- Note be careful not to convert a binary file to text during the transfer process it is easy for this to occur since many programs use text files by default 380
- Note exit or must follow sub commands if it is to make the nxc exit sub command mode 380
- The commands in my configuration file or shell script are not working properly 380
- The nxc s traffic throughput rate decreased after i started collecting traffic statistics 380
- I cannot get the firmware uploaded using the commands 381
- My earlier packet capture files are missing 381
- My packet capture captured less than i wanted or failed 381

- Both wpa and wpa2 improve data encryption by using temporal key integrity protocol tkip message integrity check mic and ieee 802 x wpa and wpa2 use advanced encryption standard aes in the counter mode with cipher block chaining message authentication code protocol ccmp to offer stronger encryption than tkip 436
- Eap md5 eap tls eap ttls peap leap 436
- Encryption 436
- For added security certificate based authentications eap tls eap ttls and peap use dynamic keys for data encryption they are often deployed in corporate environments but for public deployment a simple user name and password pair is more practical the following table is a comparison of the features of authentication types 436
- If both an ap and the wireless clients support wpa2 and you have an external radius server use wpa2 for stronger data encryption if you don t have an external radius server you should use wpa2 psk wpa2 pre shared key that only requires a single identical password entered into each access point wireless gateway and wireless client as long as the passwords match a wireless client will be granted access to a wlan 436
- If the ap or the wireless clients do not support wpa2 just use wpa or wpa psk depending on whether you have an external radius server or not 436
- If this feature is enabled it is not necessary to configure a default encryption key in the wireless security configuration screen you may still configure and store keys but they will not be used while dynamic wep is enabled 436
- Key differences between wpa or wpa2 and wep are improved data encryption and user authentication 436
- Note eap md5 cannot be used with dynamic wep key exchange 436
- Nxc series user s guide 436
- Select wep only when the ap and or wireless clients do not support wpa or wpa2 wep is less secure than wpa or wpa2 436
- Table 222 comparison of eap authentication types 436
- Tkip uses 128 bit keys that are dynamically generated and distributed by the authentication server aes advanced encryption standard is a block cipher that uses a 256 bit mathematical algorithm 436
