Today I spent a long time struggling with what turned out to be very basic networking issue. I'm trying to move from Window's built-in VPN software to the mobile VPN software that watch guard puts out which in turn works with my XTM 505 Firebox. I'm still trying to make that move because I had to spend most of the day correcting issues with my air card which I will need next week as I travel.
For whatever reason, my laptop decided all of a sudden that it did not want to recognize the USB connector lightning AT&T provided me or the Dell wireless 5530 air card (C6807R). I tried several options to fix this issue all of which proved to be superfluous. My normal fix, simply uninstalling and reinstalling the device drivers, did not work.
What ended up working was going into the Device Manager -> Modems -> Right Click -> Properties -> Advanced Tab -> Advanced Port Settings and then looking at the very bottom of the window by the COM port number drop-down. I simply selected a different port dollars order using hit okay and like magic everything was fixed.
FYI I am using Windows 7 Professional 64-bit.
