OpenWrt on Ubiquiti UniFi-AC-LITE and trouble visiting Yahoo website

Hi all,

I hope someone knows what's going on.
I just bought a UniFi-AC-LITE and installed OpenWrt 19.07.6.
The process was straight forward and took less than 30 minutes.
However, after the installation, something weird happened. Everything seems working fine with the internet EXCEPT yahoo website. I can't access yahoo website.

if I type:, browser redirects automatically to Canada subdomain: (I am in Canada). Then it stucks, after loading a long time,few minutes, it's display a text only site and google ads banner and no formatting.

If I type:
I'll get below error message right away:

Browser Error message:

This site can’t be reached took too long to respond.


Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics

The weird thing is: I have no problem access all other sites! I didn't put any filter for yahoo. Is it yahoo site is imcompatile with something in UI AC LITE + Open WRT?

I have Open WRT on TPLINK C7 wireless router and had no issues.

Basic hardware config:

  • I have a DSL modem with ethernet LAN ports, and I connected UniFi-AC-LITE to one of DSL modem LAN port.
  • I edit LAN interface and use modem's IP on IPv4 gateway, and Use custom DNS servers
  • Wifi is set as Access Point.
  • I tried disalbing the firewall and it didn't help with Yahoo problem. I don't think it's firewall related since I have no problems with other sites.

System log:

Some strange kernal log:

Apart from that, if you connect directly on the lan ports of the DSL modem/router it works fine?
Also the C7 is also a dumbAP, just like the UAP-AC-Lite?

So I changed back to stock firmware and then installed the older version OPENWRT 19.07.5. Now I can access Yahoo site. WIFI speed seems better too on 19.07.5. When I was on 19.07.6, WIFI was very slugglish at 8Mbps.(max 15Mbps). Now I can get 15Mbps on 19.07.5. Maybe 19.07.6 is buggy or installation was corrupted. I don't know. But changing to older version fixed the problem.

BTW: When I first installed 19.07.6, there's a XML error message right after logging in to web Gui.

@kyle_L, welcome to the community!

Be sure to upgrade dnsmasq. There is a security issue.
