The HM indicate it’s a E3372h whereas SM would mean it’s a E3372s.Īll Hilink firmwares use a 22.x version number. The stick I bought carried the following version information: Model codeĮ3372 h: Apparantly sold with Hilink firmware, E3372 s: Apparantly sold with stick firmware (but see below)Į3372x- yyy: Apparantly a region-specific code, couldn’t find its exact meaning however However this process can get a bit cumbersome as quite a lot of information on the Web is incomplete, outdated or in a foreign language. a Hilink firmware stick with a Stick firmware and vice versa. It is, luckily, possible to flash a stick with the respective opposite kind of firmware, eg. Unfortunately you can’t see from the outside whether you get a E3372h or a E3372s unless you can slide the stick’s cap off to access the SIM slot (see the gallery). Hilink mode is practical for most users because they likely need no special drivers to use the LTE stick but it’s disadvantageous if you want to provide services to the Internet. Sticks that come with the stick firmware seem to carry the model code E3372 s-xxx (but see below).

In this mode the interface created exposes the IP address assigned by the mobile network directly, ie.

with a “Stick” firmware (version numbers 21.x) the stick appears to the USB host with two USB serial devices one of which exposes an AT-style interface over which both PPP (slow) and NCM (Network Control Model, part of the USB implementers forum Communications Device Class (CDC) class of protocols for providing Ethernet-over-USB style networking, faster) modes can be employed.

Sticks that come with the Hilink firmware seem to carry the model code E3372 h-xxx. This also means it will do the network address translation (NAT) for you and has some sort of firewall, which, at least in the version I had (see below) was not configurable at all.

with a “Hilink” firmware (version numbers 22.x) the stick appears to the USB host as an Ethernet device, runs an own DHCP server and provides a Web interface at the IP address 192.168.8.1 to control its router operation.

The bad news is that the E3372 comes in one of two variants: It features a LTE Cat 4 modem supporting up to 150 MBit/s download and up to 50 MBit/s upload speeds, falls back to (DC-)HSPA(+), UMTS and EDGE, if necessary, and has quite small dimensions (88m x 28mm x 11.5mm). “Telekom Speedstick V”, “Megafon M150-2”) and rather affordable (currently starting at €60 in Germany). The Huawei E3372 is quite a popular LTE stick: it’s widely available (in retail stores, on eBay and also in branded variations, eg.
