A new dual 10G router based on Filogic 880 (Banana Pi BPi-R4)

Finally I have few minutes to find a working workaround to make the wole VoWifi connection establish better.

tl;dr solution:
SW offload + QoSify (not SQM script - with SQM script or pure SW offload it takes 2 min to establish).

If someone have same issue for VoWifi / Wificalling, here are my Qosify configs:

# /etc/config/qosify
(...)
config interface wan
        option name wan
        option disabled 0
        option bandwidth_up 1000mbit
        option bandwidth_down 1000mbit
        option overhead_type none
        option ingress 1
        option egress 1
        option mode diffserv4
        option nat 1
        option host_isolate 1
        option autorate_ingress 0
        option ingress_options "nat diffserv4 overhead 44 mpu 84 wash"
        option egress_options "nat diffserv4 overhead 44 mpu 84 wash"
        option options ""

## /etc/qosify/00-defaults.conf
(...)
udp:500         voice
udp:4500        voice
udp:5060        voice
udp:5061        voice
tcp:5060        voice
tcp:5061        voice

Why besteffort? Besteffort is set to CS0 so it is not getting prioritized.

I have set telephony (EF) for vowifi udp 500 and 4500 and calls works normally.

Haven't noticed any issues with UDP traffic, I have no offload enabled.

Thanks for that hint, I will improve the config later.
Maybe issue with the UDP traffic is just related to my ISP - each router that was connected there have same issue, but some were able to establish connection faster, than on BPI-R4, that's why I switch to SW offload. With or without sw offload - time for establish is same.

I have received the BPI-R5 and hope to find time to look at it this weekend. I'm not really familiar with OpenWrt yet.

I have so far only assembled the BPI-R5 with the original fan and housing and carried out a short function test by booting OpenWrt from an SD card. Everything seems to work.

Question regarding the fan:

  • What are your experiences with the fan?
  • As the router will be in my basement, the noise doesn't matter in the end. Nevertheless, I find it questionable that Bananapi suggests such a solution and not a larger passive heat sink. Some people will have the BPI-R5 in their flat. A fan is also a wearing part.
  • Is the fan temperature-controlled with OpenWrt? My impression is that it is off at the beginning after booting and only starts up after a while. The fan also doesn't seem to run continuously but keeps starting up. Seems strange to me.
  • My fan rattles or makes a noise like this. Is that normal?

are you sure your device is Banana PI BPI-R5 ?

Sorry. BPI-R4.

  1. It's surprisingly quiet. And I get annoyed by fans easily.
  2. I agree, I suspect it's to give headway for high power draw WiFi, the soc itself does not need it. There are options for fanless though. Not least of it increasing trip points so that's its for sure off while idle. I have a passive HS here but after noticing how quiet the fan is, I did not bother to try.
  3. Yes, easily configurable trip points, too. I think frank-w has an explanation somewhere on the official forum or his website
  4. No rattling is not normal.

I opened the case and pushed the cables down. Apparently the rattling is now gone. However, with the case open, the fan hardly seems to start at all or much later than with the case closed (Default Configuration without connection of any devices or Internet.).
