I'm assuming you just want to make it so people watching netflix or whatever doesn't make your computer lag, so you put in what your max upload and download speeds are in the bandwidth boxes and I'd probably just set the qos by mac address rather than dealing with ports so your computer's traffic just gets prioritized

You can look up how to find a device's mac address, just set the device's priority in the rule list and then lower down you set what % of the bandwidth you want each device/class to get

tf2 are TCP/UDP ports 1200 and 27000-27040
so give those priority (set them to highest)

mumble is 3312
do the same

you could also give your computer priority over other devices (phone/laptop)

I used these three sites

Okie dokie I'll try it out. Sounds pretty straight forward and those links were good reads

thanks grillz

What do you do if you only have these options? :<

you install custom firmware

Any recommendations?

DD-WRT seems to be pretty popular.

TF2 ports.
TCP: 27000:27050 (You can expand the range if you feel like it. sometimes I've seen servers with higher ports such as 27135, though normally that is not the case)
UDP: 1200,2478:4380,27000:27050

Use your IP (internal)/MAC for source, leave transferred blank (both), and highest.

Mumble port should the port of the server your are connecting to. For example, the default port of mumble is 64738.

Got some info from here and adjusted it a bit:
https://github.com/rrelmy/asus-rt-n56u-firmware/blob/master/src/router/www/ajax_qos_default.asp

This conflicts with some of what grillz said. Is the port the server uses (at the end of a connect line) the same port I need to prioritize on my router, or are these different things? And same thing for mumble, what is the port 3312 grillz mentioned? Is that incorrect or do I need that AND the port of the server I'm connected to?

This is really important, my internet sucks. I get lag spikes if somebody else loads a bandwidth heavy page, let alone tries to stream anything

It's a range of ports, and yes it's the same port at the end of the server address.

you need to see what your router is compatible with, tomato and DD-WRT are both of the popular and easy to figure out firmwares, I think tomato's qos is better though if I recall correctly

dd-wrt, openwrt, and tomato are the popular ones. I don't know if all three are gonna be compatible with your router since afaik it isn't very widely used.

also just a warning, a lot of routers have shitty qos/customization, if that's the case for yours, check to see if it's compatible with custom firmware and use that instead. Firmware can help a lot with wireless connections, as well as with QOS shit and even ping problems

Use the port the server uses (which you are connecting to). The range of ports I gave you for TF2 is possibly a 'more complete' set from what is linked above in grillz post. The 3312 comes from the the linksys link where the person says he wants to connect to a mumble server with a port of 3312. Use the port of the mumble server you are connecting to (default mumble port which I listed is 64738).

* Open regedit
* Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
* There will be an entry for network performance throttling, default value is 10; set it to FFFFFFFF hex (willl look like 0xFFFFFFFF to the right of the entry)
* Reboot

I hope this helps.

Well I installed DD-WRT and it's working, but it seems a little wonky. If I disable wireless SSID broadcasting, I lose internet connection even though this computer is connected via cable. :<

Edit: Actually, I lose internet connection and have to unplug both the router and the modem to get it back when I change any option.

I finally got around to setting up my new router (Asus RT-n66U) and it is working fine. Except I can't connect to steam community and get booted from servers because I can't connect to VAC or whatever. I've disabled my routers firewall and put all of the tf2/steam ports into portforwarding, but no luck.

Please help, I have a match at 11 tonight

Should also note that I have UPNP enabled.

I got it to work by launching steam with the -tcp launch option.

I was playing fine and then my ping spiked from 60 to ~160. It was high for like a minute, varying rapidly between ~140-200 during that time, and then went back to normal. This is uncharacteristic of my ISP, normally the only time I spike is when somebody else is using the bandwidth, but nobody else was on the internet. Could this be a router problem (if so, what settings I should change)
