@Lada_X50 I've just installed a Deco X50. Not had any issues with Zscaler.

I'm not using HomeShield, do you have to use it?

  @Pezky - Could you please advise how to switch off HomeShield? As far as I understand even if HomeShield subsription is not activated, the HomeShield is still on sending DNS requests to Avira.

Hi David

Question:

So I wonder when Deco X50 is on router mode, if the laptop is wired into the main Deco, are you able to get a stable connection.

Answer:

No, if the laptop is using ZSCALER VPN and Proxy. Other laptos without ZSCALER VPN and Proxy have the speed decreased (ping increased) compare to using other routers.

Question:

Please also refer to this link to change the WAN DNS to 8.8.8.8/8.8.4.4 to see whether it helped:How to change DNS server settings on my Deco

Answer:

Yes, I am using Google DNS servers.

Question:

By the way, when you are available, could you please help me test when both C9 and X50 are on the wireless router mode(ISP--Archer C9---Deco X50), are you able to get a stable VPN connection over Deco.

Answer:

Please let me know, when you would be avaiable and how would you like to analyze the issue. I will do my best to assist.

Summary:

I' m 99% sure that the issue is related to HomeShield firewall on Deco. Any other router including Tp-link Archer C9 is working fine and Deco X50 in access point mode is working fine as well. Unfortunately HomeShield firewall has no options for configuration. I find that hard to believe for a product, which costs 270 EUR.

  @DecoX20 hi have Deco X20 Zscaler VPN Is Not Working 

we have other netgear router it working Fine. Please  Help

  @JiteshKeny 

I had TP-link support connected to my network using Teamviewer uploading debugging firmware and modifying the settings to enable working it with Zscaler.

They have also said new firmware will be provided via TP-link support channel, once the issue is resolved in new firmware.

Hi guys,

I have bought last week the X50, and it worked fine and all until I had to connect to work .. using ZScaler.

Do you have any idea if this problem will be fixed soon or do I have to return it and find another brand that is compatible with ZScaler?

From what I can see in the comments this is not their only model that is not working with ZScaler.

Thanks

Hi @David-TP , I guess there is no status yet about the firmware, right?

Personally I'm not ok with solution for each customer separately (teamview + call), especially if it has to be on the work laptop on which there is ZScaler installed. I would prefer a general solution that works for everyone. At the moment I use the deco as an access point, but it's not what it was bought for .

Hello,  I have same issue. 

Which setting are needed to solve ZScaler issue on work laptop.

All other Devices works fine.

Currently I use Router Mode!

Why is AP Mode better?
