Meraki Router + AT&T Aircard Question

by Jake139 / February 4, 2014 8:19 AM PST

Hi -- I've got a Meraki MX60W and need to get a USB Aircard for a 4G connection. In the devices Meraki lists as compatible for AT&T, the Neatgear Aircard 340U is listed. It doesn't seem to be for sale most anywhere under this name but instead as the "AT&T Beam." They appear to be the same product but the lack of continuity with the names is a little disconcerting.

We've had some trouble with compatibility between Meraki and other devices in the past and wanted to see if anyone has used these two devices together successfully. Any help would be great. Thanks!

Hi Jake,

I actually just got off the phone with Meraki about this same issue. It works, but there are a couple caveats.

First, you need to be using the beta firmware on the MX60- If you call Meraki they can push it onto the device for you.

Second, you have to change the firmware on the AT&T Beam modem itself- I'll paste the email from Meraki below which contains the instructions for this.

Once that was done, the device successfully connects to the AT&T Beam, and fails over to it when I disconnect the WAN. I am still having issues with VPN though that I'm going to talk to Meraki about. When its failed over, the VPN status page shows that the MX60 is behind a VPN-unfriendly NAT, and shows the connection status as disconnected. I had the device initially set to establish a VPN connection to all other devices in my network, and interestingly some devices connected, but some did not. Among those that did not was the device in my data center, which is the important one for me. I switched to hub-and-spoke mode and attempted to connect only to the data center device (an MX80), and it still would not connect Sad I'm sure this is more an issue with my network configuration than with the device though.

Heres the email from Meraki re updating the AT&T Beam firmware. Note the warning in step 5:

[quote]Kenneth,

Please follow the below directions in order to get this modem to connect to the MX60 sucessfully:

The device itself must also be patched to disable Windows 8 mode and allow for auto-connect. This must be performed on a Windows PC.

The patch is here:https://www.dropbox.com/s/px2nule27mbwc3b/AC340U_linux_patch_v4_S08511.exe

To run the tool on a Windows 7 PC:

1. Install the necessary drivers on your Windows PC (if not already completed)

2. Insert device, make sure no AT&T or other connection manager is running.

3. Execute "AC340U_linux_patch_v4.exe"

4. After the tool completes, you should notice your device reset & connected status on the LCD.

5. Note that this change will turn OFF Windows 8 native MBIM support, so please consider this when you make your update.[/quote]

VPN-unfriendly NAT
by Nacelle02 / December 10, 2014 7:31 PM PST

Hello Kenneth,

I have just come across this post and have very similar issue and wondered if you managed to solve it.

We also get the VAT unfriendly NAT when using Z1 and 3G / 4G to connect to the MX at our Data Centre but the tunnels to other Meraki are fine between the Z1 and others.

I to think is an issue with my D

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
