I’m having an issue with my iPhone 17 Pro, which I just bought in 2026.
Long story short, I live in Indonesia and use Biznet Wi-Fi, with speeds of 100 Mbps on the 2.4 GHz network and 300 Mbps on the 5 GHz network.
After using it for a few days, the Wi-Fi speed suddenly drops to around 20 Mbps. I’ve tested it on Biznet Wi-Fi at three different houses belonging to my friends, and the speed still gets stuck at around 20 Mbps.
Sometimes, the Wi-Fi speed drops dramatically to as low as 0.5–5 Mbps, which is extremely strange. This only lasts for a few seconds before the speed returns to normal, even though the Wi-Fi signal remains full (all 4 bars).
The only way to restore the normal speed is to restart my iPhone or reset the network settings. However, after a few days, the same issue comes back. This keeps happening over and over again, with no permanent solution.
I’ve also seen many people reporting similar issues on forums. I’m not using a VPN or changing any special settings. I’m just using my iPhone normally for everyday activities.
One thing worth mentioning is that I transferred my data from my old iPhone 13 when I first set up this iPhone 17 Pro.
How can I fix this? Please help me. This issue is extremely frustrating.
Do I really need to factory reset my iPhone, even though it’s brand new? I’m considering setting it up as a new iPhone and restoring my data from iCloud only, rather than transferring everything directly from my old iPhone.
I would really appreciate any advice or a permanent solution to this problem.
For comparison, the other phones in my household have no issues whatsoever when connected to our home Biznet Wi-Fi:
- My father's phone: Samsung Galaxy S23 FE
- My mother's phone: Samsung (an older model from around 2015)
- My younger sibling's phone: iPhone 15
All of these devices work perfectly fine on the same Biznet Wi-Fi network, with no speed drops or connectivity issues. The problem only seems to affect my iPhone 17 Pro.
PLEASE HELP ME GOD !!!!!!
