2 Gbps WAN/LAN NAT Routing on ramips MT7621 devices

Gingernut · 2022-10-12T06:15:49.077Z

Getting these errors now and again running builds from latest master on a Xiaomi R4G used as a simple dumb AP hooked to main gateway over ethernet.

That’s an mt76 Wi-Fi driver crash

arinc9 · 2022-10-12T08:27:20.600Z

arinc9:

vevere:

badulesia:

something simple like this (forget about the colors, I picked up what I can to mimic)

enable offloading : software hardware

SW/HW radios being disabled if the checkbox is not checked.
SW selected as default.

or something similar to the other choices on this same FW page, a drop list:

image612×204 4.87 KB

Texte: Flow offloading

choice 1: Off/disable/No thanks ...

choice 2: Software

choice 3: Hardware

I don't think we can preserve the section ids, flow_offloading and flow_offloading_hw this way, which would break compatibility with old uci configurations and break more things. I've made a small fix with a friend which hides the other option when one is selected.

My change won't be accepted because it contradicts with the implementation on firewall3 and firewall4. The current way on LuCI cannot be changed because of this. Check @jow's reply on the pull request.

badulesia · 2022-10-12T10:04:25.072Z

Hi.
It's just a proposal to render better. How often will someone change this setting ? Just a couple of time, so it's not that bad.

netRAT · 2022-10-17T13:30:02.598Z

I'd really like to try your build on my Xiaomi Redmi 2100 but the page linked in the topic seems to have been cleared off of those images and according to my understanding only recent snapshot images are baked in with the patch.
Is it possible to grab a non snapshot image from somewhere?
Doesn't have to be the latest official version...
I kinda know my way around customising and compiling my own images but integrating patches is beyond my current skillset... Not for the lack of tryng though...
I just couldn't find a resource that describes the process using terminology that I could wrap my head around...
Cheers.

arinc9 · 2022-10-17T13:56:20.679Z

Currently, the easiest way is to get a snapshot image from the firmware selector. Anything else, you're on your own.

ProjectThreepio · 2022-10-19T04:16:55.075Z

Not sure how the trunk/branch/release cycle happens here. If recent snapshot images have your patches, does that also mean that the just-released 22.03.1 and 21.02.4 releases also have them, or that some future official stable release will have them?

maurer · 2022-10-19T07:12:25.176Z

only future stable releases - 21.02 and 22.03 don't do backports of such advanced features

TheCrypt0 · 2022-10-23T10:11:42.536Z

I'm sure this is an obvious question (not really used to technical terms), there's no way the EdgeRouter X SFP can benefit from this patch?

d687r02j8g · 2022-10-23T10:22:51.737Z

In the first post under devices that can't benefit it says

RGMII2 pins are used with an external phy on these:

mt7621_ubnt_edgerouter-x-sfp.dts

arinc9 · 2022-10-23T22:31:02.624Z

The comment you replied to already explains this but it'd be great if you could also confirm the same behaviour I was getting on my EdgeRouter X SFP. I don't have access to the device anymore and need someone else to do a few tests on it along with this.

VA1DER · 2022-10-25T13:06:24.554Z

Does this change affect the Netgear R6700v2?

arinc9 · 2022-10-25T16:41:34.193Z

Yes, it is applied to this device as well.

kefwrt · 2022-10-30T23:59:12.043Z

Hello arinc9, and thank you for the work. As an amateur on OpenWRT installation, the real easy way to have this feature "soon" will be to wait for the official stable branch release ? I want to try it on my Cudy W1300 but it seems quite a ride to apply the patch.

arinc9 · 2022-10-31T05:34:21.546Z

I already answered this above.

kefwrt · 2022-10-31T12:00:49.106Z

Yes i've seen this, but it seems flashing the router with a snapshot firmware can be tricky for non pro users (no LuCi, risks of things not working, bugs etc...). So that's why i was wondering about the safest way possible.

Annick · 2022-10-31T12:42:23.608Z

as i bridge lan1 lan2 & wan is it of interest ?

arinc9 · 2022-10-31T13:00:58.598Z

There are no different steps to flash snapshot image compared to stable releases. You can request a snapshot image with Luci included from the firmware selector. Snapshot images are not that unstable, compared to stable releases.

arinc9 · 2022-10-31T13:02:03.586Z

Please read the other posts in this thread which mentions this.

kefwrt · 2022-11-01T22:03:16.371Z

Ok thank you for the advice, just made it with the last snapshot, and the result is :

I'm still around 500mb on download for a 1gb connection, with or without the Software/hardware flow offloading on my Cudy WR1300 (v1 with USB port)

Results coming for iperf3 directly from the router, and same results on computer and server on Speedtest and Nperf.

Even if the speed is still not ok i can notice a way better stability on the connection during the tests and downloads.

I had no problems to have at least 800mb on OpenWRT 19 few months ago, it dropped at 450 with the 20, was back at 800 with the flow offloading activate, but made the connection very unstable.
