well the fast way is to kill the download and download again then it trys to connect right away...
anyway I belive the time waiting for a requery gets higher by each interrotation. the first time its like 200 sec after those its like 600 and it gets higher.... each time.
personally i don't like the requery send thing at all. I don't really even know what it's for. I just guess it's some like push....
i don't think you can set it manually anywhere.
