i think wireless driver is missing..please help me I am really frustrated...
Thank you..

[Pjotr]

The driver isn't the problem. This is:

Code: Select all

rahul@rahul-Inspiron-5547 ~ $ rfkill list all
0: dell-rbtn: Wireless LAN
Soft blocked: yes
Hard blocked: yes

Both a soft block and a hard block.... That's pretty formidable.

Is there a physical switch or an Fn key combination with which you can switch Wifi on? If so, do so. That should take care of (at least) the hard block.

Then run this command:

Code: Select all

rfkill unblock all

.... to take care of lifting the soft block.

[rahulkumar]

but wifi is working properly in windows..it shouldnt work if it is blocked by some button or hardware..
also i tried "rfkill unblock all" and i got this..

rahul@rahul-Inspiron-5547 ~ $ rfkill unblock all

A very new wifi chipset to Linux, lets see the result of

Code: Select all

lspci -nnk | grep -iA2 net; modinfo iwlwifi | grep -i 08b3; dmesg | grep iwl

[rahulkumar]

sorry for the late reply ..here is the output of "lspci -nnk | grep -iA2 net; modinfo iwlwifi | grep -i 08b3; dmesg | grep iwl".

[JeremyB]

See if the FN combo will enable the wifi as the hardware is supported by the kernel you have and firmware loaded. The dell_rbtn module is supposed to support it

[rahulkumar]

problem solved!!
you were right..i enabled wifi using PrtScr key with Fn key..(key with the little radio tawor simbol
many thanks..
