I purchased an Alfa AWUSO36H USB card for wireless pen testing after hearing that it was well recommened on the backtrack message boards. I am using in on my new Kali install and i'm experiencing a few problems with the card. When im using it for internet purposes its very slow and when i try to download a file from the internet, the connection eventually drops and i cannot seem to reconnect to the wifi network. Below is some information which may provide helpful to more knowlegable users.
Below is the airomon-ng output:
This is the information being given when im trying to download a file, im about 15mBs into the download at this point:Code:root@kali-laptop:~# airmon-ng Interface Chipset Driver wlan1 Realtek RTL8187L rtl8187 - [phy2]
And soon after the connection drops and will not reconnect, it then shows the following information upon disconnection:Code:root@kali-laptop:~# iwconfig wlan1 && ifconfig wlan1 wlan1 IEEE 802.11bg ESSID:"PIKE168" Mode:Managed Frequency:2.437 GHz Access Point: 7C:4C:A5:1F:6A:F5 Bit Rate=54 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=70/70 Signal level=-15 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:2037 Invalid misc:48 Missed beacon:0 ----------------------------------------------------------------------------------------------------- wlan1 Link encap:Ethernet HWaddr 00:c0:ca:6d:9d:7a inet addr:192.168.0.8 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::2c0:caff:fe6d:9d7a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7940 errors:0 dropped:0 overruns:0 frame:0 TX packets:5073 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:11322396 (10.7 MiB) TX bytes:462625 (451.7 KiB)
I then looked at what modules the kernel was using for the card using lsmod, below is the relevant information:Code:root@kali-laptop:~# iwconfig wlan1 && ifconfig wlan1 wlan1 IEEE 802.11bg ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off wlan1 Link encap:Ethernet HWaddr 00:c0:ca:6d:9d:7a inet addr:192.168.0.8 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::2c0:caff:fe6d:9d7a/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:14725 errors:0 dropped:0 overruns:0 frame:0 TX packets:9201 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:21555532 (20.5 MiB) TX bytes:833677 (814.1 KiB)
