(21) desktops & server - low bandwith usage - no videos, graphics... Just accounting software. They are on 192.168.5.x and connected to Comcast modem/router.
(5) Open-Mesh Access points. They are on 10.5.10.x. The Comcast wireless is turned off.
(20) 5 megapixel cameras with VMS. They are on 10.6.10.x
(21) IP phones. They are 172.172.172.x
At Comcast modem/router - 151 Mbps down/23 Mbps up
At any of the desktop on the 192.168.5.x, with Cameras & Access Points POWERED down, speed test shows 46 Mbps down/23 Mbps up.
Is it normal that I lose 100+ Mbps within the network?
If this is not normal, should I look for looped (both ends of cable going to the same switch) or IP conflict? What else should I look for?
Thanks for your guidance.
