Hello, I've recently changed my wifi router and I'm experiencing something really strange with my wifi connection. If I try to connect to my access point using windows, I don't have any problem, but if I try with Linux (Gentoo Linux x86_64) I cannot connect to my Access Point unless I do the following steps: ifconfig wlan0 down rmmod iwldvm rmmod iwlwifi modprobe iwlwifi ifconfig wlan0 up otherwise if I try to connect to my access point / wifi router, Wicd tells me that I inserted a wrong password. I've even tried with another live linux distribution, and I don't have this issue. I use gentoo-sources-3.9.2 kernel. Anway, I see a lot of these lines into the ringbuffer: [ 10.597894] iwlwifi 0000:02:00.0: L1 Enabled; Disabling L0S [ 10.604842] iwlwifi 0000:02:00.0: Radio type=0x1-0x2-0x0 [ 10.974579] iwlwifi 0000:02:00.0: L1 Enabled; Disabling L0S [ 10.981532] iwlwifi 0000:02:00.0: Radio type=0x1-0x2-0x0 [ 11.170175] udevd (1281) used greatest stack depth: 3904 bytes left [ 11.177626] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 12.943205] ehci-pci 0000:00:1d.0: reused qh ffff88025442db80 schedule [ 12.943220] usb 2-1.2.4: link qh8-0601/ffff88025442db80 start 3 [1/2 us] [ 14.966790] ehci-pci 0000:00:1a.0: reused qh ffff880256313780 schedule [ 14.966809] usb 1-1.2: link qh1-0601/ffff880256313780 start 0 [1/2 us] [ 16.040474] r8169 0000:05:00.0 eth0: unable to load firmware patch rtl_nic/rtl8168e-3.fw (-2) [ 16.053919] r8169 0000:05:00.0 eth0: link down [ 16.053984] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 16.290113] EXT4-fs (sdb2): re-mounted.

Could you help me to debug the problem? I don't understand if this has something to do with my configuration or if there's a bug somewhere. the /etc/modprobe.d/iwlwifi.conf file is empty. Feel free to ask for further information you would need.
