ok... to answer a couple of questions in order:
>> Can't i integrate it as a wetting or will i always have to keep my computer running for a software to stimulate the resync?
You'd always need your PC running. I think the lack of response about a suitable program is that I dont think such a thing exists. I would suggest a scheduled task that runs a telnet script, that I could knock up for you if I get chance.
>> And what is PPP reconnect on the DMT tool?
PPP isn't used on O2/Be broadband... but on most ISP's that require a username and password, it would be used to disconnect and reconnect from the ISP, WITHOUT causing a resync to the exchange. So that wouldn't help you anyway.
>> Isn't there a way to get the router to not resync?
Nope, not for ANY router I'm afraid. If the SNR goes too low, the router will resync. It's annoying, but that's how it is I'm afraid.
