Hi Dairyman, thanks for taking the effort to join this forum and provide support for your great initiatives. We're grateful that you and Wahroonga Farm coming here to further enhance our experience with these awesome affordable routers from TP-Link.

I'm looking forward to having the capability of doing modem related stuff directly from the web interface.

hey WF and DM.. u can always count on us as testers... hahaha

Glad to be here. We have found the TP-Link routers to be cheap and reliable and, with the new firmware, a great piece of hardware for 3G/4G usage.

I have found the AT Command to set a Huawei modem into 4G mode. It is :

AT^SYSCFGEX=03,3FFFFFFF,2,4,7fffffffffffffff,,

This will set it to 4G mode with band selection automatic.

Use ModemGUI in the Custom Command dialog to execute this command.

A new version of the fast 3G/4G OpenWRT with Modem GUI is available.

26022013 –
New 'modem support' and 'information' tabs so that the user may add an unsupported modem or modify an old one.
Fixed mismatch of protocol and driver for the MF6XX family.
***New MR3220 V1 and V2 firmware***.
Note: It is safe to 'keep configuration' when updating to this version.

WIKI, Dairymans "Of Modems and Men"

I've been following the last couple of pages silently and I'm very excited with the new firmware. Special thanks to DairymanCanada & Wahroonga Farm

Upgraded from 20022013 to 26022013 without a hitch.

I'm using an e353 modem and it works just fine connecting to the internet with the router (MR3420 V1).


...but I couldn't get it to work with ModemGUI. When I click "Connect" the window sometimes goes to "Not Responding" but still connects.

OpenWRT System Log:


ModemGUI seems to connect with the router but I waited for 10 seconds (and longer) but all the info is 'Unknown':

Clicked on 'Disconnect', waited for a while, all the buttons remains disabled (including the Exit button). So I had to quit via the X button.

OpenWRT System Log:


Enabled "Debug Logging" but after exiting (X) Log.txt only shows:

From memory the E353 uses Port 1, so try selecting the 'Modem Command port'; rather than auto, which uses Port 2.

Edit: Hmmm.

Just checked a captured image. My E353 ran ok on auto it seems.

I did try Port 1 previously but it said "Modem Not Found". Nonetheless, tried using Port 1 again, and it works!



edit: Tried Automatic again, same thing, no info. Had to force exit (x). Then tried Port 1, error "Modem Not Found". Tried Port 1 again, then it works.

One thing you have to make sure of is that the modem has finished connecting before you use ModemGUI. Don't attempt to use it while the modem is still working on the connection or really strange things can happen.

This is caused by several AT Commands being sent to the modem from different sources (connection script and ModemGUI) and they conflict with each other. Guaranteed to cause a program crash.

I have found that for some things, like SMS, you have to stop all other AT Commands from being sent to the modem or the program crashes. Actually it sits waiting for a response that got funneled off to another process and gets locked in a waiting loop.

FYI, Automatic is just ttyUSB1. Long boring story as to why this so I won't relate it.

One other thing that may be happening here. WF was probably using the PPP protocol when his image was taken. That was the original setting for the E353. You are using QMI since the firmware was changed to support this for the E353.

What can happen (it does for ZTE modems) is that using QMI changes the command port from that used in PPP. For the MF668 the command port in PPP is ttyUSB2 and using QMI it is ttyUSB1.

You sometimes have to experiment to find the correct port.

Hi.

I need some help.

I need help for the indicator signal 3G/4G.

I downloaded this: http://ecco.selfip.net/attitude_adjustment/ar71xx/packages (3ginfo_20130214_all.ipk)

uci set 3ginfo.@3ginfo[0].language=en
uci commit
3ginfo

or

/etc/init.d/3ginfo start and see http://192.168.1.1:81

Insert the command in Putty above, but without effect.

It's the first time I use OpenWRT firmware. I'm new in these things.

Best Regards

An update of Dairyman Openwrt package is available.

02/03/2013 – Minor bug fixes (e.g. script date) plus major features.

+ PAP and CHAP authentication.
+ 'Keep connection alive' (like Dovado) with a choice of 'disabled', 'just ping and report' or 'ping and restart WAN' if disconnected.
+ Additional support for the E3276, (no user added support required).
+ USB (powered) hub support.

Note: The Keep alive function pings 8.8.8.8 every 2 minutes and waits up to 10 seconds for a response. If Enabled then it logs a message stating the connection is down or that it is alive. If Enabled and Restart then it will log a message and restarts the WAN if the connection is down.

Hi,

Dairyman is investigating the possibility of incorporating some of the features of '3ginfo' into his Openwrt package.

Cheers

Thanks alot for your work bro. We are very happy with the firmware.

Bug report
I figure out that we unable get connect in DC-HSPA+. Is that anyone seen DC-HSPA+ with aircard 320u before ?

You are probably getting DC-HSPA+ but ModemGUI is not reporting it correctly. If it finds HSPA+ in the network type it assumes it is HSAP+ and not DC-HSPA+.

I'll correct this problem in the code.

Other modems will also have this problem and will need to have it fixed.

Thanks for the bug report.

HI,
Is that we can check system Log in router there to ensure whether it is DC-HSPA+ or HSPA+ ? Let just me know if you need any info to fix the bugs .


Thanks and have a good days

If you have the Signal Log activated (box is checked) in ModemGUI you can look in the Signal.log file (a text file) and see exactly what was returned by the modem. I just seen another log from a 320U that shows a DC-HSPA+ network in the log file.

Just report any thing that doesn't look right to you and I'll see if it is a bug and will attempt to fix it. I have fixed this for ZTE and Sierra modems and am currently finding a fix for Huawei modems.

DairymanCanada can you make your firmware support mr3420v2?

Hi DodoBird 23,

Dairyman will provide a V2 image when the OpenWRT official image is available.

It is expected soon (although we've been saying that for a while now).

We will test it before release.

Cheers

i have 3420 v2,,how to add openvpn,,? without extroot,,ty

after flash to open wrt, my tp-link mr3420 unable to detect the correct location already...

before this with the stock firmware, it able to detect the current location.

For example, with stock firmware, in Puchong, my iPod Touch able to detect correct location, mind that iPod Touch doesn't have GPS and it detect location by using the connection that it connect

even in Cameron Highlands also, it can detect the correct location..

but, after flash to open wrt, itmy iPod Touch] unable to detect the exact location, it still stuck at Cameron Highlands[I flash my router at Cameron Highlands]


but when go to free WiFi McD, it able to detect exact location[McD itself]

so, it is the modem/router problem, and not the iPod Touch problem...
so, how to fix this?
