UniFi wifi connection works poorly on certain apps in S22 Ultra

[lacrimosa93]

Hello,

I bought my S22 ultra and got it around April 2022.

I am using TM Unifi wifi connection with the device, and found that for certain apps the connection are very poor. (For example it works completely fine with Facebook app but can't connect on Grab app). I can confirm that the Grab app is not down as it immediately connected after I switch to mobile data.

I have also tested with the same app and same unifi connection, but on other android devices, the Grab app connects just fine. 

So anyone having the same experience? is it something got to do with my Unifi, or on the phone itself?

Thanks!

I have the same issue with different apps but only on 5GHz. No issues on 2.4

Has this issue been resolved? I'm facing the same issues with my S23 Ultra too.

Galaxy Store won't work on my UNIFI WIFI but once switched to mobile, it works.

This is exactly my issue as well. My Wi-Fi works fine on every other Wi-Fi network except UniFi. I have to turn off Wi-Fi and switch to Mobile Data to get all my updates.

I'm facing the same problem. When I make speedtest with other android, the result show huge difference between the device. My S22 got below 10mbps. The other device got more than 50mbps and I'm using unifi 300mbps.
