Web Guard problems with WiFi

Chat TIP:

go to Web Guard and tick Block Trackers ON.

That was the solution I have been looking for.
thanx Trend Micro Support Service.

Enabling the "Block Trackers" option in Web Guard resolved my Wi-Fi connectivity issues. It's great to see the community helping each other troubleshoot effectively. Kudos to Trend Micro Support for the helpful advice!
 

I wish it was consistent.
But NO.
Now using my iPad with Web Guard OFF.

Hello,

Make sure you don’t have any other VPN apps on your mobile phone and that Trend Micro Mobile Security is updated. You can follow this guide for Web Guard.: Web Guard issues in Mobile Security on iPhone or iPad | Trend Micro Help Center

Keeps websites from following your online activity, which protects your privacy. Reduces the amount of data loaded from trackers, which can speed up page loading times.

Hello,

You’re correct. The issue could indeed be caused by conflicts between Web guard VPN and other network configurations or VPN apps. We recommend checking that no other VPNs or security profiles are active on the device, as having multiple VPNs running simultaneously can cause network interruptions or dropped connections.

If it only works with Web Guard off, it might be a DNS or VPN profile conflict rather than the Block Trackers setting itself. Have you checked whether iCloud Private Relay or another DNS filtering app is enabled at the same time?

Hi,

Thanks for pointing that out — you're correct. If everything works only when Web Guard is off, it usually means there’s another VPN, DNS filter, or network profile on the device causing the conflict, not the Block Trackers setting itself.

On iOS/iPadOS, Web Guard works through a local VPN. If another VPN app, DNS filtering tool, or features like iCloud Private Relay are active at the same time, they can interfere with Web Guard and lead to slow or unstable connections.

I have updated my WiFi recently. And every time I sign on to something, the program says that my new WiFi is not safe? How to update so it is on the same page?

Hi,

Trend Micro Mobile Security checks your Wi‑Fi network for the following:

• Weak Wi‑Fi encryption (ex: WEP or no password)
• Weak router password
• Public/unknown network risks
• Unsecure router settings (ex: open ports or outdated firmware)

If any of these are detected, it will show a warning.

Here are some tips on how to fix it: 

• Make sure you use WPA3 or WPA2 encryption 
• Change your Wi-Fi password to a strong one
• Update your router firmware 
• Restart your router 
• Rescan the Wi-Fi using Trend Micro Mobile Security
