Connect AP via wifi to another AP?

[krampak]

Let's see if someone can enlighten me... I need to put a computer/printer/labeler in a production line that is not wired and for the moment, if possible, I would like to connect these 3 devices by cable to a wifi access point and for this to connect via wifi to another access point that is on the ceiling that is connected to the company's local network.
Does anyone know if this is possible and what type of access point / configuration I need to use? I have been reading a little and it seems that I have to configure the remote access point (the one that does not have cable access to the local network) in bridge mode and put the other access point's address as the destination address, but my doubt is how the link is made... what channel to use (the same for both?), how the remote is authenticated with the local one and if "any" AP is enough or do I have to go for something specific.

PD: Can someone clarify the difference between the concepts "Client Bridged mode","Ad-Hoc mode" and "WDS-LAN"? XD

Well, the times I've done it, I've put the access point in client mode. Once in that mode, a list of nodes it listens to should appear, and that's when you choose where you want to connect (just like on a PC).

I suppose it depends on the model, but in mine (a DLink) you don't have to worry about choosing channels or stories; it connects as just another client and that's it.

So the only AP that needs to be configured differently is the one on the "remote" side, so to speak? I have a Dlink with DD-WRT here next to it, and in the help it says:

AP mode – This is the default mode, also called Infrastructure mode. Your router acts as a central connection point, which wireless clients can connect to.

Client mode – The radio interface is used to connect the internet-facing side of the router (i.e., the WAN) as a client to a remote accesspoint. NAT or routing are performed between WAN and LAN, like in "normal" gateway or router mode. Use this mode, e.g., if your internet connection is provided by a remote accesspoint, and you want to connect a subnet of your own to it.

Client Bridged mode – The radio interface is used to connect the LAN side of the router to a remote accesspoint. The LAN and the remote AP will be in the same subnet (This is called a "bridge" between two network segments). The WAN side of the router is unused and can be disabled. Use this mode, e.g., to make the router act as a "WLAN adapter" for a device connected to one of its LAN ethernet ports.

Ad-Hoc mode – This is for peer to peer wireless connections. Clients running in Ad-Hoc mode can connect to each other as required without involving central access points.

According to you, would it be the second mode? I was more inclined to go with the third one XD Let's see if I can find another AP to test it in the office first...

Edit: Well, I've talked to the technician from our provider and the access points we usually set up (Motorola) can be configured in "base bridge mode" and "client bridge mode" and make a "mesh network" for the purpose I was looking for, so in principle that will work...

[cobito]

Yes, I meant the second mode. In this way, the ethernet port of the "client" PA is like an additional port of a hypothetical switch in your wired network.

By the description it should be the third mode, client bridged mode
