Wireless internet problems

[Synthesis]

For some strange reason, I cannot connect to any linksys networks. It will say I'm connected, but will produce no internet (as in, I'll be connected, but cannot use anything that involves the internet. AIM will not work and no pages will load on my internet explorers.) please help!

Those open Linksys routers may allow outside MAC addresses to connect, but have no network privileges. I don't think there's anything you can do to fix this problem.

My sister can connect to it using her Dell computer, but I cannot. Solutions?

With my wireless I connect to it and it says im connected but I am not if I disconnect and then reconnect and then wait for like a minute i become connected.

There are always a few thing you can do,
-Restart The Computer
-Reset the Router

Those are a few things I guess, I wasn't sure if you said you were using a mac, but if not
-Disabble then Re-enable the connection

First of all disable not disabble
second of all if you are using a mac
IM SORRRY!
and i dont thing MRAC works for mac.
if it does whoever hacked/configured/produced it to work on a mac fails.
