I called my cable provider today and asked what iI was capped at he said 300/1520 does this make sence? I use Adelphia and have been getting some major packet loss with they said was only 2% at 2:30 a.m. . Any thoughts on what i should do? Thanks

MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.
Default Receive Window (RWIN) = 513920
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

question...
The caps sound about right 1500 kbps download and 300 kbps upload. If you're getting packet loss of 2% then you should lower your RWIN. If running XP try 29200. If 9x or ME try 51100.
