Nothing immediately obvious from that lot I'm afraid. Looks like you recently restarted the hub (because the pre-RS error count is low, and the hub clears the error counters when power-cycled), but the 20 post-RS errors on channel 2 don't look good. A post-RS error is an error that can't be fixed by the hub's error correction software, and if that number is rising, then that could explain the latency issues. Make sure the hub stays switched on overnight, and repost the stats when you've got a 24 hour BQM, as that'll mean we can see what's happening to the errors.
I'm focusing on the cable connection as that's easiest to check; If the BQM comes back "clean" and the hub stats are similar to those just posted then we might need to look at the wifi settings, but normally latency problems are cable rather than wifi. There is a small latency overhead added when you game over wireless, but if all is working properly that shouldn't cause any problems.
