Welcome. hMailServer is a free, open source, e-mail server for Microsoft Windows. It's used by Internet service providers, companies, governments, schools and enthusiasts in all parts of the world. It supports the common e-mail protocols (IMAP, SMTP and POP3) and can easily be integrated with many existing web mail systems.
PLEASE HELP!!!!!!!!! If you have a modem with a built in router, you can use it as a wireless (wifi) router. Wifi doesn't cost money as a service. You just need the devices that are compatible with it. Wifi is just a different way of connecting stuff to the internet.
Your router has very little impact on speed of the internet. The only thing would be if your ISP offers ADSL2 and you router only supports standard ADSL. the speed of the WIFI will have no impact on download speed from the internet. as wifi at it's current slowest being 54mbit and your internet is at 10mbit.
