Galaxy S25 5G & Wi-Fi Issues – Signal Repair in Vancouver

The Samsung Galaxy S25 series offers enhanced performance, improved camera capabilities, and new AI features. However, many users have reported issues with 5G and Wi-Fi, especially with the Galaxy S25 Edge. Frequent signal drops, slow downloads, and unreliable connectivity are common complaints.

If you’re using the Galaxy S25 Edge and experiencing these issues, this blog explains the causes and available repair options. Whether you’re in Vancouver or nearby cities, understanding these problems can help you decide whether a fix is possible through settings or if professional repair is needed.

Standard 5G and Wi-Fi Complaints on Galaxy S25 Edge

Customers have reported several recurring issues since the S25 Edge was released:

1. Wi-Fi disconnects automatically after a few minutes
2. 5G signal drops when switching between apps
3. The phone shows full bars, but there is no internet access.
4. Wi-Fi works, but speed is unusually slow
5. 5G drains battery quickly even in standby

If you’re facing any of these, you’re not alone. Repair shops across Vancouver are increasingly encountering these issues.

1. Weak Antenna Placement in the Slim Body

The Galaxy S25 Edge is thinner than previous models, which leaves less space for antenna modules. With limited internal space, the antennas for Wi-Fi and 5G may be smaller or placed closer to heat-generating components, such as the battery or processor.

Result:
Signal drops occur more often, mainly:

1. In low-signal areas
2. When using a case with metal or thick materials
3. During charging or high-performance tasks (gaming, hotspot)

2. Software Glitches After One UI Updates

Samsung has released multiple firmware updates for the S25 series, and some of these have introduced bugs affecting:

1. Network switching between 4G/5G
2. Wi-Fi handoffs between bands (2.4 GHz and 5 GHz)
3. VPN or private DNS settings interfering with signals

Temporary fixes:

Reset network settings:
Go to Settings > General Management > Reset > Reset Network Settings.

Disable private DNS:
Settings > Connections > More connection settings > Private DNS > Off

If these don’t help, the problem may be hardware-related

3. 5G Overheating = Signal Throttling

Many users report the S25 Edge gets warm quickly while using 5G. This causes the phone’s system to throttle performance—including network signals.

Symptoms:

1. 5G drops and switches to LTE or 3G during video streaming
2. Wi-Fi disconnects when the phone overheats.
3. Lag while downloading a large file.s

If the device frequently overheats, internal damage may affect its connectivity components—especially the antenna cable, signal amplifier IC, or power management chip.

This type of issue is often observed in locations in Vancouver, such as Samsung Galaxy S25 Edge repair locations, after just a few months of use.

4. Router or Network Interference

Not all issues are caused by the phone itself. Sometimes the environment, router, or SIM card can affect signal quality.

Troubleshooting checklist:

1. Test Wi-Fi on another phone in the same spot
2. Try using mobile data with a different SIM.
3. Switch your router channel (especially if multiple devices are connected)

Still not working? Then internal hardware might be the issue.

5. Physical Damage or Loose Connections Inside the Phone

A drop—even one with no visible cracks—can loosen internal components. The Galaxy S25 Edge uses a flex cable to connect the antenna module to the motherboard. If this cable is slightly loose or damaged, you’ll experience:

1. Random loss of 5G or Wi-Fi
2. Weak signals even near a router or tower
3. Bluetooth issues (same module)

This is not something that can be fixed through settings. You’ll need a proper inspection at a shop that offers Cell Phone Repair in Vancouver with board-level diagnostic tools.

How a Repair Shop Can Help

If none of the basic fixes work, it’s time to get your phone checked by professionals. Here’s what a proper diagnosis includes:

Step 1: Network Signal Testing

Shops use signal simulation tools to test your device’s antenna strength under various conditions (such as distance and band switching).

Step 2: Software Logs

Repair centres check system logs for hidden software issues, network switching errors, or modem crashes.

Step 3: Hardware Diagnosis

Technicians open the phone to check:

1. Antenna cables for damage or loose contact
2. Water or heat damage to signal chips
3. Dust, corrosion, or impact marks on the board

Step 4: Part Replacement

Depending on the issue, the shop may replace:

1. 5G antenna flex cable
2. Signal amplifier IC
3. Entire back housing (if antenna is embedded)

These components are small and sensitive, so it’s not recommended to attempt this at home.

Preventive Tips for Galaxy S25 Users

1. Avoid using thick or magnetic cases, as they block signal strength
2. Avoid charging your phone while using 5G for extended periods.
3. Restart the device weekly to clear temporary network bugs.
4. Use original chargers to avoid overheating.g

If you’re still facing connectivity issues, a full diagnostic check is the most efficient way to know what’s wrong and what needs repair.
