HI,  this is a follow up to a closed  topic from this forum from 2021.

My Archer 600 randomly Appears offline  (cloud device Offine)  in Tether app - no there is no distortion to internet connection , as devices connected to router via wifi have stable internet connection without a problem.

The issue seems to be related only with router losing connection with cloud;

When I try to access this device via cloud remotely (example : read via Tether  SMS received on sim card in router) most often its offline ; 

Randomly it works correctly ( I havent figured why - once in 20 times I would say)

ONLY after router reset  I can access device remotly for about 5 minutes - as long as I keep connecting via Thether it stays active , the moment I stop it goes offline after about 5 min for good until next reset. 

While I did setup automatic reset every 24h and try to access it only then - this is super incenvenient.  I tried firmware update but it doesnt help . Thinking to replace to another brand, please help ! 

Regards,

Lukas
