私のRaspberry Pi 4 Model Bを次のいずれかで使用しようとしています。このModMyPiはRalink RT3070チップセットに基づいています。USBワイヤレスアダプタはAPに転送されますhostapd。
私が直面した問題は次のとおりです。
- スタート
hostapd - APが正常に動作します（DHCP / DNS /ルーティングなど）。不確実な期間
hostapd結局、これが起こる理由を説明するのに役立つログに役立つ情報（私が見ることができる）がほとんどなく、競合が発生します。
hostapdこの後、再起動すると再びオンラインになるようです。
USB WiFiドングルは、次のrt2800ドライバファミリを使用して表示されます。

答え1
まあ、RT3070ドングルを数回テストした後、それが設定に関連していることを確かに言うことができますtx-power。
ここにはいくつかの質問があります。
1. CRDA 規制データベースが最近変更されたようです。許可された値のいくつかはEIRPを表すように見え、他の値はまだERPを報告します。
EIRPは有効等方性放射電力に対応し、次のように計算されます。
EIRP(dBm) = [Output Power] - [Cable Loss] + [Antenna Gain]
iw reg set AUオーストラリアの国コードを使用している場合は、iw reg get次の出力が表示されます。
global
country AU: DFS-ETSI
(2400 - 2483 @ 40), (N/A, 36), (N/A)
(5150 - 5250 @ 80), (N/A, 23), (N/A), NO-OUTDOOR, AUTO-BW
(5250 - 5350 @ 80), (N/A, 20), (0 ms), NO-OUTDOOR, DFS, AUTO-BW

(57000 - 66000 @ 2160), (N/A, 43), (N/A), NO-OUTDOOR
最初の行には以下が表示されます。 （2.4GHz周波数帯域@40MHz)、(該当なし、電力伝送）、つまり、チャンネル選択が1〜14チャンネルの範囲にある場合、最大送信電力設定はです36 dBm。以下を実行して簡単に確認できます。iwconfig wlan0 txpower 36
wlan0 IEEE 802.11 ESSID:"[SSID]"

Link Quality=61/70 Signal level=-49 dBm

Tx excessive retries:402 Invalid misc:3418 Missed beacon:0
ただし、ACMA（FCCのAUバージョン）あたりのオーストラリアの規制ドメイン制限は、送信機とアンテナ利得の合計である最大EIRP電力で36dBmを指定します。つまり、36dBmトランスミッタを使用して有利なアンテナを接続することは違法であり、複数の場所でEIRP = 40dBm（36dBm + 6dBi - 1dBmケーブル損失）でラジオを操作すると当局にさらされる可能性があります。注目。
iw reg getAU国コードの異なる値を報告する以前のCRDAデータベース（約1ヶ月前に最後に更新されました）を使用する他のシステムを特定しました。最大送信電力は20dBmです。
これはAUの国コードに限定されず、米国の伝送電力ももともと20dBmから現在の30dBmに上がった。
2. 接続の安定性および送信電力
問題のある価値を見ることはtx-power私たちにとって良い参考点になりますが、それが全体の話を教えてくれません。したがって、次のステップは、さまざまな国の規制領域を使用して、さまざまな送信電力設定で高利得6dBiパネルアンテナを使用して接続テストを実行することです。
実際に記録されたテストは、8.8.8.8AU（36dBm）、BO（20dBm）、およびUS（30dBm）regドメインを使用して、各tx電力設定が10dBmから36dBmまでの単純な5ピンシーケンスでした。
ログでは、TXPOWERはに対応し、iwconfig wlan0 txpower [TXPOWER]tx-power出力の次の行はiwconfig wlan0独自の出力です。 tx-powerが再構成されるたびに、インターフェイスは必要なすべてのsleep 5キャリブレーションを実行するために5秒かかります。
私たち:https://dpaste.com//CRAVMGW8S
オーストラリア:https://dpaste.com//CETUDFVHA
悪:https://dpaste.com//674RUR9TT
ログに示すように、選択した規制ドメインによって非常に異なるtx-power設定でエラーが発生しました。 AUドメインは30dBm未満の接続性を維持できませんが、BOは19-20dBmで最も強い接続性を持っています。同様に、米国でも26dBm未満の接続問題が発生し始めます。
4. インターフェイスの競合と理由
米国ドメインのログを見ると、下部に同じ名前のインターフェイスで競合が発生したことがわかります。その後、パケット損失と（損失+エラー）が発生します。 100%再現可能です。
ifupインターフェイスを使用して再起動してもifdown効果がないため、エラーは一種のスレッドロックに関連しているようです。同様に、値が正しくない場合、tx-power関連するネットワークサービスとネットワーク管理者サービスの両方を再起動しても、インターフェイスはオンラインになりません。
リセットにもかかわらず、インターフェイスはまだ動作しているように見え、iwconfig実際に最大電力（OPiwconfig出力など）を報告することもできますが、そのインターフェイスに接続したりワイヤレス設定を変更したりする方法はありません。
ただし、誰かが次のことを行う場合：
sudo ifconfig wlan0 down
sudo iw reg set BO
sudo iwconfig wlan0 txpower 20
sudo ifconfig wlan0 up
ifconfig wlan0 down**最も重要なステップは、復元する前にtxpowerをリセットすることです。 **
これにより問題が100％解決されます。
5. 36dBmでAUに接続
長期間にわたってこれをテストしませんでしたが、1時間が経過すると、アダプタがより熱くなり、平均ping待ち時間がiw reg set BO20dBmより悪くなるようです。tx-power
