Redmi K20 Pro WiFi Problems and Fixes [Not Connecting, Disconnecting, Slow]

Toggle WiFi

If the phone isn’t detecting the WiFi network or it isn’t connecting to it, toggle the WiFi switch simply by dragging down the notification panel and check if it makes any difference. I would suggest toggling the switch several times so that whatever problem the system encountered when you tried to connect to a WiFi network is fixed.

Toggle the Airplane Mode

In case toggling WiFi doesn’t work out, try toggling the Airplane mode and that must do the job. Simply drag the notification panel, tap on airplane mode icon to activate it. Tap on it again to deactivate it. Repeat several times in order to boost the phone to start working with WiFi right away or you could move to the next method listed here.

Clear cache memory from your device

Cache memory builds up every day on your phone as you go on accessing apps, playing games, watching videos, listening to your songs, or working on an app, etc. The cache memory actually helps the phone by speeding up the retrieval process and reduces the overheads, however, cache memory is susceptible to getting corrupted easily. In fact, these cache memory accumulates too much that it will reduce the performance of the system considerably. It could cause any functionality such as WiFi as we are talking about it right here. Therefore, it is recommended to get rid of cache memory almost every day or two and here’s how you can do it.
App Cache: To clear app cache, go to Settings → Apps → Downloaded → Tap on an app individually → Tap on ‘Clear Cache’ & ‘Clear Data’ → Repeat the procedure for other apps.

Storage Cache: Open the Settings app on your phone and go to Storage >> Cache Memory. Tap on it to receive a prompt to delete it.

Cache Partition: This method requires users to log in to the recovery mode as you could follow in the ‘Reset the phone’ method listed below. You need to tap on ‘wipe cache partition’ to conclude the method.

Obstructions & distance do matter

These are two of the most prevalent reasons why you could be encountering WiFi problems on your phone. Either the phone is away from the router or modem that the signal is too weak or the internet is slow or the distance could be little but there are obstructions. Note that doors, walls, and even someone standing next to the router can seriously issue with the signal that your phone intercepts which are why reducing the obstructions are highly recommended. For this, you need to position the router higher from the ground and in such a way that it broadcasts signals to everywhere you want it to work well.

Reset the phone

Note that this isn’t much of an ultimate step as you would lose all your data in this process if you haven’t obtained a backup beforehand. Resetting the device is also known as the mother of all fixes which means the Redmi K20 Pro WiFi problems that we are discussing here will probably go subjected to the fact that it must be a software issue if the user does a factory reset. Here’s how you can do it about.
Step 01: Turn off the phone.
Step 02: Press Power + Volume Up buttons together and hold it until step 03.
Step 03: When Mi logo pops up on the screen, let go the Power button only.
Step 04: You can release the volume up button when the recovery mode screen pops up.
Step 05: Select ‘Wipe Data >> Wipe All Data’ using the power button to confirm, volume buttons to navigate.
Step 06: Confirm the following and the phone must reset itself.

Redmi K20 Pro WiFi Problems and Fixes

Problem #1: No connection to the WiFi

Consider that you are trying to connect the phone to the WiFi, however, you see that the phone is unable to detect your WiFi network. On the other hand, it is possible that you are unable to connect to a WiFi network even after trying several times. What do you do?

Fixes

#1: You can try rebooting the device. Doing so must help detect the WiFi network and connect to it right away.

#2: If the first method doesn’t work, try deleting the WiFi network in question and wait for a minute. Next, tap on the network, insert the password and try connecting to it again.

#3: If rebooting the device didn’t work in your favor, try rebooting the router for a change. In fact, doing so is recommended since the router could have overworked thus leading to problems like slow internet speeds or inability to connect to a network, etc. Turn off the router and wait for 30 seconds before restarting it and check out if it worked or not.

Problem #2: No Internet connection after connecting to the WiFi

This problem is common wherein you connected to a WiFI network but unable to access the internet. Well, if you are using a laptop or desktop, you can detect if the internet is working or not simply by checking out the ‘Limited’ status under the WiFi network. When it comes to smartphones like Xiaomi Redmi K20 Pro, an exclamation mark on the WiFi icon on the status bar must give the hint about it.

Fixes

#1: The first thing you should do in such cases is to check for intermediate issues. Hit up the ISP and get the diagnosis done to reveal if the problem in on their ends or yours.

#2: Routers tend to stay active for hours and even days without relaxing a bit. This can cause the system to suffer from overwork or overload which is where it tends to disconnects the internet temporarily. The fix to the problem is to simply turn off the router, tap on the reset button and wait for a minute or two before restarting it. This must resolve the issue at this moment.

Problem #3: WiFi connection keeps dropping off

Now, this is also a common issue where the phone is connected to the WiFi network, however, it drops connection abruptly. Swinging the phone a bit grabs the connection again and it keeps on wobbling and this could drive you crazy if you are in the middle of watching a movie or doing something that requires constant internet access. Well, here’s what you are gonna do.

Fixes

#1: Check if there’s any other device such as home appliances with microwaves causing the interference. If so, turn them off and check if the WiFi drops or not.

#2: It is quite possible that the neighbor’s router signals are causing your router to wobble a bit. If that is so, try upgrading the firmware of your router. Reset the router and start afresh. You can also tweak the channel i.e. from 2.4GHz to 5GHz if your router supports it where the latter is more spacious and you won’t ever end up getting entangled in constant signal drops from your router ever again.

Problem #4: The WiFi signal is weak

Another common issue with WiFi on Redmi K20 Pro is that the WiFi signal is weak. It could occur due to a number of reasons and here’s what you can do to fix it up.

Fixes

#1: Consider this. Your router is placed in such a way that there are too many walls between the router and the place where you are using the phone or computer. Walls can interfere with the signal and so are other any obstacles which are why you need to get rid of these interfering articles away by adjusting the router accordingly.

#2: If adjusting the position of the router isn’t an option, try lifting the router to a comparatively higher location i.e. if it was 2-feet above the floor, try lifting it up to 4-feet or more. This will magnify its signals as well. Furthermore, try alternating the antennas if you have two or more antennas on the router. This will ensure that the router broadcasts signals to a wider range than usual and thus, it must resolve the weak WiFi issue.

#3: You can buy WiFi range extenders which are external devices that you can affix at a certain location from the router where it will broadcast signals to a wider area without losing the signal strength.

Problem #5: Slow Internet speeds

If you are facing slow internet speeds on your Redmi K20 Pro, here are a few common fixes that you can try.

Fixes

#1: Adjust the antennas or relocate the router to get higher signal strength.
#2: Check the internet speeds on to know if you are getting the speed that you paid for or call ISP for the diagnosis and redressal of the issue.
#3: Download third-party app like ‘WiFi Analyzer’ app to detect the strength of signal across the house and use the phone in the sweet spots accordingly.
#4: Upgrade to a powerful router and that must fix the problem away.
