I have a R300. System version 184.108.40.206.47.
I CAN connect to 5g. I use the iPhone wi-fi settings and connect via that. BUT - at some stage it reverts back to 2.4G. Simply go back to the iPhone settings, turn off wireless. Turn on wireless and we are back at 5G. Later, it goes back to 2.4. I have no idea how long 'later' is as I've not measured it - but it's certainly within the same day.
I have the Country Code correctly set. I don't follow the whole 'balancing' thing but have ticked and unticked things to see if I can 'trick' the R300 to see the iPhone via 5G. I can't.
When I had a ZD1000 I had no issues, but with this R300 I can't set it to perform with 5G. There is one other person using the AP.
I know there's a way to do this but I can't find it and I have read widely. Can someone please tell me what to switch on/off to get this as I want. Thanks.
