GL-x3000 Doesn’t work on Three Mobile

So I have had this £450 paperweight for a while and was interested to see that new firmware had been released so plugged back in reset it fully then updated.

Put Three Internet sim in but still abysmal Speedtest showing 320-400mbps with 20mb upload but internet unusable and constantly hanging. If you try and download anything that’s the biggest problem it will show it downloading very slowly but once it reaches 99.5% it stops on every download.

Put the same sim back into zxel three 5g router and lighting fast no issues.

Support are no help obviously me paying only pittance for a router £450 is beneath them to even warrant a response, why are these foreign companies allowed to sell useless rubbish to countries they know they don’t work in.

Hi @GothamArkham did this issue begin after the firmware update, or has it always been present?
To improve the cellular speed, here are some tips you can have a try and see if it helps:

  1. Make sure all antennas are connected properly, and advised to use the original power adapter
  2. For Three sim card, adjust the following cellular settings through manual setup:
  1. Go to Network->DNS, change to another DNS server, such as google public dns server.
