A34 Tethering issue

[Members_U7JIH0Y]

I have an A34 5G with Android 15, One UI 7 and an A16 5G with the same android version that was updated a few days ago. I am on vacation and I have three laptops that get internet access from them. All three laptops have problems accessing the internet with A34. At some random moments web pages are not loading. I click a link and tries to load for ages. I try to watch youtube videos and at random points the try to load with no success. A few seconds or a few minutes later video or pages loads and behaves like nothing happened. The problems appear with both Firefox and Chrome.  When the laptops get access from the A16, I have no problem. Both the A34 and the A16 have sim from the same Carrier, they are next to each other with unlimited data program. All the above make me think that something is wrong with A34's tethering but what can it be? On last year's vacations I had no issues. Is it android 15 that does something wrong?

Better if using Wf-Fi connection if possible

You're not alone, others have reported similar tethering issues with the Galaxy A34 on Android 15 / One UI 7. Since your A16 5G works fine with the same SIM and network, the issue likely lies with the A34's tethering implementation after the update.

Here are a few things you can try:

1. Reset network settings on the A34:
Go to Settings > General Management > Reset > Reset network settings.

2. Change the AP Band in Mobile Hotspot settings:
Try switching between 2.4GHz and 5GHz to see which is more stable.

3. Disable Battery Optimization for the hotspot:
Go to Settings > Apps > Mobile Hotspot > Battery > Unrestricted.

4. Manually set DNS on your laptop to 8.8.8.8 and 1.1.1.1. This can help if DNS resolution is part of the delay.

5. Toggle Airplane Mode, restart the A34, and try again.

Let me know if these steps work
