11.04 - Intel Wifi Link 5100 and Realtek 8188SU disabled

Asked by Natetronn

Hi,

I am trying to solve my wireless network woes on a brand new install of 11.04.

These are the commands and outputs that I have run (found from similar forums) and I am hoping get some incite since my situation is a bit different from others that I have seen in regards to the outputs (specifically rfkill list)

I have a external usb (Realtek 8188SU) and an internal (Intel Wifi Link 5100) which are both disabled. I have used the Intel in the past I think with 10.10 or maybe it was 10.04

Here is the terminal:

Do you have a switch to turn the wireless off and on?

Quick answer is yes, the internal has a switch.

I have a switch on the internal but, not on the external. I have tried with just the internal. With just the external (usb) I have tried with both which is what the output above has. I have tried with internal off and switching it off and on and rebooting etc.

Thanks

I am currently using both with Windows Vista (dual boot - same machine) so I know they are working and always have been.

Well, I used these commands:

username@ubuntu:~$ rfkill unblock 0
username@ubuntu:~$ rfkill unblock 1

And got this

username@ubuntu:~$ rfkill list
0: acer-wireless: Wireless LAN
 Soft blocked: yes
 Hard blocked: no
1: phy0: Wireless LAN
 Soft blocked: yes
 Hard blocked: yes

And now it seems to be working for the most part. Going to restart and see what happens.

One thing that is odd is if the hardware switch is off (Intel) then external usb (Realtek) doesn't seem to work. Maybe someone will have some thoughts on this. I don't know if it's driver or firmware is installed by default like the Intel Wifi Link 5100 was.

I will solve this after I have tested for awhile, thanks!

Does it work after a reboot?

actionparsnip yes it seems to be working fine now, wonder why these were set to be blocked by default both soft and hard.
