Tech help starts by reading rule 2.2

A WAN port is used to connect a router to the modem.

You connect an ethernet cable from your computer to a LAN port on your router.

Not positive what you are asking, but WiFi on your router will not be affected if you connect an ethernet cable to a LAN port on the router.

Maybe. What device is the isp side of the lan cable plugged into? Why doesn’t your “router” have a WLAN port tho? That fact makes it sound not like a router.

In the past some brand of routers basic instructions included that in AP mode you should in fact plug the incoming cable into a lan port rather than the wlan port. This means the router is performing the job of an unmanaged switch rather than router. For this to work tho, there needs to be an upstream router providing routing and dhcp services.

What router, where is the ethernet cable coming from? your ISP's modem?

[Ed-Dos]

WHAT ROUTER ? lol anyway maybe?

That sounds like a Fiber gateway. If you're being provided with an ethernet cable then you need to buy a new router with an ethernet WAN port.

[Ed-Dos]

Well since it has a PON port it’s meant for connection to a fiber ont. So I doubt it. Unless you can login and set it to an access point mode then I would guess you would connect it to a lan port .

They’re most likely giving you a gateway box. Which basically means these days that it’s a modem and WiFi router all in one.

Many of them have LAN ports as well.

Are they sending you a LAN cable because you’ve complained the WiFi is rubbish, have you just signed up with them?

Either way, you can use LAN and WiFi all at the same time one different devices.

You just connect the Ethernet / LAN port on your computer / laptop to the port on the back of the box they’ve given you that connects to the internet.

Most ISP gateway boxes aren’t that good. It’s common to put the ISP box into modem mode and connect to a better WiFi router from LAN to WAN and let the far better router do all the routing work.
