I have a Telekom Malaysia standard-issue Riger DB-108WL wireless modem/router. Yes, I know it's a really crappy piece of hardware. Actually, it's about the crappiest router I've ever used, and I've used bad ones. But I did get automatic reconnection working with jDownloader.
It's actually pretty simple, all it needs is the router's IP and login, and the following code block in "Settings > Modules > Reconnection", in the "LiveHeader/Curl" tab.
1 [[[HSRC]]] 2 3 [[[STEP]]] 4 [[[REQUEST]]] 5 GET /rebootinfo.cgi HTTP/1.1 6 Host: %%%routerip%%% 7 Authorization: Basic %%%basicauth%%% 8 [[[/REQUEST]]] 9 [[[/STEP]]] 10 11 [[[/HSRC]]]
For me, it takes between 90 and 120 seconds to reconnect. During the day, I find that very annoying, so I don't do autoreconnect, but if I leave the computer running over night, I usually turn it on.
