Increase Your Cable Modem or DSL Speed in XP
This tweak is for broad band cable connections on stand alone machines with WinXP
professional version - might work on Home version also. It may also work with networked
machines as well.
This tweak assumes that you have let WinXP create a connection on install for your
cable modem/NIC combination and that your connection has tcp/ip - QoS - file and print
sharing - and client for Microsoft networks , only, installed. It also assumes that
WinXP will detect your NIC and has in-box drivers for it. If it doesn't do not try
this.
· In the "My Network Places" properties (right-click on the desktop icon and choose
properties), highlight the connection
then at the menu bar choose "Advanced" then "Advanced Settings". Uncheck the two
boxes in the lower half for the
bindings for File and Printer sharing and Client for MS networks. Click OK.

· From the Windows XP CD in the support directory from the support cab, extract the
file netcap.exe and place it in a
directory on your hard drive or even in the root of your C:\ drive.

· Next, open up a command prompt window and change directories to where you put
netcap.exe. then type "netcap/?".
It will list some commands that are available for netcap and a netmon driver will be
installed. At the bottom you will
see your adapters. You should see two of them if using a 3Com card. One will be for
LAN and the other will be for
WAN something or other.

· Next type "netcap/Remove". This will remove the netmon driver.

· Open up Control Panel->System->Dev Man and look at your network adapters. You
should now see two of them and one will have a yellow ! on it. Right-click on the one
without the yellow ! and choose uninstall. YES! You are uninstalling your network
adapter, continue with the uninstall. Do not restart yet.

· Check your connection properties to make sure that no connection exists. If you get
a wizard just cancel out of it.
Now re-start the machine.

· After re-start go to your connection properties again and you should have a new
connection called "Local area connection 2". Highlight the connection, then at the menu
bar choose "Advanced" then "Advanced Settings". Uncheck the two boxes in the lower half
for the bindings for File and Printer sharing and Client for MS networks. Click OK.

· Choose connection properties and uncheck the "QOS" box.

· Re-start the machine.

After restart enjoy the increased responsiveness of IE, faster page loading, and a
connection speed boost.
Why it works, it seems that windows XP, in its zeal to make sure every base is covered
installs two separate versions of the NIC card. One you do not normally see in any
properties. Remember the "netcap/?" command above showing two different adapters? The LAN
one is the one you see. The invisible one loads everything down and its like your running
two separate cards together, sharing a connection among two cards, this method breaks
this "bond" and allows the NIC to run un-hindered.
Use a Shortcut to Local Area Network Connection Information
Something new in Windows XP, instead of using the command line program and typing
ipconfig to find local area network information, you can use the following shortcut:

· Click Start, point to Connect to, and then click Show All Connections.

· Right-click the connection you want information about, and then click Status.

· In the Connection Properties dialog box, click the Support tab. For even more
information, click the Advanced tab.
To automatically enable the status monitor each time the connection is active, in the
Connection Properties dialog box, select the Show icon in taskbar notification area when
connected check box.

Js sm ze slisu za to. Winsi rezervirajo en del resourcov mrezne kartice, da je vedno na voljo nekaj viska. Posledica tega je, da mrezna kartica ne more nikoli delovati s polno paro.

Meni se vseskupaj slisi bolj kot potegavscina.
Nekaj pise o 3com-u, se pravi naj bi bila zadeva specificna za mrezne kartice od tega proizvajalca ali kaj?
Pa tudi zakaj niso vkljucili nekih testov, ki bi dokazovali povisano hitrost, ce jim je res uspelo kaj takega dosezti.

Namesto takih objektivnih podatkov pa navajajo:
"After restart enjoy the increased responsiveness of IE"
Hja, ocitno tega ne bom nikoli obcutil, ker uporabljam drug browser. :p

Verjamem, da se najbrz da potweakati kar nekaj parametrov v zvezi s TCP/IP-jem ter tako kaj malega pridobit, vendar
pa sklepam, da se to naredi v nastavtivah (oz. registry-u) ne pa z odstranjanjem neke
"fantomske kopije" mrezne kartice. Pa tudi QoS je uporabna zadeva in nekako argumentu, da brez tega deluje
vse hitreje, ne verjamem najbolje.

Tako velike bedarije, kot je zgornji članek, je potrebno zatreti takoj in v kali!

Za več informacij o temu, kako v Windows XP deluje QoS je na voljo na naslovu http://support.microsoft.com/kb/316666. Najbolj pomenljiv pa je kar končna točka, kjer je dobro povzeto bistvo celotnega članka: "There have been claims in various published technical articles and newsgroup postings that Windows XP always reserves 20 percent of the available bandwidth for QoS. These claims are incorrect."

Kar se a tiče tistega kobajagi "skritega" vmesnika, pa je to samo posledica načina implementacije QoS v operacijskih sistemih od Windows XP naprej (tudi v Windows Server 2003): Packet Scheduler mrežni vmesnik je samo sloj preko fizične kartice, ki dejansko implementira QoS. Ta "skrit" vmesnik pa dobite preprosto tako, da na nastavitvah kartice (Network Properties, interface properties) dodate še servis "QoS Packet Scheduler". Če ta servis dodate, se pojavi "skrit" vmesnik, če ga odvzamete, pa se znova "skrije". Skratka čista bedarija. Avtor besedila je videl neke posledice, umislil si je nekakšno razlago, ki naj bi pojasnila, kar je videl, zaradi tehničnega neznanja pa je brcnil tako zelo v temo, da bi težko našel podobno primerjavo. OK, morda bi se dalo primerjati z pojasnilom, da strele povzročajo jezni bogovi, Microsoft pa nam krade pasovno širino

Celoten članek je navadno nakladanje brez kakršne koli tehnične podlage, kaj šele, da bi bilo v besedilu skrite kaj resnice. Edino, kar dam avtorju v dobro je to, da si z upoštevanjem navodil ne naredite nikakršne škode, če si že koristi ne morete. Na žalost niso vsi "nasveti" tako benigni.
