Realme Wifi Not Connecting — Causes & Fixes (2026)
Why Realme phones on Realme UI 4, 5 or 6 fail to connect to Wi-Fi, keep dropping it, or show 'saved' without connecting, and how to fix it.
Problem overview
Realme phones running Realme UI on top of ColorOS use a shared Wi-Fi/network stack across the C, Narzo, Number and GT series, and connectivity problems tend to fall into a handful of recognisable patterns: the toggle won't turn on, a known network shows 'Saved' but never actually connects, the connection drops every few minutes, or speeds are far slower than other devices on the same router. Because Realme devices span MediaTek, Unisoc and Qualcomm chipsets with different Wi-Fi radio firmware, some fixes are more effective on certain chipsets, but the software-side troubleshooting in ColorOS is largely the same across the range.
The most common cause is a stale or corrupted saved network profile. Every time a router's channel, security type or DHCP lease behaviour changes even slightly, a saved profile on the phone can get out of sync, causing the phone to show 'Connected, no internet' or simply fail silently while other devices connect fine. This is especially common after a router firmware update or an ISP-side change, and the fix is almost always to forget the network and reconnect with a fresh password entry rather than trying to repair the existing profile.
Realme UI's own power-saving and connectivity optimisation features are a second major cause. Settings like Wi-Fi standby optimisation and the aggressive background app battery restrictions in Settings > Battery > App battery saver, along with the Super Power Saving Mode, are known to drop or throttle Wi-Fi when the screen is off to conserve battery, which looks like random disconnects to the user even though the router and network are fine. Dual-band routers broadcasting both 2.4GHz and 5GHz under the same SSID can also confuse some Realme models' band-steering logic, causing the phone to stick to a weak band or bounce between bands repeatedly.
Router-side issues matter too: too many connected devices exhausting the DHCP pool, MAC address filtering left on from a previous device, or a router that has simply been running for weeks without a reboot and has a stuck connection table, will all prevent a new or returning device from joining even though the password is correct. Public and enterprise Wi-Fi networks that use captcaptive portals or WPA2-Enterprise authentication occasionally trip up ColorOS's network validation, showing the network as connected without internet access until the captive portal page is manually opened.
Finally, on devices with a few years of use, a worn Wi-Fi antenna connector or a software bug introduced in a specific ColorOS build can cause a hardware-adjacent problem that a factory reset won't fully resolve, in which case a visit to a Realme service centre for a Wi-Fi module check is the appropriate next step.
Possible causes
Stale or corrupted saved network profile
A saved Wi-Fi profile can fall out of sync after a router firmware update, password change or DHCP change, causing the phone to show 'Saved' or 'Connected, no internet' without actually getting online.
Aggressive battery optimisation throttling Wi-Fi
Realme UI's App battery saver and Super Power Saving Mode can deprioritise or pause Wi-Fi activity when the screen is off, which presents as random drops that have nothing to do with the router.
Band-steering confusion on dual-band routers
Routers broadcasting 2.4GHz and 5GHz under one SSID can cause some Realme models to stick to a weak band or repeatedly bounce between bands, leading to slow speeds or intermittent drops.
Router-side congestion or stuck connection table
A router that hasn't been rebooted in weeks, has an exhausted DHCP pool, or still has MAC filtering enabled from a previous device can refuse new connections even with the correct password.
Captive portal or WPA2-Enterprise authentication issues
Public, hotel or office networks requiring a login page or enterprise certificate can show as 'connected' in ColorOS's status bar without actually granting internet access until the portal is opened manually.
Outdated or buggy ColorOS/Realme UI build
A specific system update occasionally ships a regression in the Wi-Fi driver that causes random disconnects or failure to reconnect after sleep, usually fixed in the next patch.
Worn Wi-Fi antenna connector or module fault
On older or previously repaired devices, a loose antenna connector or degraded Wi-Fi module can cause consistently weak signal or inability to connect regardless of software fixes.
Quick checks
- Confirm other devices can connect to the same network and get internet access.
- Toggle Airplane mode on for 10 seconds and off again to reset the radio stack.
- Check Settings > Wi-Fi to see if the network shows 'Saved' without connecting, or 'Connected, no internet'.
- Move closer to the router to rule out a weak signal causing timeouts.
- Check if the issue affects only one specific network or all Wi-Fi networks.
- Look under Settings > Battery > App battery saver for aggressive restrictions on background data.
- Restart the router by unplugging it for 30 seconds.

Step-by-step solutions
1. Restart both the phone and the router
Power off the phone fully, unplug the router for 30 seconds, then power both back on. This clears temporary radio and DHCP state on both ends and resolves a large share of one-off connection failures.
2. Forget the network and reconnect from scratch
Go to Settings > Wi-Fi, tap the network, select Forget, then search for it again and re-enter the password carefully. This clears a corrupted saved profile that is the single most common cause of 'Saved' networks that won't connect.
3. Toggle Airplane mode and reset network settings if needed
Turn on Airplane mode for 10 seconds, then turn it off. If the issue persists, go to Settings > System or Additional Settings > Reset options > Reset Wi-Fi, mobile data & Bluetooth to clear all saved networks and radio configuration at once.
4. Check Battery optimisation exclusions
Go to Settings > Battery > App battery saver and ensure Super Power Saving Mode is off during troubleshooting, since it can deliberately restrict Wi-Fi activity to save power and mimic a connectivity fault.
5. Switch the router to separate 2.4GHz and 5GHz SSIDs
In the router's admin settings, split the combined band SSID into two separate network names temporarily, and manually connect the Realme phone to whichever band performs better. This avoids band-steering confusion that affects some chipsets.
6. Check for a Realme UI or ColorOS system update
Go to Settings > Software update and install any pending update. Wi-Fi driver regressions introduced in one update are frequently fixed in the next incremental patch from Realme.
7. Test with mobile hotspot and a different router
Connect the phone to a mobile hotspot or a neighbour's/different router to determine whether the fault is specific to your home network or follows the phone everywhere, which separates a router-side issue from a phone-side one.
8. Run the built-in network diagnostics (advanced)
Dial *#*#4636#*#* to open the Testing menu, then check Wi-Fi information for signal strength and link speed readings, which can reveal a weak or unstable radio connection even when the status bar shows full bars.
9. Visit a Realme service centre for a hardware check
If the phone fails to connect reliably across multiple networks after a factory reset, book a diagnostic at an authorised Realme service centre to test the Wi-Fi antenna and module, particularly if the device has been dropped or previously repaired.
When to seek repair
If the Wi-Fi signal remains weak or the phone fails to connect reliably across multiple different networks even after a network settings reset and a software update, and especially if the phone has been dropped or previously opened for a repair, have the Wi-Fi antenna and module checked at an authorised Realme service centre rather than continuing to reset software settings indefinitely.

Frequently asked questions
- Why does my Realme phone show a Wi-Fi network as 'Saved' but never connect?
- This almost always means the saved profile on the phone is out of sync with the router's current password, security type or channel settings. Forget the network under Settings > Wi-Fi and reconnect with a fresh password entry rather than trying to repair the existing saved profile.
- Does Super Power Saving Mode affect Wi-Fi on Realme phones?
- Yes, Super Power Saving Mode and aggressive App battery saver settings can throttle or pause background Wi-Fi activity to extend battery life, which can look like random disconnects. Turn these off while troubleshooting to rule them out.
- Why is my Realme phone's Wi-Fi much slower than other devices on the same network?
- This is often caused by the phone sticking to a weaker 2.4GHz band on a combined-SSID router, or by a channel conflict with neighbouring networks. Splitting the router into separate 2.4GHz and 5GHz networks and manually choosing the 5GHz one usually resolves it.
- Should I reset network settings or do a full factory reset to fix Wi-Fi?
- Try Reset Wi-Fi, mobile data & Bluetooth under Settings > Additional Settings > Reset options first, since it clears all saved networks and radio configuration without erasing personal data. A full factory reset is only worth trying if that targeted reset doesn't help.
- Can a system update break Wi-Fi on my Realme phone?
- Occasionally yes — a specific ColorOS or Realme UI update can introduce a Wi-Fi driver regression that causes drops or failure to reconnect after sleep, and Realme typically ships a fix in the following update. Checking Settings > Software update regularly is worthwhile if this happens.
- My Realme phone connects to hotel or office Wi-Fi but has no internet — why?
- Many public and enterprise networks require you to open a login page (captive portal) or use certificate-based authentication, and ColorOS sometimes shows 'connected' before that step is completed. Open a browser manually to trigger the login page, or check with IT for the correct enterprise network settings.
