It is 10PM but I have tested this from 7PM today. At someone else's place.
PC with network cable under speedtest.net gets a 94/20.
Cellphone gets a 33/20 under the 5Ghz band, the other band I get 20/20. This same cellphone at my home, with 2Degrees (with their Fritzbox) gets up to a 94/20. I also walked up so I was 1.5m from the router physically. Using the WiFi Analyser app it shows the signal was 55dBm.
The My Republic router is a TP Link Archer C2.
Any thoughts? Cheers
