Background
We have a flat that is (almost) covered quite well by one WIFI router. One of my children now moves to another flat in the same house, that is not covered by our WIFI. I'd now like to extend the WIFI with two or more mesh repeaters, so that our own flat and the new flat is well covered, and we don't need so switch WIFI when we move between the two flats.
Problem
Of course, the easiest thing would be to buy mesh repeaters with from the manufacturer of the existing router. The drawback is
- WIFI repeaters from this manufacturer have quite bad reviews on the internet; WIFI mesh repeaters from other manufacturers seem to have better reviews and are cheaper.
- I'd not like to change the router, as these would be additional hardware costs, and as the current router has a programmable interface (API), and I can centrally switch on and off the network access for individual devices by our (small) smart home solution (eg. block internet for children between midnight and 6 a.m.).
Specifications
Existing router
Nighthawk R7000 Wifi 5 (IEEE® 802.11 b/g/n 2.4GHz, IEEE® 802.11 a/n/ac 5GHz)
Disclaimer: I'm quite satisfied with the router. I only put the manufacturer/model here to make sure enough information is provided for answering the question. I'm not saying that any specific manufacturer or it's products are 'good' or 'not so good'.
Wifi mesh repeaters
Should already support Wifi 6
Question
What do I have to take into account to make sure, that I can combine a router vom manufacturer A and WIFI mesh repeaters from manufacturer B, so that they build up a good working mesh networh? (Thought: Would it help to overwrite the firmware of the existing router with DD-WRT or OpenWrt in order to make this possible?)
Any hint is highly appreciated!
If the question seems inappropriate or improveable, I'd highly appreciate if you leave a comment so that I can improve the question, instead of simply downvoting it, especially if you downvote it without telling me why. Thank you very much in advance!
