Did anyone from Teltonika checked the firmware 7.00?? I find a lot of bugs in only 2 hours....it was not really checked! But now just the problem: I bought a new RUTX11 with firmware 2.6.1 which I updated directly after unboxing to 7.00. After that I try to configure this device for my usage (I will use it in a campervan to enlage the wifi range to my car + build a LTE hotspot for my computer). I'll here only talk about my main problem - not all other bugs: I add my wifi nets 2,4GHz and 5GHz to the "Network/Wireless" and move them up to the first positions at "Network/Interfaces". Also if I don't add the 5GHz AP to this device, I can't get network trafic over the 2,4GHz wifi. If I move the MOB1S1 to top position, I have access to the Internet. I try all also with the ping-command to see if my home-net (ping 192.168.0.250) or google (ping 188.8.131.52) is resonding. No connection over 2,4GHz is possible. If I downgrade the firmware back to 2.6.1, I get a connection over 2,4GHz.
Edit: After 10 Minutes he lost also the connection...unstabile
