2 At once?

Is it possible to have 2 people playing 1 guild war account at once but different char's?

No as soon as the second person logs in the first person is logged out

My roommate used to do this to me for fun hehe

So in order for my to play online with my son, I need a second account?

Yep pretty much

That's what I did, got 2 accounts that I share with my son. It's nice to play side by side, adds a nice touch to the game.

which router are you using (wireless or standard) and have you had any problems with it?

What does that have to do with him playing GW with his son?

Because some router for internet connections if you have 2 people at the same time in the house playing certain games (e.g. Guild Wars) mess up with it or are incompatible, so Loviator's probably asking which works.

just a shot in the dark, but perhaps he's asking about technical aspects of the actual configuration of the two comps next to eachother, whether signals interfere, etc. Again, just a shot in the dark.

As far as playing side by side, at least 2 couples in my guild do this, probably 3, but i'd have to ask the third couple.

As far as myself, I play downstairs and my gf plays upstairs. She connects to me thru a wireless router.

My husband and I LAN together all the time. Our desks are side by side and we have no problems.

My BF and I play together over a wireless (in seperate rooms) and have no problems either
