Everyone who keeps saying reset router, use admin/pass: x you can't read or deduce anything by yourselves. You have to be a downy not to setup a router with a better password than blank or admin nowadays. He's stated he's unable to get into the room with the router so that isn't going to work, and even if he could it won't change much as his brother will just set the router back up (I've deduced this...)
Swiftkit, runescape.com, any botclient, or RS client will not work for him. I believe his brother has blocked all sites that relate to runescape.
I'm not sure there is anything you can do other than continue trying things like ultrasurf/buy a new router.
PS: Don't call your goddamn ISP this has nothing to do with them. The person that commented that is so technologically inept I'm surprised they managed to find sythe.org...
