Windows 7: wireless wep can't connect in x64

20 Mar 2009   #1

Windows 7 x64 and x86
 
 
wireless wep can't connect in x64

I have both x86 and x64 Seven installed. Wireless Card is Realtek 8185 b/g, router is belkin 802.11b

For x86, 7000-7048-7057 all connected to the 802.11b router with WEP 128bit without problem.

Since 7057, I installed x64 Seven and verified that the WEP key is correct. But, it just can't connect. "Unidentified network", Access type: No Internet access. ipconfig/all tells me that I didn't connect to the router at all. The router's dhcp didn't assign the x64 any ip.

If I boot up the x86, I then can go to internet without problem.

I tried the troubleshoot. The program reset my wireless network card then let me retype my wep key. At the end, it was unable to fix the issues and it lists the problems as below:

Windows cannot connect to "....." Detected
"Wireless Network Connection" doesn't have a valid IP configuration Detected

Now, if I manually set a valid IP "192.168.2.3" and mask "255.255.255.0" and gateway "192.168.2.1", I still can't connect to the router. But, from the router side, the dhcp list shows my x64 ip address.

Also, even if I reset the router to Open (without WEP), x64 still can't connect to the router. None of above can make me ping the router. So wired...

Please help me. I do like x64 over x86, because in there the office2007 and SAS 9.2 won't freeze/without response. And, I don't have the lan access to the router. It's shared with my friend in downstairs. Thank you.

Windows 7 x64 RC build 7127
 
 

I have exactly the same issue, running on this for a week now, tried all kinds of solutions, to no avail yet.
I have a Realtek card, and an Edimax router. The other machine is a XP SP2 and connects fine. And the Seven machine also connects fine through the wired connection. It is going kaput on the wireless thingie.

When troubleshooting and letting Windows trying to repair, it doesn't work and says something like that I haven't got a valid IP configuration.

I tried:
- disabling IPv6;
- formatting and updating from build 7100 to 7127;
- manually assigning the IP addresses/subnet mask on IPv4;
- updating the card's driver;
- removing and reinstalling the card;
- changing the registry according to http://support.microsoft.com/kb/928233;
- removing from the Homegroup;
- updating router's firmware;
- unchecking the energy saving feature of the card;
- changing the encryption from WEP to no security on the router;

It connects, but status for a long time keeps on "identifying..." and when connects, it says "Local Access only". When it connects it says it is an Unidentified Network (Public Network).

I'm clueless.

Hey, I found that it is not a windows 7 x64 problem. This problem happens in every x64 system. I tried winxp x64, vista x64 also. They all have this problem...

Seems WEP and x64 not sync....

I don't have a problem with open network though.

Hi,

For me it is still not working, even with open network. I tried both WEP and open.
Maybe it is the router, an Edimax BR-6204WLg, but I'm not sure yet... Maybe it is not able to handle the packets Windows 7 send and is not assigning an IP address to the machine, don't know. I tried every idea I had on the workstation end without any success.

Gotta try with Windows x86 and see what happens. Maybe it is a 64-bits issue.

Still searching, though.

Thanks,

I've been in contact with my router's manufacturer (Edimax) tech support and in their reply they told me - without me telling them which my NIC was - that it is an issue with the Realtek 8186 - which I assume is from the same family than 8185L - chipsets on Windows Vista and Seven.

Their instruction was to set a manual IP address, which I did. Didn't work, though.

The sad thing is that I'm using the drivers provided by Microsoft through Windows Update to no avail. I'm gonna try other drivers, maybe one of them should work. Anyone here got into the same trouble as I?
RTL8185L vs. Windows 7 64-bits? Which driver is the best (working) one?

Hi, RAF2

Thank you so much for your effort! I got luck this time!

I went to realtek official website, downloaded Winxp x64 driver and Vista (both x32 and x64) driver. Updated my driver to the Winxp x64, bang, done. I am using it right now! Thank you so much!

I also tried Vista x64 driver, this one didn't work for me. So, good luck! It is a problem of realtek driver...

Hi, cwzkevin,

Very glad you got your problem solved!
Can you please be more detailed about the drivers used and how you proceeded to update it?


Yesterday night I tried to use WinXP64 drivers on the card, went to Device Manager, chose "Update Driver...", typed in the path of the driver, and Windows 7 didn't let me update it, saying that the current driver was the most up-to-date and the new one wasn't needed -- I hate such kind of actions on its own, at least I could be asked if I was sure.
So I tried a new approach: went to Windows\system32\drivers and replaced the RTL85n64.sys file by the one from XP64 renamed. Disabled and reenabled the adapter, but didn't work. Maybe I'm using a different driver than you.

I tried Vista64 drivers also. Tonight again I'll sit at the front of the computer and want to solve it definitely. I hope I get luck tonight.

Hi, RAF2

So, Device Manager, the Wireless Card, Update Driver, Browse my computer, Let me pick from a list, Have Disk, then locate the unpacked folder of WinXP64

About the driver, Realtek
the second line, Windows 64-bit driver, version 1105 is the one worked for me

So, good luck tonight!

Hi, cwzkevin,

Thanks! I'm still at work now, I shall give a go tonight on your recipe.

I guess that the way you showed there are no problems with Windows 7 preventing you from changing the driver saying that "the current one is the most up-to-date and there is no need to update the driver". This self-decision really annoyed me yesterday.

Here we go, later I'll come back here with news. Thanks once again.

Ok, now it is working!

I'm using a Windows XP 64-bits driver. That one cwzkevin recommends above.

On the first go, it installed fine and started but stopped working a few minutes later and causing the system to stutter periodically. I believe it was due to the system sleep, maybe the driver wasn't able to "wake up" the adapter together with the system, since it wasn't listed on the adapters list anymore, which was showing only my onboard LAN adapter. And the stuttering was periodic, with a little CPU activity (30% or so) on svchost.exe together with it. It was annoying.

Rebooted and replaced it by an actual 7 64-bits driver, then installed again the XP 64-bits driver. Just to be safe, I disabled the other NIC (onboard wired) to avoid any conflicts and turned off the "Allow the computer turn off this device to save power" option, under the Power Management tab.
I left the computer running/sleeping overnight and now, at the morning, no stutters, everything is still working at full speed and good signal strength.

I haven't rebooted yet, will do so in the next few hours. I'll post back here if any problems are to be reported.

BTW: does MS tech guys read this forum? If so, we must tell them to remove that driver from Windows Update and use the XP 64-bits instead.
