Free wifi network, "DIA". Choppy & unreliable, frustrating even for light browsing, so forget about Skype calls etc. International power outlets at the cubicles with big E sign, next to gold lounge.
Free WIFI + free lunch/dinner (flying with Qatar Airways), if you're staying longer than 5 hours. Ask at the information desk in front of gate 12 for the vouchers. Interesting people... ;)
