The router is working on double frequencies, in the settings of the minix box it says it chooses automatically between the two.
I can't see the wifi symbol when I'm in an app, but when it's says no network or just not working I check in the settings an it says disconnect but as soon as I look it connects back on its own.
It's like the box is making fun of me.....
Terribly sorry I had to leave for the rest of the day.
Please try all previous solutions before mine, as they might work, and it will be easier. Thanks for your replying to my questions. So, stop reading here and go up there and try the above suggestions before. If it solves it your time is gained!
You came back?... I am sorry...
Well, if you need my solution, I hope you will be able to follow this walk-through (also with your landlord).
I had my single frequency old router changed for one of these so said flabbergasting new double frequency ones.
Day one of the new router I started getting terrible internet drop offs, and was about to lose my mind. A terrible call centre service my ISP has (don't they all?) always puts me to work on my own to trace all chances before having to struggle with them.
In theory the Minix should choose "automatically" the best network available, true. And logically for the device the best one is apparently the one with the stronger signal, in spite of the frequency.
(Edited 16/5: Before proceeding any further please make sure that setting the network frequency in the wifi settings to 5.0 didn't fix it. In your case it could be that simple.)
The fact the 5.0 Ghz is probably faster and less busy is another subject. The machine chooses the strongest closest signal, as long as it can find the right password to break through.
Now, it happens the 2.4 Ghz, although not allowing such high speeds, reaches (it is so defined by physical characteristics of the signal) a wider range than the 5.0 Ghz one (this is probably the only disadvantage of having 5.0Ghz instead of 2.4), and so the 2.4 Ghz looks to the Minix to be stronger and closer than the lower range 5.0 one, which appears to be at further distance and therefore weaker.
The low speed in your picture 32Mb/s also looks suspicious, I remember those figures from my old 2.4Ghz router in a 100Mb connection.
Because your router is some distance away from the Minix (the same as mine which is about 15 meters away) I was surprised that you mention that you are getting full signal. You shouldn't get full signal for the 5.0 Ghz if the router is one floor bellow. You should get a little less than for the 2.4 Ghz, as both frequencies are in the same router. A little less is still fine.
The problem is the Minix will prioritize to connect to the 2.4 Ghz and gets confused because it should exchange data with the faster/less busy connection:
the 5Ghz one which actually has the same identifiers and password. The same as you can't split the frequencies by eye, as they are conjoint in the same router with the same name and password, you can't tell what the Minix is actually internally doing, as you only see one network in the availability list to choose from.
You will probably need the 2.4 frequency to work, as some devices can't connect to the 5.0 one (I have a mobile phone and some laptops like that). But for an optimal connection the 5.0 Ghz should be the one for the Minix, which is choosing to connect to the 2.4Ghz unaware of our wishes .
Only way I found to go around this:
You have to get to the router network settings (not with the Minix box) and rename differently each of the frequencies and give each one a different password, as if they were two different networks. Now, whatever you do
don't you dare to switch off the 2.4 Ghz! I warned you! You will very likely lose access to your router, especially if your router is set through online connection to the ISP! You would need another internet connection to get back to it (I did that silly mistake, and fortunately had another provider to connect to and proceed!)
Take a note of which is which as you set two separate network names, one for each frequency
with different passwords, and get back to the Minix box.
You should see there now the two different names as available networks, go to settings and make sure it forgets the 2.4 Ghz network. Select the ID of the 5.0Ghz and insert the password. As it no longer has the password to access the 2.4Ghz, Minix will be forced to connect to the 5.0Ghz every time.
In future you can provide the 5.0 Ghz name and password to the devices that recognize both frequencies in their network availability list, and the name and password of the 2.4 Ghz to the devices where the 5.0 name doesn't show as an electable option.
It will work great, as mine does, the aerial signal will look one dash shorter probably, no worries it will fly!
Good luck!
