Hi all,
I have an Asus DSL-AC750 modem router.
Each day I have to physically restart it due a strange issue related to dhcp.
During the day at not fixed time, devices get a bad ip from a different subnet than the router so devices aren't reachable anymore.
Instead of something like192.168.0.x the get 192.168.101.1 or similar. This doesn't happen at fixed time, so I find out that issue happened when I try to use smartTV, media server and smartphone not connected to wifi.
Checking router log maybe I found something strange: ICV Error.
These log lines have a timestamp suitable for the begin of the issue.
I can avoid the issue setting manually ip,netmask and gateway but not all devices allow this.
Do you have any hints?
