Try 24.10rc6? I'm running 24.10rc6 on my R5C gateway and internet speed is fine. It's handling ~450 Mbps CAKE SQM download (I have 600/20 ISP service) over a distant WiFi AP with just a quick test now. It's faster on a wired connection (WiFi is holding it back, not the R5C), but suffice to say I'm not limited anywhere near to 175Mbps.

No joy.
The Snapshot and 24.10.0-rc6 only allow for about 95mbps down and up. With FriendlyWrt it’s averaging 700mbps down and 185mbps up.
Test is being run from TP-Link Deco BE25 connected directly to the r5c via 2.5gps port.
OpenWrt 24.10.0-rc6
Sorry to hear it didn't work out.
Probably you've already tried this, but installing without keeping your configuration and re-configuring using a backup as a guide might fix a hidden issue. Or not. It could just be a waste of your time.

Have you adjusted the net-smp-affinity?

I reinstalled squash from scratch each time. Tried the latest OpenWrt Snapshot and the latest RC supporting the NanoPI R5C.
No. How do I do that?
Install WinSCP - login into your router.
Navigate to the /etc/hotplug.d/net folder
in there you will see a file called smp-affinity, can you post the R5c?
will look something like -
friendlyarm,nanopi-r5c|\
-radxa,e25)
+radxa,e25|\
+sinovoip,rk3568-bpi-r2pro)
set_interface_core 2 "eth0"
set_interface_core 4 "eth1"
find /sys/class/net/eth*/queues/[rt]x-[01]/[rx]ps_cpus -exec sh -c '[ -w {} ] && echo f > {} 2>/dev/null' \;
;;
add in the find/sys/class line as is will set queues to all 4 cpu, but also try changing it to 3 (rather than f), which will just use the first 2 cpu as i think from default eth* are pinned to cpu 3 and 4. I don't own a R5C so this is may be different, I use a R4S and R6S.
Your methoid worked. I'm about to sysupgrade to -rc5 with owut and would like to use --rootfs-size ROOTFS_SIZE option of owut.
What should be the size put here not to expose myself on bricking the device?
1040 mentioned in this post from September?
I guess that doing upgrade with rootfs size will allow to expand and sysupgrade in place with biggger storage.
Regarding /etc/hotplug.d/net' there's no definition hhere for r5c:
case "$(board_name)" in
armsom,sige7|\
friendlyarm,nanopc-t6|\
friendlyarm,nanopi-r3s|\
friendlyarm,nanopi-r5c|\
friendlyarm,nanopi-r6c|\
But in LuCi - Interfaces->Devices->Global options I can see:
turned on. Maybe this will help?
This must be in that 40-net-smp-affinity file.
Can anyone confirm that I can safely upgrade with owut and declare bigger rootfs size?
I'd like to upgrade to newest stable but also make rootfs bigger.
EDIT/UPDATE:
September 2025 - owut rootfs size increase: no issues from 24.10.2 to 24.10.3, rebooted with 1024MB space for rootfs
I use imagebuilder and run this:
# edit .config file and increase CONFIG_TARGET_ROOTFS_PARTSIZE=256.
sed -i 's/^CONFIG_TARGET_ROOTFS_PARTSIZE=104$/CONFIG_TARGET_ROOTFS_PARTSIZE=255/' .config
I would like to use this device and openwrt firmware to create an AP that connects Wifi and 2.5G ports. My question is, is the device capable of transmitting the almost full 2.5Gbps data between the two 2.5G ports?
Using OpenWRT, even with the latest 25.12 RC’s or snapshot, been able to get the NanoPi R5C’s LAN and WAN ports to operate as fast as they do with FriendlyWRT or ImmortalWRT. Using iperf3 -R the speed is ~ 300mbs with OpenWRT as apposed to 1.3gps with the other firmwares.
I’m assuming this had something to do with the rk3568 support.
Anyone found a solution for the standard OpenWRT firmware.
Thanks, Goody
Using 25.12 rc3 and rc5, I get the maximum speed from my isp, 2gbits/s.
How are you checking speeds?

It is strange for me to see your local address (line 4, begining with [5]) in a local subnet. Are you using double NAT ?
