Hi.
I have installed openwrt 24.10 on my Sercomm H500-s from lowi (Spain)
Everything seems ok, I can use it and it does everything I need, but I have a performance trouble.
It can only reach 100mbps. If I test my network speed or download one big file (like one Linux ISO) the two cores of the H500 get 100% at 100mbps.
What can I do to solve the problem?
Get a faster/newer device.
Enable firewall soft offload, make sure no sqm is used.
Test at each step.

Post result links so we can say something wise
2-3x speedup expected, if that frees some CPU you get improved latency.
Or buy a new one from list (filogic aka mt79xx)
I searched for you, this is 10x faster than sercomm

Hi.
Thank you very much for your fast answer.
I've found how to enable firewall soft offload but I don't know how to search if I have any sqm in use.
Here you have the test:
https://www.waveform.com/tools/bufferbloat?test-id=5fa97212-a0ba-47f5-93f3-7f0f8ff66b5b
I have a little improvement about 20-30mbps more...
m4gn3to:
any sqm
Then probably not. run tc -s qdisc
in ssh - if it shows noqueue fq-codel and mq then certainly not.
ok, lets add 3 packet steering values to search space found in network/interfaces/global
try to srtucture tests:
no offload
sw offload
hw offload (no support in hardware but still uses different interfaces set which may or may not be better)
Out of 3 choose the best
Then roll through 3 steering options (default is "Enabled" , the middle one)
Then return and check through offload.
Post how it goes illustrating with waveform links.
Whats your subscribed speed? Also read service description, might be 50% guaranteed esp during weekend.
flows are for local traffic,quite expected they do nothing, only steering type matters for forwarding. disabled - enabled - enabled (all cpus)
EDIT: ie keep "hardware" offloading and walk through 3 steering options
none: all on cpu0
enabled: interrupts on cpu0 softirqs on cpu1
enabled(all) : interrupts on cpu0, softirq (firewall) in both cpus
Hi
Ok:
Steering disabled:
https://www.waveform_com/tools/bufferbloat?test-id=a56ed696-2d80-4f56-825a-5a98b8771920
enabled:
https://www.waveform_com/tools/bufferbloat?test-id=f696194f-5a5a-4640-b8b5-89ae37f8d746
Enabled (all cpus):
https://www.waveform_com/tools/bufferbloat?test-id=6fecd6bf-882a-4b8c-950b-5509df4b3b48
Sorry: I don't know why now the system tells me that I cannot post a link to that host...
m4gn3to:
system tells me
Dont worry, thats ice bucket if new user posts too loud
So leave steering default.
Unlikely much help, but you can try diagnosing unnecesary packet drops and whether doubling some of packet batching parameters reduces that.
i'd go shopping tomorrow if I was you.
Thanks.
I prefer not going shopping.
I used to use the T-Plink Deco M9 for the mesh wifi and as router, but I don't know why it stopped using ethernet backhaul and my wifi sucks (big house problems...)
I can go back to that config before going shopping...
Thank you very much. I'll read the doc you give ...

Let's be realistic here:
Broadcom BCM63167 (MIPS BMIPS4350), 2*400 MHz
totally unusable WLAN hardware (BCM63167 (<54 MBit/s) and QT3740BC (no support at all))
128 MB NAND flash
128 MB RAM
β¦it's time to go shopping, urgently.

Normal routers make better (mesh) coverage than mesh pucks.
You are right.
But I don't have budget to buy a new router now.
I have an "old" Intel(R) Celeron(R) CPU J3455 @ 1.50GHz laying around so I go x86.
I don't need wifi on the router I already have a mesh.
Thanks to your advices and tips now I have stable and fast internet.
By now...

2port netcard would be about same as arouter.
Also PC 24x7 will drive up electricity bills,
this 40β¬ will pay off vs the pc rather soon.

Wow. That price is very attractive...
I'm using a pico psu and 10-15w are not a big deal...
I could not find this device in the openwrt hardware list.
I've read it uses a custom version of Openwrt but I would prefer to use the original one...
Thank you very much.!!
Maybe a little offtopic but... do you know if I can install openwrt in an "Orange Pi Plus 2e" ?
I've searched in the forums but didn't find anything...
Thanks...
if it's not listed at https://firmware-selector.openwrt.org/?version=SNAPSHOT , it's not supported.
you need to figure out what the Plus and e in 2e stands for.

You need an extra sd card to try?
