Depends on where your room is, but even the temporary barracks had some kind of (SLOW but still expensive) wifi..
You should be able to take courses there- to make sure you pass the first time you can take sec+ and ccna on skillport...
BTW all the power is 220v, dont' take 110v only stuff. (like fans or videogames or TVs) Check it all to make sure it will work.
I think I remember you can ship like 500lbs PLUS your army gear, might not hurt to take a bike or something else to do while not working. There are PT tracks and gyms and MWR stuff.
It is HOT and HUMID there. I watched the thermometer max out at 108deg while waiting for the chowhall to open for breakfast. The day got hotter although the thermometer couldn't show it..
(Also, do you know that you will be in Arifjan the whole time? I got PCSd there but then spent a month up the road at a different camp, then summer in Iraq then winter in Afghan. All in the 160th Signal BDE)...
Have fun with it!
Be Proud of what you do- and do it Well! ~me
