@solidcore I am currently running a 902 as an access point connected to my home router, and a 902 as a client connected to my music server:
Home router -> wired ethernet on port configured as a dedicated audio subnet -> 902 running OpenWRT and configured as an access point with audio WiFi network -> WiFi -> 902 running OpenWRT and configured as a client -> throttle cable -> Taiko network stack -> Taiko Olympus
On my 902 AP, I removed DHCP and all firewalls and configured it as a low power access point (1mW/3dbM). On the 902 client, I connected to that AP SSID, again with a low power radio setting (1mW/3dbM). For me, there is no conflict with my other WiFi networks.
This morning I finally converted all my 902’s to 3.3V so I was able to do some direct A/B testing with the Ian Canada battery supply and UcConditioner.
For me, a 902 client running OpenWRT was a clear step up from a 902 client running the original TP link firmware. I’m attributing this to the lower radio power of 1mW vs 10mW on the „low power“ setting on the original TP link firmware, but that is a guess on my part.
With my 902 running OpenWRT as an access point, there was also a clear step up when going to a USB battery pack and then again to the Ian Canada 3.3V supply. The 902 access point in all configurations was better than my home WiFi (Ubiquiti mesh network). Alas, what is upstream of the 902 client still matters here.
My OpenWRT configurations are in the links above, but happy to discuss/share here if of active interest
Best holiday wishes to everyone, and all health and joy in the New Year!
