While my android smartphone has around a dozen different wifi networks available, I can’t get this card get more than two at best.
lshw -c network reports:
*-network description: Wireless interface product: AR922X Wireless Network Adapter vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:0f:00.0 logical name: wlan0 version: 01 serial: da:45:28:45:56:30 width: 32 bits clock: 66MHz capabilities: pm bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=3.16.6 firmware=N/A latency=168 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:18 memory:fa300000-fa30ffff
rfkill doesn’t report that the device is blocked in any way
# rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no
It shows up in iwconfig
# iwconfig wlan0 wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=16 dBm Retry short limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off
And ifconfig can get the interface up
# ifconfig wlan0 up # ifconfig wlan0 wlan0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 ether da:45:28:45:56:30 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
iw dev wlan0 scan however, reports too few results, so the AP I am trying to connect to, is unavailable despite the fact, that even my smartphone that currently uses it, says that the signal is ‘good’. It’s a public AP, so I don’t think that there is some kind of MAC filter or a limited count of peers. The AP isn’t hidden or anything like that, so how do I widen the range of available networks? The card is discrete and has three separate antennas, so I don’t understand how this card can be weaker than the one in my smartphone.
I don’t know why, but today the card has found the AP, though its signal was only -60 dBm while the one’s that’s always seen was -58. I didn’t do anything, not even shutdown or sent it to hibernation actually. Maybe that’s the weather. The card, however, doesn’t show more than two APs in scan results.
CRDA region is 00, which stands for global. The output of
iw dev wlan0 scan from today if somebody interested, is here http://sprunge.us/QWPY
