Using 31 access points in a building, 3 at location A, 2 at location B.
currently channel width is set to 20Mhz globally.
now i have just a simple query, that will there be any effect / side effect on my currently running wireless network if i change channel width from 20MHz to 80 MHz ?
then install 802.11ac modules in access points.
Thanks

Hello I am unable to telnet a Cisco 2811 router, but all the links connected to router are operational means router is working fine. (BUT SOMETIMES all the links connected to that router go down) even router doesnt restart, and I have 2 fiber links from 2 different ISPs that cannot go down at the same time and many times. It happened to me many times, all teh LEDs are ON, I have to restart the router to solve this problem. Is there any permanent solution to this problem
