I had been using Mirc for years on a Model Dial up connection. When I upgraded my connection to Charter High speed I received the 10053 error every time I tried to connect.

I played around with my ports and some settings and I can connect to a server and the default channel. People can see that I'm on but I cannot type to them or join channels. I'm disconnected 30 seconds to 1m later due to error 10053.

Also, MSN worked before the ISP changed and now when I connect to it my whole net crashes and I need to reset my router.

Help =(
