Internet Speed

​1. Reset Network Settings

​This is the "gold standard" for fixing connectivity issues. It clears saved Wi-Fi networks and Bluetooth pairings, forcing the phone to create fresh connections.

​Go to Settings > General Management. ​Tap Reset > Reset Wi-Fi and Bluetooth settings. ​Tap Reset settings to confirm. ​2. Disable "Switch to Mobile Data" (Intelligent Wi-Fi)

​Sometimes the phone constantly checks for a "better" connection, which causes lag or speed drops.

​Go to Settings > Connections > Wi-Fi. ​Tap the three dots (or Intelligent Wi-Fi) in the top right. ​Toggle off Switch to mobile data. ​Also, try toggling Wi-Fi power saving mode off to see if speeds improve. ​3. Change the Phone's DNS

​Standard ISP DNS servers can be slow. Switching to Google or Cloudflare can often stabilize speeds.

​Go to Settings > Connections > More connection settings. ​Tap Private DNS. ​Select Private DNS provider hostname and enter dns.google or 1dot1dot1dot1.cloudflare-dns.com. ​4. Router Side: Separate 2.4GHz and 5GHz/6GHz

​The S25 Ultra supports Wi-Fi 7. If your router uses "Smart Connect" (merging all bands into one name), the phone might be jumping to the slower 2.4GHz band.

​Solution: Log into your router and give the 5GHz or 6GHz band a different name (e.g., "Home_5G"). Connect your S25 Ultra specifically to that one.

Thank you for sharing your experience with the internet speed on your Galaxy S25 Ultra. We understand how important it is to have a fast and reliable connection, and we apologize for the inconvenience you've been facing with Wi-Fi performance.

There are several factors that can affect Wi-Fi speeds, and we recommend trying the following troubleshooting steps to improve your connection:

1. Check Router Settings:
2. Ensure your router is capable of delivering high-speed internet (e.g., Wi-Fi 6 or 5 GHz band).
3. Try restarting your router to clear any temporary issues.

Move Closer to the Router: If possible, move closer to the Wi-Fi router to reduce interference and signal loss.
Forget and Reconnect to the Network: Go to Settings > Connections > Wi-Fi, select your network, and tap Forget. Then reconnect by entering the Wi-Fi password again.
Check for Interference: Other electronic devices or appliances (microwaves, cordless phones, etc.) could be causing interference. Try changing the Wi-Fi channel in the router settings.
Test on Different Networks: If possible, test your phone’s internet speed on a different Wi-Fi network (such as at a friend's house or public Wi-Fi) to see if the issue persists.
Software Update: Ensure your device is running the latest software by going to Settings > Software update > Download and install.
Reset Network Settings: If the issue continues, you can reset your network settings by going to Settings > General management > Reset > Reset network settings. Please note that this will remove saved Wi-Fi networks and Bluetooth pairings. If these steps do not improve your Wi-Fi speed, we recommend visiting an authorized Samsung Service Center to have your device thoroughly checked.
