STA waiting for IP #84

Open tpacini opened 7 months ago

tpacini commented 7 months ago

I have two Raspberry Pi 4 Model B (STA and AP) with Raspbian OS (32 bit) installed, connected to the Wi-Fi HaLow AHPI7292SA boards. I followed the guide and, after replacing the file nrc7292_bd.dat with the one from issue #60 (to solve the target mismatch error), I ran the start.py script on AP:

But the station is stuck on "Waiting for IP" message. The only thing I noticed is that the AP has no IP address on wlan0 interface, so I assume the hostapd is not working somehow.

tpacini commented 6 months ago

I was able to configure both the AP and the STA by installing an older version of Raspbian OS (release 2022-04-04, kernel 5.10). Now the problem is that when I run a test with iperf3 I get a large UDP packet loss that decreases with higher MCS indexes.

The setup is as follows:

iperf Done.

I also tried with iperf3 3.15, since the installed version is 3.6 without improvements.

Different parameters:

Limiting the bandwidth to 100k reduces the losses to 0%. Higher bandwidths lead to higher losses (> 20%).

I increased both w/rmem and udp_w/rmem buffer values without any significant improvement.

I tried to find out the number of packets actually sent from the NIC to the other end, and ifconfig wlan0 shows that the STA sends all the packets, but the AP receives only some of them (close to (364 - 242)), no dropped packets or errors. However, based on ethtool -S wlan0, the STA is sending some of the packets that are fully received by the AP.

I saw that ifconfig gets its values from /sys/class/net/wlan0/statistics/, while I couldn't find where ethtool gets this information.

I also set up a pfifo queue and all 410 packets go through it without dropping.

Which statistics can be trusted? Is ethtool supported by the drivers? Shouldn't the packet loss increase with higher MCS (e.g. 6,7)?
