| A question about where to setup QoS On Sunday, I received an incoming call while I was watching a HD movie online. I had no problems to hear the other end. But the other end could only heard couple word here, there, not the entire conversation. I had no any problems if I didn't watch the movie.
I believe I should do the QoS. Here is my setup:
DSL modem -> Linksys WRT54GS -> Linksys PAP2-NA, as you can see the phone adapter is behind my router. Both the router and phone adapter support QoS. My questions is that; where I should setup the QoS?
1) on the router
2) on the phone adapter
3) on both
Thanks. |

As Mazillo suggested, the correct place to set up QoS is on the router.
I was tinkering with the QoS settings in Tomato today. The way it works is you first define classes. I defined a class for VoIP. I wanted it port-based, so I added port 5060. But, I also had to enter in a range of RTP ports - check the SIP tab on your PAP2 to find what these are.
Once I had the class set up, it was just a matter of allocating bandwidth to each class. Keeping in mind that G.711 uses about 90 kilobits per second in each direction, it was relatively simple.
To check and see if I did it right, there is an option in the Tomato menu called "View details". Here, you can see all the current connections from your network, and what classification they are. I made a VoIP call and confirmed that the classification on the details page matched the classification I had set up earlier.
Even if you're not using Tomato, the procedure will likely be similar.
Good luck!

I have the same router that you are using and I currently do not have QoS enabled. Even when I am downloading or watching streaming video, my calls are still fine.
The only time that I have had my callers unable to hear me is when I am uploading large files while talking on the phone. I have tried to enable QoS, but my callers still got choppy audio when I was uploading large files.
I want to try an put Tomato or DDWRT firmware on my router, but I am afraid that I will brick it (this is what happened to my old router during a firmware upgrade). |

What is the brand/model of your old router that got bricked? If you had a serial console cable, chances are you can recover this device. |

BTW, usually older (earlier version) router has more Flash/RAM capacity to run open-source firmware to host some applications.

| said by mazilo:BTW, usually older (earlier version) router has more Flash/RAM capacity to run open-source firmware to host some applications. Yes, I know. I looked into the available RAM and Flash memory before buying my router. When I saw $22.99 for my router, I just could not pass that up and could not justify spending double or triple that amount on something that had more memory (and was still only 802.11g and only 100 Mb ethernet).
I just needed something to get me by until I could find a good 802.11n router with gigabit ethernet. I am waiting until they update the routers with the finalized standard of 802.11n and not the draft. |

Wow! Thank you guys for the info.
Since you guys started talking about firmware. My WRT54GS's Firmware is Version: v7.50.2. I went to DDWRT web site and couldn't find a higher version than v7.50.2.
Does anyone know a better one?
Thanks again. |

I went to DDWRT web site and couldn't find a higher version than v7.50.2. DD-WRT is not Linksys!

| Yes. I bought the original one from Amazon with the firmware v7.20.2. It is Linksys firmware.
Which means I don't need to upgrade, right?
Thanks. |

BTW, what is the version number of your Linksys WRT54GS router?

| I don't want and don't need either unless it is necessary. I typed wrong version # in previous post.
Ok. let me clarify, the Linksys WRT54GS comes with the version v7.50.2 firmware (not v7.20.2) installed. It is original one.
Thanks. |

Can you telnet and/or login to your WRT54GS? If so, once login into the shell, can you try either df and/or free to find out the partitions and RAM sizes, respectively? I suspect this device has a built-in Flash/RAM of 2/8MB only.
