What wireless USB network dongle will will work with a samsung C7000?

Answer 1

D-link dwa-140 should work fine.

Last time i checked, they were around $20-$25 on ebay, which is a lot cheaper that the Samsung rip-off dongle (which in essence, is nothing but a re-badged DWA-140!).

Make sure you check the version of the D-link DWA-140 before you buy. I bought the B2 ver 1.71 and can't get it to work on my Samsung tv.

Answer 2

Any that do not need to install software to use. They're rare but they're out there.

Be aware tho they may use a "proprietary" Usb Adapter like the X-Box had and the 3rd party adapters may not work.
