A. issuing IP addresses to wired devices
B. mitigating threats from the internet
C. providing authentication services to users
D. managing interference in a dense network
E. Layer 3 routing between wired and wireless devices
mine home Linksys Wireless router does A and E,
it also maybe B. mine sort of does B, depending what they mean mitigate. but mostly u have Firewall to do that and firewall u need on PC, so A E will do.
Wireless router does some functions of Firewall, Access point, Switch, Router all together. So wireless router is entirely different from wireless controller. Right? The question is regarding wireless controller.
maybe, i thought this is about wireless router
so what is wireless controller ? i did not found definition, see https://en.wikipedia.org/w/index.php? title=Category:Wireless_networking&pagefrom=Super+Wi-Fi#mw-pages
is it Wireless LAN controller ?
yes, if I'm not wrong
Anybody knows the answer?
