Bad news for the moment when you look here for Debian: https://wiki.debian.org/rtl819x
And: https://git.kernel.org/pub/scm/linux/ke … e/RTL8192E

You would need a non-free firmware-blob loaded at runtime, which is not supported for GNU/Linux-libre as our kernel.

Ok, i change my chipset, thanks for news

You mean you are using a wired connection in combination with dhcp, correct?
A wireless connection would be the same in regards of the ip-address and its reaction towards dhcp.

It is not clear for me therefore: Have you used wired or wireless connection for installation? I ask therefore because I have doubts if the card is working for now.

There is more information needed as it is unknown what kind of hardware is used: USB-adapter? Internal card? Also: At what point do you have problems? Is it the installation or the running system?
