Carrier Aggregation

Hi everyone,

All new to me but slowly getting there. I need some help if you can? I can get internet on both Bands 3 & 20. When I select both bands it chooses Band 3 as primary but nothing in CA. I find this connection to be unstable but can get reasonable speeds when it is working well. The SINR appears to fluctuate quite a lot & I think this affecting the overall result. When I select Band 20 only my result is a lot more stable although at a considerably lower speed. So, my question, should I be able to get CA? Is there anyway I can use the command line to get it to work? I have attached the details of both the band 3 & 20 in the hope that someone can help. Also, from what i’ve attached am I getting signal from different towers??

Many Thanks
