Hi!
I just installed latest Kali 2018.2 and encountered a problem with weak wifi signal. I have two adapters, one internal Broadcom Limited BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 02) and external TP-LINK 722N. The strange thing is that on BOTH adapters I have very weak wifi signal strength comparing to when I'm in macOS.
iwconfig shows:
Code:
wlan1 IEEE 802.11 ESSID:"XXXXX"
Mode:Managed Frequency:2.462 GHz Access Point: 6C:70:9F:EA:FE:10
Bit Rate=72.2 Mb/s Tx-Power=20 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality=47/70 Signal level=-63 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:181 Missed beacon:0
wlan0 IEEE 802.11 ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=31 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
So, I'm 7 meters from access point, and I'm only able to connect to it with wlan1, which is usb TPLINK 722N adapter. What is strange is that even being so close to AP it says that link quality is only 47/70. At the same time, internal broadcom adapter (wlan0) is unable to connect to AP at all even having the TX POWER set to 31. When I'm 1meter away from AP I'm able to connect to it using internal adapter, BUT link quality in that case is also around 40 of 70. Also internal adapter doesn't see any other wireless networks around. But when I'm booted in macOS it sees a lot of it, and signal is very good.
What could it be? Is there something could be done with that?
Thanks in advance for help!
