5G hub, v poor performance

[JohnJ]

I ordered a 5G hub (NR5103E) which arrived last week. I'm in a good 5G signal area for Three - the mast is a couple of hundred metres away. Typical download speed is 5mbps - pretty damned slow! The hub won't connect to 5G

I put the supplied SIM in my own TPLink hub (4g only) and I get reliable download speeds of 35-45mbps.

Three sent me a replacement 5G hub which arrived today. This one does connect to 5G, but download speeds are no better.

It's a pain trying to talk to Three on the phone, I was on for an hour yesterday, trying to explain the problem.

Has anyone else had this problem?

My thoughts now are that I just cancel the contract and buy a PAYG SIM to use in my TPLink hub.

No idea of the firmware version of either of the hubs you've supplied (two received so far, same performance). How would I find that out?

I'm currently using my 4G TPLink hub with your sim as it's 8-10 times faster than your 5G hub.  The latest hub from you is disconnected and has been re-boxed ready to return.

No problems with 5G according to your network status checker.

Your team advised that there was likely a problem with the hub so they exchanged it for another. They didn't offer to call me back.

I'm not getting anywhere with this - I'm cancelling.
