Why doesn't dd-wrt give ip when booting 2os?

Question

linux

In general, the question is the following, there is a router with dd-wrt, there is a computer with 2 disks on one, there is WIN on the other LINUX.
When loading win, there is Internet and there are no problems, when loading into linux (Arch is now installed, before that it was Debian) there is no Internet, the router simply does not give ip, when executing the ping 8.8.8.8 command, it says no connection. I try to assign a static ip to arch, but the ping only goes to the router (ping 192.168.1.1).

You should not think about linux, since there are no problems with Raspberry Pi, it has an Internet. Also connected to this router.
Who has experienced this?
