That's tonight's task. Been on phone with ISP for hours because, of course, since we can't reproduce with a single laptop connected to their modem - not their problem even though the packet loss clearly starts at their x.x.x.1 gateway. Trying to get them to understand that there's clearly some 'trigger' 5-30 minutes after…

We did. Didn't matter.

Gotcha. We switched to the TCP connectivity check instead of ICMP on WAN1, no change. Also had Proxy ARP disabled on the WAN side as well.
-
Sorry - confused what a ping check from the WAN interface would do or cause in relation to this? I mean we have the connectivity check enabled since we have LTE backup on WAN2. But we've disconnected the LTE backup since they've throttled us now. Disabling the Connetivity Check on WAN1 doesn't do anything in terms of the…

That's what I was leaning towards. Late yesterday we left the Zyxel on LTE backup (WAN2) and connected a laptop directly to the EN2251 with pingplotter going. Now, clearly not an apples to apples test since the laptop just had a YouTube HD test playing, not everything else. But still… Came in this morning - no packet loss.…

No indication of failover on the Zyxel. Because SOME pings are making it out (the whole on then off then back on cycle we've seen) it never exceeds the timeout threshold that triggers a failover. But we've pulled the WAN2 connection to prevent any attempt to failover and we still see the issue happening. I think the next…

That's what we're doing. Laptop is fine so far. Clearly an issue between this model modem and our ATP200. I'm going to try to get logged into it to see if there's anything we might be able to set in the modem to avoid the issue. Used to be you coudl get to Spectrum/Charter modems at 192.168.100.1 even in bridged mode but……

Switch in between made no difference. We're running a ping test with a dedicated laptop now with the office on LTE backup
-
Well we're not losing half the speed - we're losing half the packets on and off (the red bars in the graph above). The ATP200 shows the WAN port negotiated at 1000M/Full like it should be. Just for kicks I'm about to throw a mini gigabit switch in between them to see what happens. (UPDATE - Didn't help. Worked OK for 20…

We're seeing the same thing on all of our devices USG and ATP that have the latest firmware. We're going to flip to email for now....

But Cooldia is correct about the session disconnect. If that box isn't checked, when WAN1 comes back up and it auto switches back, any existing connections will remain on WAN2, some of which can stay up a loooooong time. So it seems like it didn't fall back. We always check that box unless a client is using VoIP phones or…

Sent - if you need anything else, just let me know!

We've switched over to Google Authenticator (we actually use Authy) for admin access for this very reason.

Yeah - we don't even try SSL inspection on phones. We limit it to select desktops we know have the certificate installed properly. So these aren't coming from a phone.
