@Sunshine 

many thanks Sunshine ☀️ 

The router appeared to  reconnect to the security cams after a 2 hr lapse. 
I just need to try and connect remotely with it ( presume that isn't possible if it's offline ? ) 

Do you think I need to worry about static IPs etc ?

( when I set it up initially, it was a breeze and worked without any hitches for 3 weeks but then went offline on Monday night for 2 consecutive weeks ) ...or maybe my tp link extender is interfering with it perhaps? I will keep an eye on it . 

Hi @Sunshine 

yes I have bound the device on tether and access was limited since the wifi was off . 

It it because the address is not static ( since it is a mobile sim ) ?

Thanks

  @Pattie-UK so initially after nearly a month of continuous uninterrupted connection, my newly set up MR 200 is disconnecting weekly and now daily  for 2-12 hours at a time which is useless for the purpose it was purchased for - security cam monitoring. 

When checking, the firmware update says up todate and signal strength 75%.

I looked at the logs - there were 60 pages all with the same date but downloading only showed the most recent page . 
 

I have set it to 4G only using band 1, 20, 40 but it disconnected shortly afterwards with a drop in signal strength,  so I set it at band 1 and 20 and it appeared to reconnect with a signal strength of 75%. 
 

I hoped this would solve my issue but it has gone offline again :( 

I attach the screen shots of the log history and the part when it went offline again but unfortunately missed the first minute however also attach a similar episode from earlier in the day .
