Raspberry Pi 4 Official - Slow WAN

LordPhoenix · September 17, 2021, 6:26am

Hey Guys.

Finally took the plunge and converted one of my Pis to a OpenWRT Router.

I’ve got an USB3 - USB to Ethernet based on a Realtek Chipset for WAN. And Built in Ethernet for LAN.

It’s all working well but the performance of the WAN is around 220-240 Mb/s vs 940+- Mb/s if I hit the ISP ONT directly and bypass the Pi

I know the pi4 is more than capable of gigabit Ethernet. Can one one provide some guidance. I suspect the old driver that ships for the Realtek chipset is to blame since it only seems to connect at 480mbs(USB2.0) but the actual device is on the USB 3.0 hub. And is a USB 3.0 device. Was tested prior on other OSs.

Here's some output from OpenWRT

What bugs me, is the USB 2.0 Hub connection, even though its on a USB 3 Port on the Pi, and the Device itself is definitely a USB 3.0 Device,

I see there is a far more recent driver available for the chipset, but I'm not too sure how to go about patching or compiling it for the Pi

You have newer version than I have. Could you give it a try and test with wulfy's image?

anon50098793 · September 17, 2021, 9:08am

looks like a faulty or poorly detected hub/cable or something... ( brand? model? )

Already tried his awesome image, but still the same, could the chipset be 1gbps capable, and the branding and everything say USB3, but the Hub is actually 2.0? Aka Chinese knockoff?

anon50098793 · September 17, 2021, 10:46am

try without the hub... ( nic direct to the blue usb3.0 ports or an alternative hub )

LordPhoenix · September 17, 2021, 10:52am

Hi Wulfy

The device doesn't have a hub? it just plugs straight into the Blue PI ports?

As an alternative, we have the following available in my country that I can potentially get

The TP-Link U300 and the ORICO UTJ-U3 - just not sure what is supported nicely by OpenWRT and also what would handle GB wan.

anon50098793 · September 17, 2021, 10:53am

??? you've mentioned a hub 2 or 3 times...

LordPhoenix · September 17, 2021, 10:55am

Sorry - I meant to say - based on the stats from Linux, its connecting on the USB 2.0 Controller, not HUB My bad.

anon50098793 · September 17, 2021, 10:56am

but you say it works as usb 3.0 in a normal PC right? (are you 100% sure?)

tag cloud (shame dude deleted half his posts)

LordPhoenix · September 17, 2021, 10:57am

Thats the thing, I'm pretty sure when I bought this, which was about a year ago, it was working - But to be honest I don't recall checking that it connects over the USB 3.0 controllers,

What I see now - plugging it into my Mac - the System Report shows Max Speed - 480mb... So I'm guessing I was taken for a ride and bought a USB2.0 device even though the colours and the branding and product page said 3.0?

Hence me now asking about the TP-Link U300 and the ORICO UTJ-U3 - just not sure what is supported nicely by OpenWRT and also what would handle GB wan.

LordPhoenix · September 17, 2021, 11:06am

Our local provider has the Orico in stock, - the TP link would have to be ordered, so I'm not sure which one will work properly, can you @anon50098793 - Maybe advise?

anon50098793 · September 17, 2021, 11:08am

appears to be asix... go with the tp-link it's a known entity... (or wait to see if anyone here is running the orico)

there is nothing 'wrong' with asix (actually for non-openwrt use it has some advantages)... but over 600mb/s many users have reported better performance with rtl8153 chips... and they generally run cooler

Appreciate your time - Thank you. Will do so.
