Is it possible to have both Wireless and a wired connection at a house?

yes

Hi yes both types of network connectivity are available how ever in some circumstances wifi does not work. one cause is the fabric of the building. concrete and steel have to be one of the worst. along with blue lier stone work as the stone contains lead.

The speed isn't going to be any faster through a cable it will just be more reliable. If you didn't know, the wifi icon only indicates the signal strength it does not indicate speed. Wired or WiFi you are getting the same speed. The thing with Wi-Fi is if the signal gets weak enough it could drop off and that is where the speed can get slower. It actually doesn't get slower it just disconnects completely if the signal drops to nothing (no bars). Wi-Fi is also subject to interference which can cause low signal strength. An aluminum wall or window shade or siding on a house kills a Wi-Fi connection because the radio signal cannot go through aluminum.

Yes, it is possible to have both Wi-Fi and wired. It's not possible to double the speed by connecting both WiFi and wired to the same device. It doesn't work that way, you either get Wi-Fi or you're wired. Not both.

The only way to increase the speed you get is to upgrade your package to a faster speed with your internet service provider.

Yes, nowadays home routers are like that since the very beginning, two subnets back then but now unified into a single sub, I think you are missing the question of Ethernet over Powerline. But that s also easy, they are nothing more than a piggyback extension.

I believe so, yes. Most modern home routers I think still have Ethernet ports on them - either in the front or the back. Just plug an Ethernet cable into one of those ports and you can still have wireless at the same time. It's possible you may see a decrease in speed performance between the two types of connections, but it should be rather minimal I think.

Yes. Chinitos will set it up.

Of course on the back of the router you'll see plugs to plug an ethernet cord into the ethernet port of your device and at the same time you can still leave the wireless turned on for everybody else

Most home wireless routers support up to four Ethernet connected devices as well as WiFi connected devices. They can all be used at the same time.

WiFi forms a single interface that can pass only one packet at a time between devices and the router. A data packet goes over the WiFi network to one of your devices, then perhaps another packet may be sent to another device, or a device might send a packet to the router. Sometimes devices or the router might start to transmit on the WiFi network at the same instant as another device starts to transmit. This is called a collision, and means that both packets are lost. In addition, the WiFi network cannot be used until the colliding packet transmissions have ended.

Each Ethernet port on the router is a dedicated connection and packets can travel both ways simultaneously. Collisions do not occur.

This means that Ethernet is normally a far better choice for online gaming than a WiFi connection. Where possible use Ethernet for games consoles, desktop PCs, TVs etc, and keep WiFi for portable devices and those that do not have Ethernet capability.

I hope this helps.

Of course it is. I have both on a computer.

Yes, just wire your PS4 into the router using an Ethernet cable. Unlikely to make your connection much faster though.
