I have a DELL Latitude D630 and Ubuntu 14.04. The WIFI work perfectly with all wifi networks a part from my office wifi network. It used to work in my office until last June but now it is not working anymore. I am wondering is it due to the fact that I have upgraded to Ubuntu 14.04 this summer and I have to re-configure something. Before upgrading I never had to configure wifi networks differently though. They all worked perfectly. Can you please advise?
I asked my IT department and they confirmed no changes were made to our office wifi network. I saw in other similar questions that the wireless driver may not be configured correctly so the adapter for my office wifi network may not be properly set up. If this is the case can you please advise how to configure the driver correctly? Please also let me know if I have to request from my IT guys the details of the wifi network and what details in particular.
