Scheduled Maintenance: We are aware of an issue with Google, AOL, and Yahoo services as email providers which are blocking new registrations. We are trying to fix the issue and we have several internal and external support tickets in process to resolve the issue. Please see: viewtopic.php?t=158230
Maybe you are missing the correct firmware package as your dmesg is saying "failed to load firmware". Do you know what device you have? Can you see it in lspci for example? Did you check the firmware folder if the config file is there or anywhere else?
The firmware package you mention does seems to say it supports the card seen by the kernel.
This is probably new hardware? Perhaps you need a newer version of the package.

Is it not dangerous? I need a stable system.
if you use the backported one, it is relatively safe, since the backporting team attempts to make newer packages that are compatible with the old packages on Debian 9. Your alternative is to wait for Debian 10 to come out (in a few months). You can also have both the old kernel from Debian 9 and the the backported one installed at the same time (in Debian 9). Then you can select which one to use from grub on boot (if you test it and see that it works but are not willing to go fully with the new kernel).

When will it come out Debian 10? Can this be known?

I have update the new kernel my debian-9.7.0-amd64-netinst.iso system. The new debian-9.9.0-amd64-netinst.iso kernel is real both debian-9.7.0-amd64-netinst.iso kernel? The new kernel is only for Debian 10? I would like reinstall my system if be published the new kernel, but if the 9.9 is old kernel, i not reinstall my system. Thanks your answer. Have a nice day!
