Banana Pi BPI-R3 OpenWRT image

That easy? Do you recommend that module MT7921k? There are plenty on aliexpress. Would WED work?

josh9 · November 17, 2022, 12:16pm

I bought those el’cheapo: https://pl.aliexpress.com/item/1005004545962352.html?spm=a2g0o.order_list.0.0.5d021c24DkN4GJ&gatewayAdapt=glo2pol.

They are detected by BPI-R3 with 2.5Gbps. Work fine with 1Gbps, will test soon if they achieve the 2.5Gbps.

Tested. Other end with I225-V v3:

Only wonder about high retransmitts,do you have flow control enabled on the remote side?

Hi dangowrt!

Would you mind summing up the hardware you have tested with, including which 3G/4G/5G card you used? That is the last part of my shopping list

How much work is it to get the SIM working with vanilla OpenWrt snapshot? Are there instructions anywhere?

Banana Pi R3 (you seem to be running revision 1.0)
2x TP-LINK TL-SM410U for 2.5 Gb/s (?) ethernet
MT7921K, AMD RZ608 variant
M.2 Key M to key A+E converter (seller hebeda at eBay for this and the AMD card?)

Thanks for your awesome work getting vanilla OpenWrt supported for this device!

dangowrt · November 19, 2022, 12:32am

Any mPCIe module should work. I tried with Quectel EC-25 and Sierra Wireless EM8455 in NGFF->mPCIe adapter. Due to limitation of the mPCIe socket, only up to USB 2.0 speeds are supported, ie. it doesn’t make much sense to buy faster modems because the speed will anyway be limited to ~ 200MBit/s. If you want faster (LTE Cat.12 or 5G) modem, you have to connect it via USB 3.0 or PCIe, both aren’t supported on the mPCIe slot of the R3 (which is USB2.0 + SIM only).

The SIM slot is hard-wired to the modem and doesn’t need anything special to work with OpenWrt. Just install luci-proto-qmi (recommended) or even luci-proto-modemmanager and things work out-of-the-box.

There are generic instructions which work fine also on the R3, details may differ depending on the modem you choose: https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle

You can also use slightly cheaper ONTi SFP modules which then also support fall-back to 100M/1G speed (SM410U supports 2.5G only): https://www.aliexpress.com/item/1005004545962352.html

If you are inside the EU, ebay seller hebeda is probably the fastest and safest option. But you can just as well pick a suitable module on AliExpress. The best option is actually to wait for MT7916+MT7976 WiFi 6E modules to be available (because that will be 4T4R and support the hardware offloading features of MT7986 SoC)

hi every morning i have one question when i set openwrt and click save & apply button then use openwrt luci`s reboot it is recovery to not set openwrt how can i fix this bug? or operational problems?

vladi2010 · November 19, 2022, 9:12pm

Hello everyone, my name is Andreas and I am a total newbie.

I installed the SD image after that I set something wrong in OpenWrt.

Since then I don’t have a static IP address and I don’t get an address from my router (Fritz!Box) either.

I can’t think of it anymore on Openwrt.

How can I reset the device? the reset button doesn’t seem to work.

thank you for your help

Andrew

@dangowrt

After commit 9b482ee22f3f509880d2420652392971eef3211d (kernel: add more fixes for mtk_eth_soc), bridge is not working.

config device
	option name 'bridge0'
	option type 'bridge'
	list ports 'lan1'
	list ports 'lan2'
	list ports 'lan3'
	list ports 'lan4'

	option proto 'static'
	option ipaddr '192.168.1.1'
	option netmask '255.255.255.0'
	option zone 'lan'

I can ping 192.168.1.1, but DHCP is not working and I can´t connect using SSH or HTTPS…

Started to receive these messages too:

This commit includes different patches

https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=9b482ee22f3f509880d2420652392971eef

Could you try to figure out which one breaks functionality (removing patches one-by-one)?

synlab · November 22, 2022, 3:57pm

If I remove 732-14-net-ethernet-mtk_eth_soc-drop-generic-vlan-rx-offloa.patch it works again. I will let the system run for some time to check if the messages are gone…

frank-w · November 22, 2022, 4:28pm

Ok then you could send felix a message for next steps maybe cc the openwrt mailinglist.

It looks like the patch was not sent to mtk mailinglist to be upstreamed to mainline linux. So it is an issue only in openwrt.

DGinUK · November 23, 2022, 9:26pm

Hi

have you been able to get the MT7921K to work? i have the same card, with adapter and im running OpenWrt SNAPSHOT, r21335-e410833bdd but cannot see firmware or drivers anywhere?

if i try and install kmod-mt7921e it says my kernel is not compatible, same for architecture

many thanks

dangowrt · November 23, 2022, 10:54pm

You have to update to most recent snapshot first. You can either download it from downloads.openwrt.org or use one of the semi-auto updater clients like luci-app-attendedsysupgrade or auc. Try this:

opkg update
opkg install auc
auc

That should fast-forward you the most recent snapshot and subsequently allow to install kernel packages like kmod-mt7921e.

lu_zero · November 24, 2022, 3:47pm

I add another question regarding the wireless, what is the process to have it have a different mac address? It seems to be always 86:0c:43:26:60:00

frank-w · November 24, 2022, 5:04pm

you can set mac in interfaces file,via udev or systemd (if openwrt use it)

DGinUK · November 24, 2022, 5:11pm

@dangowrt many thanks, Have updated the Kernal and now having a look at the packages again.

amazing, after installing package and a reboot i can see the card…time to play some more

dangowrt · November 24, 2022, 5:12pm

I’ve added support for randomly generated persistent MAC addresses for wlan interfaces based on the Ethernet MAC address in

lyh2000free · November 28, 2022, 11:25am

Hi

I noticed a wireless module using mini-PCIe interface, which seems to use the combination of MT7916AN+MT7976DN. If possible, can I trouble you to see if this module is compatible with BPI-R3.

Of course, it would be even better if Banana Pi officially launched an M.2 M-Key module that does not require an adapter board.

shotsix · November 29, 2022, 5:35pm

I have one of these in my BPI-R3 via a M.2 adapter and it works just fine. You’ll end up with 2 2G radios but can always disable one.

terryeh · November 30, 2022, 9:08pm

I can see you used the MT7921K, but that’s not 6E either ? (6ghz) Banana Pi has miss informed a lot of people by stating that it is 6E (6ghz) and it is not. As you pointed out. And I see no correction on this ! Which is leading to perpetual confusion. You are also correct in pointing out that the correct chip from Mediatek is the same die and could be put on the board. IT Could be 5 & 6 ghz by leaving the 2.4 ghz off the board (not a lot to be gained in WiFi 6 with 2.4) Just stick in a 2.4 USB dongle, if you need 2.4 I have considered removing the 2.4 and soldering on the 6 ghz myself. Or how about a “group buy” of such a board. I wonder how many boards we would have to buy, to get what we thought we were getting. 4x4 5ghz + 4x4 6ghz The only reason I was attracted to this board in the first place.

Just another WiFi guy eh!
