Wireless authentication problems

Hi. I’m having problems with the wifi on a new, fresh install of 13.2

Running KDE

Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01)


Linux linux-8v1z.site 3.16.7-7-desktop #1 SMP PREEMPT Wed Dec 17 18:00:44 UTC 2014 (762f27a) x86_64 x86_64 x86_64 GNU/Linux



The problem seems to be related to security. I was using the wifi just this morning at a hotel ( browser based security ) here with WEP, as soon as I enter the passphrase, in NM tools, the OK goes grey. If I click on connect, has soon as I enter the key, the connect button ceases to respond.

Any Ideas?

Examine /var/log/NetworkManager for more dialogue. (You may need to use ‘journalctl -u NetworkManager’ instead.)

You mentioned WEP, and using a passphrase (rather than a hexadecimal character string). Are you sure that it is not ‘WEP key 128 bits’? Try setting up the connection via the NM connection editor. (There are two types of WEP protocols to chooes from.)

Here is the entries from Journalctl wrt wlo1


Dec 26 15:23:35 linux-8v1z.site NetworkManager[750]: <info> (wlo1): device state change: unmanaged -> unavailable (reason 'managed') [10 20 2]

Also, checked WEP type set for

WEP key 40/128 bits (Hex or ASCII)

Same thing, as soon has I set security, “OK” greys out and connect doesn’t work.

Thanks, I will keep hoping.

Yes, but there are two choices for WEP:
WEP key 40/128 bits (Hex or ASCII)
WEP key 128 bits

For a WEP passphrase (which you referred to), you need the latter.

Despite the fact the NM requests the pass phrase, it will ony accept the hex equivelant
I consider this is still a bug, but at least it’s working.

Thanks for the assistance.

Now, on to SANE

Yes, but that is because you’d chosen ‘WEP key 40/128 bits (Hex or ASCII)’ instead of ‘WEP key 128 bits’ if I understood you correctly. Now you report that you are able to connect, is that correct?

Thanks for the assistance.

Glad to have been of help.

Now, on to SANE

Start a new thread fo for that if needed and I will try to help.
