Internet Priority? QoS?

post #1 of 5
Thread Starter 
Hey guys, so recently internet became really spotty for one of my housemates on a router i got (DIR-645, first time in two weeks its been spotty) so he had been messing with some of the router settings and noticed he had turned on the QoS engine today.

The router is set to protocol priority which sets a priority scale like this : 1 is the highest where 4 is the lowest.

It currently has set 16 different tasks such as Youtube and DHCP which are set at a priorty level of 2, Where i noticed that theres one ip address set to priority 1. redface.gif

Just wondering if this would make a difference?

Any help would be greatly appreciated ! biggrin.gif

Kinda-sorta. As far as I know the top priority more or less has dibs to the pool first.


This is how I believe QoS work:
It's like when you go wait in line at boxing day and there are hoarders waiting at the front and there's only 1 item.

If I were setting it up, I'd give priority to the following order 0-9 (0 being higher)
0 - DHCP//any required services
1 - (nothing as a buffer)
2 - HTML
3 - MSN or other IMs Skype etc...
4 - (nothign as a buffer)
5 - Gaming applications
6 - Media aka youtube etc

I have 1 and 4 for applications I forget of and 1 as a test.

If it's by percentage I'd allow at least 20% for basic web surfing and 80% for media/gaming assuming your internet speed is relatively fast I'd go down to 10-15%.

When 1 IP is given top priority he basically just made it so that. that one IP can hog all the internet if and when it so pleases.

NOTE: this is my interpretation of QoS in basic routers.

ah thanks for the reply, so its kinda like a line queue, where top priority has sorta .. a skip the line pass? Sorry, not super experienced with networking

Also would the amount of clients (users/computers) effect the wireless speed? Originally we had 4-5 clients on one router and 4-5 on another router (in the same household. Connection consistency and speed were good. As of yesterday we put all clients on one router (8-11, averaging around 9 at a time) and connection speed seemed to have dropped pretty bad, One of my computers cant really connect to the web anymore and keeps timing out. redface.gif

I would like to go back to the 2 router set up (one for top floor and one for bottom) as i would think it would ease the load, since all 4 of us stream video (and 2 do alot of downloads/torrents) but the housemate is pretty insistant on having one since its working fine for him now. frown.gif

For every wireless connection that is added, your throughput speed will be cut in half. Please note 802.11 G throughput speed will max out around 24 mbits... The reason for this is wireless is half duplex. It is just like taking 9 walkie talkies, and everyone trying to talk at once. This also does not take into the consideration clients that have slow connection rates already slowing down the cell. The torrents are going to kill your wireless connection speed for all the clients unless you throttle them.

The best thing for you to do is to add another access point, and move the torrent machines to wired connections if all possible.

No.... you want to give time-sensitive applications higher priority. A momentary pause in unbuffered data like game or voice is disruptive and noticable. A momentary pause in loading a webpage is not really noticable.

Also be aware that QoS adds CPU overhead so hopefully your router can handle it.
Once again...
