I have a RUT900 that keeps falling off the mobile network. It has good connection and can find the provider. But every 5 min, that connection loses and I have to re-enter and re-enable the pin code.
I've been having trouble now that it just connected for 2-5 seconds and then it jumps off again. Have used the setup wizard.
I'm running firmware RUT9XX_R_00.05.04.
