I have Mac os X 10.4.8 and I have Windows XP through parallels build 1970. I previously had 1966 and with both builds I never had a problem connecting wirelessly. It just configured everything for me. Today I plugged in straight into my cable modem because I wanted to download some large files quicker and my internet doesn't work. It says I have limited or no connectivity(Windows). Internet works fine on the mac. Is there a setting I'm supposed to change to be able to use the internet this way?
