I have a 4 Mbps speed PPPoE broadband connection. But the browsing speed is very slow.
I used TCP/IP optimizer 3.0.6 and changed the MTU to 1492 and RWIN to 249920.
I used TCP/IP Analyzer to check the values. It still shows MTU as 1460 and RWIN as 65536.
Could somebody please let me know why the values of MTU and RWIN are not changing and how to change them ?
