hello ahishbhigesara
Were you able to find a solution for this ?
I am looking for same combination
Did you install OpenWrt on TL-MR3220? According to specs it has USB port. 4MB flash is not much but should do. I assume that DWP-157 uses RAS so it might work.
yes so I did install OpenWrt but there is nothing on interface to configure so just wondering if need to do something extra for this to work
Try this steps:
1. Plug modem to USB port.
2 .Connect to router using SSH.
3. Execute following commands to install packages.
# opkg update
# opkg install kmod-usb-core kmod-usb2 usb-modeswitch libusb-1.0
# opkg install chat comgt kmod-usb-serial kmod-usb-serial-optionCheck modem if LED started blinking.
4. Write commands to configure 3G connection.
You have to set your APN, user name, password and SIM card PIN number. If there is no PIN/uname/password, just omit this lines. Wrong PIN may lock card!
# uci del network.wan
# uci set network.wan=interface
# uci set network.wan.proto=3g
# uci set network.wan.device=/dev/ttyUSB0
# uci set network.wan.pincode=1234
# uci set network.wan.apn=apn_name
# uci set network.wan.username=user_name
# uci set network.wan.password=password
# uci commit network
# rebootAfter reboot router should establish connection.
lukasgl's instruction worked for me. You should try it.
Thank you, lukasgl
Hi lukasgl,
I am using combination of TP-LINK router(Model: TL-MR3020) with OpenWrt firmware (Firmware Version: Barrier Breaker 14.07) and D-Link 3G usb modem (Model: DWP-157) to access internet via the WiFi created by router.
I followed all the steps mentioned in your post but when I plug the usb modem in the router, the router is unable to mount it (that means no /dev/ttyUSB is created ).
Following are the dmesg logs when D-Link dongle is connected:
root@OpenWrt:~# dmesg
