Your WiFi card is apparently this one:

03:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] [8086:008a] (rev 34)

It is supported by the iwlwifi driver, which is included in the standard kernel package. Your adapter has been supported this way since kernel version 2.6.36. With some kernels, the driver module might be named iwlagn instead.

What you need is the firmware file for the adapter. In Debian 9, you'll first need to enable the non-free part of Debian repository if you didn't enable it when installing Debian in the first place. (Non-free here means "you don't get the source code for it", not "you must pay for it".)

then install the firmware-iwlwifi package using your favorite package management utility, then reboot and the driver should be auto-loaded and ready for use.

    Firmware is in the "non-free" Repository. If this is not installed into the sources list firmware-iwlwifi will not be available to the OP.

  • @arochester Intel 1030 should work with the included kernel module, adding non-free isn't required.

    @GAD3R The driver is free and included in the main repository, but the firmware is in non-free, because you don't get the source code for it. Debian is pretty serious about the principles of free software.

  • So, the driver apparently works and the next step is connectivity troubleshooting, which should be a different question altogether. Are you getting an IP address that matches the configuration of your WiFi network? Are you getting valid DNS server address(es)? Is the WiFi base station configured to restrict network access unless the client is specifically whitelisted or otherwise verified?

I download firmware-atheros_20210315-3_all.deb 1. Then just enter the Download folder and type at the console:

sudo dpkg -i firmware-atheros_20210315-3_all.deb

Тhen restart, and WiFi appear as а menu in Network Manager.

  • Just curious, did this resolve your issue with a Network controller [0280]: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] [8086:008a] (rev 34) as in the question, or with a different controller? I ask because "Atheros" isn't apparently related, but maybe it's not obvious. Thanks!
