MacBook無印で使ってきたDockはPower Delivery専用なので電源供給がUSB-CでないMacBook Air M4で使えるのかどうか解りませんでした．とりあえずDockをつないで，LANに接続したら使えました．<\/p>\n\n\n

そこで，有線LANで速度計測をしてみました．前回のWi-Fiと同じこと<\/a>を有線LANで行いました．<\/p>\n\n\n\n

わが家の有線LANは最大1Gbpsなので，いずれのテストサイトの測定結果もダウンロードの速度はWi-Fi<\/a>に負けますが，RTT (Latency)とJitterが小さいです．<\/p>\n\n\n\n

あとは電波を出さないのがいいです．<\/p>\n","protected":false},"excerpt":{"rendered":"
