My wifi keeps dropping connection constantly. I really want to use Ubuntu as a main OS, but this wifi problem is an issue. In the past, upgrading the kernel fixed it, but it isn't fixing the problem this time, unfortunately.

Here's some things I tried:

sudo apt-get install linux-firmware-nonfree

Also tried purging bcmwl kernel source, turning off ipv6, upgrading the kernel, and disconnecting the wifi.

My CPU is a i3-3110m with HD4000.

FULL specs of my laptop:

Only mentioned Intel drivers above as I know integrated drivers are very common, so there could've been an easy solution knowing the graphic drivers.

    Your hardware specification link does not provide hardware information for your WiFi card. Please provide full hardware details as explained in this Q&A (section Identifying the exact hardware). [edit] your question to provide those details. CPU/GPU specs aren't relevant, we need numeric vendor/product IDs of your WiFi chip to help you. Without this, it's just all guessing. Please also include the exact Ubuntu kernel version you are running (uname -a). – gertvdijk May 07 '15 at 13:50
  • We need specific information about your Wifi chip. Please see http://askubuntu.com/questions/333424/how-can-i-check-the-information-of-currently-installed-wifi-drivers run the commands there and copy the output and edit your original question with the new information. – user68186 May 07 '15 at 13:54

    Flagged as unclear because requested hardware information is not provided by OP. – gertvdijk May 09 '15 at 16:58
  • have you checked your router settings that NOACK is not enabled? If NOACK is enabled, it can cause this type of behavior – mchid Jul 24 '15 at 03:55
  • Look at the network logs with the terminal command: sudo journalctl -b 0 -u NetworkManager. Read man journalctl NetworkManager service. Also do: service NetworkManager status and service --status-all. Do not reply via Add Comment. – waltinator Oct 20 '23 at 03:47
