I have a RUT240 thats amost 2 years old. It has been in the same location since purchase, indoors next to a window. 5 days ago it started disconnected and reconnected from the Mobile network. I know this because i have some smart plugs and p2p cameras that notify me when they become offline. Until 5 days ago, it had been rock solid (apart from the occasional power failures).
I updated the firmware from RUT2XX_R_00.01.14.1 (legacy) to RUT2XX_R_00.01.14.5 (legacy) and then to RUT2_R_00.07.01.4.
Also switch from 3G+4G to 4G only.
Didnt really help
Apart from the disconnects i dont see any other issues except one more. After the Mobile network reconnects DHCP leases ip to the lan devices even though the DHCP lease duration is 12 hours, but i guess that could be how it works.
Apart from that the device is responsive, i can navigate, install packages, no issues at all.
What i want to ask is this: Are these constant disconnects a sign of hardware failure? Or is it from the Provider? How can i check this apart from switching out sim for a different provider or moving the device to a different location?
