My B315 Rural Broadband used to frequently drop to 3G from 4G, however now it drops to 2G.
Now 3G is not shown as a available freq.
I have tried many times to manually fix it to 4G, unsuccessfully, I understand to make a phone call it drops to 3G, but now it drops to 2G.
I am in Outer Marborough Sounds, using Bulwer mast - I think.
Reflected signal off hill, but with 1 bar on 4G getting up to 25mbs.
Appreciate any ideas
