They all use different SSID's. I have 4 different ones. 2 for the router and 2 for the extender. its odd because I have a shield upstairs and another one in the basement and they never have this problem. The minix is in the living room. The router is upstairs. Just now I couldn't get it work despite it saying it was connected. I unplugged it and plugged it back in and it works. no idea why.
Well, all I can say is that I had to make forget the connection to the 2.4Ghz network in my U1 for things to work. Differently from the U9-H where you can set it to always connect to the 5 Ghz exclusively, the U1 doesn't have that setting. To make things worse my ISP router had one single SSID to connect both frequecies, and it could only be set over an online connection to the ISP. All these was new to me, as I was used to acccess routers by computer and set them on sight, so between losing internet connection completely and having to set this router over a different ISP internet connection, and finding out what was wrong with my always perfect U1 to be quiting on me, here is what I did:
I gave different names and passwords to each of the frequencies so I could easily identify and choose precisely in the U1 WiFi settings which frequency to connect to.
There is something you should care about. The 2.4 one reaches a wider range, and so the aerial signal is better on this frequency, especially noticed when the router is far from the Minix box, because the U1 selects the frequency automatically it normally tries the connection to this one preferably, and then is doesn't carry on maybe because the data flows quicker in the other (apparently weaker) frequency of the same router.
Somehow and beyond my technical knowledge and comprehension this affects the U1 performance to the point of it becoming totally stalled. Even when I make the oposite and tell it to forget the 5Ghz network and send it to connect to the 2.4 Ghz it refuses to work properly, which is hard to understand as all other devices that are not 5Ghz capable work in the 2.4 frequency to perfection.
When you deny the existence of the 2.4 Ghz frequency
(now network - edited: actually the network remains the same as you can transfer data all over the devices connected to any of the frequencies) to the U1 and connect it to the 5Ghz only you will regain the U1 to its best. Occasionally it will try to connect to the 2.4 Ghz on its own and that is why you shouldn't supply the password to allow it to perform that connection, it will then follow to choose automatically the connection that is password allowed. When this happens you should go back to the WiFi settings and set it to forget the 2.4 again, as these connection tryouts are time consuming.
I hope you can do something out of that, changing what has to be changed according to the stuff you are including. So far this was the only way I could achieve to get my faithful U1 back in track since the day I got that double frequences router. Please let us know.
