[j-nsp] 3G/4G on SRX

[Ben Dale]

Hi Jeff,

To use the USB port on the branch SRX 100,110 or 210 as 3G/4G backup you need a sierra wireless modem.

There are very few listed on Juniper's supported list, but at least here in Australia I've found that most available Sierra 3G modems tend to work including:

USB306
SW312U
AC326U
AC310U
SW319U

4G is a different story thanks to new chipsets/drivers and only the Sierra 320U seems to work.

Depending on your carrier and the frequency that they operate at, you should be able to pick up unlocked SW cards on ebay or aliexpress pretty easily, then just drop your SIM in.

The alternative is grabbing a Juniper CX111 wireless bridge (which is a Cradlepoint CBA750 OEM) - they support a much bigger range of cards and will work with pretty much any router.

Choose CBA750 in the Select Your Product menu on the right and you'll get the complete list:
