In Need Of Help. Not Sure Exactly What The Prob Is

Right basically.

My internet messed up a while ago. So one of my mums friends came and fixed it. And im preety convinced hes done something...

I cant get on the following

1. DA Chat
2. ANY online game where you battle etc against other people..

Basically anything that has direct contact with other people...
Wondering if anyone knows what the prob is and how I can solve it? =D

 

Could it be a firewall or something?

 

Firewalls turned of.
Nub.

if youre connected through the router, the routers firewall may be on, or some of the ports may be blocked.

 

My computer isnt connected to the router. Im on wireless Lan and the router is downstairs. Plus when it stopped working the router hadnt been touched. But ill look into that thanks.

 

any virus protection on? cause i found out i couldn't do the same cause the settings were blocking communication

 

Nope.
Took it all off and still got the prob.

 

FYI- If you are on wireless, it still goes through the router, that's where the signal goes to...

knowing that, it still could be a port not opened on your router..

 

ya you should forward your ports i suggest Port Forward

 

yep, that's the easiest way. they normally tell you what ports you must open at the website of the game/application

 

yea, I had this same problem when i reformatted my computer a month ago, it wouldn't let me play any games Online.

I got it fixed and they said, i needed to open some of my Ports =S

 

reformatting should have nothing to do with ports being blocked. It's on your router, not in windows...
