(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.

Is that the speed calculated from the internet or from your demarc to your desktops?

 

Is that speed calculated through Windows or with a network testing device?

 

Are you using a packet sniffer at all? Check for broadcast issues? Check for collision issues?

Good morning,

 

Is that the speed calculated from the internet or from your demarc to your desktops? I ran speediest.net from my desktop

 

Is that speed calculated through Windows or with a network testing device? My desktop is windows 7 pro

 

Are you using a packet sniffer at all? Check for broadcast issues? Check for collision issues? I just downloaded packet sniffer.  Will check for loops and ip conflict this am.

 

Thank you so much

Good morning Nancy

It could be that that is the download speed you are receiving from your ISP then, your network could be fully capable.

 

Is that speed calculated through Windows or with a network testing device? My desktop is windows 7 pro

If you really want to check your speeds use a device, but you can always software check a local connection speed for a better reading. Here is a list of some tools you could use.
