2. General Questions

If you are getting stalls when using your PC Before your new ADSL line has been activated, your new internal ADSL card could be attempting to talk to the network (which is not yet configured for you), and while it does this, your PC may freeze. The solution is to remove the drivers for the card and/or the card itself until the ADSL line is activated by the Telco, then re-install from scratch.

If your PC is freezing regularly, and you are on PPPoE, your computer may be looking around for a DHCP server that does not exist. Check the following: (windows)
• Open control panel, open Network
•For Windows 2000/XP, instead, do -> Start -> Settings -> Network and Dial-Up Connections, and then go into the Properties for your Local Area Connection
• Look for the first entry in the scroll box marked TCP/IP that is associated with a hardware ethernet card (ignore dialup, AOL and VPN type bindings).
• Select it and press properties
• Select IP address from the tab
• Is Obtain IP address automatically checked? If so, change that to Define IP address and enter 192.168.1.10 and 255.255.255.0 into IP address and subnet mask fields respectively.

This assignment of a harmless local IP address to the TCP/IP settings bound (connected) to your network adaptor will stop the in-built DHCP services from waking up every 10 minutes to look for a DHCP server so that it can "fill in the blanks."

If you are using Win98SE, also use this update: Windows 98 Second Edition Problems with NDIS Intermediate Drivers.

  • I have tried this tweak and with the settings you provide I do not have any internet connection. Have I miised something obvious?

PPPoE stands for Point-to-Point Protocol over Ethernet.

PPPoA stands for Point-to-Point Protocol over ATM (Asynchronous Transfer Mode)

Feedback received on this FAQ entry:
  • Cable does not use PPPoE or PPPoA.

  • It would be nice if you could explain whether or not cable is a pppoe or not. Thanks for doing what you do though.

Simply stated, NO.

Ping is latency on the Net, and not your computer, therefore it can not be lowered. Latency changes every second on the Net, with the pulse of its many users.

Lowering ping by adjusting RWIN is simply an urban legend and not true, as RWIN and ping use two totally different protocols.

If you lower MTU, the latency of your packets should improve, though your download speed will decrease as well. Some gamers prefer this course of action, though.

A bad NIC, modem, etc may also be the cause of high ping. These must be replaced by the user.

Tweaking is a term used to denote improving one's system performance. Here in the Tweaks Forum, we strive to improve your download speeds (upload can not be adjusted) as much as possible, as well as to fix other TCP/IP (speed-related) problems that you might have.

The two things to focus on most are your RWIN (Receive Window) and MTU (Maximum Transmission Unit) settings. These two are truly about the only things that affect speed.

The Tweaks Forum prides itself in assisting users on a one-on-one basis, as opposed to simply telling you to download something (such as a "speed patch") to do it for you. Every user's line can be different, thus the tweak being different, too.

A: Power-cycling your modem is similar to doing a warm boot of your computer. By power-cycling, you are essentially resetting it.

Here is how to do it:
1) Turn the modem off (if no switch, simply unplug it) for 45-60 seconds and unplug it from your phone line.
2)Reconnect the phone line and turn the modem back on (or plug it back in), being sure that it is not near anything that emits EMI (see this FAQ 3078 for details), such as CPU, monitor, TV, speakers, lamps, radios, etc.

But I have an internal modem. Can I power-cycle it?

Yes.
1) Power down your computer.
2) Unplug the modem from the phone line.
3) Wait 45-60 seconds, reconnect phone line and reboot you computer.

Sometimes, when you try to connect to a website, the connection attempt "times out" due to the slowness of response, and you get a "Could not connect to ... "

If you frequently encounter this problem and wish to wait for the connection anyway, then here is the cure. It will apply to all sites, though you will still have the option of clicking the Stop button. THPC is too busy (!) to use this tweak, but testing confirms that it works.

1. First, backup the Registry.

2. Run RegEdit and navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net

3. In the left pane, locate the 0000 Key (or 0001, 0002 or 0003) that represents your modem or NIC.

4. Under that Key, locate the Value name called "SLOWNET" (right pane).

5. Double click on SLOWNET and change "Value data = 01" (zero & one) to "00" (two zeros).

6. Close RegEdit and reboot.

Feedback received on this FAQ entry:
  • The FAQ says to use regedit for this key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net I wanted to try it out because I constantly get the server busy message when I'm browsing. The problem is I don't have "class" under the services part. It's just not there.

  • I can't find the reg file, the system tab doesn't exist on mine. Im running xp pro sp3

    2009-04-15 08:31:44

  • I wish there was a little more information about this change. Does it apply VISTA or is this just for XP and 98 or just 98? I am changing the slownet value from 01 to 00 to increase the wait time but what am I changing it from? What am I changing to? What if I don't find this regedit location or value? Thanks!

Downloading and uploading files is like transferring a dirt pile from one location and placing it in another. The dirt pile is the IP (Internet Protocol). The place where you want to move the dirt pile is the other IP. The process of moving the dirt to the other location represents the TCP (Transmission Control Protocol). The wheelbarrow you will use to move the dirt is the MTU (Maximum Transmission Unit). The amount of dirt you put into the wheelbarrow is the RWIN (TCP Receive Window). If you put too much dirt into the wheelbarrow, it could be heavy, even spilling on the ground -- that's the Packet Loss. If you would place less dirt in the wheelbarrow, it will be easier to haul it and you can move faster; the only catch with this is that you will have to make a few more trips in order to complete the task. As you see, you have to find that medium with the loads of dirt to the round trips to each dirt pile.

When viewing the list of components for a network interface, you may notice that the Uninstall button is disabled when Internet Protocol (TCP/IP) is selected. In Windows XP, the TCP/IP stack is considered a core component of the operating system; therefore, it is not possible to uninstall TCP/IP in Windows XP.

In extreme cases, reinstalling the Internet Protocol stack may be the most appropriate solution. With the NetShell utility, you can now reset the TCP/IP stack back to a pristine state, the same state as when the operating system was installed.
