Hello,

Please confirm what do you mean by router restarting on a regular basis, are all the LEDs turn off then on automatically and the internet on it will temporarily down then recover?

May I have your network layout, how is the C1200 connected in your network? Was it working fine before and started to restart just after you upgraded the internet bandwidth to 100Mbps?

How many devices are connected to C1200, wired, and wirelessly?

Is there any other setting or feature in your network that may cause this restart issue, or is there any special operation/activity in your network that causes the C1200 to restart?

Good day~

Hi Kevin,

1. Yes, all the lights go off, power light starts to blink and the router restarts. During this process there is no internet.

2. This entire process takes around 2-3 minutes.

3. For network layout I am using it as a router not as an access point, there are 7 wireless devices connected and there is one wifi extender TL-WA850RE.

4. I do not see any such feature in the router or in the network for restart as I tried another router D-Link for a day with the same connection type and all the devices connected and it works perfectly fine without any issue.

Hope this answers all your queries.
