Which WLAN repeater is most useful for which base station?

We have a Fritz Box 7390 as a base station. A specialist dealer in the vicinity equipped several Devolo repeaters several years ago. Everything works fine.

Would it make sense to replace these Devolo repeaters with repeaters from Fritz? Since repeater & base station are of the same brand, I could imagine that they would "work together" better. Are there any details that you have to be careful about? I would like to organize my network clearly. Unfortunately, I don't know my way around the way the specialist dealer has set it up.

Are there various products that make sense? E.g. I need a repeater for the lower living room, which only emits Wi-Fi. In the upper living room there are also PC & PS5, which I would like to connect with LAN. There may be different products here that are helpful or better suited for a wide variety of situations.

The repeater company is mostly just easier for installation if it's the same.

The upper devices can be connected with cable ducts downwards.

Network components from different manufacturers work equally well with one another. However, some manufacturers have extra functions that only work with products from the same manufacturer. There are also repeaters that have network connections.

Since your old Fritzbox doesn't support mesh anyway, you can save yourself having to switch to AVM for the repeaters.

First of all I would like to know whether the repeater are repeater at all, or maybe powerline adapter.

and then it is the case that the manufacturer plays a subordinate role here. There are standards that every manufacturer SHOULD adhere to. Devolo and AVM (the manufacturer of the Fritz box) adhere to these standards. So an exchange with repater from AVM (if the old ones were really repater) will not have any significant effect. The advantage of products from one manufacturer is often only that it is easier to manage.

by the way, avm also offers powerline solutions.

the only question is whether so many repeaters make sense at all or do not even interfere with each other.

it's like equipping your car with 5 spoilers and killer-width tires in the hope of making it faster.

Just looked up. The Devolo are powerline adapters. Is that different from a repeater? I don't need a lot of repeaters if you can hear that.

I need (in the best case)

2x repeaters for the ground floor (1x for the business and 1x for the living room)

1x repeater for the upper floor (in my room, since PC & PS5)

The Fritzbox is in the basement. Mesh was discontinued by the specialist dealer through the Devolo adapter.

The specialist dealer has programmed a mesh in us thanks to the Devolo adapter. If you switch to the Fritz Box adapter, can you then no longer adjust the mesh?

If the base station does not support mesh, everything else is very pointless.

You know what?

The 7390 are now so cheap (about 20 euro) that you can use them as an inexpensive repeater. Every Fritzbox can be used as a repeater if it is configured accordingly.

Or you can get a 7590 as a router and use your 7390 as a repeater.

A cheap upgrade!

Is the 7590 the current model?

I also need a LAN connection between the 7590 and 7390 right?

Is it easy to set up the new Fritz Box or do I have to activate it with my provider first?

Yes, 7590 is up to date (avm.de)

No. Lan connection not necessary. WLAN is extended via WLAN you have to find a good place for the 7390 roughly in the middle between the 7590 and your devices.

Setting up the 7590 is at least as easy as setting up the 7390.

You only have to enter the access data, you can take over almost everything from the 7390, including the settings (print out if necessary).

Then the 7390 has to be reconfigured so a new IP address, switch off DHCP, because the 7590 assigns the IP addresses and configure Wi-Fi as a repeater. Finished

If the Fritz box is in the basement, and your fuse box too, I recommend the AV1200 Dinrail from devolo as the "main adapter" that distributes the dlan signal to all 3 phases.

the difference to the repeater is that the repater receives a wlan signal, which it passes on, while the dlan adapter works via the storm cable.
