still happening, btw.
 
@websquadza been battling for the last few weeks with heavy packetloss when uploading anything to Google Drive or Dropbox, haven't raised a ticket because I am aware of issues with my USG (packet loss drops off when plugged into CPE). Was fiddling with settings today, and I set MSS clamping back to auto (was on the... 1432 I think is what you suggested, I don't remember, it was whatever you suggested months ago though), and the issues have all but vanished. Any idea why?
 
Had mine on 1420 and worked fine. Seen now it’s on auto again without issues. Haven’t tested Google or DB, but OneDrive is pretty quick. Line speed. I have noticed that when changing MSS Clamping I had to do a power cycle. Almost like just changing the setting didn’t take effect.

This is quite interesting, 1432 is the correct MSS for a trenched service (1500 bytes - 68), still using it on my USG at home, and @rvanwyk's 1420 should work well on a PPP (1492-68), 1412 would actually be more correct when accounting for some routers' slightly larger ppp overhead of 20 bytes (1480-68).

I think this is more likely down to a unifi firmware update as, in theory, fixed MSS clamping shouldn't be required on a ethernet frame, it should be calculated automatically. So the fact that we had to always set this on UniFi points to it having been some kind of bug. I'll test auto MSS on my USG through the rest of the weekend and confirm.

Did you try AUTO on your USG?

Apologies for the late reply here. Set MTU to auto and everything is running very smoothly (passing the mrs' streaming test). I haven't had much chance to run test other services. But definitely looks like Ubiquity have changed something and Unifi is managing MSS better.

Weird thing is my USG at home has 123 days uptime, so it's not the most recent of updates.

My connection appears to be working again, but it was down since at least 2am this morning.

I would like to know why. Did you monitoring not pick up anything?

This issue was fairly isolated and difficult for monitoring to pick up; a few vlans on a specific access device were not passing traffic - teams cleared this issue and services restored. We will investigate further as well as see what monitoring can be added to prevent this kind of incident again.
 
My connection just dropped again!

Is this just another isolated incident ?
