LG-G5-not-connecting-wifi

Internet connectivity is one of the most important things in a smartphone but what if a premium and expensive phone like the LG G5 cannot connect to a Wi-Fi network?

We have seen a lot of problems and among them are connectivity issues like not being able to connect to Wi-Fi or can’t get good connection even if connected to a network. So, in this post, I will tackle three of the most commonly reported Wi-Fi related issues that LG G5 owners encountered and you’ll learn…

Read on to understand the problems I cited here and to learn how to fix them. If you have other issues with your phone, then you can always contact us by completing our Android issues questionnaire. Please provide us all necessary details about the problem so that we can provide you with more accurate troubleshooting guides and/or solutions.

How to troubleshoot LG G5 that can’t connect to Wi-Fi

There are several reasons why your phone can no longer connect to a Wi-Fi network and I will cover common ones in this section. I will also cite one problem sent to us that best describes how the problem occurs.

Hi guys. I own a G5 and it’s just 3 months old. My problem is about Wi-Fi. Everyday after work I go to this coffee shop to spend an hour while trying to read messages from friends, doing stuff on Facebook and Twitter while enjoying a cup of coffee. I have unlimited data on my phone but the thing is, the signal drops to 3G when I’m around that area so I opt to use Wi-Fi as provided by the shop. Recently, my phone stops connecting to it saying it’s ‘Obtaining IP address’ and then just goes to ‘Saved’ instead of ‘Connected.’ I asked the waiter about it but he, too, didn’t know what to do. So, my question is why is this happening and how can I fix this?

There are also different situations that lead to the same problem–can’t connect to Wi-Fi. As to the problem cited above, the phone can detect the network, remembers it but can’t get a connection. So, here’s what I need you to do…

  1. Ask the administrator, coffee shop owner or the waiter if they recently changed the password for their Wi-Fi network. If so, then you must obtain the new password and use that to connect.
  2. Assuming the password didn’t change, “Forget” the network from your phone.
  3. Reboot your LG G5, let it scan for available networks and connect to the shop’s Wi-Fi.
  4. Now, enter the password that you know. If the issue still occurs, then it must be an issue with the network itself. There’s nothing you can do about it except report it and hopefully they’ll fix it soon.

We just can’t continue troubleshooting especially if we know that it’s a network issue simply because we don’t have access to the router.

How to fix LG G5 that keeps losing Wi-Fi connection

Connecting to a Wi-Fi network is an easy job to do for the G5 but some units have troubles staying connected. Some owners reported their units keep switching from Wi-Fi to mobile data and vice versa as if the phone loses one connection and tries to connect to the other. Read the actual message we received regarding this matter below…

Not sure if I’m the only one having this problem but my G5 keeps losing its connection to my Wi-Fi. Thinking it could be a network issue, I already tried rebooting my modem/router but it’s still doing it. What I notice is that when it loses connection to my network, it automatically connects to data and I don’t want that because aside from the battery drains quickly, my area doesn’t have good data connection. That’s the reason why I subscribed for a faster internet to have better Wi-Fi connection. Do you guys know how to fix it? Thanks.

This is actually the result of the manufacturer’s desire to make its device “smarter.” The phone ought to connect to another network in the absence of the other but it seems the device has become so sensitive that a minor difference to the signal strength and it switches network. I think the problem occurs when you go a bit further from the router, go inside a room or a bathroom, or go outside.

The thing is, range is matters when it comes to radio signals. So, when the signal drops and the phone detects it, it will connect to the other network. By the time it detects Wi-Fi signal is strong again, it reconnects to it. In the process, connectivity is lost. There are two things you can do about this:

First, you can turn off mobile data if you really don’t want to use it. This way, the phone will be locked on to your Wi-Fi network due to the absence of the other. So, even if the signal drops, it doesn’t have a choice but to stay connected to the network or it will lose connectivity.

Second, you can turn off Smart Network Switch, which is responsible in automatic network switching. By doing so, your phone will stay connected to Wi-Fi no matter the strength of the signal. Here’s how you do it:

  1. Swipe down from the top of the screen.
  2. Touch and hold the Wi-Fi icon.
  3. Tap the Menu icon, then choose Advanced Wi-Fi option.
  4. Touch the checkbox next to Switch to Mobile Data to turn it off.

How to fix greyed out Wi-Fi button on the LG G5

Now, this one’s a bit strange and uncommon but you may also encounter it. In fact, there were already some reports from owners that experienced having the Wi-Fi button on their phones “disabled” or grayed out.

I know you guys would say ‘turn on Wi-Fi’ when if I said that my LG G5’s Wi-Fi is turned off but the thing is, it’s not really that simple. My Wi-Fi has been turned off on its own and when I tried to turn it on, I just can’t because it was greyed out or ‘disabled?’ I don’t really know how to describe it that’s why I contacted you guys. So, do you know how to fix this? Thanks in advance.

More often, this problem is associated with the system cache and it may occur after an update regardless whether it’s a big update or a minor one. But before we actually go after the cache, let’s try to see if the Wi-Fi button is enabled in safe mode. You know there are apps that can also cause this so the first thing you have to do is boot your G5 in safe mode and try to turn on Wi-Fi from there:

  1. With the screen on, press and hold the Power key.
  2. In the options menu that displays, press and hold Power off.
  3. ‘Restart in Safe mode’ prompt will display.
  4. Tap OK to restart in Safe Mode.
  5. Device will display ‘Safe mode’ at the bottom of the screen.

Turn on Wi-Fi if the button is enabled in this state. Once you reboot your phone to normal mode, the button should also be enabled. However, if the problem still persists in safe mode, you have no other option but to clear the cache partition.

 

  1. Drag down the notification bar and tap the Settings icon at the top-right.
  2. Tap General and then Storage. (If using List view, scroll down to ‘DEVICE’ and tap Storage.
  3. Wait for menu options to finish calculating, which will take a few seconds.
  4. Tap Cached data, then touch YES.
  5. Wait for the cached data to be deleted; depending on size it will take several seconds to complete.
  6. When the wipe is complete, the storage screen refreshes and cached data will not be listed. This means your cached data has been successfully cleared.

If wiping the cache partition didn’t work, then the last thing you can do is perform the master reset. Of course, you need to backup all your data and files first as they’ll be deleted. Once you’re done, follow these steps:

  1. Press and hold the Volume Down and Power keys. (Follow the order of the key’s to be pressed to avoid the device from booting normally at this time.)
  2. When the LG logo displays, quickly let go of the Power key but hold it again while you continue holding the Volume Down key.
  3. When ‘Factory data reset’ appears, use the Volume Down button to highlight Yes.
  4. Press the Power key to confirm the reset.
  5. When prompted with ‘Erase all user data and restore default settings,’ use the Volume Down key to highlight Yes.
  6. Press the Power button to confirm your action.
