Router is ok, since my laptop can connect 5GHz. I tried 3.10 and 3.12 kernels (that I compiled myself) and many distros (both live and regular install), and they all exhibit the same problem. When attempt is made to connect 5GHz, I get: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 2126 at /home/kernel/linux-3.12/drivers/net/wireless/rt2x00/rt2x00config.c:201 rt2x00lib_config+0x293/0x2e0 [rt2x00lib]() Modules linked in: nls_iso8859_1 nls_cp437 vfat fat btrfs libcrc32c fuse vboxpci(O) vboxnetadp(O) vboxnetflt(O) vboxdrv(O) snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss ipv6 nf_conntrack_ipv4 nf_defrag_ipv4 xt_state nf_conntrack iptable_filter ip_tables x_tables dm_mod nvidia(PO) snd_hda_codec_hdmi acpi_cpufreq processor edac_core sp5100_tco arc4 rt2800pci rt2800lib rt2x00pci rt2x00mmio rt2x00lib mac80211 cfg80211 eeprom_93cx6 drm agpgart r8169 psmouse evdev mii thermal_sys mac_hid k10temp i2c_piix4 crc_ccitt i2c_core edac_mce_amd button hwmon rtc_cmos rfkill wmi serio_raw ohci_pci ohci_hcd kvm_amd kvm snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_page_alloc snd_timer snd soundcore microcode loop CPU: 0 PID: 2126 Comm: wpa_supplicant Tainted: P O 3.12.3 #1 Hardware name: To be filled by O.E.M.
