Cannot Access Internet, but Wireless card connected, can see IP address

I am using a Windows XP Home laptop, with a built-in wireless card Broadcom 802.11b/g WLAN.  I'm trying connect to the internet using my university's wireless networks, which require a client to manage the network connections, called AEGIS Client.  The problem is that everything seems to work fine, as the client is authenticated properly, I am reading a strong "excellent" signal, and I am getting the proper IP address when doing ipconfig /all, but I cannot access anything on the internet.  While another colleague can using the same processes, and I was also able to just a couple days ago.

I renewed IP many times, also restarted the computer many times.  I used the winsocksxp fix software also, and checked all the network settings to ensure that nothing has changed, and everything seems to be normal, DHCP, automatic config, etc. I also restored the system using XP restoration tool, to a checkpoint when I know it has worked properly (less than 2 days ago)

The only change that I have made to the laptop since the last time everything worked is that I brought it home and connected to my home's new Roadrunner modem.  The last time I checked, I was able to connect to roadrunner using LAN ethernet connection directly to the modem, however I did pop in the installation CD to check my connection as it seemed to be temporarily causing problems, but I was able to end up getting the internet at home.  When I brought it back to school this morning, I can no longer get into the internet using wireless.  I haven't gone home yet so don't know if it still works with Roadrunner  

I have also tried disabling the LAN while using wireless.  I'm beginning to think the installation CD did something evil, but I could not see any visible changes anywhere, I only used it to test my connection and made sure the connection was fine... I am running out of options, help!!

PS: SP2 installed 3 weeks ago, didn't seem to be affecting anything...

PPS: I'm recently getting this error that occurs randomly: Framework Service has encountered a problem and need to close . .. frameworkservice.exe application error ,etc wanna debug?? this seems to start only yesterday or today, seems to be in conjunction with my problem.

Also, I would try to find a different WiFi network to try and connect to. If you can connect and pull traffic on the other WiFi then I would go back to the IT dept and explain to them that you are able to pull traffic on other WiFi LANs etc. Hell show them this post... at least then they know that you attempted to solve your own problem and are not just being lazy and asking them to fix it.
If you cannot pull traffic on a different WiFi then there is defiantly a problem with your WiFi NIC either hardware or software (driver). What is the make and model of your laptop?
Have you uninstalled the Roadrunner software yet? Or restored to a point before you installed it? Just want to be clear before we get to deep.
Hmm could it be Network Address Translation?

Go to the IT center ( or whatever ) and as what range of IP addresses are supplied by DHCP. Specifically ask for one that is available at the moment (i.e no one is using it). Put this in your network settings and try to access it this way.  Set up the servers ip address as your gateway etc... This will determine that it is your laptops that is the problem if it does not work (which sounds like it is anyway).

Does your ISP provide a static or dynamic IP address?

Have you tried swapping the wireless cards with your friend?

Does the university monitor MAC addresses?

The installation CD should not affect a wireless connection, if it did then it is a blatant hack of a cd and you should probably discard it.
Thats about all I can offer you on the info you have given.

Good Luck

Thanks for the quick responses.  I don't know how to uninstall road runner software because Roadrunner software seems to be nothing but do configuration for the networks settings and test the connections, so I cannot see any programs actually installed in the "Add/Remove Programs section" or anywhere else.  It is a legitimate CD because I received it directly from a technician setting up my Roadrunner.  Time Warner Roadrunner provides one dynamic IP address.  I did restore to a point before popping in the CD.  

werdafucami, yes the university does monitor MAC addresses, and I did register with them and they didn't find any problems wit hthose.  
Very strange, I would head to the IT dept first. They may have changed something on ya, adn since you cant get your email how are you to know? Either way check there first, other than that maybe remove and re-install your wifi NIC.
Could it be the premables, try swithing from short to long or vice versa. Can do it using your wifi software.
Have you tried to ping to any sites?  by DNS and IP?

I advise to ping yahoo: ( DNS) and (IP)
See if either of those will work.

If they fail, try to ping another address in your schools network, like one of your collegues IP address.  This will see if it a problem getting from the schools network on to the internet.

While you are doing that also see if one of your collegues can ping to your IP.

Make sure any/all firewalls you have are off while you do this test.
Can you post the output of an ipconfig /all ?

intreeg, Below is my ipconfig /all

Retfirg, I also tried to ping sites, including and using it's IP, as well as another machine on the wireless network.  None of them worked (request timed out), one of the Network admin at school told me they do not allow pings to travel from the wireless network to any other network segments, but told me to try to ping to his laptop which is at, I guess same server as mine since mine is, and that didn't work...

I would also assume this means you cannot ping your gateway, DHCP, or DNS servers. I would try remove and reinstalling the NIC. Might not work, but is a quick process and eleminates that as a possible fix if it doesnt work. You are obviously associating with the LAN and pulling data in order to renew your DHCP lease.... might be a corruption in the TCP/IP stack. I used to deal with this a lot on 9x and DUN. Would have to remove and reinstall TCP/IP that was bound to their Dial-Up Adapter. Worked like a charm on 9x, just wondering if XP will have a similar bug.
werdafucamiConnect With a Mentor Commented:
Yeah I am stumped as to what it could be. As with the others all I can suggest is reinstalling the NIC, configure the Lan manually for Roadrunner and trying your mates wireless card. I am convinced that the university is doing everything correctly because your ipconfig looks perfect, it must be the fact that your internet connection has been screwed by the Roadrunner CD... And this isn't helping, I am just repeating what everyone else has already said!

Best of Luck

ok, I uninstalled the NIC by going to the systems tab and using that device manager, and when restarted laptop, the nic automatically installed.  (can't take it out physically as it's built in)  Still doesn't work.  I will try to connect it to my Roadrunner service using wireless tomorrow when the router comes in and see if that works.

My laptop is compaq presario 2596, celeron 2.6 ghz, 512 MB , comes with the built in wireless
Ok, well at this point I guess we will just have to see if you can connect with the roadrunner. Do you have access to another wifi nic or a public hotspot (like a cafe etc.)?

Ok, very weird, but after days of unistalling and messing around blindly with different things, this morning when I came to school it suddenly worked... still don't know what went wrong exactly but have split the points for you guys since you were helpful.  it also works at home with the wireless router as well...
Well now, I guess we have again proven that a PC is not a mindless tool and much like a nice automobile, can be very tempormental! ;^)

Seriously, I am glad to here you are back online... guess we will chalk it up to cycles of the moon. Please post back if you experince any more weird occurances... this one is going to bother me.

Thank you for the points! I wish I could have come up with a solid solution,,, errr,,,, explonation.
