Is is possible to set Quality of Service on packets leaving a Windows XP terminal? Or in other words, can I set the DSCP or IP precedence values on packets belonging to a flow of a certain application?

Yes, you need to have QOS enabled on the network connection.

Increase bandwidth by tweaking QoS
The following tweak applies only to Windows XP Professional edition (and other Windows versions that may have QoS Policy installed).
The default system behavior is that all 100% bandwidth is available, however, if there is a running application that indicates to the OS it needs to send high priority/real time data, then as long as it has the socket open, Windows XP will restrict "best effort" traffic to 80% of the bandwidth so that high priority traffic can be accommodated. Basically, applications can make this request to the operating system for QoS support using the QoS application programming interfaces (APIs) in Windows and this only applies if a specific app is requesting QoS.
If you'd like to change how much bandwidth is reserved for QoS (the default is 20% of the total bandwidth), do the following:
1. Make sure you're logged in as "Administrator" (not just any account with admin privileges).
2. Navigate to START>Run and type: gpedit.msc
3. Navigate to Local Computer Policy > Administrative Templates > Network > QOS Packet Scheduler
4. In the right window, double-click the limit reservable bandwidth setting
5. On the setting tab, check the enabled setting.
6. Where it says "Bandwidth limit %", change it to read 0 (or whatever percentage you want to reserve for high priority QoS data)
7. Click OK, close gpedit.msc
Under START > My Computer > My Network Connections > View Network Connections, right-click on your connection and under Properties (where it lists your protocols), make sure QOS Packet Scheduler is enabled.



Setting the applications priority to high in task manager should if I understood it correctly, give the application also Priority on its network traffic. Or then this priority setting needs to be set elsewhere of which I'm not completely sure at this time.

I have a 802.iin in my windows Xp tower, it works but internet explorer still says offline? Please help


Hi Sarah,
Click on Start.
In the Run box type cmd.exe
This will open the Command line window
In this window type ping yahoo.com
Press the enter key

f2801de3-8dec-4256-8de4-b330799d19b8.jpg

You should see an image like this one above.
If your network card is set up properly you will have TTL (Time To Live) values. If it is not set up correctly you will get Timeout values.
If you want to see if your network card has gotten a good IP adress from your router, stay in the Command window and type ipconfig
If you see your IP address is 169.x.x.x Windows has assigned your IP address and it is not valid on your network.
You need an IP address from your wireless router. This can be manually set by you or delivered via DHCP via your wireless router.
Here is a link on how to do that:

Plz send me the current status of contolling ip spoofing through inter domain packet filters


The current status is "operational" -- packet filtering is being used so that "outgoing" IP-addresses originating from a network are required to be IP-addresses that are valid within that network.

I have 20mb broadband but only 300kbs download speed


I personally have never known that changing the MTU setting can speed up your connection, as the MTU is the maximum transmition units that is sent to your pc from each web site and if the MTU setting is incorrect then some web sites will not load on your explorer page, the speed at which you download the page will not make any difference.

If you are supposed to get 20MB speed then you must be on cable and not ADSL as ADSL is a max of 8MB, so i would ring up Virgin or whoever and check the speed you should really be getting.

See these details posted on the netgear site, and you'll notice there is no mention of speed:-

Details About MTU
A packet sent to a device larger than its MTU is broken into pieces. Ideally, MTU would be set to the same — large — value on all your computers, routers and switches, as well as on all the parts of the Internet that you access. But you cannot control the MTU on the Internet, and in practice the optimum MTU size on your LAN is related to your hardware, software, wireless interference, etc.
  • Tweaking MTU size may work well in one situation, but cause performance and connection problems in others.
  • When network devices with different MTU settings communicate, packets are fragmented to accommodate the one with the smallest MTU.
  • Windows XP sets MTU automatically, that is, it optimizes computer MTU for you. This Microsoft article explains resolving lack of connection to a broadband ISP using Windows XP: How-To Configure Broadband Connections Using PPPoE.
  • Once a network device fragments a packet, the data stays fragmented until arriving at the destination computer.
Setting MTU size is a process of trial-and-error: start with the maximum value of 1500, then reduce the size until the problem goes away. Using one of these values is likely to solve problems caused by MTU size:
  • 1500. The largest Ethernet packet size; it is also the default value. This is the typical setting for non-PPPoE, non-VPN connections. The default value for NETGEAR routers, adapters and switches.
  • 1492. The size PPPoE prefers.
  • 1472. Maximum size to use for pinging. (Bigger packets are fragmented.)
  • 1468. The size DHCP prefers.
  • 1460. Usable by AOL if you don't have large email attachments, etc.
  • 1430. The size VPN and PPTP prefer.
  • 1400. Maximum size for AOL DSL.
  • 576. Typical value to connect to dial-up ISPs.

MTU


MTU, Partial Loss of Internet Connection, and Performance MTU (Maximum Transmission Unit) is the largest packet a network device transmits. The best MTU setting for NETGEAR equipment is often just the default value. MTU is sometimes presented as something that can be easily changed to improve performance, but in practice this may cause problems. Leave MTU unchanged unless one of these situations applies: 1. You have problems connecting to your ISP or other Internet service, and their technical support (or NETGEAR's) recommends changing MTU. For example, these services may require an MTU change: * Yahoo email * MSN * AOL's DSL service 2. You use VPN, and have severe performance problems. 3. You used a program to "optimize" MTU for performance reasons, and now you have connectivity or performance problems. * An easy solution to most problems is to change MTU to 1400. * If you are willing to experiment, gradually reduce MTU as described in "Details of MTU", below. How to Change a Computer's MTU Size Note: If you change MTU on one computer, it is likely you will want to change it on your other computers, switches, and routers, as well. Instructions for changing MTU on other NETGEAR devices is found in the Reference Manuals. The third party Dr. TCP software can be used to change the MTU setting. 1. Download it from this link, choosing the zip file or the exe file at the top of the page. 2. Run the utility. 3. In the Adapter Settings pull down, select the Ethernet driver and adapter used to connect with the network. 4. In the MTU box, type the MTU size you are trying. 5. Click in any other box, without changing the data there. 6. Click Save. 7. Click Exit. 8. Restart the computer. Details About MTU A packet sent to a device larger than its MTU is broken into pieces.
