Okay, I am having some problems..So of course, before contacting Apple, the ISP, or etc....I am turning to my faithful members at MacRumors. I just got to college a little while ago and set up my Buffalo wireless router on one of two ethernet ports on the wall. My girlfriend's Dell is contacted wirelessly and is on the other side of the room and my PB is right next to the router, hardwired to it. The internet has been working find for me, whether plugged in or using Airport, until...Yesterday. I check my email yesterday morning, only to come back in the evening and to find out that my internet was connected via ethernet, but no web pages would work. I don't have any clue what could have happened. So then, I unplugged and connected fine to my wireless connection, aptly entitled "Jet." I was connected fine, went to Safari...nothing. No pages would load. I was stumped. I checked over things for hours. In my Network status it shows that I am connected (little green light) successfully and gives me my IP and everything...Yet, Safari, Mail, iChat...NOTHING. Same thing with Airport...It shows I am connected fine but still nothing works. My girlfriend's Dell connects fine to my wireless network and surfs easily. As well as I also connected to random people's wireless networks like "linksys," "Ruby," "Paul And Sarah," etc. ALL of them worked. I could surf on their wireless networks. Then I tried to connect directly to the ethernet ports on the wall...Same thing. It shows I am connected with an IP and all, but nothing. So now I have no idea. I suppose this means that it has to do with MY computer on MY specific ethernet ports on the wall. I really don't know what step to take next..The only thing I remembered installing maybe that day, or the previous night was an Apple update, an Apple Remote Desktop server update thing..Maybe that's it?..Anyway..I have tried everything.. Zapped the PRAM, FSCK, repaired permissions... So what am I supposed to do? Does anyone have ANY ideas?
