Hi!
I noticed having really crappy coverage with the 5GHz band.
For example when being only 2 meters away from the router the phone shows a weaker signal for the 5GHz network when choosing what network to connect to.
Following numbers I got using my Nexus 4 phone (with plastic cover) using the WiFiAnalyzer (open-source) by VREM app.
Being next to the router, about 2 meters away I have -46dBm for 2.4GHz and -67dBm for 5GHz.
When being away about 6m but with direct line of sight I get -53dBm for 2.4GHz and -74dBm for 5GHz.
But if I step around the corner, 2 more meters, I get -68dBm for 2.4GHz and -93dBm for 5GHz.
The analyzer shows Turris Omnia is the only router here in the whole 5GHz range, using channel 36. In 2.4GHz there are a few overlapping neighbors, but nothing too bad, using channel 13.
I have the LTE module and antennas installed too, though itās not doing anything yet. Not configured and no SIM inserted.
I did tighten the antenna mounting as instructed, a few were indeed loose. However shouldnāt have anything to do with the coverage.
Is this normal for 5GHz or should I check the antennas or something else?
