Is Your Integrated Verizon WWAN EVDO Working Under Vista?

[shfawaz]

Ok, so I've posted my problem under two other EVDO threads only to come up empty handed. I know there are several users here that have successfully installed and are running their integrated WWAN EVDO cards under Vista. Question is, why won't Vista recognize or pick up the drivers for mine?

I have a MC5720 modem listed under other devices with an exclamation mark. I've tried every solution offered in the other threads to no joy. Can anyone here post the drivers they are using to make this work? I've pointed and downloaded every latest driver from Lenovo and Verizon including VZ access and Vista simply refuses to recognize any file or .inf as the correct one and it simply fails to install the driver. I know these cards tend to load a network and modem driver, but I'm at a loss to figure out how to get Vista to install the respective drivers.

Any suggestions, ideas (other than reformat) would be appreciated. I've moved the hard drive to two different T60's and an X60 with WWAN and the same thing happens, so I know it's not hardware, especially since the drivers and cards work under XP.

I got mine to work finally. I took a few attempts. End up installing the WWAN driver from Lenovo site after installing some other required components. Installed AC 4.3 as well after and card seems to work.

The major issue is the state of the driver does not seem to resume after stand-by, i.e. the card does not work and cannot be turned on without rebooting the PC.

Anyone having similar issues?

After a frustrating hour on the phone with IBM tech support with a guy in Atlanta whose first response was "Why would you even think about loading Vista????" Pretty much thats how the following attitude proceeded for the duratrion of the alleged troubleshooting session.

He asked me the common questions and I affirmed that I had done every trial remedy he had asked about, he put me on hold for about 25 minutes only to come back and say this was being escalated since he did EVERYTHING he could to help (in my humble opinion-he did literally nothing) but complain about the cold. I should expect a call back in 72 hours. Still waiting.

I finally decided to pull the hard drive from a second Thinkpad that I had loaded Vista on where the drivers for the WWAN card installed without any problem, and I put it in the Ultrabay slim adapter. I tried once more to have Vista load the drivers, pointed it to the program files/Sierra Wireless Directory and lo behold the drivers took and the WWAN! Amazing!!

It turns out every time I tried to run the .msi file for some it wasn't extracting the usbmux directory that contained the .inf files.

Anyway, I'm glad that nightmare is solved, and my Verizon WWAN is working like a charm!

IS your card working after the computer wakes up from stand-by. Mine does not and I need to reboot

Mine works fine under Vista. Works after coming out of standby just fine.

I didn't try EVDO until the Lenovo drivers and Vista-compatible Access Connections were released, but with those I have (for some reason I can't fathom) had no problems at all. It just started working without my even having to do anything to get Verizon to re-recognize my system.

Those of you who have problems with the WAN radio working after standby or hibernation should try turning the WiFi/Bluetooth/WAN radio button on the left center front of the bottom of the machine off, waiting a second or so, and then turning it back on. This works for me.
