strange school network problem

i just installed windows 7 rtm on my computer, but it won't connect to the internet.

i connect to the school network with a cable. i had the rc before and it worked just fine, but now it doesn't work. i have a laptop with the rtm and that works just fine.

whats strange is that, the computer tries to use a 192.168.0.* address while on my laptop where it works, it uses a 158.38.88.* address, i tried setting my computer up with a static address but my school network doesn't seem to support that.

besides it also seems to use different dhcp adresses

one has has the 192..... address
while the other has the 158.... address

does anyone have any idea what the problem is and how to fix it?

as a temporary solution i have connected the cable to my laptop and made an ad-hoc network

its impossible for a network, not to support a static connection.

Your computer is failing to register an address with the schools DHCP service

 

[krissgjeng]

well i didn't get it to work.

is there someway to force it to register an address with the schools DHCP service?

 

[Squall-Leonhart]

They are probably blocking your mac address.

 

[krissgjeng]

wouldn't the mac address be the same no matter what os i use?

the rc worked fine, and internet still works on windows xp on the same pc.

hmm i'll look more into it.

 

[Squall-Leonhart]

Not necessarily, i've known drivers to fubar up a mac address......

Install the latest Vista x64 drivers for the device.?

If it was failing to obtain an address via DHCP, it should be getting an APIPA address (169.254.x.x).

What happens when you clone your laptop's MAC address onto the desktop (after removing the laptop from the network)? You could try running Wireshark on both PCs during the DHCP process and see what turns up.

How is your school connection delivered to you and did you add any of your own network devices?

 

[krissgjeng]

it seems there was something wrong with the school network, in the end none of my pcs could get an internet connection and i couldn't get net access until now.

How is your school connection delivered to you and did you add any of your own network devices?

the connection is delivered with a normal cable outlet, with a lan cable from the outlet to my computer,
i'm only connecting my computer directly, no other network devices.

edit:
spoke too soon, it seems to work randomly, and now just on xp.

heres the ipconfigs for when it works
on win xp
Connection-specific DNS Suffix . : stud-bolig.himolde.no

and when it's not

192.168.0.1

this time i'll just try to not restart the pc or the connection.

 

[Squall-Leonhart]

windows 7 is not running on the same subnet for some reason,
im actually sure thats a Driver issue. download and install the latest vista drivers with xp, and then install them in windows 7

 

[krissgjeng]

it seems like there is some sort of conflict on the network or something.

it also happens in xp, and i have to repair the connection a couple of times before it works.

whatever it is i hope it get fixed, because this is getting irritating.

 

[Spyhop]

you know what this sounds like? Sounds like someone in your dorm (assuming dorm here) plugged in a router and your computer is randomly getting an IP from either douche's router or the school network.

 

[krissgjeng]

yeah sounds like it.

is there some way to force my computer to get the ip from the schools network?

Veldig mange av våre beboere har rapportert at de er utestengt fra internett
i løpet av helga. Vi har ikke stengt av og heller ikke it-senteret. I samråd
med it-senteret har vi funnet ut følgende: Problemene skyldes sannsynligvis
at en eller flere beboere har koblet trådløs ruter til nettet. Noen av de
trådløse ruterne er koblet feil. Nettverkskabelen fra datapunktet i veggen
skal settes i WAN porten, ikke LAN porten. Dere som har koblet opp rutere.
Vennligst kontroller at dere har gjort dette korrekt.

just got an email from the ones that manage the net, they say that many people have had issues connecting to the net, and that it probably is someone who has connected a router wrong and put the cable from the wall outlet to the LAN port in the router instead of connecting it to the WAN port thus causing these problems.
