I have a WAX202 running OpenWRT 22.03.3, connected over gigabit ethernet to my Protectli VP2410 router, which provides gigabit routing for my FTTH Internet. I'm able to saturate the connection over ethernet. iperf3 throughout my wired network reaches the usual 940 Mbit/s. Every device on the network can reach those speeds without issue.
The only bottleneck is the WAX202, so I'd like to upgrade to something faster. I've done some searching and reading on the forums (particularly in this stickied thread) and it looks like the Linksys E8450 may be the best choice for OpenWRT right now for saturating my gigabit network over wifi. Are there other options? I also briefly looked at the Banana Pi BPI-R3, though I'm not sure of its performance. I was considering the Banana Pi BPI-W3 but it appears you need both Windows and a soldering iron to install an OS on that board, and I have neither.
I specifically and solely want a dumb AP. As I said above, I've made the investments throughout the rest of my network (router, switches, cables, clients) which the above thread outlines for gigabit, and the Protectli can still saturate my connection while doing NAT. The only bottleneck is my wifi. I'm happy to invest in expensive hardware to maximize my speeds. In terms of availability, I'm in the US, but am comfortable ordering from e.g. AliExpress or something else. I only have two real requirements: speed and quiet. I'd prefer something fanless, but something mostly silent like my NUC is fine, too. x86 is fine, I just want faster wifi. I'm not afraid of building OpenWRT from source, or applying custom patches, or even installing a generic Linux distro and configuring from the ground up; I just want faster wifi and I'm willing to spend the money and do the work for it.
