Slow connection..!!!

Augusto · 12-12-01, 08:17 PM

hey ..have a very slow download and upload.. i know my international channel is 25 up. and around 60 , but still think is too slow... does the tweaks work for me???

This is what i've got

TCP options string = 020405b40103030001010402

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) = 1460
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 1460
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 58.4 kbps (7.3 KBytes/s) @ 200ms
Your RcvWindow limits you to: 23.36 kbps (2.92 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 114 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Thanks

good lord no wonder your defaultrcvwindow is EXTREMELY low try 513920 as the value

Well , i tried others rwins and i recieved this

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) = 1456
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 182
RWIN is invalid

bandwidth * delay product:

RWIN is invalid

Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON

Time to live left = 50 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

what's wrong whit it???

Hi.

Make sure that your tcp1323opts value in registry is equal to "1".
More Importantly, make sure it is a string value rather Dword, because having a string value is neccessary for having high RcvWindow values, as 513920 (which is mine).

Like TCP13230pts i have valor = 1 , but have a string va. , and a dword value.

Do i have to erase the dwprd valu?????

Use the speedguide optimiser and use it to tweak. The Beta 3 test is on the top of the forums.

Pure English

your problems is Default Receive Window (RWIN) is set at a LOW AS HELL value, change it bro

Didn't he/she said that he tried to change it but was unsuccessful on his reply?
