How to set priority of the internet speed?

Hello, I'm from small city of Brazil and I got a 1mbps ADSL connection (D: 120kb/s | U: 40kb/s) because it's all I can afford (I'm paying US$38 per month, monopoly :S). As the connection speed is low, I would like that you help me find a way to set the priority of the connection speed (I would like to give priority to Google Chrome and to my online games), because they don't use all the speed of my internet as I can see. When watching videos on YouTube I can see that the download speed goes to ~90kb/s then just drops to ~20kb/s causing the video to stop to buffer (when I checked that I had nothing open using bandwitdh on background). I've some programs that forces the priority of the internet (using aTube Catcher I can download the videos from YouTube at ~110kb/s, but it's unhandy to download all the videos that I want watch. I'm also using Internet Download Manager, with it I'm able to download at ~110kb/s too). I tried to use ASRock X-Fast Lan, but it didn't seem to help (or I didn't know how set it up). Is there any program that can help me? I would be really thankful if you help me :D

If this matter anyway: I got ASRock Z77 Extreme4 motherboard

With only 120KBps dl and 40KBps up you can't do much ... If you want your video to take full advantage of your connection, you have to close everything else that uses internet.

Did you read the main post with attention?
"download speed goes to ~90kb/s then just drops to ~20kb/s causing the video to stop to buffer (when I checked that I had nothing open using bandwitdh on background)"
 
More than likely you cannot fix this. It is so small bandwidth you have little space for overhead. I suspect the speed is not fluctuating it is the tool that is averaging in rates. You likely are getting packet loss because the sender tried to send more than you bandwidth, when it got a error it stopped for a tiny moment and resent the lost data. This is just how it works.

The only partial solution you would have is to get a router that has good QoS. Most have very basic stuff. The better ones allow you to hard limit traffic to some rate. Unfortunately this really only works in the SENDING side so you can only really limit your outbound traffic. They do have the ability to limit inbound traffic but it is mostly smoke and mirrors since you are dropping traffic that already used up the connection. It does work for some application so it may be worth a try. You would put a very very low limit for all traffic other than the stuff you want. You would then leave the good traffic in the high queue have all it wants. DD-WRT firmware and some of the higher end ASUS routers have this advanced QoS.

Still with so little bandwidth it is unlikely you will fix this...it is hard enough when you have many meg/sec of data to get the QoS to have any effect.

I've upgraded my internet speed, I have now 625kb/s download and 40kb/s upload (WOW so incredible
;) ), but I didn't give up about set the priority of the internet speed. I've been searching for a router with QoS as you said, and I've found Asus RT-N10+ C1 for a good price and it caught my attention, but I noticied that it's a router (I still need a modem), then I tried to find a modem router and I've found Asus DSL-N10, but it's X2.5 more expensive :(

So here is my new doubt: What's worth it? Buying Asus RT-N10 + C1 and use with my ZTE ZXDSL 831 Series (my modem atm) or wait more time saving money and buy Asus DSL-N10?
 
I would change your current device to run ONLY as a modem and disable the router part and use your new router as the router. A modem is a very simplistic device so it is unlikely buying a different one will make any difference. It is generally better to keep the modem and the router separate since it greatly limits you selection of routers if it must also contain a modem.

Ok, I'll buy the Asus RT-N10 + C1 and use it with my ZTE ZXDSL 831 Series, [strike]but how can I make the ZTE run only as a modem?[/strike]

[strike]Also, I got a little problem that I need know if it's related to my modem: Sometimes my ping on far away servers (Europe mostly [I'm from Brazil, South America]) go up to 350~400 (when normaly it's 270~300) and then I have to restart my modem, doing so will make my ping go down again, is that a problem caused by my modem?[/strike]

So, I'm definitely getting the Asus RT-N10+ C1 router, but I want know if it's possible to limit the LAN speed. I'm using 2 PCs, I want let PC 1 be able to reach all the bandwidth (5mbps) and PC 2 able to reach only 2mbps, is it possible?
 
Wish I could be somewhat helpful but maybe you should call their toll free number and get them to explain how their QoS really works. They make a big point of saying this devices is "manual free". So you can just click on the buttons that say do magic QoS things and it will all work. I normally like Asus routers but this one has me doubting this company. What a bunch of garbage you have to actually have the device before you can see how it works.

Can lan speed limitation be done like you want...sure.. Can this device do it I suspect it can not mostly because this is not a feature you find on consumer routers. Most consumer routers can only limit the lan-wan traffic. Then most can only limit the upload traffic. Many of the other asus routers do have the ability to limit the download traffic to fixed amounts. No way to tell if this one does with no manual. Even so this feature only works for certain type of traffic even on the routers that do have the feature. If the application you are running does not slow down in response to errors then it will have no effect. These type application (like bit torrent) can only be limited from the ISP side.

Damn, I'll have to try anyway
About QoS thingy, would it help me with ping jitter? Because when I'm playing and an other person is using the other PC, my jitter is really big (like 300ms sometimes)
