Hi,
I'm trying to prioritize my TV using QOS on my R7800, latest build (53445).

My TV is connected to port 1, port 1 is set to Premium by default.
I also set mac priority for my TV to Maximum.

Is my TV now Premium or Maximum ?

Please see attached image for my QOS current settings.

Thanks

Assuming that Port 2,3 and 4 are set to Maximum.

It's an old saying. One learns to walk before running.

Then, if really an excellent runner, maybe training for the Olympics.

There is no shortcut for bettering oneself, i am afraid. Cool

Thanks, I swear Google was referring me to different QOS tutorial on DD-WRT.

So, MAC priority comes first.

Anyway, please let me ask two more questions. I tried to find the answer in the tutorial, but I couldn't.

1- When we say that the Ethernet port priority is set to Premium, does that apply to the access point that is connected to one of the ports?

2- I don't want any device that is connected to an Ethernet port to get more bandwidth than the phones that are connected to the Wi-Fi. From what I read, other devices that are not prioritized are set to "Standard" by default. So, to get what I seek, should I just set the port priorities to "Standard" instead of "Premium" so that they will be equal to my phone?

Sorry if the questions are lame. My specialty is far from networking and computers.

Say someone wants to find out something specific about UK, it would be more sensible to ask an English. Not just anybody who may or may not know.

Likewise, a question about QoS settings on DDWRT router would have 'QoS' and 'DDWRT' together in a phrase in a Google search like:

How to configure QoS on DDWRT router?

Here is another article from the same search:

https://blog.flashrouters.com/2015/03/05/setup-qos-in-dd-wrt/

You may find the answers to your questions in there.

I'd like show my students how to fish. Rather than giving them fish. That's way they become really good at solving their own issues in no time. Cool

I know that and I did it but was referred to another tutorial.

Anyway, if anybody can answer my two questions it would be much appreciated. Couldn't find the answer online.

Thanks

maybe the questions are irrelevant? because somehow the commit tells me that port priority is not supported on the router

Hmm. I was not aware that QoS on Ports not working as alerted by ho1Aetoo since I happened to use only MAC and IP (i.e. Netmask) QoS settings; With one Interface setting to limit Cool Guest network bandwidth.

But since you want priority for a few specific devices, it'd be much simpler to use their MAC, or (fixed) IP addresses for QoS.

As for what priority and level settings, you need to find out how much bandwidth each specific device needs to operate without 'stuttering'. For example, nominally Netflix Full HD (1080p) stream needs some 5mbps; a VoIP phone needs 100kbps. It's certainly beneficial if your DOWNLOAD bandwidth more than covers at least your priority devices when in use CONCURRENTLY. If not, stuttering may occur regardless of QoS settings. Keep in mind (using an analogy) water does not fill your kitchen sink quicker than its maximum flow rate can deliver (i.e. from the street into the home).

I only set maximum setting for my SECONDARY router that has other devices behind it on a separate network and some also needs QoS.

Note: only one priority setting (MAC or IP) is needed for each specific device. Overlapping is unnecessary. It simply makes the DDWRT router work harder for no reason. Lastly, Flashrouters (earlier link) gives some hints on HFC or HSFC settings. Good luck.

The tutorial says: "NOTE: Ethernet Port Priority only works on old 802.11g only models with ADMtek switch chips. If you don't have ethernet port priority listed, your router does not support it."

I was confused because I have Ethernet ports priority listed in my R7800 QOS gui.

I already used MAC priority for my two TVs and other devices I need.
Let me describe a scenario so my inquiry become easy to understand:

I have R7800 main router.
And Rax40 Router is connected to the Ethernet port 1 of the R7800 as a wireless access point, with priority for the Ethernet port 1 is set to Maximum.

Phone 1 is connected to the R7800 wifi, no QOS priority is set for Phone 1.
Phone 2 is connected to Rax40 wifi, no priority is set for Phone 2.

Now, I think Phone 1 priority is set to standard by default, right ?
What about Phone 2, is it now prioritized over Phone 1 because Ethernet port 1 priority for the Rax40 is set to Maximum ?

How can I make Phone 1 and 2 both equal in bandwidth? By setting the Ethernet port 1 priority to Standard?


Thank you.

Anyway, as ho1Aetoo referred that the Ethernet ports priority doesn't work on R7800, then my inquiry is now just for extra knowledge.

Thank you.

Ordinary android mobile phones.

I gave the example of these Two phones to make my inquiry clear, because I actually have the main router in my room upstairs, and the access point for my family downstairs.

And I don't want my family devices to be prioritized by the Ethernet port priority that is set to premium by default DD-WRT settings.

OK.

BTW, QoS on Port is not operational unless a Max Rate (other than Disable) is selected on the right. The way I read it.

It would make no sense otherwise.
