Constant screen freeze/disconnect

I've been playing on Lordeaeron for 2 days, I my wow clients keep on freezing up every 30mins-1hour, it's fine when there's no queue to get on the server, I just reconnect no problem. But when there's a 300 queue to log on and I just get disconnected again after 10seconds it gets kinda annoying. I'm not complaining about the system or anything, if someone can help me to identify the problem I would be very grateful. I don't think it's my internet as I am on skype with my friends the whole time and there's no issue there. My laptop specs are pretty good as well, bought it a year ago for quite some dollars.

Any suggestions what could be the issue or how to fix it?

Thank you
