Is it better to run repeater in 5G and router in 2.4G?

[sytom]

I want to have an AP in my kitchen connecting to main router (in living room) by powerline. Main router is in 2.4G mode. I read that if AP runs in 2.4G too it will interfere with main router, right? So is it better to run it in 5G mode only in my kitchen?

An AP running in 2.4Ghz won't interfere with the main router if you put them on unique channels (1,6,11). A repeater running only in 2.4Ghz has to use part of the time to receive/transmit to the base and part of the time to receive/transmit to the clients. That effectively halves the available bandwidth.
To run the repeater in 5Ghz your main router would also have to be dual band. The 5Ghz refers to the link the repeater makes to the main router. 5Ghz signal does not penetrate walls as well as 2.4Ghz. If you have poor coverage with 2.4Ghz in the kitchen, then the 5Ghz signal strength would probably be even less. You should look into powerline network adapters to create a wired connection to an access point for better 2.4Ghz coverage.

I do plan to use powerline to connect router and repeater, or say extender. When I say 5G I mean between extender and my device.

That wasn't clear from your first post. If your devices support 5Ghz (most older devices don't). and you are near an AP then 5Ghz is a good option. If you are in a "crowded" WIFI environment like an apartment building 5Ghz is a good idea. For single family residential, where coverage is usually more important than total bandwidth, 2.4Ghz provides better coverage and sufficient bandwidth for most people. A fixed device, like an Apple TV or something, which is near an AP could benefit from the extra bandwidth that 5Ghz provides. Handhelds would be better at 2.4.

It would be so nice if the marketing guys hadn't confused everyone. What you are proposing is more correctly called a AP not a repeater. Manufactures would likely call a 100ft ethernet cable a "wired extender" if they thought they could get away with it. Even the term repeater has been abused since there a couple of different types....the ones everyone buys in the consumer stores are the worst kind but they are cheap.

So yes you can "extend" your network using the method you propose and it will work very well compared to using a wireless repeater. You can run just 5g on the device if you choose. Generally if you were getting good signal levels on 2.4g you would no even bother doing what you are doing. So you likely can safely run 2.4g on both devices and not get much interference because the interfering signals will be weak. You would still run them on different channels just because it is good design. I would try both with the 2.4g on and off and see which works best for you.

Thanks for clarification.
