Recently just upgraded my Unifi to 300mbps.
But now my desktop is not able to connect sites like Maybank, Hong Leong bank (basically all banking sites) using WiFi
WiFi is able to access youtube, google and etc but not any banking sites.

But I'm able to access banking sites using LAN Cable, only WiFi canot.. Anyone know what's the issue?

Reset your network settings in Windows.

There are many reasons to why this can happen try this step by step;
1. Reboot Unifi router (then see if that works)
2.if doesn't work (IDW); go to Win10 [network&internet] setting > click Network Reset and reboot PC
3. IDW; clear web browser via Settings > reset setting (Chrome)

Do you encounter any error messages?

Try to disable ipv6

Have you tried clearing your browser cache or resetting your router? Also, make sure your WiFi drivers are up to date.

uninstall your wifi driver then install a new one if possible, this one will also soft-reset your wifi adapter

Windows stock driver sometimes just work, but vendor provided driver have better performance and always newer than stock one

Verify the following settings on your computer :-

1. Check the Ethernet DNS entry, is it configured to "Auto" or "Static" ?

2. If the Ethernet DNS is "Auto" (aka DHCP), then set the same for your Wireless Adapter too.

3. If the Ethernet DNS is "Static" or manually configured, then set the same too for the Wireless Adapter.

Alternatively, check the router DNS settings. If the DNS entry in the router manually configured or automatically via DHCP.
You can manually configure the DNS in the router, I would suggest the following DNS address :-

8.8.8.8 --> Google DNS
8.8.4.4 --> Google DNS
1.1.1.1 --> CloudFlare DNS
1.9.1.9 --> TM DNS (not recommended to use due to slow response)

Usually Google's DNS works just fine.

Hope this helps...

your line not secure?
must be something triggering the safety protocol

answer ?

Changing DNS to Google or Cloud Flare will usually work.

Else the problem comes from ISP. You can actually call them up and tell them you cannot access banking sites after upgrade or some updates done by ISP.
