My development computer can only connect to LAN but not Internet

Post by Worlder » 2016/06/20 06:47:49

I really want to find a nondestructive solution to my issue.

Basically, at work, my development machine/workstation for the last six or so months since it was first installed has been able to connect to the Internet with no issue.

However recently it has been unable to connect to the Internet or if I'm lucky takes some time for it to be able to connect. However, I am still able to use the LAN due to the fact that I can print files to the various network printers around the office.

I'm not sure what caused the issue in the first place. What I do know is that for some unknown period of time between the first installation and now one of my co-workers decided to install a PCI Wi-Fi network adapter in the machine (security reasons apparently). That Wi-Fi network card has since been removed, but the problems still persist.

Like I said I would like to be able to diagnose the issue and fix it without having to re-install the OS.

I'm afraid you are going to have to wait until Thursday to get a response from me.

I only work on Thursdays and I'm literally the only one at the company who knows how to use Linux.
