And this brings back the topic of transparency. Such massive issue should be proactively communicated once detected.
We look like fools (at best) in front of customers. Peplink means reliability on the WAN, this is the opposite of it.
Anyone can make a mistake, we can handle that if informed before customer’s production is impacted. We were looking everywhere for an issue…
Same for the LAN extra latency introduced by the internal switch 
I am not aware of this issue. What is happening?
an issue on the internal switch creates some loops and latency goes through the roof. Very hard to detect for us as only the LAN users are impacted.
Should be solved now.
This was another issue we saw with QOS enabled. After a random amount of time we had several sites report that latency was awful for them accessing the internet. We would test from the device to the internet and see no issue but if we pinged anything on the LAN the latency would be anywhere from 50-2000ms with packet loss.
We deployed 50 devices and saw it on almost all of them, removed QOS and rebooted and the issue hasn’t recurred. The special build we tested with for the random crash seemed to fix the crash but the 2 sites we tested with had the latency issue recur. We have since disabled QOS and have not seen the issue since.
Re creating this though is difficult as it took a couple of week to appear on one site and nearly a month on the other.
Update:
Peplink sent me a firmware (8.5.1s095 build 5810) that addresses the issues with the WAN2 interface.
I deployed this firmware 10 days ago, and it looks like the WAN2 issues have been solved.
I am just waiting for the QoS fixes. I will post an update once I receive the new firmware that addresses QoS specific issues.
Cheers!
Update:
My routers have been stable for 25 days since the upgrade to firmware (8.5.1s095 build 5810). No issues.
I am still waiting for the new firmware to address the QoS issues. Engineering sent me an update saying the latest version is going through tests, and I will see the new firmware soon.
8.5.2 it will be your hope… It is coming…
29089 - [RC 1] [System] Fixed a system stability issue caused
by QoS
(Fixed in: 8.5.1s111, 8.5.1s084, 8.5.1s039, 8.4.1s140)
Engineering asked me to test 8.5.2RC1, which fixes the QoS issues. However, the WAN2 fixes were not included in the new firmware.
So I am stuck with the version they provided to me until there is a version that addresses the QoS and WAN2 issues.
Had a spontaneous reboot when connecting to the ISP via “WAN1” port and output to 4 laptops via the 1,2,3,4 ports.
I thought i did something wrong, but i think it was my old firmware 8.5.1.
I’ve now upgraded to 8.5.2 - hopefully this will fix the issue - it was a close call at a livestream event
P.S
Had to do it via “Manual” fw upgrade.
Is everyone confident this is solved?
My B One 5G is on 8.5.2 build 5862, can I trust my WAN 2 port?
Is it safe to use QoS if need be?
Haven’t been able to fully stress test the new firmware yet. But on 8.5.1, I ran into stability issues almost immediately—router rebooted within 20 minutes of connecting 1 WAN, 1 SIM, and 4 LAN devices simultaneously.
Would appreciate if someone can run a 2–3 hour stress test with all LAN ports active and report back with the 8.5.2 fw.
From my experience, firmware version 8.5.2 build 5862 on the B One 5G resolved the WAN2 issue; however, QoS caused the devices to crash.
Here is the latest:
WAN 2 and QoS issues: Both issues were resolved for me only after I upgraded my routers to the following firmwares:
B One 5G - 8.5.2s001 build 5865
B One Plus - 8.5.2 build 5862
Both models have been performing solidly for two months.
Now, for the issue that was driving me nuts:
Balance 20X crashing randomly due to QoS issues - the issue was resolved only with the firmware 8.5.2s067 build 5596.
The 20Xs have been running for 18 days without any further issues.
I have not noticed issues with the LAN ports.
Cheers!
Interesting replies, appreciated.
I’m not using WAN2 or QoS, and generally have found my B One 5G to be stable and reliable over the last year or so it’s been in daily use. Just one user, but I do use it a lot! I’m pulling plenty of traffic over Wifi WAN or 5G WAN all the time. Mostly to one computer at a time and my phone, but there’s plenty of IOT like devices, lighting controllers, weather station, solar/lithium power system monitor, etc.
