At school, I noticed my laptop couldn't connect to the school's wireless network (kinda annoying, because I was working on a powerpoint with a few people after school and wanted to insert some images). It didn't matter if I did it from the other end of the school, thus a different access point, it still didn't work. I could connect, but windows still said "no internet access" and I couldn't load anything. This worked before. Their network is 802.11b/g/n and has no security (you type in your username and password in an internet browser landing page). At home, it worked fine (WPA2-AES security). I plugged in an old 802.11b/g router I had, set it up for bridging and connected it to my regular 802.11b/g/n home router, and called it the same thing as the school's network, with no security. Windows connected and it worked just fine, but it called it "[name of the school's network] 2". Huh? I went into regedit, searched for "[name of the school's network]", and deleted those keys (it looks like I ended up in the part of the registry that stores wireless networks, because familiar network names were there). I then logged out and in again, and hopefully this will work (I'm going to bring the computer to school again tomorrow just to be sure that I fixed it.). The computer has Windows 7 Home Premium 64-bit SP1.

Dang it... it still didn't work! I got the same thing - windows connected, but said there was no internet access, and I had a 169.254.*.* something IP address. Again, I disconnected, went into the registry and deleted the stuff about that network, rebooted, and got the same problem... it shows all the networks just fine and it works fine at home. I'm sure I tried a different access point as I tried this on different ends of the school.

Sorry for the delay, it is so busy on the east coast.

Is your computer being hibernated/in sleep mode at any point in time while at/going to school? IP-stack crashes are somewhat common when resuming from sleep.
Which wifi card do you have?
Is your school using private or public IP addresses? (TN Tech uses public, Win7 + some non-intel wifi cards hate it!)
Have you tried manually assigning an IP address?

Also, IT support? Chatted them up lately? There's gotta be an office somewhere...

I ended up asking the IT guys about it, and they had the same problem connecting to that subnet with a different laptop. I think they changed something, because now it works again.

Some computer has a switch to close the wifi signal. Did you have open it?

[LiveBrianD]

My PC doesn't have a wifi switch. However, it was enabled via software and detected nearby networks just fine. (It was just giving me 169.254.x.x IP problems at school.) At home, it automatically worked fine. I took it to school the next day, same problem. At home, worked fine. It clearly wasn't a problem with my computer, and it was later fixed.

i just know when you use the dynamic way to get ip and the connect was failed ,then the computer will return a IP like 169.254.*.*.
