Hello,
I have a 2 gigabit plan but my modem doesn’t support the bridge mode.
Therefore I decided to use an OpenWRT router as a an access point. My OpenWRT box is a Cudy WR3000 which has one 2.5gb ethernet wan + 1gb lan links but unfortunately the modem offers 1gb ethermet links only.
So the stupid question is: Is it possible to use 2 ethernet links with the AP mode ? I have found some informations about the MWAN3 but I believe this works for WAN links and not for simple LAN links right ?
It has four gigabit ports. Please clarify. You can assign each to anywhere you want, lan, wan, pan , can , fan.
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 (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:
ubus call system board
And 1 x 2.5 Gbps WAN port. (Edit, the WR3000P)
I assumed the OP was trying to fully utilize their 2 Gbps Internet connection by using 2 x 1 Gbps ports to connect to 2 x 1 Gbps ports on the modem.
Yes

Certainly not MWAN, more likely LACP and bonding driver.
Remove 2 ports from br-lan, set up bonding link (search in package list luci-proto-bonding) LACP is mode 6
So it is 3000P not 3000NOTHING
Yes thank you.
Not without the “collaboration” of the modem: if has to support ethernet link aggregation, with a protocol compatible with OpenWrt.
... and you still won't break the 1gbit barrier for a single data transfer.
So I tried this:
I used mode 5 bonding (adaptative transmit load balancing)
Internet traffic is broken.
I found this error in the system log:
kern.err: [ 622.089818] bond0: (slave lan2): the slave hw address is in use by the bond; couldn't find a slave with a free hw address to give it (this should not have happened)
Ensure that each interface/device has its own Mac address.
Thanks. I set a dedicated mac address for lan1 and lan2. Works but download throughput (using 2 devices) is still limited to 1Gb. I see that all the incoming packets are going throught lan1 only. I use mode 6.
Could you please recap for me how each router and or AP is interconnected, and who has configured lacp or bonding?
That's correct. That was mentioned earlier in the thread.
If not done yet please consult https://www.kernel.org/doc/Documentation/networking/bonding.txt too
Devices are connected with WIFI. One of them is WIFI 6 and can reach 1Gb/s and the second one can reach about 600Mb/s. If I run the download test simultaneously the sum of throughputs is just under 1Gb. Yes I used the same speed test service. I just tested with 2 different speed test servers, it’s the same.
I assume one using 2.4 GHz and another on 5.4 GHz?
I also tried with a wrired computer and a phone (WIFI). The overall speed in OpenWRT is under 1Gb. If I connect the computer directly to the modem (phone still on the WIFI), the overall speed is about 1.8Gb. The bottleneck is not the WIFI.
correct, the bottle neck is the LAPC, as you were told a week ago.
The modem doesn’t support LAPC, that’s why I use mode 6 which implements load balancing based on ARP tweaks. LAPC is mode 4. I didn’t expect to get more than 1Gb/s per device, I only wanted to get more than 1Gb/s for all the devices connected throught WIFI overall.
