Restart the Router [ How To Fix WiFi Authentication Error On Redmi Note 11T 5G ]
After attempting to fix the WiFi authentication error by restarting your Redmi Note 11T 5G phone, you can try the same with the router itself. As this device literally keeps running 24/7, it may introduce temporary glitches causing issues connecting to the WiFi at all. This could be a temporary issue or you could be seeing a hardware failure.
To verify, power off the router and keep it idle for a few minutes. Restart it and check whether your Redmi Note 11T 5G is able to connect to it or not. If not, try connecting your phone to a different access point (thus ruling out if your phone is at fault). Try connecting the existing router to another phone (to eliminate the probability of the router being at fault). Proceed if you are still struggling with the WiFi issue.
Your Router could have reached max devices
Wireless modems are great for connectivity as you just have to be in range to access the internet without any hassle. However, some routers have a limit of maximum devices that can be connected to them. If the devices reach the max limit, you might not be able to connect your Redmi Note 11T 5G unless an existing device isn’t disconnected for the time being.
If there’s no limit, it could be a bandwidth that is limiting a new device from connecting to the router after ‘n number’ of devices have already connected to it. What you can do here is to remove some devices and verify if the problem is rectified or not. Proceed if you are still struggling with it.
Change IP Settings [ How To Fix WiFi Authentication Error On Redmi Note 11T 5G ]
There is an assortment of features on WiFi on your phone that you can tweak to get the better of the feature. Changing IP settings can do the trick. Here’s how you can do it.
- Firstly, go to Settings >> WiFi & Internet >> WiFi.
- Select the WiFi network in question and go to its advanced settings.
- Change the IP settings from DHCP to Static. Keep a screenshot of the IP address on the static mode to keep it handy in case required.
- Change it to Static using the right settings you took a screenshot earlier and save it.
Update the phone
Outdated Android OS or the custom UI your phone is using can cause a series of issues and WiFi authentication errors could be one of them. Perhaps, you can resolve it with a software update. Here’s how.
- Go to the Settings app on your Redmi Note 11T 5G.
- Navigate to “System >> Software Updates >> Check for updates” or “Software Updates >> Check for updates” among others.
- Check if you have any updates in the box, and download and install it.
- If not, which is true in the case of Android phones given its nature, you will either have to wait or proceed with other methods in this guide.
Update the Router
At the end of the day, the router runs on the firmware to keep it operational. The router’s manufacturer releases updates from time to time which are patched automatically. However, it is quite possible that you might not have patched up the update where you can download it from the website. Go to the router’s admin panel to upload the software update and that’s it.
Reset Network Settings
Another express method to fix a hoard of issues is to reset network settings on your Redmi Note 11T 5G as a whole. Although this resets all connections i.e. you will have to enter the password of your WiFi, it is worth a try.
- Go to Settings in your Redmi Note 11T 5G and proceed to Backup & Reset >> Network reset.
- Tap on “Reset Network Settings >> Reset Settings”.
- This should do the trick.
Call in the big gun

Even if that doesn’t do anything positive, it’s high time you report the issue to a service center. You can go for an authorized or third-party service center each with their pros and cons. If it is a hardware issue, it is best if the professional gets it replaced or repaired rather than you experimenting on the device because you could end up causing more damage.
This was a set of generic and advanced troubleshooting methods you can deploy in order to fix WiFi authentication errors on your Redmi Note 11T 5G phone. Hopefully, you should be able to fix the issue.
