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.
Since a router typically has more Wi-Fi power than a client in a particular wireless connection, the router is hardly used at full capacity. For example, a three-stream 802.11ac router, such as the Linksys WRT1900AC, has a max Wi-Fi rate of 1,300 Mbps, but the iPhone 6s has a max Wi-Fi rate of just 833 Mbps (dual-stream).
