• 1300 Mbps - 3SS 5GHz 802.11ac (80MHz chan.),

• 450 Mbps - 3SS 2.4GHz 802.11n (40MHz chan.) = AC1750 class

Overview

AVM supply has 3 different OEM firmware versions for the 7490. At this time, it is known that Germany use AnnexB, while international use AnnexA so at a minimum, there must be at least 2 hardware versions, but with the 3rd firmware image for Belgium there might even be 3 different hardware versions of this device. The bulk of the documentation below is based on the International version of the 7490 (which also had markings for AU/NZ included in few places).

1. Check which NAND the device has by using the following procedure with stock firmware:
2. Go to to http://192.168.178.1/support.lua download the support data file and search for string "NAND device" to get the manufacturer kernel output.
3. Use Micron image if Micron is displayed otherwise the non-Micron image.
4. Use the eva_ramboot.py script to boot the initramfs image. Follow the procedure to interrupt booting by ftp into 192.168.178.1 within 5 seconds after poweron.
5. Then transfer the sysupgrade image to the device and run sysupgrade to flash it to the NAND.
6. For making USB work, an renesas xhci firmware file (e.g. v2026) is needed and it should be copied to /lib/firmware/ (file name renesas_usb_fw.mem).
