be seeing some B bands as an option?

Thanks again

Does this cell lock feature not work after all, or am I doing something wrong??

  @David-TP 

Sorry for the delay. The router is installed some distance from my home, and I cannot access the cell lock features remotely.

But I am here for this weekend.

If I turn on 4G cell lock as you suggest it asks me for a EARFCN and a PCI number. There is no option to chose any band.

I don't have an EARFCN number as it's using a 5G LTE cell which only gives me a NRARFCN number.

Confused!

On another note. This router has been perfect since the latest software update.

No freezing or dropouts.

I wanted to cell lock to the strongest transmitter, but the router now seems to be doing the job perfectly itself. So cell locking is not so important.
