Technicolor panoramic router connection hiccups

Hi all,

For the last couple of months I'm experiencing periodic connection hiccups with my Technicolor panoramic router. I work remotely via SSH and there are periodic (once in several minutes) moments when the remote side is not responding. Kids are also complaining that when they play online games, they keep freezing for a couple of seconds.

I've set up a raspberry pi which is connected to the router's ethernet port directly and runs SmokePing. What I'm seeing is that there are periodic packet losses when pinging router's LAN address:

You can see the blue dots appear periodically which mean 1 of 4 ICMP packets have been lost.

The download / upload speeds are good.

The router is connected directly to the cable that comes to the house. But some signal levels look slightly out of spec:

Should I call the technicians to check the signal or the router? It's not very easy to explain this problem to Cox tech support because they prefer to deal with situations when something isn't working at all and preferably can be fixed by rebooting the router
