Since installing 17A264c have been experincing a bizzare networking issue on my late 2013 MBP ...
Regardless of what browser I use (tested and verified that same problem occurs in Safari, Firefox, Opera, Chrome), at seemingly completely random times all my network activity just stalls. Resources go from loading in a a second to timing out even if the same resource was loaded seconds prior.
Connection to the router remains stable (however I did test while connected directly to modem and same probem occurs), but the in/out activity simply stalls. Number of packets going in and out drops to 0-2. This effects both WAN and LAN connections. Now probably 75-80% of the time is spent on waiting for the stalling to stop. Interesting thing is that even while everything appears to be completely stalled, if I ping an address like 8.8.8.8, connection to it remains a stable 1.2-1.8ms as always with no packet loss.
Same issue occurs both via WiFi and ethernet. All my other devices are running latest beta versions of iOS, tvOS and watchOS - none share the problem.
Has anyone else experienced this issue and can advise as to what may be causing it? I'm at a dead end here ...
