SBC DSL help

Hello,

I am running Windows XP Pro SP2 with SBC DSL 512k download speed but i am getting slow speeds. i have installed the p2p fix. here is the test data:

Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5

Notes: Read the Analyzer FAQ if the above is not your IP address.

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 your MTU value.

Default Receive Window (RWIN) = 65535

RWIN Scaling (RFC1323) = 0 bits

Unscaled Receive Window = 65535

Note: TCP 1323 Options need to be enabled for RWIN over 2^16 (65535). Windows 9x might also need the MS Vtcp386 fix.

For optimum performance, consider changing RWIN to 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: 2621.4 kbps (327.675 KBytes/s) @ 200ms

Your RcvWindow limits you to: 1048.56 kbps (131.07 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 (0)

hello  :D  i think that you are on the 1.5mb down 384up dsl express package.  That is normal speeds for that package.  i have been reading about dsl myself.  there is an overhead which reduces speed somewhat so i am pretty sure you are getting the correct speed.  however if you are on the pro package you should see higher speeds.  i am having cable internet speed problems myself.  i have been trying to get dsl for a while but so far they haven't activated the remote terminal in my area.  If express is the package that you have then those speeds are very good.
