Says that it is compatible but I need to check USB ID, I was hoping someone would be able to tell me what that is and how do I check it. Did a search here and found post from 8/17, saying that Meraki said this model just wasn't supported. Need to replace some old ones that died and need to stick with Verizon. Any recommendations would be welcome but getting to ok to order anywhere other than Verizon will be uphill battle.
Do you have a spare WAN port on your MX100/MX65? If so, get a 4G router instead, and just plug into the MX WAN port via Ethernet instead.
Spare WAN on only about a third of the sites, which is where the problem starts it seems.
If you have a Linux machine handy you can check USB ID's with the 'lsusb' command. I don't know if there's away to do it in Windows.
I am looking to order them and avoid the exchange policy, and no, no linux.
For anyone else looking into it, ordered from Verizon, working fine.
