I recently bought a TP Link BE230 for £100 to replace my plusnet hub. It's plugged directly into the ONT. I have some firesticks and found my phone fire TV app was not picking them up easily. With the TP link they are instantly found. Wifi speeds are faster, but do drop off with distance. It also has a 2.5Gb port which may come in useful at some point. I did look at the BE550, but it's double the price. There are probably cheaper and more configurable options, but I'm happy enough. TBF the flint 2 does look decent for not much more and is 4x4 vs 2x2. I just wanted to go cheap until wifi 7 properly arrives and I'm in the process of trying to wire up my home, so I don't know what will be my best option once I have a wired backhaul.
