I got SP1 about two weeks ago, for my Windows XP
Professional. The download was completed fine, and it was
installed successfully.

However, when I connected to the internet (I use ManxNet
Click Freedom, a monthly charge 56k connection) it showed
up as connecting at it's maximum BPS, 112560. I lowered
it to 57600, but it is still having problems. If I;

Go on hotmail
Use MSN6
Log in to my Microsoft Passport
Download/Upload Large files

It disconnects the internet without warning, and shows
a "No help topic associated with this item" message if I
try to diagnose it. Even if I do not do any of these
things, it will still clock up errors (sometimes up to
400) and then disconnect me after time.

Does anyone know what is going on?
 
is MUT issue? quoted from http://www.ChicagoTech.net
Can't access some web sitesSymptoms: 1) If you're using MS ICS or Windows
server as router to access the Internet, your clients may not be able to
access certain web sites. However, the ICS host or the server doesn't have
this problem.
2) After installed a new router or cable modem replacing dial-up to access
the Internet, you can't access some web sites.
3) You also find that most web sites you can't access are block to ping or
they are security sites using HTTPS.

Causes: 1) The problem occurs because many web servers block ICMP messages
and the packets are dropped. As a result, the requested web site doesn't
load.
2) This problem is caused also by an incompatible MTU networking setting.
You may try to install the latest SP. If you use MS ICS, you may want to
configure all your Client computers to use the new, lower MTU as the default
for all Internet communication. To modify the MTU size, locate the following
registry key: HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\
Tcpip\ Parameters\ Interfaces. If you use a router like Cisco DSL Router,
you may want to adjusting the PPPoE MTU Size. For example, to adjusting the
PPPoE MTU Size on the Cisco DSL Router, do

interface ethernet0
no shut
ip address <ip address> <subnet mask>
ip adjust-mss 1452
