Solved network traffic usage question

Specs: Windows 7, 4gb
first off an overview of my setup. we have one cable line going to a four port cable modem which we are grandfathered with 4 static ips. service is 5.0 Mbps / 0.75 Mbps.

i have one port/static ip going to a network for my accounting, parts lookup, ordering, and checking emails network (i am not running an email server). port 2 goes to a netgear wnr2000 router and i put a different ip on this network and it is used for wifi access for employees with smartphones.

1. some employees are streaming pandora on the wifi (port 2) network which is fine but i just wanted to know when is too many people streaming pandora off their smartphones 5, 10, 25?

2. since they are on different ips/routers does one networks bandwidth/usage effect the speed of the other network since they are running off one cable modem?

3. since the two networks are on different ips are they totally separate from each other even if they run off the same modem?

here are the stats from the router last month which i am guessing are over totals over
30 days/average per day.

accounting: download/avg 21,035 / 701.18
upload/avg 1,830/61.00

wifi network: download/avg 1755 / 58.51
upload/avg 159.80 / 5.33

✔ Best Answer
1) When all the bandwidth is used up to the point where nobody has decent connectivity anymore.

2) The simple response is, yes, every user affects every other user. Think about it this way. You have a single pipe coming in that you are splitting up. At some point all the separate connections aggregate and go back into the single pipe. Therefore, every user affects every other user regardless of which network they're on.

3) This is a little tougher to give a definitive answer to. I suspect your 4 static IP's are all within the same subnet and are therefore not really separate. But from the sounds of it, internally, you have them separated.

I suspect the network connected to the SOHO Router has the IP as provided by your ISP configured on the WAN (external/internal) port and you are probably using the router's built in DHCP router to provide TCP/IP settings to clients connecting to it. If this is true, clients on that network have no direct route locall to the other network. But, they may possibly have a route through your ISP's network.

You may be able to test from the management interface of the netgear router. It should have a feature to allow you to ping the other static IP you're using. If you can, and do the ping test, and the static IP from your accounting LAN replies, then you have communication between the two. Alternatively, you could call your ISP and ask them about this.

On a side note, I hope you're using a SOHO router on the account network as well. One can't be too careful, especially with sensitive information you don't want outsiders accessing.

i am using a soho router on the accounting network also.

thanks for the answers especially about if they are separate or not.

Since you have a SOHO router on both sides, they're probably separated because each router should be set (by default) to disallow remote connections.
