The situation when the smartphone Samsung Galaxy A50 Suddenly losing access to the home network or constantly seeing "Obtaining IP address" messages can be frustrating for any user. This usually happens at the most inopportune moment, when you need to urgently reply to a message or finish an important instant messaging call. The problem isn't always a hardware failure; a software glitch or a router settings conflict is often the culprit.
Owners of devices of the series Galaxy A You may encounter various malfunctions: your phone sees the network but won't connect, or the list of available access points is completely empty. Before taking your device to a service center, it's worth trying a number of software methods, which restore the device to working order in 90% of cases. We'll cover a series of steps, from simple reboots to a full network reset.
Don't panic if the screen goes blank or the connection drops after unlocking. This is a common symptom of the system's power-saving algorithms. Android, which aggressively "sleep" the communication module to save battery life. Properly setting priorities and checking security certificates often solves the problem faster than a complete firmware update.
Basic diagnostics and module reboot
The first step should always be a simple reboot of both devices: your smartphone and your router. Over time, the router accumulates a cache of errors, which prevents it from correctly assigning addresses to new clients. Unplug the router from the power outlet for 30 seconds, then plug it back in and wait for it to fully boot up. Then, repeat the power cycle for your router. Samsung A50.
If a simple reboot doesn't help, try switching the module's operating modes. Turn it on and off. airplane mode (Airplane mode) every 10 seconds. This action forcibly restarts all radio modules of the device, including Bluetooth and GPS, which often resets a frozen network scanning process.
Pay attention to the behavior of the Wi-Fi indicator at the top of the screen. If it blinks or disappears, there may be a problem with the antenna connection, but more often than not, it's a firmware glitch. Make sure that app-specific traffic restrictions aren't enabled on your phone, as they could block system services.
Deleting a network profile and forgotten devices
A common cause of connection failure is a saved but invalid network profile. If you've changed the router password or security configuration, the old encryption key stored in your phone's memory conflicts with the access point's new requirements. You'll need to completely delete the saved network from your device's memory.
To do this, go to Settings → Connections → Wi-FiFind your home network in the list, tap it, and select "Delete" or "Forget Network." Then re-enter the password, paying close attention to capitalization and keyboard layout.
⚠️ Note: Deleting a network will also erase any static IP settings that were previously manually configured. Make sure you remember the current router password, as automatic recovery is not possible.
If your phone stops connecting immediately after a system update, the problem may be with the Google Play Services or system services cache. Try clearing the cache in the Settings app through the app manager, which you can find in the list of all apps.
Setting up date, time, and DNS parameters
One of the most subtle reasons for connection failure is system time desynchronization. Security protocols WPA2 And WPA3 critically depend on the accuracy of the watch. If the date on your Samsung A50 If the certificate differs from the real one even by a few minutes, the router's authentication server will reject the connection, considering the certificate invalid.
Check your time settings by going to Settings → General Settings → Date and TimeMake sure the "Auto-detect" box is checked or manually set the current, accurate time. After adjusting the time, try connecting again.
Another effective method is changing your DNS server. Providers use their own DNS servers by default, which can be slow or block some requests. Switching to public servers from Google or Cloudflare often speeds up response times and resolves the "Obtaining an IP Address" issue.
To change your DNS, go to your Wi-Fi settings, click the gear icon next to your network, select "Advanced," and then go to IP settings. Change the mode from DHCP to "Static" and enter "DNS 1" in the DNS 1 field. 8.8.8.8.
Reset network settings on the Samsung A50
If the previous methods don't work, you'll need to reset your network settings. This will return all connection settings (Wi-Fi, Bluetooth, and mobile data) to factory defaults. It's important to understand that this will not delete your personal files, photos or contacts, but you will have to re-enter passwords for all Wi-Fi networks.
You can perform a reset through the settings menu. The path may vary slightly depending on the version of the shell. One UI, but it's usually located in the "General Settings" section. This procedure clears system routing tables that may have become corrupted.
☑️ Checklist before resetting the network
After the reset, the phone will reboot. This is normal system behavior. The first time you turn it on, the Wi-Fi module will restart, which often resolves deep software driver conflicts.
Checking the router and frequency range
Smartphone Samsung Galaxy A50 Supports dual-band operation: 2.4 GHz and 5 GHz. However, older routers or incorrect settings can cause conflicts, especially if the network names (SSIDs) are the same for both bands. The phone may attempt to connect to the crowded 2.4 GHz band, ignoring the faster 5 GHz band.
Try temporarily separating the network names in your router settings by adding "_5G" to one of them. This will allow you to force the desired frequency to be selected from the list of available connections on your phone. The 5 GHz band is less susceptible to interference from microwave ovens and neighboring routers.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 450 Mbps | Up to 1300 Mbps |
| Range of action | High (breaks through walls) | Average (poor at overcoming obstacles) |
| Interference level | High (many neighboring networks) | Low (cleaner ether) |
| Compatibility | Works with all devices | Only with modern gadgets |
It's also worth checking the encryption type on your router. For maximum compatibility and security, it's recommended to use WPA2-PSK (AES)Using legacy TKIP encryption or mixed mode may cause connection errors on newer versions of Android.
Safe Mode and Third-Party Applications
Sometimes third-party apps, especially antivirus programs, VPN clients, or memory cleaners, can block connections. To eliminate this, start your phone in Safe Mode. In this mode, only system apps load.
To enter safe mode on Samsung A50 Press and hold the power button on the screen until the "Safe Mode" icon appears. Tap it. If Wi-Fi works reliably in this mode, then one of your installed apps is the culprit.
⚠️ Note: Some phone features will be unavailable in Safe Mode. Don't be alarmed if the interface looks slightly different or game shortcuts disappear.
How to exit safe mode?
To exit Safe Mode on your Samsung A50, simply reboot the device as usual. Press and hold the Power button, select "Restart," and the phone will boot into normal mode with all your apps running.
Analyze recently installed apps. Remove suspicious programs, especially those that require network access or manage your connection. Free VPNs with intrusive ads are often the culprit.
Hardware problems and factory reset
If none of the software methods helped, it might be a hardware issue. The model Samsung A50 The antenna module is integrated into the bottom of the case. If the phone has been dropped or exposed to moisture, the antenna connector may become loose.
A radical but effective method is a full reset to factory settings (Hard Reset). This operation will completely delete all data from your phone's internal memory, including photos, contacts, and apps, so be sure to make a backup.
To reset, go to Settings → General settings → Reset → Factory data resetOnce the process is complete, the phone will be as good as new. If Wi-Fi still doesn't work, the probability of a hardware failure in the chip or antenna is over 90%.
In some cases, reflashing the device using Odin helps, but this requires certain skills and searching for official firmware specifically for your model and region. Improper flashing can render the device completely inoperable.
Frequently Asked Questions (FAQ)
Why doesn't the Samsung A50 detect 5 GHz Wi-Fi, even though the router is dual-band?
Your router's 5 GHz band may be set to a different region than yours, or the broadcast channel may be outside the supported range. Try manually setting channels 36-64 or 149-165 in your router settings.
My phone says "Authentication Error" even though my password is correct. What should I do?
This often indicates an encryption type conflict. Try temporarily disabling WPA3 on your router and leaving it set to WPA2. Also, check if MAC address filtering is enabled in your router's security settings.
Can a case affect Wi-Fi signal reception?
Yes, if the case has a metal coating or metal inserts. Metal shields the signal. Remove the case and check the reception. Thick rubber cases can also slightly weaken the signal, but rarely block it completely.
How do I reset my network settings if the menu won't open?
If the interface freezes, you can try entering the code in the dialer ##4636## (This doesn't work on all firmware versions) to access the test menu. If this doesn't help, the only option is to reset the phone via Recovery Mode (press and hold the Volume Up + Power buttons while the phone is off).
