Without a minimum knowledge of networks, setting it up will be very problematic. Approximate settings suitable for most and explanations for them on the Internet are more than enough. But if you want to solve a non-standard problem - don't count on free help and advice in RuNet :) Yes, and with a paid one, it's not very good either . I bought Cisco 857W instead. I don't regret buying :)
