the download is cut off when the router needs the password

Hi
my provider is using mikrotik server and while im downloading a file using any accelerator and after a time the download is stoped and it needs to open the browser and login !!!

can i do any thing from my computer to automate this?
if not can the ask the provider to do something?

thanks in advance.

tell the provider to increase the timeout for users, so the server doesn’t log off the customers so soon.
