Why does my laptop keep disconnecting from my wifi?

My laptop is constantly disconnecting from the wifi. I mean like only a minute after reconnecting it to the wifi. I've determined that it isn't the router, since all of my other devices don't have a problem staying connected. Nevertheless, I have still tried restarting the router but it doesn't work. I've also simply tried restarting the laptop, but that also didn't work.

My laptop is a Dell and has Windows 10, with a 64-bit operator.

Is this a good question?

Hi,

What is the model number of your laptop?

Does it stay connected if you are using it close to the router, say within 1 metre?

Hi Kicki Squi,

I think you may have given me a serial number not a model number. There should be a label on the back of the laptop with the information on it.

Here is an example for a Dell Inspiron 1750

Does it manage to connect in the first place?

Sorry jayeff, I don't know too much about this stuff. How about Dell Inspiron 3558?

George A., yes it does.

Try forgetting the network then re-entering the password. Sometimes the device thinks it's connected then relizes it's not. I does that because the password is wrong.

Hi Kicki Squi,

Verify that you have the latest Dell Win 10 64-bit WiFi drivers installed in the laptop.

Here is a link to the support page.

Scroll down and click on the Network (9 Files) link to see the various options.

You will have to go to Device Manager in your laptop to find out exactly which make of WiFi you have installed, so that you can download the correct driver. To get to Device Manager, right click on the start button in the lower left corner on the Taskbar. An options box will appear on the left side of the screen. Click on the link to Device Manager.

When in Device Manager, scroll down and click on the + sign next to Network Adapters to expand the list and then find the make and model of the WiFi network adapter. When you have found this you can download the correct drivers from the Dell download page.

Once you have downloaded the driver, (remember where you saved the file to), go back to Device Manager and right click on the WiFi network adapter, select Update driver and when given the option to Search online or select from a disc etc, select that option and then point to the saved downloaded file location to begin the driver update.

If updating the drivers doesn't help, try downloading and installing a free WiFi scanner program to get information regarding things such as WiFi signal level and the network channel number to see if there may be either a hardware problem with the laptop or perhaps interference on the network affecting your laptop

I'm sorry, in the Device Manager under Network Adapters, I don't know what I'm looking for. There is an Intel Dual Band Wireless-AC, Realtek PCle Family Controller, and several WAN Miniports.

Hi,

As there is only 1 Intel driver WiFi driver file (not the Intel Wireless Display Utility) I suggest that this is the one you need.

Don't worry, if it is the wrong one Windows should advise of this when you go to install it and shouldn't install it.

by

Okay, thank you. I will try installing that.

by

Sorry, but the driver wasn't accepted. :( The wifi scanner isn't coming up with anything wrong either.

Hi,

Are there any red crosses or yellow exclamation marks next to the WiFi network adapter in Device Manager?

What signal level is being shown by the WiFi scanner program for your network? Are other networks being shown as well?

Remember that they are -ve values so the higher the number the lower the signal strength, e.g. -100dBm is weaker than -92dBm
