A soft reboot may not work, do a full shutdown.

If you see 'NETWORK_REGISTRATION_FAILED', power off the router, wait a couple of seconds and power it back on. If you see a valid IPv4 address, like on the screenshot, it means that your connection has been established successfully, and the last thing to do is to configure the 4G interface as a default WAN. If your carrier supports IPv6, you can use that as well (not recommended). This is based on the 'PDP Type' selected in the previous step. The '_4' means that the interface has an IPv4 IP address. One called '4G' and another one 'Virtual dynamic interface (DHCP client)' called '4G_4'. Please note that two interfaces showed up. If your SIM card has a PIN number, make sure to enter that.Īfter a minute, your interfaces should look like on the screenshot below. Input the other fields as you see on the screenshot. If you don't see this device in the dropdown, your modem is not detected. Select '/dev/cdc-wdm0' in the 'Modem device' dropdown. If you don't know what to input here, google for 'APN + your provider name'. Step 3: APN configurationĪPN stands for Access Point Name and it's the name your modem will try to connect to gain access to the public internet. The important configuration fields here are 'APN' and 'Modem device'. This is the main configuration screen for your LTE connection. If you don't see QMI on the list, you have not installed the right packages or haven't rebooted the router.Ĭlick 'create interface' to go to the next step. In this example, I named my interface '4G'. Go to Network => Interfaces => click 'Add new interface' If you don't reboot, the next step won't work.

Go to Software -> Update list -> search for QMI -> install the following packages. This protocol is well supported in OpenWRT and is able to deliver a good performance. In this article, we are using the Quectel modem so we will use the QMI protocol. Each one is configured slightly differently and has a different level of support in OpenWRT. There are PPP, QMI, MBIM, NCM and a few others.

There are many different proprietary cellular communication protocols and it may be a little overwhelming to know which ones work well, which ones your modem supports and how to get the modem working properly. Category 4 modems can get a theoretical maximum of 150Mbps download speed and 50Mbps upload speed. Please note that these speeds are theoretical, and in practice, the speed of 100Mbit/s is often maximum achievable. The actual speed depends on a variety of factors such as distance to the nearest base station, capabilities of the base station, antennas used, time of day or even weather conditions. The popular mobile modems available on the market are Category 4.

Please refer to the image below for details. In that case, you should connect the SIM card to SIM2 slot. If your operating system is installed on an SD card or USB thumb drive, you can also use the first mPCIe slot that is usually occupied by the mSATA SSD drive.

If you are also using PC Engines APU3 or APU4, please make sure to connect the SIM card to SIM1 slot, and your modem to the middle mPCIe slot. This hardware combination works very well in our experience. In this tutorial, we are using Quectel EC25-E LTE modem with APU4D4 motherboard. Some modems aren't compatible with some motherboards. There are many 3G, 4G and LTE modems on the market, but not all of them work well with OpenWRT. The first thing you need to do it to have compatible hardware. If that's not the case, please start by installing OpenWRT on your router. Please note this article assumes that you have OpenWRT already installed. This step by step tutorial will show you how to configure a 4G mPCIe cellular modem, and use it as the main internet connection in OpenWRT.
