How to enable wifi

[YasuhideOmori]

Hi!
This is the first time for me to install Debian
but there is a trouble, wifi.

Installer could show me the list of SSID, and recognised.
But offline installer never enable me to use wifi.

dmesg says:

Do you not have some hard-ware switch on it?
Try

Code: Select all

nmcli radio wifi on

, but I am afraid, that will not help with hard-blocked...

[Head_on_a_Stick]

$ /usr/sbin/rfkill
ID TYPE DEVICE SOFT HARD
0 wlan phy0 unblocked blocked

Check for a hardware switch for the wireless card, if you are sure it is turned on then check

Code: Select all

lsmod

for any vendor-specific modules that may be interfering, try blacklisting any that you find.

Sorry for writng too late

I use NEC laptop and wifi inside
When I boot Windows, I can use IEEE802.11a/b/g without any special setting

Of cource the result of "lsmod" has no trouble, and, I don't know why but once after booting Windows by replacing disk Wifi was recognized, but just once.
Moreover only IEEE802.11b/g was available.

It seems that the EEPROM of the chip inside the NEC laptop is unnusual, but
$ cd /var/tmp
$ tar axf
$ patch < the_patch_provided_for_nec_alt5k
$ make old config
$ make modules

the ko file was not available(/sbin/modprove -v show me an error).
make --prefix=/vartmp/root module install might be a solution but I don't try it yet ...

I think I read once upon time somewhere Windows likes writing into firmware without owners permission - well, if you run Windows then you really don't own your computer, you are a licensed user at best. By installing Windows you agree to hand over the rights to the hardware to Microsoft. Anyhow, I recall Windows may disable the Wi-Fi in firmware when shut down. But then again, my last Windows crashed in 2003, so you can take it all as hearsay.

Hm ...
There is no problem if I use Vista by using HDD
When I change to SSD(Debian 10.0 buster) wi-fi doesn&t work, moreover even if booting Vista IEEE802.11a ' s SSID was shown

Is there some firmware for this kind of stupid EPROM?

[Segfault]

I meant the motherboard firmware. If the card is disabled in motherboard firmware it cannot be enabled by rfkill.
