WiFi AllOther (49) My router accepts only 1/4" shank bits. Yet many of the bits that I would like to use have a 1/2" shank. Why are there not more 1/4" shank bits available?
1378I have a Wi-Fi network and would like to protect it from unauthorized access. It is better to use a RADIUS server that allows me to have 802.1x authentication and protection with WPA or WPA2 or use a Captive Portal that authenticates access via web login?
1 2364Why should not the user close the popup control window which appears after the authentication with the CaptivePortal?
1 2195Should an impostor capture the authenticator on the network and, without decrypting it, sends it as is to the captive gateway, could he or she obtain illegal access to the network?
1 2390If my wireless network doesn’t have a lot of traffic, is it okay to use WEP because the IVs required to crack the WEP key won’t be generated?
