Hi, the OpenWrt in use is Tp-link Archer A9 V6 US.
-The isp is a ftth, it's router is in bridge mode.
-The WAN network is not working well.
-The speed test works at half of the contracted speed.
-The same test with a dd-wrt router works well, at 100%.
-Both test were done with a ethernet cat7 cable.
Is there any simple guide to get started in OpenWRT?
Which part of the log should I pay attention to check if everything is working well?
Wired vs wireless performance?
Are you using CAKE/SQM?
Router / bridge mode as in the ISP "router" is acting as media converter?
Archer A9 v6 looks to be QCN5502 ( mips24kc single core @775MHz) ? I'd be thinking router offload vs CPU doing routing could be the issue?

How fast is the ISP internet speed?
Edit: regarding a quick look at ath79 sqm performance.
Looks like we're talking 100-300mbps before CPU tops out?
Edit: Yeah looks like there's hardware flow offload on this target. Not implemented in openwrt?
1- Wired
2- No.
3-Yes
4- Memory Available 53% Used 34%
5- 300 symmetrical megabits per second (Mbps)
Noted.
So you achieve ~150Mbps?
What is CPU doing when doing speed test? SSH and 'top' ? But yeah my initial thoughts is this target just can't route that fast through CPU.
Let's take a look at the config to make sure there aren't any obvious issues:
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
Check your network cables...
I have the similar trouble, caused by a bad network cable.
Good luck!
