ciao a Tutti

innanzi tutto grazie per l'aiuto
Ho eseguito il test su speedguide, e se i valori sono i medesimi per ogni scheda di rete qui sotto sono elencati.
Confermo che ssid è identico, se rieseguo scansione e accoppiamento tra PC e rete ma non ottengo nessun miglioramento.
Sull'impostazione della scheda di rete il canale selezionato è 11






TCP options string = 0204059c01010402
MTU = 1476
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1436
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 64620
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 64620

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
505472 (MSS x 44 * scale factor of 8)
252736 (MSS x 44 * scale factor of 4)
126368 (MSS x 44 * scale factor of 2)
63184 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 2584.8 kbps (323.1 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1033.92 kbps (129.24 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 122 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000
