QoS Packet Scheduler – What Does QoS Packet Scheduler Do and Why Keep It Enabled?

qoswindows xp

I know what is QoS and don't need general explanations of the term and opinions on what is "QoS packet scheduler" based just on its name. What I am looking for is information on what exactly does Windows "QoS packet scheduler" affect (I suspect it does nothing useful unless there is at least router-side support for its function). Do you happen to know?

Try this Microsoft KB on Windows XP Quality of Service (QoS) enhancements and behavior.
and this SevenForums discussion referring it.

From a recent article,

20% of your bandwidth is reserved only when QoS tasks are running. When no QoS task is running, by default you have access to 100% of your bandwidth. So by going forward with removing the 20% reserve, essentially you wouldn't be recovering all 20% of your bandwidth; you would be recovering the piece of the 20% that is wasted and unused when a QoS task is running.

All this basically says, you are on the right track not worrying about its effects.

Windows – How to connect the XP laptop to the wireless network if the wireless network doesn’t show up in the list

You say that the laptop is Windows XP, this can be up to/around 10 years old.

My guess would be that the wireless network is being broadcast in a band or mode (a/b/g/n) that the wireless card in your laptop does not understand.

If however it does understand, my best bet and advised solution would be to manually assign/setup the profile and see if it will connect as sometimes this can work.

Go to the list of preferred networks (Network connections, right click wireless, go to the wireless networks tab), and type the details.
