DGTeam firmware for Netgear DG834Gv4

I have been searching for Wake-on-LAN solution for months for my Netgear router as I like to shutdown my HTPC and wake it over the internet, but none has been working. Until recently I found out DGTeam has released an updated firmware for DG834XX series early this month, and was eagerly waiting for DG834G turn. Finally after days of browsing, I noticed it is out now.

As I'm using Sky's converted Netgear router and it is DG834v3 equivalent, this means either I try to upgrade the firmware and perform recovery if it failed or buy an used DG834v4 from eBay.
