    Are you using a USB HSDPA/EDGE/UMTS 3G Modem on pfSense?

      Is there some sort of GUI that shows signal strength from 3G modems?

      For some, there will be RRD graphs with signal strength. For the UM175 in particular, we have a utility that pulls those stats and is supposed to be graphing it via RRD, though it has a problem at the moment. It was just fixed in the builds so tomorrow's snapshots should be ok.

        btw, it is very stable with the UM175, I wouldn't hesitate using that in production now. Mine gets great throughput, and since it was initially implemented and everything fixed early this year, never had a problem with it, always been rock solid. We have some 2.0 boxes in the field in production with UM175 cards.

          What is the utility? I'd like to add the capability to get stats from the C885 and the E169 and whatever else I can get my hands on. :)

            I found the utility. It doesn't look easy to extend to other devices, at least by me.

            Now, hijacking my own thread, I know . . .

            I've been thinking for a while about creating a (much simpler) tool to send a query to the diagnostic serial ports on a 3G modem to get the signal strength. I think AT+CSQ is a standard query and all the modems I've encountered support it. However, I wasn't planning on doing an historical graphing, just displaying current signal strength. This is from my Sierra Wireless C885
            –----------
            at+csq
            +CSQ: 20,99

            OK

            Here's a graph relating the CSQ # to dbm of signal strength. http://www.gprsmodems.co.uk/images/csq1.pdf

            I've testing using just
            #echo at+csq > /dev/cuaU0.3
            #cat /dev/cuaU0.3

            but the trouble is that the C885 modem never sends a character that makes cat finish catting if you know what I mean. Cat just sends an endless repeat of the same data from the serial port to the terminal.

            So . . . a slightly more sophisticated program is necessary to send the query to the serial port and get the response back. I thought it could be a command line program that could take the device and the command as arguments. (I would have done it already, but I don't have enough experience with unix programming in C.)
            Another upside is that this same program can be used to query the modems and automatically set  up the serial ports for the users based on the device type. Whaddyathink?

              It's not, Andrew Thompson who wrote that for us (as well as a number of the 3G drivers in FreeBSD) said each vendor has a different way of doing that. Checking with him on the feasibility of at+csq. He could adapt 3gstat to pull that without a whole lot of trouble I think.

                Has anyone tried either one of these two MiniPCI Express modems?:

                • Novatel 5520 Mobile
                • UMTS/HSDPA Sierra Wireless MC8775

                … with an Alix6B2 board?

                I know a bunch of USB modems would work, but I can't use one of those for this deployment. It will have to be an "embedded" module.

                I'm considering getting all the hardware to do some testing, but if possible would like to know which modem to get.

                Thanks in advance!

                    I',m using Alix board with Huawei E220 working verry good.

                    Last days I'm trying Vodafone k3765 USB stick, it has 7.2Mbit support, but doesent work with latest pfsense snapshot :(, I hope that this modem will be supported in future, becouse its much smaller and plugs directly to USB port it getets detected by the system but log says that modem does not respond to AT command?i

                    regards,

                      Yes, not in Canada, but the cards are the same regardless of where you are.

                        Yes, but like cmb's reply, not in Canada. I've successfully used a Huawei E181 USB (GSM/WCDMA/HSDPA) stick with pfSense 2.0 BETA4 on the T-Mobile USA's network. The Huawei E180 should work too since it is has the same firmware as the E181, with the only difference between the two models being the WCDMA frequency bands they support. Chances are that many/most other Huawei modems will work too, but I have yet to test that.

                          Is this supported in version 1.2.3?
                          Can it be used as a backup or in load-balance mode with a DSL PPoE?

                          Thanks

                            I haven't tried, but I don't think so. I think it would require loading drivers for those cards. In 2.0 it pretty much just works.

                              No and yes.

                                Any plans to get it working with version 1.2.3.

                                By the way, when would version 2.0 become stable?

                                Thanks

                                  No, and sometime this year.

                                      What version of pfSense are you using? And what's the model number of your Huawei card? If you are on v1.x.x, chances are it won't work without a lot of hacking, or at all. Try upgrading to 2.0 BETA and it may work out of the box. However, beta is beta …

                                        Successfully tested T-Mobile webConnect Rocket, aka Huawei UMG1831, an HSPA+ modem with pfSense 2.0 BETA4. Got very low speeds up and down (despite it being an HSPA+ card), but my coverage was really bad so that was most likely at least part of the problem.

                                          Also tried a miniPCI express card, Huawei EM770U, and got the following message during boot:

                                          ugen1.2: <huawei technology="">at usbus1
                                          u3g0: <huawei 0="" 2="" technology="" huawei="" mobile,="" class="" 0,="" rev="" 2.00="" 0.00,="" addr="">on usbus1
                                          u3g0: Found 6 ports.

                                          So, I'm guessing it should work … but I can't get it to connect.

                                          If anyone has any ideas, I'd be grateful.

                                          Thanks in advance.</huawei></huawei>

                                            This suggests the modem is recognised by the u3g driver so it should work Did you follow the steps in the documentation at http://doc.pfsense.org/index.php/Configuring_3G_modems
