Hi all - I have a small office network ... 1 room, 2 computers (Macs), 2 printers, and an IPhone.<br />
All connected via Fiber Modem (Arris NVG595) &amp;&nbsp;separate WiFi router (ASUS TM-AC-1900).<br />
For the past several months, I have been pulling my hair out, with printers &quot;sometimes&quot; seen my the Mac, Airplay printer &quot;sometimes&quot; being seen by the iPhone, etc. <br />
Fortunately, I have the issue narrowed down to this (assuming this is the cause):<br />
When one of my Macs/Ptrs is connected to the LAN via Ethernet, it uses the internal IP of 192.168.7.xxx<br />
When one of my Macs/Ptrs is connected to the LAN via Wireless, it uses the internal IP of 192.168.29.xxx<br />
(FWIW I only use band 2.4GHz. I have nothing using band 5.0 GHz).<br />
Can anyone direct me from here? Do I need to have everything on the same subnet?

IP SubNet madness! Help ...

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Apple devices including Macs, iPhones, iPods and iPad support standard wired and wireless networking technologies, but they also utilize custom applications and some special techniques for networking with each other and with non-Apple devices. Apple manufacturers the AirPort line of wireless networking products, and has its own networking protocols, AppleTalk and AFP (Apple Filing Protocol).
