Model: YouHua WR1200JS
I have been struggling with this WiFi issue for awhile. As far as I am aware, there has been a software/hardware offload openwrt bug with the MT7621AT chipset for awhile now causing WiFi throughput issues. Wired, I can achive Max 600/25 which is right on spec for my Internet connection. Wifi I max at 240/25. Configs:
config wifi-device 'radio0' option type 'mac80211' option path '1e140000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0' option channel '1' option band '2g' option htmode 'HT20' option cell_density '0' config wifi-device 'radio1' option type 'mac80211' option path '1e140000.pcie/pci0000:00/0000:00:01.0/0000:02:00.0' option band '5g' option htmode 'VHT80' option cell_density '0' option channel '48' option wmm '1' option country 'US' config wifi-iface 'default_radio1' option device 'radio1' option network 'lan' option mode 'ap' option ssid 'Wifi SSID' option key 'password' option encryption 'psk2+ccmp' option wmm '1'
firewall offload is enabled
config defaults option input 'ACCEPT' option output 'ACCEPT' option forward 'REJECT' option synflood_protect '1' option flow_offloading '1' # option flow_offloading_hw '1'
I found the original frmware that shipped with the router in post #150.
I combined the firmware with rar software on my ubuntu machine, rebooted, held down "wireless" button for 15 sec, and booted into "breed mode" to push the original firmware.
It defaults to 192.168.0.1. I tried to ssh in, but I wasn't able to figure out the login/password. No browser access either. If anyone that has this unit has solved the "offload" wifi speed issue, or knows the default user/pw of the original chinese firmware I'd like to test the original firmware to see if the wifi offload issue is still present.
