Hello fellas.
So, I updated BT5 to BT5 r1 and now airodump-ng stopped showing signal strength using zd1211rw chipset wifi adapter, rtl8187 works fine.

rtl8187 is wlan0 is mon0
zd1211rw is wlan1 is mon0

#: airmon-ng start wlan0
Code:
Interface	Chipset		Driver

wlan0		Realtek RTL8187L	rtl8187 - [phy0]
				(monitor mode enabled on mon0)
wlan1		Zydas zd1211b	zd1211rw - [phy1]
#: airmon-ng start wlan1
Code:
Interface	Chipset		Driver

wlan0		Realtek RTL8187L	rtl8187 - [phy0]
wlan1		Zydas zd1211b	zd1211rw - [phy1]
				(monitor mode enabled on mon1)
mon0		Realtek RTL8187L	rtl8187 - [phy0]
Now, let's scan some APs

#: airodump-ng mon0

-36% is 100% - 36% = 64% signal strength

Now, let's use zd1211 adapter

Zero, zero, zero.

I really need to zd1211 work, becouse it's my main adapter and it has antenna, so it works better than rtl8187.
How to fix it?
Also, how do I change the way he's showing signal strength, from -36% to 64%?

I've tried to download zd1211 driver and install it manually, doesn't help. In fact, drivers were the same, byte to byte.

Who's not doing he's job, is it aircrack-ng fail?
