Wifi connection drops in Ubuntu 16.04

Asked by Sam Jackson

I have a Lenovo Ideapad 110, and I have wireless connectivity issues, but can't figure out whether it is a hardware or software problem. I have Ubuntu 16.04 installed alongside Windows 10, and on each OS, there will be times when my wifi connection will drop while I have a full signal. It happens frequently when I log in after the machine has been in sleep mode or the lid closed, but it's happening more and more during use.

The only way I have seen to re-connect is to turn the wifi off, then turn it back on so that it will automatically connect again. I don't show any breaks in my router's connection, and no other devices such as cell phones have this problem. Is there any way I can check to see if this is merely an issue of the Linux distribution? Again, I lose connection when I am running Windows at times, too, but it happens far more frequently now when running Ubuntu, although it is my preferred OS and I run it much more often.

Have you tried rebooting your router?

Yes. I have rebooted the router, changed routers and rebooted the modem. I no longer have connection problems with Windows, but every time I'm using Ubuntu, the wifi says it has a full signal, but stops connecting to web pages every 30 seconds.

What is the output of:

sudo lshw -C network; lsb_release -a; uname -a

Thanks

Nope. still kicks me off wifi every few minutes but still shows a signal. I still have to turn wifi off and then back on to reconnect.

Still kicks me off. I'm using strictly Windows at this point. I can't even get it to stay connected for more than a minute.

Is it possible that some of the packages I had problems with previously are causing my problem with wifi now?
