En son macOS Sierra'yı çalıştıran Macbook Pro'mda iki saniyede bir yüksek wifi gecikmesi yaşıyorum.
Eski yönlendiricimin suçlu olabileceğini düşündüm, bu yüzden yeni bir tane aldım. Ancak yeni yönlendirici, gecikme sorunlarından yaklaşık% 20 paket kaybına kadar işleri daha da kötüleştirdi. Bu çözümü başka bir Süper Kullanıcı sorusundan denemek , en azından paket kaybını tekrar 0'a düşürdü, ancak gecikme sorunu devam ediyor.
- Kablolu ağ üzerinden aynı yönlendiricinin başka bir makineden pinglenmesi sabit 2 ms ping ile sonuçlanır.
- Wifi üzerinden telefonumdan ping, sabit bir 4ms ping (eski Android telefon) ile sonuçlanır.
- Ağımda aynı testleri yapmak aynı sonuçları verir. Sorun olarak Macbook Pro'nun wifi'sini seçtim.
İşte speedtest.net'ten bir grafik. Bu testi wifi üzerinde her çalıştırdığımda aynı sonucu alıyorum: indirme hızında ~ 5 saniyelik bir düşüş.
Yönlendiricime MBP'mden (varsayılan 1 Hz'de) 192.168.1.1'de ping işlemi yaparken, aşağıdaki kalıbı alıyorum:

Kelimeler: ~ 5 saniye normal ping, sonra ~ 5 saniye ciddi gecikme sorunları veya ping frekansı yeterince yüksekse zaman aşımı.
Yeni bir uygulama yüklemesinin buna neden olup olmadığını anlamaya çalıştım, bu yüzden zaten çoğu uygulamayı devre dışı bıraktım (Dropbox, Little Snitch). Şimdi seçeneklerim tükeniyor. Ping yaparken Wireshark'ı çalıştırdım ve bu pingler dışında hiçbir ağ etkinliği göremiyorum.
Bunu anlamaya çalışabileceğimden emin değilim.
