To overcome the Chinese language barrier in the router settings, use the RUMIWIFI extension in your browser. Everything becomes almost in 2022. Has pros: Speed and power. As far as I could load the router as much as possible, at the same time I turned on a 4k movie on the TV from the PC over the air. The film ran great, the rewind worked well and forward and backward, without delay. Its cons: An unpleasant surprise was the lack of support for PPTP connections. But I found a way on the internet and the router worked.
