Deco X50 Firmware 1.6.1 Frequent Disconnects Using Zscaler

2024-12-11 16:32:31

Tags: #Firmware Update #Network Connectivity

Model: Deco X50

Hardware Version: V1

Firmware Version: 1.6.1

I think this was an issue back in 2023 already where X50s didn't play nicely with Zscaler. This issue appears to have come back with the new Firmware. Admittedly, I'm not sure if 1.5.5 or V1.6.1. I upgraded from V1.4.1.

Zscaler shows that packet data is being sent and received. However, certain resources are not accessible. Primarly MS Teams, and certain websites fail to load. Using traceroute, I saw a lot of timeouts in between hops as well. Though other sites such as DuckDuckGo did not have issues with loading.

I initially thought that it was a DNS issue, but after resetting everything to 8.8.8.8, that didn't seem to fix it.

I had to use the HTTP uboot firmware recovery steps to rollback to v1.2.2 and then upgrade back up to V1.4.1 to fix the issue.

Wondering if anyone else has had similar issues and can recommend a workaround that allows me to upgrade to the latest firmware?

Hi, Thank you very much for the feedback.

After reverting to 1.4.1, did the Zscaler VPN start working properly over Deco?

I didn't receive similar feedback on Deco X50_1.6.1 anymore. If you don't mind, I'd like to follow up on your case via email to consult the engineer for more advice.

Thanks again and best regards.

Yes, reverting to 1.4.1 fixed the issue.

I've sent you an email with the logs that you wanted. I can also confirm the issue started on v1.5.5. The Changelog seems to indicate there were VPN performance fixes in that firmware. Looks like those changes broke zScaler.

Just wanted to post an update for folks that come across this thread. The latest firmware still hasn't fixed the issue, the beta one did not either. 1.4.x does work but with frequent drops, and Youtube videos loading in at 240p, this firmware is a miss.

A quick search of this forum will show that zScaler issues are common among their entire line up. I've decided to stop wasting time and got myself a Ubiquiti Unify Cloud Gateway Ultra, using my X50s in AP mode. I'll slowly migrate these out in favor of some U6 lites.

The Ubiquiti app is hilariously fast after dealing with how slow the Deco app can be. Wondering why I didn't switch sooner...

A Cloud Gateway Ultra and two U6 lite AP is comparable in price to a 3 pack of X50s.

Hi, Nice to see you again.

It is suggested to install the 1.6.4 version here and according to the release notes, It should fix the Zscaler VPN issue:

Deco X50_V1_1.6.4 Boosted Network Stability for Smart Home Devices

Wait for your reply and best regards.
