Configure D-Link DIR-320 / NRU + 3G Rostelecom R41 (Sense R41)
The article describes the configuration of the D-Link DIR-320 / NRU router and the 3G + Rostelecom R41 modem.
The router support page lists the compatible models of modems, and “3G + Rostelecom R41”, also known as “Sense R41”, is not included in their number. When connected to the router, the modem is not defined in the configuration interface, it is displayed in the logs as a SCSI device, and no / dev / ttyUSB * devices are created. That is, without options, an alternative router firmware is required.
An Internet search revealed that this router can be flashed with some versions of ZyXEL Keenetic and OpenWRT firmware. The choice fell on OpenWRT. Along with the custom builds of OpenWRT, which include everything needed to connect a 3G modem, support for the DIR-320 / NRU router has been added to the main OpenWRT branch, starting with revision 38040. Therefore, the latest stable version of OpenWRT, Barrier Breaker 14.07, is selected for the firmware.

All subsequent actions concern routers with hardware version B *.
He is "Sense R41", he is "Network Connect R41"
You will need the curl and ssh utilities. On Windows it is convenient to install MSYS2 and install the curl and ssh packages.
Download side OpenWRT for DIR-320 / NRU. At the moment it is the latest stable build. Or you can search for other releases / builds with the ramips / rt305x / openwrt-ramips-rt305x-dir-320-b1- prefix . Copy the firmware in the folder Dir320 .
Comment:
Create a script in the Dir320 folder:
We configure the network interface on the computer:
Turn off the power of the router. We connect the network port 1 (or 2, 3, 4, but not the INTERNET) of the router with an Ethernet cable to the configured network card (192.168.0.10).
Run the script Dir320 / update_flash.cmd and execute the instructions it displays . Namely:
1. Watch logs - Kernel Log
Via web-interface: Status menu → Kernel Log
Via console (ssh):
There should be entries like this:
Keywords - usbserial , ttyUSB * .
If they are not there, then make sure that all packages are delivered: System → Software menu or a command in the console.
Make sure that in /etc/hotplug.d/usb/22-3g_dongle the idvendor , idproduct , bcddevice parameters match the USB device. This can be viewed in the console with the command
Something should be displayed.
The first three lines correspond to the modem.
2. Next - System Log
Via web-interface: Status menu → System Log.
Via console (ssh):
There should be entries like this:
If the connection fails, you need to look at the error code. Without this, more specifically, nothing can be said.

2. Preparation
You will need the curl and ssh utilities. On Windows it is convenient to install MSYS2 and install the curl and ssh packages.
Download side OpenWRT for DIR-320 / NRU. At the moment it is the latest stable build. Or you can search for other releases / builds with the ramips / rt305x / openwrt-ramips-rt305x-dir-320-b1- prefix . Copy the firmware in the folder Dir320 .
Comment:
To configure the router, you need additional OpenWRT packages. The easiest way is to set up a WAN on the router (Internet through an ISP cable) and install packages via the Internet. It is possible to download packages in advance, as well as build packages into an assembly or build firmware from source codes with added packages. But I did not study this question. Details on the OpenWRT howto page.
Create a script in the Dir320 folder:
update_flash.cmd
Comment:

Change the line set firmware = ... - set the name of the firmware file, if you called it differently.
We configure the network interface on the computer:
IP: 192.168.0.10 Mask: 255.255.255.0 Gateway: 192.168.0.1
Turn off the power of the router. We connect the network port 1 (or 2, 3, 4, but not the INTERNET) of the router with an Ethernet cable to the configured network card (192.168.0.10).
3. Firmware
Run the script Dir320 / update_flash.cmd and execute the instructions it displays . Namely:
- Clamp the Reset button on the router with a match / paperclip / pencil.
- We connect power to the router.
- We are waiting for 10-15 seconds.
- Release the reset button.
- We are waiting for 2-3 minutes.
4. Configure the router
- Open the address 192.168.1.1 in the browser
Enter login - root, password - empty, click the Login button. - Configure access to the router:
- System → Administration menu
- Set a new password
- Configure SSH (fields: Interface = lan, Password authentication = enable, Allow root logins with password = enable)
- Save & Apply Button
- Configure WAN (Internet access):
- Network menu → Interfaces
- WAN Icon → Edit Button
- We configure the connection to the provider (fields: Protocol, etc.)
- Save & Apply Button
- Configuring 3G
- Open the console MSYS2
- Connect to the router via SSH:
ssh root@192.168.1.1 - Enter the password
- Install the packages:
opkg update opkg install comgt kmod-usb2 kmod-usb-ohci kmod-usb-serial kmod-usb-serial-option kmod-usb-serial-ipw kmod-usb-serial-wwan kmod-usb-acm luci-proto-3g usb-modeswitch usb-modeswitch-data usbutilsComment:1. The opkg update command must be re-executed in each SSH session (and possibly before each opkg install). In any case, if the opkg install command does not find a package, you need to run opkg update.
2. It is possible that only one of the kmod-usb-serial-wwan, kmod-usb-acm packages is available (this is indicated on the wiki.openwrt.org/doc/recipes/3gdongle page), but I didn’t really understand both.
3. Usb-modeswitch, usb-modeswitch-data, usbutils packages are kind of not needed - usb-modeswitch * are needed if the modem is defined as a disk (I did not have one), usbutils is needed only to recognize VendorID and ProductID. - Create a script with USB device settings (correct VendorID and ProductID):/etc/hotplug.d/usb/22-3g_dongle
echo '#!/bin/sh idvendor="2020" idproduct="4000" bcddevice="300" if [ "${PRODUCT}" = "${idvendor}/${idproduct}/${bcddevice}" ]; then if [ "${ACTION}" = "add" ]; then echo '${idvendor} ${idproduct} ff' > /sys/bus/usb-serial/drivers/option1/new_id fi fi ' > /etc/hotplug.d/usb/22-3g_dongle
Comment:1. You can copy the command, starting with echo
2. The end of the EOL line should be a UNIX format (LF, not CRLF), that is, copy the command into a text editor (for example, Notepad ++) and replace the line ends, and then copy it to the console.
3. idvendor, idproduct, bcddevice can be viewed with the lsusb -v command (usbutils package), if these values ​​suddenly fail. - Create a script with modem settings:/etc/chatscripts/3g.chat
echo 'ABORT BUSY ABORT VOICE ABORT "NO CARRIER" ABORT "NO DIALTONE" ABORT "NO DIAL TONE" ABORT "NO ANSWER" ABORT "DELAYED" ABORT "ERROR" ABORT "+CGATT: 0" "" AT TIMEOUT 30 OK ATH OK ATE1 OK AT+CFUN=1 OK AT+CGATT? OK AT+CGDCONT=1,"IP","\T" OK ATD*99# TIMEOUT 22 CONNECT "" ' > /etc/chatscripts/3g.chat
Comment:1. The end of the EOL line must be UNIX format.
2. The file name /etc/chatscripts/3g.chat can be different: run the command ls -n / etc / chatscripts / and see which files are created after setting up the 3G connection (via the web interface or console) - Reboot the router: reboot command in the console or via the web interface
- Go to 192.168.1.1
- Add a new network interface for a 3G modem:
- Network menu → Interfaces
- Add new interface button
- Open the General setup tab, fill in the fields: Name = WAN3G, Protocol = UMTS / GPRS / EV-DO
- Submit button
- Fill in the fields: Modem device = / dev / ttyUSB0, Service type = UMTS / GPRS, APN = internet.rt.ru, username = ncc, password = ncc
- Open the tab Firewall settings, set the switch Assign firewall-zone = wan
- Save & Apply Button
- Turn off the power of the router, unplug the WAN cable of the ISP.
- Turn on the power, after downloading the router, the modem should work and the Internet should appear.
If not earned
1. Watch logs - Kernel Log
Via web-interface: Status menu → Kernel Log
Via console (ssh):
dmesg | grep usb There should be entries like this:

Keywords - usbserial , ttyUSB * .
If they are not there, then make sure that all packages are delivered: System → Software menu or a command in the console.
opkg list-installed Make sure that in /etc/hotplug.d/usb/22-3g_dongle the idvendor , idproduct , bcddevice parameters match the USB device. This can be viewed in the console with the command
lsusb -v | grep -e idVendor -e idProduct -e bcdDevice. Something should be displayed.
idVendor 0x2020 idProduct 0x4000 bcdDevice 3.00 idVendor 0x1d6b Linux Foundation idProduct 0x0002 2.0 root hub bcdDevice 3.10 idVendor 0x1d6b Linux Foundation idProduct 0x0001 1.1 root hub bcdDevice 3.10
