Summary of what I want: Home network with internet connectivity for 2 computers Host laptop computer connected directly to Comcast and use wireless cards in both laptops to set up an ad-hoc network where use Internet Connection Sharing to share internet to second laptop. Basically so both computers can be on the internet until we buy a wireless router eventually, or in the future when I want host computer still hard-wired for faster connection. Situation I have: Summary: Can only see internt sites affiliated with university where sometimes client computer is used. Details: Host: XP PC connected by ethernet wire to Comcast cable internet and everything works on the host computer as far as internet still Client: connects to host via the wireless cards on ad-hoc network and it can only go to internet sites associated with a large university system where my wife (owner of client laptop) works and where the client computer will continue to be used occaisionally via ethernet cable to their network. It is not cached pages because my wife is able to check university e-mail from home on the client computer. And as this is a large university system, it still works from multiple campus sites in multiple cities far away. But things like google or yahoo time out. It happens in both IE and Firefox. I have looked for proxy settings in both browsers on the laptop and see nothing. I have tried with both client and host firewalls off and with host one only on. My wife said that it did take her dealing with University IT people to get her laptop to work at the university but she does not recall any of settings they had her tweak to get it work. Their building is not wireless yet so it has to be ethernet cable. Question: Clearly the as-hoc connection works and the something is able to get through because all the university internet sites work but where should I look to find something limiting it to universtiy sites? When I get back on the ad-hoc network at home I plan to verify the client can ping the university sites it accesses but I assume that is obvious it can. Clearly the problem has nothing to do with Comcast because I would imagine client would be limited to Comcast stuff if that was the case. And host computer works just fine all over internet. I also assume once I found the limiting factor I would be able to tell wife how to change settings back so she can use laptop at the university as well. It just seems like I am so close to having internet access on client computer if it works on University-affiliated sites at home?
