Here at school (George Mason University) I am having some funky issues with their wifi.
They have 2 main networks you can connect to on campus, GMU and MasonResNet. When I connect to ether network, I have the same problem it connects to 4 networks at once and slows the heck out of the connection. I know that made 0 sense so let me give you an example, I'm currently connected to GMU3 GMU4 GMU5. If i try to disconnect from one, I disconnect form all of them. Is this problem on my end or theirs. I have a 2 week old Gateway NV5214u with vista.

First let me say, after looking at GMU's wireless coverage that is fairly sweet.

Below is something I haven't seen before lol. First is all the IPv6 addresses. Which aren't needed and I have looked around the GMU site and see no mention of them using IPv6. So I would disable it. This site up to step 4 will tell you how. Unless you start doing VPN there is no need to edit the registry. If you want you can do this on both the Wired(Local Area Connection) and Wireless. when you click OK after step 4, reboot the PC. If this causes you to not be able to connect at all then reverse the instructions.

The other part isn't a bad thing its just the IP address below, its a full on class A route-able address. :thumbsup:

IPv4 Address. . . . . . . . . . . : 42.180.250.175(Preferred)

You prolly know this but the ITU Support Center (Room 233 in Innovation Hall) is open M-F, 8:00 a.m. to 7:00 p.m. I have a feeling that when you remove the IPv6 its going to solve your issue but I might be wrong lol. If disabling IPv6 doesn't solve the issue and I had full on IT support avail to me, I'd stop over at that building and ask them what is going on. They know FAR more than me about the school's network. And its not that I think we can't figure it out but when you are in school you just want your network to work. You don't have time to post, wait for me to post, try what I suggest, post, wait for me to post....get the picture? You have beer to drink!! Oh and study hehe.

Hope this helps thumbup.gif

Hey thanks for the help. As for now, the problem seems to have fixed itself, but if it rares its ugly face again, I'll give your suggestion a try. They have Wifi pretty much ever were on campus and when its working right, its pretty damn fast. I was not happy that they forced me to download some form of Norton "I Dont stop bleep." Their network security does piss me off a bit too. Every time you join their network and then randomly throughout your web browsing, you have to log back in. All of which is not a huge deal but it does become a pain in the ass when you use your itouch as much as I do because loging in on that tiny keyboard suck (not to mention the make us use passwords that consist of 7 characters or more, Upper and/or Lower case letters, numbers, symbols, ect.)

One question though. You said that our network is on , "a full on class A route-able address." I've taken a few networking classes and wouldn't the subnet mask suggest its on a class B network? Or were you referring to the IPv6 which I know little to nothing about. haha.

I'm glad it fixed itself lol

The address is still a class A but you are correct that is a class B subnet mask. It doesn't change the fact that its still a class A address it just means they took 8 bits of the host to make more networks.
