Hello, I bought the WAP AC LTE6 kit (wAPGR-5HacD2HnD&R11e-LTE6), hoping that I'd get at least the same speeds compared to my ISP's router, Huawei B525. However, the difference is drastic.
The Huawei router reaches 12.3 Mbps download and 2.2 Mbps upload, which is quite bad for LTE, but that's the speed it consistently reaches in Speedtest.net.
The Mikrotik router reaches barely 5.4 Mbps and 1.5 Mbps upload, so it manages to perform even worse! Even though the device stands in the exact same location the Huawei router did and uses the same exact SIM card. Why would it perform worse?
I've tried changing bands around but I haven't gained much. One of the bands allowed me to pull 8 Mbps but only push like 0.4 Mbps, that's not a compromise I'm willing to take. And besides, this device has an LTE6 modem, shouldn't it be using multiple bands just like my Huawei router does?
I've upgraded the device to the latest stable RouterOS version. Changing the MTU between 1400, 1480, 1482 and 1500 provided no improvement. I'm attaching screenshots of speedtests done with both devices (connected with a 1 Gbps Cat6 cable) along with cellular information from both.
