I've bought a MikroTik LHGG LTE6 kit to boost reception for my home internet because the 4G connection where I live is quite unstable (and 4G is the only way to get internet here). However, compared with a standard router that comes with an internet subscription it made things worse. I've tried rotating the antenna through 360 degrees and adjusting so that the numbers are highest.
With my Huawei B535-232 (located indoors) the connection had the following numbers connected to the cell with id 36028167: RSRQ -7dB RSRP -100dBm RSSI -73dBm SINR 8dB
Now I'm getting number such as these, pointing the antenna westward towards one of the cell towers (this is where a neighbour's professionally installed LHG antenna is pointing). Note that the antenna is installed on the roof, whereas the Huawei router was indoors.

I'm not sure if that's related, but quite often the link goes fully down and network connection is lost. It comes up by itself after a minute or so.

I'm not sure what I'm doing wrong, because I've heard that just replacing the regular router with the antenna has doubled their speed and increased stability. Am I missing something regarding the setup? I haven't connected the grounding wire – that can't be it, can it?
I'm now thinking of returning it (I have a week left for a no-questions-asked return) and would like to understand if it's me being dense or the antenna being defective. And whether I should get an identical model or go with an omnidirectional antenna such as Huawei B2368. Thanks in advance!
