Assuming Speedport.ip is your own router (which it very likely is as that's the first hop) I would recommend rebooting that and seeing if it fixes things. I only mention that because although the average is ~5ms which is respectable (still higher than I'd expect, but meh) on both of them it has a "worst" ping of 209ms which is insanely high for something on your own local network.

The rest of the route seems to have a decent average too, but a high "worst" (so a spike), but you need to remove the initial spike in your own hardware first as that could be skewing the rest of the results.

Also if you have a second computer in the house, try the route tracing on that and see if you get that occasional spike on your own router (might be just related to individual computer rather than the router itself)
