Ask Ubuntu Asked by s.ouchene on February 22, 2021
I spent more than 2 weeks searching for a solution to the following problem without success:
On my Ubuntu 18.04, I am connected to a Wifi (named “SmartCampus”) but the internet keeps dropping frequently (I don’t know exactly the intermittent time interval, but I think it is variable. For a rough estimate: between 5 min to 15).
However, I can confirm the following:
When I do that , the internet works again.
Could you please tell me what is the problem? What can I do to fix this, because that’s very annoying.
Here is the result of wireless-info script
: wireless-info-report
I appreciate your help
I think that this is not a problem of your Ubuntu, but of the network itself.
The idea of restarting the network services is a bad one, because everything it does is only managing the network services not the connection and the speed. Usually, in wireless network because there are a lot of other access points we can consider interference as an opportunity to lose a successful connection.
You can contact the administrator of that network to find out the root cause, but remember to check the connectivity between you and the router by simply pinging the gateway to check whether you are connected or not.

I've had same exact problem and its quite frustrating (a question mark appears in wifi icon during download and wifi stops working).
The only way I got connection to work consistently was to "turn off" wifi then "turn on" in wifi dropdown menu. Rebooting did not help.

I had faced same problem. You have not mentioned if you are using NetworkManager.service
. In my case not only wifi but Ethernet speed was also reducing frequently. The work around that worked for me I am sharing here.
I installed Wicd using sudo apt-get install -y wicd
.
After that the problem almost gone. When ever I face reduction in speed I run following:
sudo systemctl stop NetworkManager.service
sudo systemctl start NetworkManager.service
Hope this will help you.

As chili555 said the problem is that there are a great deal of instances of SmartCampus. Only one of them is of any real use to you so you should bind your connection to it using the instructions here Ubuntu connect drops. Worked for a while then started dropping again
