I have a wi-fi network running off of an unlocked 2Wire 2701HG-x modem (user guide). Question: How can I publicly share it? Can I create two separate networks, one for myself (password-protected), and one unsecured (public, with limited bandwidth and/or speed) for all to use? Where do I start? Can I install special software on the router? Purchase special hardware?
Any pointers are highly appreciated. Thank you.
