Ubuntu 16.04 wifi keeps disconnecting

[fix ubuntu] wifi connected but no internet access

I’m running Ubuntu 16.04 and have had a reported issue where the wifi suddenly stops working, despite the icon displaying connectivity but no link. This wasn’t a concern before, but it started happening more often without warning.

Problem wifi resolved on ubuntu 18.04

I found that my laptop’s wifi’sleeps’ when the screen is closed, making it difficult to leave it doing things that require an internet connection. For eg, if a backup upload is in progress, I’d lock the laptop and leave it to finish the job.
Turns off the device’s power management until it’s rebooted, but it doesn’t appear to have any effect on the wireless-sleep-during-screen-lock function. I tried something similar with a script in /etc/pm/config.d/wireless that did the same thing as above, but it didn’t work.
After learning more on how to disable suspend options, I had to use the dconf editor – I’m assuming this is only appropriate for the laptop (Surface Pro 4 i7) due to driver support problems, as my desktop does not have this problem. This happens even with ethernet connected via docking port, so it’s not a WiFi problem; it’s an Ubuntu suspend issue.
The alternative is to completely disable suspend and hibernate, which might seem drastic, but I don’t have any situations where I need the laptop to hibernate under Linux. I have to dual boot with Windows 10 (can’t help myself) and that takes care of the suspend functionality nicely.

Ubuntu wired ethernet connection keeps dropping out

In my experience, the interface can be stable for a long time, but it will occasionally disconnect and fail to reconnect/authenticate for a long time before becoming stable again. It rarely records the message “no beacon heard” and often disconnects for cause 4, which is inactivity.
In addition, I have instances of what appears to be the same error (cycling disconnect with iwlwifi time event over already error) in 5.1.15-arch1, which predates the implementation of that patch, and another isolated case in 5.1.4-arch1 (a separate AP as well), which predates the authorship of that patch. If you like, I will give you more logs.
For better or worse, I’ve been much less prone to making this mistake. Even though I use this laptop every day, the most recent example of the iwlwifi error for me was a spurious disconnect 1 week ago in 5.2.7-arch1.
I’m attempting to develop some sort of baseline behavior in order to determine whether or not the patch was effective. The bug hasn’t shown up in a few days. I’m curious if there’s any kind of stress I can add that will cause it to happen.

Solve internet connection problem on ubuntu 17.04

My laptop’s wireless network has always been unreliable.

Ubuntu: linksys wusb 6300 wireless adapter keeps

There’s a 10% risk that the wireless network won’t connect when I open the laptop lid and the machine wakes up from sleep. In the past, the only thing that has succeeded in this case has been a complete laptop reset.
None of them were successful.
It always needed a reset, but thankfully, I was able to find a solution.
You must dynamically disable the wireless network’s kernel module (driver) before re-enabling it.
My wireless network links immediately after this operation.
