Dual Band (concurrent), Gigabit Ethernet and ADSL Modem. Advertised as 1750 Mbps. It has simultaneous Triple-Stream (3×3) radios on both 2.4GHz and 5 GHz Bands. It supports 802.11n in 2.4GHz for 450Mbps throughput and IEEE 802.11ac (draft) for 1300Mbps throughput in 5GHz.

This modem is practically divided in 2 sections:

• Router section: This part shares the same hardware with Archer C5 v1 and Archer C7 v2
• Modem section: Based on BCM6318 (unsupported)

→ Install OpenWrt (generic explanation)

Please add the installation procedure here.

Configure your favorite terminal with the following settings: 115200 baud, 8 bit, no parity, 1 stop bit, no flow control.

To enter into the bootloader, press “t” when it says: “Hit any key to stop autoboot”

Default user and password for console login inside the original OEM firmware is admin/1234

Since opening the case is relatively hard (because of the hard to remove silver clip and strong plastic clips), the easiest way to gain Serial access is by using some snips to cut out part of the case.

To open the case you have to remove two screws underneath the information sticker and one screw below the silver front clip which should push forward, then you need to pry open the rest of the case which is clipped together (2×3 side clips; 2 front clips; 2 back clips).

Developers are currently working on OpenWrt for this router Here. The following tutorial allows only a complete shell access to the router. When the firmware will be ready for this router, this page will be updated with a proper guide.

This hack is the same used for the w8970/w9980 https://forum.kitz.co.uk/index.php?topic=17108.105.

You'll need python3 and pycrypto to run this script. You can install pycrypto by:

• apt install python3-crypto
• OR pip install pycrypto
• OR pip install pycryptodome

Download this python script: https://github.com/sta-c0000/tpconf_bin_xml/blob/master/tpconf_bin_xml.py

1. Download the system configuration from the OEM interface (System Tools → Backup & Restore → Backup)
2. Rename it in “config.bin” (if necessary) and copy it in the same folder of the tpconf_bin_xml.py script.
3. Execute

   python3 tpconf_bin_xml.py -n conf.bin conf.xml

4. Open the conf.xml file with a text editor and add the following line inside the “<DeviceInfo>” tag:

   <Description val="Modem Router`telnetd -p 1023 -l login`" />

   1. Before

      <?xml version="1.0"?>
      <DslCpeConfig>
        <InternetGatewayDevice>
          <DeviceSummary val="InternetGatewayDevice:1.1[](Baseline:1, EthernetLAN:1)" />
          <LANDeviceNumberOfEntries val=1 />
          <DeviceInfo>
            <ManufacturerOUI val=XXXXXX />
            <SerialNumber val=XXXXXXXXXXXXX />
            <HardwareVersion val="Archer D7 v1 00000002" />
            <SoftwareVersion val="1.6.0 0.9.1 v002d.0 Build 160216 Rel.57110n" />
            <UpTime val=4 />
            <X_TP_IsFD val=3 />
          </DeviceInfo>
          ...

   2. After

      <?xml version="1.0"?>
      <DslCpeConfig>
        <InternetGatewayDevice>
          <DeviceSummary val="InternetGatewayDevice:1.1[](Baseline:1, EthernetLAN:1)" />
          <LANDeviceNumberOfEntries val=1 />
          <DeviceInfo>
            <ManufacturerOUI val=XXXXXX />
            <SerialNumber val=XXXXXXXXXXXXX />
            <HardwareVersion val="Archer D7 v1 00000002" />
            <SoftwareVersion val="1.6.0 0.9.1 v002d.0 Build 160216 Rel.57110n" />
            <UpTime val=4 />
            <X_TP_IsFD val=3 />
            <Description val="Modem Router`telnetd -p 1023 -l login`" />
          </DeviceInfo>
          ....

5. After editing the conf.xml file it must be coverted back the configuration file using the previous python script:

   python3 tpconf_bin_xml.py conf.xml conf_new.bin

6. Restore the modem's configuration using this new conf_new.bin file. (System Tools → Backup & Restore → Restore)
7. Now you are able to connect to the router using telnet on port 1023:

   telnet 192.168.1.1 1023
