thanks for the response. i did what you advised but my speed did not really change (i loaded the tweak into cablenut and restarted). Here are my tests
on testmy.net my speed ranges from 2.2 (most of the time) up to about 3.6 (rare). Not even close to my advertised speed
When using https://www.speedguide.net:8080/, i got
TCP properties for IP = **.**.**.** ()
Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.1) Gecko/20060111 Firefox/1.5.0.1
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405b40103030401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default TCP Receive Window (RWIN) = 824320
RWIN Scaling (RFC1323) = 4 bits (scale factor of
Unscaled TCP Receive Window = 51520
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 32972.8 kbps (4121.6 KBytes/s) @ 200ms
Your TCP Window limits you to: 13189.12 kbps (1648.64 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 56 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
