Asus RT-AC66U issues

[Drifter]

I am having issues connecting to my ssh server back home and I think its the Asus router which is causing this. Most of the time everything works normally. but there are times when the ssh connection fails, this started happening recently. I was able to connect remotely till yesterday evening but today I can't.

How can I troubleshoot and confirm that its the router which is causing the issue?

[Speedport modem]----->[AC66U]---->[HP Switch]---->[SSH PC]

Thanks

There are many moving parts to a SSH connection. Consequently, you will need to first understand the exact nature of the failure. I would recommend that you Google "troubleshooting ssh connection" and find the best methodology to determine what exactly went wrong so that you can pursue further troubleshooting.

It came back online today and I was able to connect to my home systems. I checked all logs but no indication of any error.

It could be either the modem or the router, will have to wait till it happens again.

May be I should connect the raspberry pi sitting idle to the modem. When this happens again and and I can connect to the pi, then it means that router is the culprit. If I can't connect to both them its the speedport.

The issue occurred 2 more times and restarting the router was the solution, so I think its time to look for a new router.
