Hi Jean-Roch, I got a new firmware-rpi-nonfree.lrp from K.P.Kirchdoerfer, and that works fine with the built-in wifi in the RPi. I don’t think this has made it to 7.2.2, but I expect it to be in 7.2.3. I have been testing speeds with iperf3. I was running the server on my local network on an iMac 27” from 2014 that works perfectly. The Raspberry Pi: /etc/issue: Linux 5.15.93-cortex72 #1 SMP Sat Mar 25 20:50:12 CET 2023 LEAF Bering-uClibc 7.2.1 Rev 1 uClibc 1.0.42 My network supports 1 Gbit speeds, both wired and wifi. When I run iperf3 as a client from my Raspberry Pi I get the following results: Ethernet connection (/dev/eth0): Accepted connection from 192.168.22.42, port 33564 [ 5] local 192.168.22.6 port 5201 connected to 192.168.22.42 port 33568 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 64.1 MBytes 537 Mbits/sec [ 5] 1.00-2.00 sec 65.1 MBytes 546 Mbits/sec [ 5] 2.00-3.00 sec 65.0 MBytes 545 Mbits/sec [ 5] 3.00-4.00 sec 65.7 MBytes 551 Mbits/sec [ 5] 4.00-5.00 sec 65.0 MBytes 546 Mbits/sec [ 5] 5.00-6.00 sec 65.4 MBytes 549 Mbits/sec [ 5] 6.00-7.00 sec 64.9 MBytes 545 Mbits/sec [ 5] 7.00-8.00 sec 64.9 MBytes 544 Mbits/sec [ 5] 8.00-9.00 sec 65.5 MBytes 549 Mbits/sec [ 5] 9.00-10.00 sec 65.3 MBytes 548 Mbits/sec [ 5] 10.00-10.01 sec 1003 KBytes 557 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate [ 5] 0.00-10.01 sec 652 MBytes 546 Mbits/sec receiver ————————————————————————————— Using wifi (/dev/wlan0): Accepted connection from 192.168.22.159, port 36702 [ 5] local 192.168.22.6 port 5201 connected to 192.168.22.159 port 37118 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 6.93 MBytes 58.1 Mbits/sec [ 5] 1.00-2.00 sec 6.82 MBytes 57.2 Mbits/sec [ 5] 2.00-3.00 sec 7.55 MBytes 63.4 Mbits/sec [ 5] 3.00-4.00 sec 6.57 MBytes 55.1 Mbits/sec [ 5] 4.00-5.00 sec 5.24 MBytes 44.0 Mbits/sec [ 5] 5.00-6.00 sec 6.41 MBytes 53.8 Mbits/sec [ 5] 6.00-7.00 sec 7.67 MBytes 64.3 Mbits/sec [ 5] 7.00-8.00 sec 7.53 MBytes 63.2 Mbits/sec [ 5] 8.00-9.00 sec 7.83 MBytes 65.7 Mbits/sec [ 5] 9.00-10.00 sec 7.57 MBytes 63.5 Mbits/sec [ 5] 10.00-10.03 sec 204 KBytes 65.4 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate [ 5] 0.00-10.03 sec 70.3 MBytes 58.9 Mbits/sec receiver ----------------------------------------------------------- So there is an almost 10x difference between wired and wifi performance on the RPi. I am sure this is not a performance you want on the wifi for a firewall. I have been using the different versions of the APU/APU2 platform for many years. But there are alternatives today. Right now I use for my home firewall an Intel based unit, Qotom Mini Pc X86 4 Lan Gigabit With Celeron J1900 and VGA, I bought it through aliexpress.com. Of course, this has now been updated to a newer model. You can now get a Fanless Router Celeron J4125 Mini PC Quad Core 4x Intel i225/i226 2.5G LAN with HDMI and VGA for 115 EUR. This is without RAM and SSD.
