My Ubuntu laptop's wifi keeps disconnecting. It does it what seems to be randomly but frequently after periods of inactivity, though it does it when using the internet etc as well. I have to keep selecting the wifi network (I have the wifi network dialog box open permanently for this purpose). When this happens there will be period where it won't stay connected - it's like a click fest, where I select my network, it ticks it then it disconnects & unticks - repeat & rinse for about 30 seconds until it stays connected !!!!!! Really get on my nerves. Ran the network wireless info tool as shown here

Here is the results when connected Connected Wifi Results

When disconnected the same tool gives the follow error (no internet obv so doesn't work) -

https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info
Resolving github.com (github.com)... failed: Temporary failure in name resolution.
wget: unable to resolve host address ‘github.com’

Any ideas ??? Presuming a driver issue.

We see that there are two wireless networks with the same name: SKY7D544. I am quite confident that most of the reason for the disconnects is that your wireless device is roaming between them, always searching for a better connection.

If these are routers over which you have administration priveleges, I suggest that you rename one or both; something like SKY7D544A and SKY7D544B. Then ask your wireless to connect to the strongest of the two and I'm confident it will stay and not disconnect.

If you are unable to rename them, I suggest you ask Network Manager to bind to the stronger of the two like this: Ubuntu connect drops. Worked for a while then started dropping again

I have been having the same problem with Ubuntu 16.04 with Broadcom card.

The only thing which worked for me was installing WICD, a bit irritating that Network Manager can't cope but there you are.

I just installed it from the software centre but alternatively you could use:

sudo apt-get install wicd

Hope it helps you.
