wAP R ac with Quectel EP06 fudge as Phone

How to make your wAP r AC with Quectel EP06 appear as a phone to your telecommunications service provider.

1. Install the EP06 Mini PCIe modem in a mini-PCIe LTE modem to USB-A dongle
2. Connect it to a PC/laptop/SBC with a serial terminal emulator
3. Set EP06 to USB 2.0 mode: AT+QUSBCFG="SS",0
4. Set EP06 to MBIM mode: AT+QCFG="usbnet",2

• If you don't have/can't buy a suitable adapter, taping off the USB 3.0 pins also works

1. Install RouterOS (ARM) version ≥7
   • Main package routeros-7.x.y-arm.npk
   • Extra packages → wifi-qcom-ac-7.x.y-arm.npk (WifiWave2)
     
   • If installing WifiWave2 fails due to a full disk, install Extra Packages → wireless-7.x.y-arm.npk instead (WifiWave1) or install the packages with Netinstall
2. Reset configuration

1. Log in to wAP R ac with Winbox
2. Fudge IMEI (avoid MiFi router modem detection)
   1. /interface lte settings set mode=serial
   2. /system reboot
   3. (Wait for reboot)
   4. /system/serial-terminal usb1 channel=2
   5. AT +EGMR=1,7 "REPLACE_WITH_NEW_IMEI" (the double quotation marks " are required)
   6. Ctrl-a + q to exit the terminal
   7. /interface/lte/settings/set mode=auto
   8. /system reboot
   9. (Wait for reboot)
3. Fudge TTL (avoid tethering detection)
   • IPv4
     1. /ip firewall mangle add chain=postrouting out-interface=lte1 action=change-ttl new-ttl=set:64 passthrough=yes
   • IPv6
     1. Enable IPv6: /interface lte apn set [ find ] ip-type=ipv4-ipv6 ipv6-interface=bridge
     2. /ipv6 firewall mangle add chain=postrouting out-interface=lte1 action=change-hop-limit new-hop-limit=set:64 passthrough=yes protocol=!icmpv6
     3. /ipv6 firewall nat add chain=srcnat out-interface=lte1 action=masquerade
        (optional, depends on how strict your operator is - did not require this for DiGi; will break globally routable public IPv6 for end devices)
4. Now use Quick Set to finish the remaining configuration for your APN (if LTE is not working) and Wi-Fi
