    Prob with RWIN,halp pl0x

    I have recently taken a WiFi connection with a kind of antenna and LAN card...

    but the problem is,everytime I try to tweak the RWIN setting (cuz it's really low)
    and analyze it,it always says it's still that low setting,but the optimizer says it's at the RWIN value I set it at.

    after taking this connection,I noticed a significant latency improvement since my last connection,which sucked badly....but the problem is,whenever I go into any kind of situation in an online game with multiple players involved,I get HUGE lag spikes...

    I was thinking,is this the result of my RWIN window not being 'wide' enough?

    I need some answers,Haaalp....someone explain why my RWIN just won't change,

    Guys,I just can't seem to get a change in my RWIN,everytime I try to change it and go check it on the TCP Analyzer,but everytime my RWIN is the same,at a number too small...

    So...any thoughts on what I can do or at least on what's causing it?

    um....wonder if I'll get an answer to anything...

    but,I'm using a RAlink chip and it has an option 'Enable TCP Window Size'

    what does it mean?I'm rather confused

    and I need to know if NAT or something is keeping me from changing my RWIN TCP Window Size value,
