How to set up a Chinese router CF-WR625N?

Question

DHCP

The other day a router came from China: https://ru.aliexpress.com/store/product/COMFAST-CF... 192.168.10.1 is written on the back of the router.
I could not access this address until I configured the router and the computer to be on the same network. I am using ArchLinux.
Screenshots of the router settings:

DHCP comes from the provider, there is no MAC address binding.
ip l output:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 60:a4:4c:2b:3e:f9 brd ff:ff:ff:ff:ff:ff

But this is what I have in /etc/dhcpcd.conf at the end of the file so that my computer and router are on the same network (otherwise I couldn’t access it at 192.168.10.1):

interface enp2s0
static ip_address=192.168.10.2

Answer 1

I saw your question on two other forums. To you correctly advised - address to the provider!
Just tell those. support that they installed a new router and the Internet was gone. Prove them with this question.
Either hand it in as a faulty one (it's possible on Ali)
UPD: You have a working router - install it. Connect the Chinese (WAN port) to it (LAN port). PC to Chinese. Set everything up accordingly (I mean IP). If you appear on a PC with such a garland, then the Chinese router is working, finish off the provider. If not, take the router.

Answer 2

Yes, I try to solve the problem and understand and learn new things for myself.
