Thanks for posting, I did respond to your other posts on another thread earlier today so I'll post the same here:
The trace looks perfectly normal but the ping does show packet loss. The thread you've linked is to do with suspected issues with the SH2 firmware causing drops from games, we don't have a timeline for this at present I'm afraid but it is being worked on. This will only cause drop outs however, not any issues with latency and we've not seen any evidence of packet loss (other than the 100% when it drops completely of course)
This issue is eliminated when the hub is put in modem mode. If you've not tried this already could you give that a go?
I think it best we keep this to one thread to avoid any confusion so could you post any reply here rather than on the other one?
It's a small test to see if there is any problems also in modem mode, if none, then it may be with the firewall part of your Shub being the culprit and from there it might be easier to track down the problem.
