Welcome to our forums and thank you for getting in touch. Apologies for the delay in getting back to you, we've been quite busy recently! It's a shame that you've been experiencing high ping on your wireless connection, I'd be happy to take a look at this for you.
I can see that our online troubleshooting flagged an issue with your wifi connections and in-home setup. Were any recommendations made following this? Have you been able to resolve the increased latency since your post?
As you've advised that the ethernet connection is fine, it would suggest that the issue lies with the wireless signal only. Taking a look at the backend of your services, I've not been able to identify any obvious cause for this degradation. Have you ensured that there are no devices too close to your hub which may be causing interference?
Have you noticed whether this happens more at certain times of day or if you're in a particular room?
