amod is a Netgear DGN2200V4 Annex A firmware mod; among others, it includes:
amod is based on the last DGN2200V4 Annex A Netgear official firmware 1.0.108 and it is created using the open source image stuff by Netgear. It means you can modify amod in the same way amod was written modifying the original Netgear firmware.
Note: to set up amod, go to http://router_address:8082
amod is developed by Alfonso Ranieri. The part he wrote is distributed under the terms of the GPL II. The rest of the firmware is copyright by Netgear and it is distributed under its terms.
amod for the DGND4000 is here.
You can find amod for the Netgear DGN3500 here.
The version for the Netgear DGN2200V3 is here.
The ufficial HWUpgrade Forum amod thread is located here (if you don't speak italian, feel free to write in english there).
Now the usual but very important part: amod is distributed without any warranty. Please read twice: you install it in your router at your own risk. It might destroy your hardware, your data and it might suggest your partner to leave you. It is your own choice. Neither Alfonso Ranieri, neither any other part involved may be considered responsible for any damage caused by improper but also proper usage of amod. Understood? Great! You can now download it. Otherwise, bye bye.
