Recent XP update = slow Internet???

I am working on access speed issues since March 12, 2009. I got two
PCs that use a 7Meg DSL service via a broadband router. None receive
a reasonable upload access speeds (21 Kbp/s or less) thus rendering
most web pages to time out and several emails to not be sent. I got
DSL service to be checked and the phone line verified. All is
correct. I have checked and may sure both PCs are free of malwares /
viruses.

Now my question is: Has there been a recent update to XP that would
change the TCP/IP Ethernet networking so as to restrict access speeds?

Hi
Did you checked the TCP/IP parameters (MTU, RCwin) to make sure that they
are for optimal performance with your type of Internet connection?

I'm trying to find out why "something" changed on March 12.
Everything before worked find but since March 12, I have "pre-analog
-- less than 50K access speeds on a 7 Meg DSL service.

The "tweak" tests from DSLREPORTs report every thing is correctly set.
