thx for your help, appreciate it.
i tried that but no solution found...i ended up returning it.
This one seems to be working (detected at least): https://www.amazon.fr/dp/B07BRM4R59
i am waiting for my other coming from aliexpress to see if i stick to that one or not. 
I see some regress in last kernel numbers in detecting sfp gear... 1gig and gpon 1/2.5gig ... Even avago 10gb mm sr not want to work with bpi r4 or my zyxel xgs1010-12 with openwrt, same module in ofw works like a charm.
I have issues with the BE14-WIFI card (MediaTek MT7996E).
When setting up the 6GHz-SSIDs to band 53 (frequency 6215 MHz), I constantly get the following warning flooding my syslog:
Thu May 1 11:13:34 2025 daemon.warn dawn: frequency 6215 is beyond the last known band. Using '802_11a' band parameters.

Devices connect without any issue though 
Dawn documentation seems to imply configuration support for 2.4g and 5g, so the part of UNI5 mentioned in the error logs (6215Mhz) might be unknown to it.

Hi all,
What is the status of the BPi R4, is it fully supported? Any bugs left? I want to replace my R4S router, and connect via 10 GB SPF+ to the XGS 1250-12 (running stock).
Secondly any advice on which SPF+ to take?
Thank you,
Ramon
dac cable, lower power, lower heat.

better if you can use them, but they're also limited range compared to fiber runs.

Ok sounds like two good reasons. Any brand or type to use or avoid?
I just need like 2-3 meters. Nothing too excessive.
But the BPi itself is fully up and running?
Thank you!
Might be different with the R4's phy, but I've had no issues with just the cheapest ones I could find. Using them on Intel NICs in the server, Zyxel and no-name switches. I watch for sales on amazon and when I see a 3 meter one drop to like $10 I grab one for spares.

Cheap DAC from AliExpress (opt focus or some such) works fine for me (only needed 0.5m tho)

The BPI-R4 board itself is rock stable in my eyes, I am using DACs as well as OM3-cabling and only deployed the variant with 2xSFP+ in my setup.
The BE14000 still has some issues. For me it is lower range (compared to 4x4 AW7915-NP1) and some issues with WIFI roaming (but those are normally client issues), Iwill try to workaround with setting 802.11r.
I installed and operate that far
- 1 wired router (2 mPCIe WIFI-cards)
- 2 dump access points
- 1 with 3 mPCIe WIFI-cards)
- 1 with BE14000
- 1 4G/5G-router (currently testing cards, the router itself behaves completely as expected)
I will deploy three more access points for serving a bigger outdoor area.

i would say depends if you target to use wifi/sim card or not. i can still see lot of people not happy about the wifi board range coming with it and heat dissipation that comes with it.
Also, they seems to be ready to release even more variant like 2.5g port instead of 1gb...which you may consider if you have appetite for it or at least it should lower down price of the first iteration.

Yeah I heard about the wifi issues. I currently have 2x R7800 as APs and a R4S as router. So I guess im just going to get the Bpi R4 without Wifi for now. Maybe get a better RF Wifi 7 AP in the future. For now I just want to get my router upgraded that I can get things like my 10 gbit NAS available for all VLANs.
Two more Bpi-R4 APs?
You mean that the switch has all 2.5 gb ports in addition to the 2x 10gb? that may be useful. Any idea on the timing and price delta?
yup. it should be called r4 pro. you can find info on the banana forum that i linked above.
no idea for price or timing

All devices I named are BPi-R4 (1×router + 6×APs as final expansion stage; in a distant allotment garden 1×5G-router).
The remaining ones are not yet deployed, because I was not yet able to lay the cables to the outer part of my property.
They have really low basic consumption, cabling via DAC/OM3 has very low consumption, the system itself runs rock stable, they are cheap. WiFi with standard AX-cards (AW7915-BPM, AW7916-NPD) is utmost stable.
Yes, BE14000 has issues, but those will eventually get solved. Instead you can buy other cards (as mentioned above) for the beginning. I myself anyways do not see reasons for deploying WiFi 7 now, as I do not have a single device really capable of using it and as it doesn't have real world benefits over WiFi 6 (all 3 frequencies covered with e.g. 1×AW7915-NP1+1×AW7916-NPD).

Apparently there is an engineering sample already.

the R4 is weaker CPU than R4S though, right? but better ports.
its kind of different. The R4 has 4x A73 and the R4S 2x A72+4xA53. But I think the R4 has better NAT HW offloading etc. So as long as the R4 can get "close" to doing the 10Gbit NAT then it should be good enough for me.
u know what, i think i'm mixing up relative performance with R6s, because that's the alternative i was considering. but actually my meagre upstream can't really tax any of these atm.
