Glad it worked out.
I apologize for glomming onto your thread but I want to vent a bit and/or ask for help.
My son and I built a computer for him, which he wanted to dual-boot in Windows and Ubuntu. It is a relatively new-ish Gigabyte mobo with decent but not earth-shattering specs, everything else good solid stuff, new or only lightly-used, which would have been excellent gear 2-3 years ago but is mostly 2nd-tier now.
Everything booted up and worked perfectly with a new install of Windows 8.1, but Ubuntu 14.04 stubbornly refuses to allow me to get online.
I have the built-in on-board Realtek ethernet socket, a Tenda 322 wireless USB dongle, and a Linksys ethernet card to choose from. Windows sees them all and accepts them all happily.
Ubuntu shows the Linksys with the ethernet cable plugged in with the little double-arrow icon in the corner, but will not actually allow anything to connect, ie Google or sudo update. The others are recognized as "something" in the connection drop-down menu but will not actually hook up to anything.
I have been to the Ubuntu forums numerous times, but nobody seems to know how to fix it. Naturally, they want to see the outputs of lists and configs, but then none of them seem to have any actual answers. It is always "well, it SHOULD just work .... "
I have the discs that came with the hardware, but there does not seem to be Linux equivalents of "drivers" .....
I am a Noob here, any suggestions?
