TCP Optimizer Settings for XP?

Sting · Post by **Sting** » Thu Apr 17, 2008 11:51 pm

Hi, I have a question; maybe someone could be kind enough and help me out?

I’ve been using TCP Optimizer 2.0.2 for a while now, with Windows 98SE. Well, after using 98 for years and knowing it inside and out, I finally decided to upgrade to Windows XP. I’ve only been using XP for a few days, so I really can’t say if I like it better then 98. Anyways, what are the correct settings for the TCP Optimizer with XP? At the moment, there’s nothing listed for: (TCP Receive Window, MTU, Max Duplicate ACKs, Time To Live (TTL) or TCP 1323 Options)! My I.P. speeds are: 5000 Down, 500 Up.

Any help would be appreciated.

Thanks for your time,

John

XP Home or XP Pro? (XP Home Edition, Version 2002 Service pack 2)

Which country are you in? (United States)

Post your TCP Analyzer report. (This is a silly question, but due to health issues, I haven’t been to the forum in along while. Where on the website can I find the TCP Analyzer to run it)?

Thanks for your help!
