WLAN Card Update - Lenovo

[slamothe55]

Hey guys,

So I have a B50-45 Lenovo laptop with Windows 7 installed.

I tried upgrading the WLAN card to a card that is on the whitelist for this device (FRU 20200579) via this page here.

But when I put it in and rebooted, it said "unauthorized wireless network card is plugged in. power off and remove it"

Any idea why?

Thank you!

Did you try downloading from this driver page?

If that doesn't work, try this one:

Yes when it starts to install it gives me message "No Appropriate Driver to be Installed"

Same message from both links, sadly.

It really makes no sense. You could try some of the driver sites out there, but I don't really trust them. You might try starting another thread in the Windows 7 forum to see if you can get some help doing a force install of the driver.

Thank you I appreciate all the help. I will try and do that.

Ahh man I cant catch a break, now whenever I close the lid and it goes to sleep and I wake it up, i get a blue screen with error code 0x000000F4

Any idea what could cause this?

I also get this real quick on bootup, any idea?

The PXE message at start is probably because you've got your network card specified as your first boot device. It's not really a concern, but slows your boot time down by several seconds.

The second message (STOP 0x00000f4) indicates that a critical system process or driver has crashed. That'll be tough to troubleshoot, and I'd probably have to point you to a local tech. The first thing to do, though is to try and undo whatever changes have been made. That means removing the wifi card and replacing it with the old one and see if the crashes go away. You might also need to do a system restore to an earlier time before you made changes to undo any driver changes that happened while you were trying to get the wifi driver to work.

Try taking out the new wifi card first and see if that fixes the BSOD. If that doesn't work, then try a system restore to a few days back.

I actually fixed the PXE message shortly after posting that in BIOS by changing the boot order back, not sure how that happen. Thank you.

As far as the BSOD, I have put the original card back in and also did a system restore and neither seem to have fixed the issue.

Its not even worth bringing to a tech, the computer is not worth that much. Was just hoping to increase internet speeds with the new card, but looks like I will have to do a fresh install of windows 7 and use the original card. Not sure I have many other options at this point.

Thanks again for all your help.
