What could cause my ping to look like
--- 192.168.0.1 ping statistics ---
121 packets transmitted, 118 packets received, 2.5% packet loss
round-trip min/avg/max/stddev = 2.689/154.201/1128.263/193.576 ms
(Note: the ping stats and the image are from different ping ... sessions? Basically they don't summarise the same set of pings.)
As you can see, my ping is horribly inconsistent, with a minimum ping of 2.689, which is acceptable, but a maximum of 1128.263, which is definitely not acceptable for a ping to one's own router.
I have already tried restarting the router, even switching to a different router, which leads me to believe it's some kind of interference (it may not be)—but it's weird because the pings look the same from anywhere in my home! Even right next to the router.
All wireless computers show similarly horrible ping times, but all ethernet pings are consistently less than a millisecond.
The router is a Sky SR102, firmware version 2.91.2110.R and DSL firmware version A2pv6F039m1.d24m.

I don't think it's the router neglecting ICMP, online games are suffering (which is what prompted me to start investigating my network in the first place) and also using traceroute with different protocols (ICMP, GRE, UDP) all show the same pings.
Neither of the routers support 5GHz.
The wireless connection to my own router is disgusting:

I get similar pings on all the wifi-connected devices in this house, even right next to the router (a Sky SR102 with firmware 2.91.2110.R).
Ethernet devices have normal ping times.
How do I fix this so that all wifi-connected devices have low consistent pings?
