I just picked up a R11e-LTE6 to test in place of my Sierra Wireless MC7455 connecting to AT&T in the states. With the MC7455 on router OS v7.0beta4 on a hap ac2, modem in a USB enclosure with 2 yagi antennas, I'm able to get about 40mb/s down and 5-7mb/s up. What I would like is some more insight on the LTE interface page with the MC7455, but that will come in time with support, I hope. In the mean time, I tried the R11e-LTE6 since it/s CAT6 and should support CA like the MC7455. What I'm seeing is that it will connect to either band 12, 17 or 2 primarily, and only sometimes if the primary is band 2, it will show 2CA with band 5 but then drop right back up. Speeds on any of the bands don't compare to how the MC7455 performs and it might be a combination of the low band distance and the high band 2 performance. The MC7455 also has bands 29 and 30, also used by AT&T but I'm not sure of those are coming into play. With the MC7455 connected to the routerboard, I can't get access to the AT commands to check anything, and if I plug it in my laptop, I can get AT commands but for some reason won't connect with data so I'm unable to check speeds. I know the MC7455 connects with CA, even if the screenshot i was able to grab shows inactive.
Some other posts show some issues with CA dropping. Is anyone able to get CA working? Thinking of trying a Telit LM940 too.
I should add that I'm experiencing the same thing with stable and testing releases of router OS
