This modem won't connect, and I get error message WMC671, and cannot find what this means
I may have stumbled on the fix for the error code WMC-671 with the VL600 USB Modem.
I like the rest of you have been plaqued with the error code WMC-671, dropping connections, automatic reconnections with high noise levels, etc ... I have done all the things that everyone else has done and gone through the ordeal with the two levels of tech support and got absolutely no where.
Today I got a message on my computer saying that my connection was public on my desktop PC. So I went to the control panel under HomeGroup (Windows 7) and changed it from Public to HomeGroup. Ever since I have done that, for whatever reason, I have not experienced the problem anymore. I'm not losing connections nor getting the error code when trying to connect. I don't know if it is just a fluke but if it is I will accept it. If it is not and it helps others, great.
Just wanted to share the info and hope you have the same results.
TRY THIS::: PUT THE PC IN STAND BY OR HIBERNATE MODE 5 SECONDS THEN TOUCH THE TURN ON BUTTON OPEN
VZ AC. MGR CLICK DETECT DEVICE
Try removing the device, then wait 5 seconds and reinsert the device.
If problems persists:
Try rebooting the the PC.
This does not work. I have the same error code regardless of what I tried. I have go far as to wipe the computer and reinstall Windows 7 Home Premium and then installed the Verizon software - same error WMC671
Almost forgot - I also contacted Verizon tech support, they could not resolve the issue so I was "escalated" to some group specifically for 4G - they could not figure out what the error code was either. I was told they would contact me back after some research. that was December 17th. I still have not heard from them. They did provide a ticket # though?
I've had the same problem ever since I got the G. It is sporadic with no pattern that I can see. I keep trying or sometime have to reboot. Would be nice to get a real explanation. NEVER had any trouble before getting the G.
The error code WMC671 usually means there is a problem with the USB device. It could be a power consumption issue due to conflicts with power management settings or a dormancy issue. Usually closing VZAccess Manager and then removing and re-inserting the USB device will correct the issue. If the issue is not corrected after that a reboot of the computer is recommended.
Well scratch everything I said as I just had a failure so it was just a fluke that it lasted so long. But I think I can say with some confidence that the 4G VL600 modem is a piece of crap. Never had a problem with my 3G USB 760 modem.

You have to make sure your computer is plugged in to the wall. A lot of computers have a battery saving mode that disables some of the network adapters for power comsumption, make sure you change the settings for the future but after you plug in your computer to the wall you might want to restart VZW or your computer and it should work again. It's a computer issue not your verizon wireless modem.
Had the WMC671 error code for the first time this morning after almost two months of use. The modem would not work in either my desktop or laptop. I figured it must be a modem problem so I took it back to the store and told them the error code. After some consulting with the resident 4G tech, I was told it was a network problem they were experiencing affecting only 4G devices and would soon be corrected. After I returned home some time later I tried the card and it worked fine. So, evidently it sometimes is the network.

I've tried the LG VL600 on two computers, one a laptop running Windows XP, and the other a Toshiba Netbook running Windows 7 Starter edition. Everytime I've tried I have had the computers plugged into AC from the wall, never running off of battery. I have tried all 3 USB ports on both computers, and everytime I've gotten the "Error WMC671" error.
I just uninstalled the VZ Access Manager software completely (and the drivers), rebooted, and reinstalled the latest version of VZ Access manager that I just downloaded from the website (and confirmed it was the latest by doing the "check updates" and got "you are running the latest version"), and I still get the Error WMC671.
I have NEVER gotten this modem to connect on 4G, 3G, or any cellular network.
This issue is most definitely NOT "solved".
It sounds as the stance VZ Wireless is taking is that it's not their problem but ours.
We can either spend countless time reconnecting and rebooting or change providers.
The overall support from VZ wireless has been terrible lately. It's time to move.
In my case, I had to call tech support. The 4G card I had upgraded to did not get activated. They took off the older card, activated the new one and it worked. Hope this helps someone.
Hey Edgarsdroid!!
You are WRONG! It is network all the way! These 4 G USB Cards do not work!!!
I just solved my LG VL600 WMC671 problem. Check with Verizon and make absolutely sure that the VL600 IMEI number on your receipt or box barcode and the SIM card ICCID number on your receipt or SIM card package are correctly setup in Verizon's computer. Mine weren't and the device did not work. Once Verizon corrected them, the device worked immediately. Good Luck.
