MTU is fully optimized for broadband.

Unscaled Receive Window = 1460
RWIN is a multiple of MSS

Consider increasing your RWIN value to optimize TCP/IP for broadband.

i've already done whatever the FAQ has said and i've changed in the TCP13230 points to 1 and installed the Vtcp.386 patch... can anyone help me out here?

The analyzer cannot read the actual settings in your registry. It gets its numbers from analyzing the packets which it receives. My guess is that your ISP will not negotiate an RWIN larger than 1460. You might try to get another user on the same system to run the test and compare results.

if my isp locks it at 1460... that's bad rite?
but when i go to dsl reports it reads the rite rwin of 64240 which i have set. =\. this ain't good..

In lay terms Sg's analyzer reads what your sending out, DSLR is reading what is in your registry, but since it's not getting out, it means nothing, try turning off proxy if you have it enabled, instructions on help thread below

okay lobo... did everything u said in the great little help section =) but that's what i get after all that... i wonder if it's the usage of my linksys router be giving me this problem? i should have mentioned this earlier about me using the router, sorry...

i tested the tcp/ip analyzer on another comp and i get the same rwin of 1460... does that mean my IP has capped it?

It's the router!

Update it with the latest firmware which I unfortunately don't have!

hehz, it's not the router, went to my friend's place n tested the tcp/ip analyzer on his comp n i get the same readings... direct connection and no router, i removed the router and i get the same readings for what i have with my router
