I have some weird issue with my wireless connections. I can connect to a network, it works for a few seconds, and then there's a DNS error, I can't browse or anything, on chrome it says DNS Probe finished, no internet. But I still appear to be connected. If i reconnect to the same network, it works again for a few seconds and then go down again.. And some other time, I can't even connect to any network as it keeps asking for authentication.
bcmwl-kernel-source is installed. I'm not used to linux so if you need any other piece of information, please ask.
It used to work fine as far as I remember, even thought i'm mostly connected to the internet with my cellphone by tethering.
I've try to look for answers on the internet, but to be honest I don't understand most of the proposed answers. My lubuntu is not brand new, and I don't remember exactly what I've installed.
If someone has an idea to help me, Thank you.
