Hello, I'm working on support for for Jensen AL3000DG v2 device (ramips target, currently build on r47048). The device is similar (but not exactly the same) to Edimax R-6475ND and Asus RT-N56U.
Short specification: - RT3662F (for 5 GHz radio) - RT5392L (for 2,4 GHz radio) - RTL8367R Gbps switch - 8 MB SPI NOR FLASH - 64 MB DDR2 RAM - 2x PCB antennas (with 2x SE5005L PA for 5 GHz radio) Support is mostly done, everything seems to work, but during final tests I encountered a strange problem with WiFi. I'm not able to use 2,4 GHz radio without enabling 5 GHz radio at the same time (this problem doesn't exist on OFW). If I enable both radios in configuration, both are up and I'm able to connect and use them. The same if I enable only 5 GHz radio (inside RT3662F) - it's visible and working. If I enable only 2,4 GHz radio (RT5392L) - it seems to be up (at least iwinfo and iw report that - see below), but I don't see the SSID in the air. I would be grateful for any advice how to debug that. Full bootlog is available at [1], iw list output at [2] and dts file at [3]. ----- Some outputs, only 2,4 GHz radio enabled in config: root@OpenWrt:/# iwinfo wlan0 ESSID: "OpenWrt_2G" Access Point: 34:21:09:xx:xx:xx Mode: Master Channel: 11 (2.462 GHz) Tx-Power: 20 dBm Link Quality: unknown/70 Signal: unknown Noise: unknown Bit Rate: unknown Encryption: none Type: nl80211 HW Mode(s): 802.11bgn Hardware: 1814:3091 1814:3091 [Generic MAC80211] TX power offset: unknown Frequency offset: unknown Supports VAPs: yes PHY name: phy0 wlan1 ESSID: unknown Access Point: 00:00:00:00:00:00 Mode: Client Channel: unknown (unknown) Tx-Power: 0 dBm Link Quality: unknown/70 Signal: unknown Noise: unknown Bit Rate: unknown Encryption: unknown Type: nl80211 HW Mode(s): 802.11an Hardware: unknown [Generic MAC80211] TX power offset: unknown Frequency offset: unknown Supports VAPs: yes PHY name: phy1 root@OpenWrt:/# cat /etc/config/wireless config wifi-device radio0 option type mac80211 option channel 11 option hwmode 11g option path 'pci0000:00/0000:00:01.0/0000:01:00.0' option htmode HT20 config wifi-iface option device radio0 option network lan option mode ap option ssid OpenWrt_2G option encryption none config wifi-device radio1 option type mac80211 option channel 36 option hwmode 11a option path '10180000.wmac' option htmode HT20 option disabled 1 config wifi-iface option device radio1 option network lan option mode ap option ssid OpenWrt_5G option encryption none [...] [ 15.550000] PCI: Enabling device 0000:01:00.0 (0000 -> 0002) [ 15.560000] rt2800pci 0000:01:00.0: failed to load eeprom property [ 15.570000] ieee80211 phy0: rt2x00lib_request_eeprom_file: Info - Loading EEPROM data from 'rt2x00pci_1_0.eeprom'.
