Hi, we just bought this router a few weeks ago.

It works pretty nice at day, but close to midnight it starts connecting with a tower far away (9km) with terrible download speeds.

Its unusable at this point, i tried everything. I dont eather understand why it connects to the bad tower, i checked the values 1 min before this happens. (we have 2 external Yagi antennas)

Closest BTS at 4km:

N78:

RSRP: -88dbm

RSRQ: -11db

SINR: 12db

B28:

RSRP: -83 dbm

RSRQ: -9db

SNR: 16db

The values look good, but for some reason it decides to connect with the one far away with negative SINR values and bad RSRP,RSRQ values. 

What could be the reason. Any chance we get cell lock like the deco X50-5g ? 

Else i need to return the NX200 and look for another device as long as i am able to.

Please tell me as soon as possible, thanks.
