After setting TCP Window to 128480, do a tracert to http://www.yahoo.com and post.

The earlier tracerts do show some interference over the wireless transmission (hop 1) but may be due to the very high TCP Window then.

it doesn't much matter that Tcp1323Opts = 0 or 1, something overwrite the tcpwindowsize to 65536 even i setted it to another value before reboot

piranha

i am testing rwin to increase internet speed but got a strange problem.

I tried some numbers lower than 65535, set same value for GlobalMaxTcpWindowSize and TcpWindowSize in Cablenut, with tcp1323Opts = 0 and other higher than 65535 with tcp1323Opts = 1

Can anyone tell me why these f*** number ...

I already know that but my ISP limits the mtu. I know too it is rare with cable but it is confirm by tcpoptimizer largest mtu test

Just dont understand why i set all to 1496 and my analyser result show 1500 ???

piranha

thanks

piranha

tech support of my cable ISP suggest me to use a mtu of 1496. TcpOptimizer confirm the 1496 mtu. I set the mtu in windows xp (with Cablenut) and for my router (yes i did save...) to 1496 and still got these result

Cause for slower upload speed may either be the presence of spyware or problem with the cable modem.

Scan for spyware and check modem log on power levels and SNR.

With 513920 last night, my dowload speed increase up to 6400 but my upload speed decrease to 3xx to 5xx kbps

ISP continue to increase internet speed around here

Videotron 7 Mbps
Cogeco 10 Mbps

Can we still stay lower than 65535 for tcpwindows values (dsl or cable) ????

There is no "bug" in the TCP Analyzer. It simply reads and reports the one and only TCP Window value in packets on the internet.
