This is the SSL certificate installed by default on ZyXEL VMG1312 routers, I know because mine has the same certificate. It looks like your computer is attempting to communicate with your router using an encrypted protocol (like SSH or HTTPS) and is warning you that the certificate is invalid. The certificate expired in 2006 so there's no way to trust it. ...

You installed an unsupported kernel. The driver does not build. What is the point of installing it? you could install kernel 3.19 to 14.04, or upgrade to Ubuntu 15.04. You built mainline kernel form source. It was not a best idea for Ubuntu. Anyway you do not have to build kernels yourself. All mainline kernels are available at Ubuntu mainline kernel PPA. ...

If it is not, I suggest you check the wireless switch or key combination. You can see if the device is being turned off by the switch with: rfkill list all If ...

This was the same case for me, but the drivers that worked on the bootable USB are still on the USB. If you first open the bootable USB in a file explorer then search with ctrl+F for "dkms" and install that .deb file and then search for "bcmwl" and install that .deb then your card will work again.

I suggest installing Broadcom wl driver for this chip. Run in terminal sudo apt-get install bcmwl-kernel-source If you choose to keep b43, you can edit that file in /etc/modprobe.d/ in Ubuntu too. But wl should be more stable. But if everything works there is no need to worry
