@Sunshine HI, One question: is it normal for the MR500 to switch every 15/20 seconds from 4G to 4G+? It does this every day at all hours and the log file is endless until the automatic restart at 03:00.

@Ekkoh Hi, I have changed my ISP (it only works in band 3/20) for 15 days and I have not had disconnection problems (automatic restart every night). With my previous ISP (band 3/20/28) I had several disconnections throughout the day that were solved with automatic restart at night. I was bored (trying various setups since January) since I mainly use it for home surveillance at my 2nd residence. I decided to change ISP and I've had no disconnections for 15 days. The only problem is that it changes every 15/20 seconds from 4G to 4G+. Try another ISP to verify..... Regards

Hi, the changing between 4G and 4G+ is usually related to the base station as well, if the internet is stable now and speed is acceptable, please don't worry.
