I have http://www.amazon.com/Edimax-EW-7811Un-Adapter-Raspberry-Supports/dp/B003MTTJOY and I also have http://www.adafruit.com/products/814 and I’d trade a kidney to get either of the damn things working.
when i run
lsusb they both seem to use the same driver:
Bus 001 Device 002: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]
my logical device is wlan0. my etc/network/interface lines are:
iface wlan0 inet dhcp
wpa-ssid [network name here]
wpa-psk [password here]
when i fire it up via ifup or boot, ifconfig reports:
wlan0 Link encap:Ethernet HWaddr 80:1f:02:ee:68:ef
inet addr:10.0.0.33 Bcast:10.0.0.255 Mask:255.255.255.0

which you’d think would be good! my router hands out 10.0.0.* addresses and 10.0.0.33 looks good to me.
usually at this point i can get one or two pings in, maybe 3, but that’s it. i also notice after a reboot i usually can’t get any pings in to the same url, but i can get a ping or two to a different url. then i’m totally fucked.
so, i know i’m getting online fine, i can wget the google homepage and view it successfully, but shortly thereafter i’m done.
i’ve tried adding a bund of other lines to my interface file, such as wireless-rate auto, and wireless-channel 1 (or 11…i have two routers one on channel 1, one on channel 11, but neither works any better.
i tried moving my wpa info to a wpa_supplicant.conf file per other directions, but same result. pretty sure it’s the same thing, just different config files.
this is a brand new beagle bone black i just got from adafruit yesterday. it is running debian 7 wheezy.
totally stumped. any help would be immensely appreciated.
