2 cards for testing
wusb54g (does not suport master mode)
AWUS036NHA (just got this card yesterday)
kali 1.0.9 raspberry pi b+

i have 2 cards for testing... ill start with airbase-ng as it will support both cards...

upstream=eth0
phy=wlan0

service network-manager stop
rfkill unblock wlan

ifconfig $phy down
iwconfig $phy mode monitor
ifconfig $phy up
iwconfig $phy rate 5.5M fixed
airbase-ng $phy -c 6 -P -C 60&
sleep 5
ifconfig at0 10.0.0.1 netmask 255.255.255.0 up
route add -net 10.0.0.0 netmask 255.255.255.0 gw 10.0.0.1

dhcpd -cf /etc/mana-toolkit/dhcpd.conf at0

echo '1' > /proc/sys/net/ipv4/ip_forward
iptables --policy INPUT ACCEPT
iptables --policy FORWARD ACCEPT
iptables --policy OUTPUT ACCEPT
iptables -F
iptables -t nat -F
iptables -t nat -A POSTROUTING -o $upstream -j MASQUERADE
iptables -A FORWARD -i at0 -o $upstream -j ACCEPT

so, you notice i have set rate to 5.5M fixed, from what i understand this will lighten the load (smaller chunks of data) with out this the usb device will dissconnect and reconnect do to (over-current)
with out a lower fixed rate, a client will connect and when data is sent over that is to large you will then see over-current happen
the script above works well with the old ugly wusb54g...

so, i got my new alfa card and figured all should run with out a problem... after the alfa card is placed into monitor mode, this error shows when you attempt to set a fixed rate

iwconfig wlan0 rate 5.5M fixed

with out lowering the rate. a client connects and when large data passes threw almost instatly the device is disconnected.

So now since my new card suports master mode i get to test hostapd ,-) but almost the same symptoms exist

/root/projects/mana/run-mana/start-nat-simple.sh

./start-nat-simple.sh

So, the thing is up and running, the symptom is almost the same as i explain with airbase...
my phone connects to this new access point, if i quickly refresh a webpage data begins to pass threw, i must click quickly or else dissconnect and reconnect happens with this slightly new error

can this wakeup script be disabled? Edited by i8igmac

The way I'm looking at it, the internal USB hub on your Pi seems to be a complete POS. Are your wifi adapters demanding more current from the USB port than the Pi can provide? Did you consider connecting everything up via a powered USB hub to see if the problems go away?
