I'm running the Beta version of SM on a new RPi 4B, 4GB. So far it's working really well, connects to all my equipment perfectly and has been very stable. I'm testing the networking, trying to find the best/fastest connection possible. Obviously, the less extra gear I need and the fewer the cables, the better. I discovered that SM is only connecting with WIFI using wireless N at between 58 to 72Mbps. I have a wireless AC adapter on my laptop, and the RPi supports wireless AC, but refuses to connect using that protocol, only the slower N.
Is there a way to force SM to use 802.11ac for the fastest wireless networking?
FWIW, here are the three networking methods I've experimented with, all seem to work reliably while testing in my office:
1) Gigabit ethernet from SM to router, gigabit ethernet from router to laptop. 21MB images from my Canon T3i download in about 5 seconds.
2) Gigabit ehternet from SM to router, wireless AC from router to laptop (getting 433Mbps between router and laptop, downloading 21MB images takes about the same 5 seconds, maybe a fraction of a second slower.
3) Hotspot mode connecting completely wireless from SM to laptop, wireless N only (can't get SM to use 5Ghz AC) getting 58 to 72 Mbps, 21 MB images take about 10-11 seconds to download.
