Overview
DWM-222 is 4G/LTE USB modem by D-Link. This article contain configuration details and test results. USB modem was tested connected to Mikrotik RB951G-2HnD with RouterOS version v6.40.1 (stable).
Modem capabilities
- Broadband Wireless Support:
- LTE/DC-HSPA+/HSPA/WCDMA
- GSM/GPRS/EDGE
- Radio Frequency Bands:
- LTE @ 2600/1800/800 MHz
- UMTS @ 2100/900 MHh
- Quadband GSM/GPRS/EDGE
- Data Rate:
- LTE: 3GPP Rel-9 FDD-LTE Cat.4
- Downlink: Up to 150 Mbps
- Uplink: Up to 50 Mbps
- DC-HSPA+
- Downlink: Up to 42 Mbps
- Uplink: Up to 5.76 Mbps
- LTE: 3GPP Rel-9 FDD-LTE Cat.4
Visual indication (Status LED)
- Red (blinking): No SIM Card / No Service (or searching for service) / General Error condition
- Purple (blinking): Connected to 2G (GPRS/EDGE) network
- Blue (blinking): Connected to 3G (UTMS/HSPA/HSPA+)network
- Green (blinking): Connected to 4G (LTE) network
Note: Apparently keep alive of modem is indicated by blinking of status LED. When this status LED turn solid then it was most of the time host disconnect or firmware error/crash. Color remain as "last used" and did not switch to red. You can get modem out of this state for example by power cycling power -> /system routerboard usb power-reset duration=10s
Configuration
General configuration
This configuration is optional but I recommend to set port name. This will make configuration easier to read.
- Switch to port menu and list connected devices. Identify device by id or just by comparing output before and after connecting USB modem:
> /port print
- Set name on identified port (replace "0" with actual port number):
> /port set 0 name=Orange
- List configured ppp client interfaces:
> /interface ppp-client print
- Remove auto-configured interface (adjust name / number if necessary):
/interface ppp-client remove ppp-out1
- Add new ppp client interface:
/interface ppp-client add dial-on-demand=no disabled=no apn=internet data-channel=1 info-channel=2 name=ppp-wan port=Orange
Note1: You may add use-peer-dns=no
and modem-init="<AT command>"
depending on configuration.
Note2: APN depend on internet provided (cell operator).
Note3: This modem is enabled by default. Option modem-init="AT+CFUN=1"
is not necessary.
Native LTE
Modem is not detected as native LTE modem in RouterOS. I am not sure if this is limitation of modem itself or missing support in Mikrotik RouterOS image. Serial "PPP" interface is working fine.
