ThinkCentre M75q-1 Tiny の
WiFi 5 モジュール(intel Wireless-AC 9260)を交換(ダウングレード)しようとして
見た目ちょっとやばそうな螺子だなと思ったんだが他で実績のあるドライバーで
回すと、どんどんなめていく。。
おまけに、余計なアンテナ端子ガードが付いてて、ネジザウルス使うのに邪魔
そのガードをやっと外して、
さら螺子だったけどネジザウルスでするすると廻った
のに感動です!!

Thinkpad L390ですが、
ネットで調べても、
CNVi対応の無線LANカードモジュールしか使えないとの情報はあるんですが、
非CNViカード(Eキーだけ、Aキーなし)が使えたとの情報がありませんね。
試してみました。
何の問題も無く使えましたね。
AX対応のルーターに接続出来ました。
リンク速度: 1201(Mbps) でした。
https://github.com/micropython/micropython/issues/10812
の方と同様の現象発生で、昨日悩まされてました。
You need to close the waiting (bound on port 80) socket, otherwise you won't be able to make a new one on the same port.
しょうがないので、とりあえず、bind(addr)を正常終了までリトライするコード
に変えてみました。
以下、コード例
....
# Open socket
addr = socket.getaddrinfo('0.0.0.0', 80)[0][-1]
s = socket.socket()
##s.bind(addr)
bs="addr"
ec=0
while bs!=None:
try:
bs=s.bind(addr)
except OSError:
ec=ec+1
print("EADDRINUSE?? " + str(ec))
utime.sleep(1)
print('s.bind(addr) rt ', bs)
s.listen(1)
print('listening on', addr)
....
とりあえず、
最悪でも、2分以内に、bind出来た。。
Raspberry Pi 3A+ のOS bullseye(11)に上げました。
いまのところ殆ど問題ないですね。意外!?
