** All, please note that a few things need to be made clear as things have changed slightly since my last post here some weeks ago:
1. Due to this and other issues, I did a re-install (retaining my /home partition, though). Things did not improve, save for:
2. All I have to do now, in order to get the card working on KDE start-up, is simply to, as root, issue the command 'modprobe -r rt61pci', and the card connects.
Beware, though, before you come to the conclusion that it is the rt61pci driver that stands in the way, that it seems to reload that same driver (according to PCC->Hardware) automatically and then connect.
apparently there are two driver available for your card (ralink rt61 chipset): rt61pci (also called Legacy), and a new rt2x00pci
the rt2x00pci is available with PCLinuxOS kernel 22.214.171.124 and with kernel 126.96.36.199 (I have this two installed on my system), so I think is available with any kernel from 188.8.131.52 up the the current.
Worth to try if the new driver may work better, then may be you need to blacklist the rt61pci and manually load the rt2x00pci.
If something is not clear please ask.
AS, I wasn't even remotely aware that this was the case! I have searched on the card and all references I have found have always been to the rt61pci. As I am far from the only one that have had issues with this driver, this is indeed good news! I shall try to follow your advice and post back. I might indeed need some help along the way, but I shall give it a shot. Thank you so much for this info!
Regarding the 3 previous cards, did you ever remove the config for those cards from PCC?
Jase, I did indeed, thank you. As per my note above, it has become a moot point in the meantime, though...
This sounds like a driver conflict. You might want to try blacklisting all wireless modules and then enabling only one for installation at boot.
If AS' advice above does not work, I shall try this approach. I might need to ask a little help to locate all the drivers I need to blacklist. I shall ask if and when it becomes necessary. Thanks.
Jase, as per your request (all as root):
