Wireless won't connect to WPA2 anymore
Hi,
I just installed Red Hat Enterprise Workstation 7.6 and my wireless card Code:
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34) /var/log/wpa_supplicant.log says the following about it: For my connection at home (just WPA2): Code:
wlp3s0: Trying to associate with 9c:c7:a6:a2:61:0d (SSID='MYSSID' freq=2412 MHz) Code:
wlp3s0: Trying to associate with 3c:0e:23:7d:6e:6f (SSID='eduroam' freq=5240 MHz) From the logs and Googling, I highly assume that it has something to do with the security profile that was set during installation of Red Hat (which was USGCB - US Government Configuration Baseline. I think that baseline prevents users from 'using unsecure ciphers' by blocking usage of said ciphers system-wide. If that is indeed the case: Why is it blocking WPA2-PSK and WPA2-Enterprise? Are those not 'secure ciphers'? How can I either set a 'secure cipher' to be used for wireless encryption or 'open the system up' to use the 'unsafe' ones? Some further info: The laptop in question also has Ubuntu Bionic and Windows 7 installed and wireless works perfectly fine in both. That's the main reason why I think it's just a matter of 'wrong' configuration of the Red Hat install. |

But I can't imagine it's relevant because: Who would use MD5 nowadays for anything? I can't imagine Red Hat or Cisco (manufacturer of the routers at work) or AVM (manufacturer of my router at home) doing anything that involves MD5... at least I strongly hope so! ;) No, I don't pay for Red Hat but my university does with a campus license. ;) I'm not sure if that qualifies me for customer support with Red Hat directly or if the university's IT support is responsible here? In either case: The uni's IT was unable to fix this. |

I have to use RHEL since that's what runs on our university's compute cluster which I'll have to use in a future project. I installed RHEL on my private laptop to get familiar with the system since I've never used RHEL before, only CentOS but that's almost 10 years ago. :D |

That adapter is fairly old; have you tried a newer one? Quote:
Again, since you're not paying for RHEL, I'd strongly suggest stopping where you are, and loading Mint, and chances are things will 'just work'. |

I WILL, however, try the firmware! Thanks for the link! Quote:

When the project starts, I will have to work DIRECTLY on the compute cluster where only RedHat is installed and I highly doubt the IT team will install Linux Mint or any other distro on their cluster just to make me happy. ;) Quote:

Again, have you tried downloading the firmware as suggested? Have you looked in the dmesg logs for anything related to the adapter?? Tried editing the file from the RHEL knowledgebase?? Quote:

Things have been suggested; either try them or not. Can't offer more advice when you haven't done/tried anything suggested so far, or posted any more details past "it won't connect". Good luck. |

Code:
Verification of signatures using the MD5 hash algorithm is disabled in Red Hat Enterprise Linux 7 I'm not an expert but that line sounds suspiciously like it enables verification of SSL connections using MD5 hashing somewhere (everywhere?) in the authentification process which nobody in the world should ever do past 200...4?

EDIT: Googling suggests that the option enables the use of MD5 for certificate verification which sounds like a good way to get your box compromised by the first script kid that finds your IP. |
