Panasonic Toughbook CF-53 MC7750 4G Verizon Issues – 2101 Error

We have a few new Toughbook CF-53’s in that occasionally get the 2101 error within Verizon Access. I was wondering if anyone else was having these issues? I am in touch with Panasonic, and Verizon on trying to get a permanent fix, but it seems to be very intermittent right now.

If I get a resolution, I will update this post.


OKAY, so I have two CF53’s with the issue. Been contacting verizon with no luck, finaly got a hold of the Panasonic wireless engineer and he shared with me some new software specific to these MC7750’s, and specific to this 2101 error. Basically what was happening was that the driver software was installing some connect option for Windows 7, it would sometimes install and conflict with Verizon Access Manager. So what he did was remove that from the installer, and bingo, worked like a champ…tried this one two laptops with error 2101.

Software :

Drivers from Panasonic: linky
Software from Verizon: linky

Make sure to uninstall all old drivers, and VZAccess Manager and then install the new ones.

Any questions let me know, I will try to assist.

I just wanted to say thank you! My company just pushed out 100 of the CF-19 toughbooks which use the same modem and driver as you do. I spent countless hours talking to Verizon and Panasonic with nothing happening. Then i found your article and it was the same exact issue. I just updated 5 toughbooks and they are all working fine now! 🙂

For if anyone else sees this I was having issue where sometimes i could connect to the wwan for verizon 4G and sometimes it would error out 2101. Rebooting the laptop would most of the time fix the issue, sometimes it would take 2-5 reboots. This fix takes care of it all, it now works like its suppose to, thank you again for posting.

I am glad this resolved yours, and I was not the only one with the MC7750 go 2101 on me either! I have the fix on about 25 CF53’s and so far they’re rock solid.

This also seems to have solved my problem with 17 CF-31 toughbooks I was about to deploy all over the state and this would have been a killer problem!

Hello, I am having same issue and tried to click on linky for download but it doesn’t let me down load, please help.
