So I bought my brothers old XPS 400. Had 512mb ram, upgraded it to 4gb. The computer was running the newest version of Ubuntu and the wireless card worked great. I decided to put in Windows 7 32 bit, that didnt work, upgraded to 64bit Windows 7 and still wont work. I updated the Realtek drivers and no marbles.

Currently it tries to identify. But wont. Wont connect. I have done so much research and nothing has worked. Thinking i need to get a new wireless card. The card is a Realtek 8185 extensible.

Tried:
Winsoc - Got a bunch of random errors. Didnt work
Different network - still wont connect
Fresh Windows install
Manually installed drivers
Even tried doing some stuff with wireless registry keys that were recommended

Nothing will work. Am i out of luck? On my laptop i am just used to stuff just working... this 7 year old desktop is tricky and new ground for me. Ultimately i just want it for a media server to my TV... just dont want to run that dreaded blue cord across the living room.

i can think of a few reasons you'd have trouble. the most likely is you don't have drivers that work with your hardware. is the device working properly in the device manager? if it's alright the most likely explanation to me would be that your wireless router is using a transmission format that windows 7 doesn't use, or is incorrectly identifying.

since most routers can be hardwired to the pc, hardwire it, and log onto the firmware and check the wireless network settings. i'd be willing to be the problem is there.

The router is brand new. We have two other newer computers on Win 7 that are linked just fine.

yes... but does your wireless in your pc use the same networking protocols?

many older parts don't use modern networking protocols. I've fixed plenty of older wireless networking issues when someone in the house bought a new router and suddenly all the older windows pcs with their older networking cards couldn't connect.

simply changing the encryption format (to an older legacy format) in the routers firmware solved those problems.

That I am 100% unsure of. My laptop is a year old and the XPS is seven years old lol. Just baffles me that it worked on Vista, on newest version of Ubuntu and not on 7

Would that by chance be disabling DHCP?

i'm just tossing out ideas. it seems to me your router works, other systems are connecting. assuming you have the propper drivers installed for that wireless card your pc should connect too.

that said, it's also possible windows 7 is trying to connect to the wireless network, for reasons we don't know, with your hardware in the wrong encryption format.

Yea, I mean a new wireless card is only $30 but I love learing more technology, its my line of work as well... just in a different area. I like to fix things like this to learn. Any tests I can run tomorrow to give you more insight?

simple. wire a pc up to the wireless router.

open a web-browser and go to your default gateway adress (something like 192.168.0.1), this should be the firmware for your router. go to something like "wireless networking" in there should be a security/encryption type.

write that down.

then go to your wireless networking options in windows 7. go to Control Panel\Network and Internet\Manage Wireless Networks, in there your local network should be listed, on that page should be a "security" column. make sure that info matches the settings in your modem (if the modem is WPA2, make sure your local wireless settings are also WPA2)

thats what i want you to check.

I actually did this already. The settings on the security on the router is WPA/WPA2 Mixed Mode. I don't have that option on any of my computers. My laptop setting is WPA-Personal so I tried that on my desktop as well, to no avail. Sorry to run you in circles.
