USB on the Pi seems to be quite the puzzle. However, the wlan adapter worked OK in the Pi USB slot. My unit has the poly fuses, so I didn't expect there to be adequate power on the Pi's USB port. I did try the wlan adapter in the Pi USB port. It's interesting to note that another wlan adapter worked fine off the second hub within the 7 port hub.

If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version. I have a USB memory stick on that second 4 port hub that seems to work fine, so the issue would seem to be specific to the wlan USB adapter. The package provides the installation files for Airlink101 Wireless Cardbus Adapter MediaTek Driver version 5.0.57.0. Given that this makes the adapter work, I suppose that the second 4 port hub could be connected off the 4th port on the first 4 port hub within the 7 port hub) and somehow there is an issue connecting via the downstream hub. The downlink via the wlan0 measures about 2.3 Mbps, which is about the same as the eth0 interface. I reconfigured turbo mode and changed the cabling so the Pi is also powered off one of the ports on the second 4 port hub (within the 7 port hub) and rebooted successfully. That first hub also has the keyboard and mouse.
#Airlink101 wireless adapter speed mac#
Wonder of wonders, moving the AWLL6975 to a port on the first USB hub (within the 7 port hub) made the MAC address show up correctly and connected to my router using the SSID/Key info correctly. With the adapter that worked, the MAC address of the adapter appeared in the Listening and Sending lines and the DHCP server assigned an IP addressĪny idea what the issue might be with this adapter and how I might fix it? However, executing sudo ifup wlano produces:ĭHCPDISCOVER on wlan0 tp 255.255.255.255 poet 67 interval 5ĭHCPDISCOVER on wlan0 tp 255.255.255.255 poet 67 interval 2 Running iwlist wlan0 scan produces a valid enumeration of the access points available, so the driver can receive data from the adapter. usbcore: registered new interface driver r8712u r8712u: Loading firmware from "rtlwifi/rtl8712u.bin"

With the AWLL6075, i see the following in the dmesg output: On this adapter, I see the MAC address for the adapter displayed.
With the other adapter I see it request an IP and one is assigned. I have previously successfully connected to the internet via my wlan using another adapter in the same hub, so I believe my wireless settings are correct for the SSID and password. I have the subject adapter plugged into a powered USB hub on the latest raspian imagecat.
