CAN devices on different SSIDs communicate?

No, just having different SSIDs as per your diagram would put Computer B on the same network as your other machines. It would be able to communicate with everything else on your network. The SSID is just used as an identifier for the wireless connection your adapter will connect to.

What happens when two SSIDs are the same?

Two identically named SSIDs with the same password will allow your device to connect to either, without having to add any extra networks on your devices. If both routers are broadcasting from the same location, the expected behaviour will vary depending on device.

What are the benefits of having multiple SSIDs on the same router?

An important benefit of multiple SSID routers is that you can have password-protected internal and a public guest network. It allows internet access with no internal access. That way, you will end up with a degree of isolation, especially when you set up the router in an environment with many users.

Are different SSIDs different networks?

The Service Set Identifier (SSID) defines what is thought of as the wireless network. So you can mistakenly think of those two SSIDs being associated with different physical networks. In addition to multiple access points broadcasting or using the same SSID, a single access point can also use multiple SSIDs.

Should you name both SSIDs the same?

Pros of naming the SSIDs the same: Almost all current wireless devices support both 2.4Ghz and 5Ghz frequencies. Older 2.4Ghz only devices will just connect to the 2.4Ghz frequency and not even see the 5Ghz frequency, so having the same SSID will work fine for them.

Can one modem have two networks?

Yes, it is possible to use two (or even more than two) routers on the same home network. The benefits of a two-router network include: Support for more wired devices: If the first router is the wired Ethernet kind, it supports a limited number of connected devices (typically only four or five).

How many SSIDs is too many?

What does “too many” mean? Well, having more than one SSID isn’t bad as they can be used to provide different levels of wireless access to different users and devices, but, to reduce overhead, it would be best to deploy no more than 3 SSIDs.

Should you split 2.4 and 5GHz?

Separating the bands of the router may help you to maximise the WiFi speeds around your home. 2.4Ghz (gigahertz) can cover a further distance from the router, however the connection speeds are slightly slower. 5Ghz covers a shorter distance from the router, but the speeds are faster.

Should 2.4 and 5GHz have same name?

Almost all current wireless devices support both 2.4Ghz and 5Ghz frequencies. Older 2.4Ghz only devices will just connect to the 2.4Ghz frequency and not even see the 5Ghz frequency, so having the same SSID will work fine for them.

Can you have 2 different internet providers in the same house?

You can have as many providers as are willing and able to connect service to you, be that via cable, wireless, satellite, fiber, or carrier pigeons. Your router will need to be able to decide which connection to use for a given connection inside your network.

How do I connect two networks to one Internet connection?

You should be able to use normal UTP cables to connect the routers together. Connect any normal LAN port (don’t use an “Uplink” port) on the “Internet” router to the WAN port of each of the two other routers. Illuminated Link lights at both ends of the connection should tell you when you’ve successfully connected.
