5GEE Router - Slower speeds than Mobile

[JakeH03]

I recently got the 5GEE Router, unlimited package.
But I only seem to get maximum 20mbps down/up, whereas on my phone I manage to get 90mbps down/up.

Is there any way I can improve my speeds from my router without having to buy an antenna?

I am connected via Ethernet, and have also ran speed tests from another device connected by Wifi, both have the same speed. But if I disable wifi and use the mobile data on my phone, my speeds are much higher.

Thanks

Thanks,

Turns out mine is quicker on 4G

They think it is not connecting to 5G properly so asked me to leave it on 4G only then switch it back to 5G then submit some speed tests to them
