Swak sa budget mo ang Deco M4 na bundle of 3. Been using this mesh since 2019 (from PLDT plan) and hindi pa rin sira haha. Though may deduction talaga sa speed, konti lang naman. Pero it still depends on how far your mesh's are. I recommend buying cat6 to connect each mesh if gusto mo walang speed reduction. Been biased with TP-Link as my smarthome devices na ever since. Lahat ng cctv, smart lights, mesh, and other smart devices ko, TP-Link. Pulido talaga sila, kumbaga.
TP Link Deco M4 works for me, I use 4 in an old large house with thick walls. £160 Amazon.
currently using 2 x be550 with easy mesh --> solid no problem used to have 2 x deco m4 with deco mesh --> solid no problem
yep. i made that mistake too. archer uses "easy mesh" where deco uses "deco mesh" and they dont talk to each other. so if you choose to go with easy mesh (tplink say it is the new standart) go for a easy mesh compatible satellite or if you like deco get another one. it is your choice both are great. (used to have 2 decos for over 3 years now i got 2 x archer be9300 for easy mesh)
I quite like the base model Deco sets and they do fine for lower/moderate speed setups. The M4 is dead cheap or the x something-or-othet is only about £180. Plus they're happy to be wired or mesh! When I say I like, I've installed them for a good few clients as a siple solution to good feedback and no issues to be honest!
E4, M4 and S7 are pretty much the same, they are different generation models with new ones being slim and shorter than the old ones. These 3 are the basic ones and should be more than enough. X series gives you extra security feature (most of them require their paid monthly plan) and x50 that I use allows you to plugin your vpn config and supports wifi 6. If you don't use vpn you are better off grabbing M4 or S7 whichever is cheaper. For my upstairs where I usually work from I have M4.
I've used TP link Deco M4 mesh (5 units) for about 6 years now. It's just a basic mesh system but it's been pretty solid, I've never had to restart a unit or anything like that. I have my own router, always keep the wifi separate. I have a busy local network, about 150 reserved IP addresses, and another 20-30 on DHCP. Maybe a quarter of that stuff is on wifi. If you dont need any specialist features it's very good, and costs about a third of what the eero does.
