suddenly no internet connection.. reboot modem and router also same. i notice link led at modem currently red? live chat also "something went wrong"... anyone else?

semenyih area here..

Hi and morning all..

If anyone experience this -> while all devices connected to router wirelessly and also wired, a new device failed to connect WIFI to the router, it says "IP Configuration Failed". Then shutdown the router and modem for 10 minutes and turn it back on. Now all device can not connect neither through WIFI or LAN.

However, it is possible to get connected back by using static IP address.

But, why is suddenly like that.

I still using TM Router and Modem.

for info..TM Router = Dir 850L

Also believe the same thing.. Dhcp server seems not running... Although enabled in setting

Just chat with Live chat... Usual restart the router.. Last step, they sent a technician here.. Let see later what goes wrong

Also I notice tr ip address is not there in main configuration page of router.. I believe there is some ip address there before... Related?
