hi my dsl is 1.5Mbit/128kbit and when im dling stuff my download speed always stops at 150kb/sec. is there a way to uncap this? my friend said he accomplished this but i dont believe him. can anyone help? thanks alot

TCP options string = 020405ac01010402
MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

Default Receive Window (RWIN) = 65340
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65340

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 2613.6 kbps (326.7 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1045.44 kbps (130.68 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 118 hops

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

For one thing, you can't uncap a DSL modem. Your speel is controled at the CO (Central office). In order to get a faster speed, you would have to break in, and figure out how to work the computer to change your speed.

You CAN uncap a Cable modem, but it is illegal, and most ISP's will notice that you have uncaped your speed (Unless you only did it by 500kb/s) and they can fine you, etc.

coin 150k is 1.5Mb and you wont get any faster unless you get a faster connection... Dsl is 1.5 megabits not 1.5 megabytes there is a 8 to 1 difference so that means that for every 8bits it would equal 1byte, so in other words you are getting close to what your dsl provider advertises which i am sure it may be 1.4Mb and not 1.5Mb... but here is the calculation for your connection asuming it is 1.5Mb... 1500 divided by 8 = 187.5 <--some of that is overhead and you dont really see it when downloading a file...
so accually you got a good connection since you are getting advertised speeds... :thumb:
