Linksys WRT1900AC V1 (throughput) is broken after DSA migration (OpenWrt 21/22/23)
The Linksys WRT1900AC's throughput is very poor after upgraded to OpenWrt 21, 22 and 23 where DSA replaced swconfig.
With OpenWrt 19, the Linksys WRT1900AC V1 can handle Gigabit (940Mbps) WAN to LAN throughput. However, it only does 350/800 Mbps with OpenWrt 21/22/23 (PPPoE). WAN to LAN throughput better for DHCP (780/660 Mbps), but still far away from the expected throughput.
For now, the only solution I have to improve the performance is downgrading the WRT1900AC to OpenWrt 19 where swconfig is being used. If you have any idea how to get a better throughput/performance with OpenWrt 21/22/23, please share in the comment section.
