The card can see access points, but thats about as good as it gets as trying to connect to any networks ( either 2.4 ot 5 Ghz ) results in the following, wlp3s0: CTRL-EVENT-SCAN-FAILED ret=-22 retry=1 ( alot of these ) which then resets connection status with a failed timeout. I am currently running FedoraCore 30 with the 5.2.5-200 kernel updated from 5.1.x yesterday. The firmware loaded is, loaded firmware version 9.221.4.1 build 25532 op_mode iwldvm Now with all that said, using a Linux Mint live boot from a usb device yeilds the card working fine at both 2.4 and 5ghz speeds, it connects within seconds. The kernal in this live boot is 4.15.x and uses the same firmware build as my FC install. I did see strange behavior with this card from around 4.18 to 20, thinking the card might have developed a fault and obtained a new one. This proved that this was not the case as I get the exact same behavior from both cards. Hope this information is helpful to solve quickly, please reach out for more information if required Thanks Nige -- “Science is a differential equation.

It's hard to tell exactly what is causing that without further investigation. Are you able to compile the kernel and do some tests? One way you could do it is to replace the -EINVAL with a line number, so we can try to see where the invalid parameter error is coming from. Doing something like this: http://pastebin.coelho.fi/03fa29d951db5405.txt > > Then the returned error should correspond to a line number on the driver. > > Another thing you could try is to bisect the kernel between the last known good version and the one that fails.

The kernal in this live boot is 4.15.x and uses the same firmware build as my FC install. I'm also using a "Intel Corporation Centrino Ultimate-N 6300 (rev 3e)" card and it's working perfectly with 5.3.0-rc4-wt here. (And with most wireless-testing kernels for the last years, too..) Now there was one noteworthy bug in the last year we handled on the mailing list: https://lore.kernel.org/linux-wireless/87k1rk1af5.fsf@kamboji.qca.qualcomm.com/ But then this was a null pointer and does not match to what you observe. (And that really should be fixed in any 5.2 kernel...) I'm using a Gentoo ~amd64 system and wpa_supplicant more or less tracking git upstream and the wireless-testing kernels with the same firmware as you. So whatever it is, it's not affecting me. I would suggest to try a vanilla 5.2 kernel and maybe also an updated wpa_supplicant version next... Alexander ^ permalink raw reply [flat|nested] 6+ messages in thread

I stumbled across a Red Hat bug report[0] involving 'CTRL-EVENT-SCAN-FAILED ret=-22' and the proprietary broadcom driver. A comment there[1] describes a workaround for their issue, by making NetworkManager not randomise the MAC address during access point scans. Adopting that workaround also works for my Centrino Ultimate-N 6300 (rev 3e). Create a config file /etc/NetworkManager/conf.d/iwl.conf with contents: [device] match-device=driver:iwlwifi wifi.scan-rand-mac-address=no Then restart NetworkManager. Alternatively, downgrading wpa_supplicant (to 2.7-r3 on Gentoo ~amd64) also works for me. - Antanas [0] https://bugzilla.redhat.com/show_bug.cgi?id=1703745 [1] https://bugzilla.redhat.com/show_bug.cgi?id=1703745#c56 ^ permalink raw reply [flat|nested] 6+ messages in thread

I have a Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) wifi card instaled. From the Intel technical support I received the information, that this card is dual band and supports 5GHz standard. I cannot see this network, but only 2,4GHz one. I have Ubuntu 12.04 instaled and tried to update given below drivers. I am afraid I need a help with this process. Would you be so kind and give me step by step manual, how to update the intel drivers (together with needed commands, if possible)? Thank you in advance. . ---------- Forwarded message ---------- From: <support.replies@mailbox.intel.com> Date: 2014-01-30 Subject: {ticketno:[8000861141]} - Your Intel Customer Support Inquiry Dear Sir, Thank you for contacting Intel Customer Support.
