Need help with spliting up ISP ip addresses to groups of computers.

I have 5 static Ip's from my ISP. Currently I have the gateway in bridge mode, unmanaged switch, 5 routers(one static ip from ISP to each), switch for each router, then 7 computers for each switch.

Switches are 8port tplink unmanaged gigabit
Routers are tplink gigabit routers

The setup works ok but it isn't rock solid.
The only goal of this setup is to achieve an internet connection using several different ISP IP addresses for groups of computers.

The issue I am having is that when 35 users are surfing the web heavily, I start to get a slowdown. The ISP said I needed to increase my internet speed. I did. I went from 100 to 150. There was almost no improvement if any.

This told me that something is holding me back. When all of the computers are needing data from the internet at the same time there is a bottleneck. I think it could be the gateway itself (comcast) even though it's in bridge mode or possibly the first switch. I don't have much networking knowledge so I started with this setup. It does work, but I think it could work better. I'd like a better solution so that user aren't experiencing slow downs waiting for webpages when usage times on this network are high. I'd like to be able to take advantage of the faster internet speed and add more end users and ip addresses. I should be able to add more to my network with the jump in speed from 100-150 if things were working right in my opinion.

You can use a single router and run just a couple users and they can eat 150m if they are doing stupid stuff.

You only have 3-4m per user when you have 35 active. That is not a real lot when you look at how graphic intensive many web pages are. Many even have embedded video that eats even more.

I suspect you problem is purely not enough bandwidth. If you saw difference between the groups of users on the different routers then maybe you could adjust something but when it affects everyone there is not much left and a device in bridge mode is extremely simplistic so it will not bottleneck you.

Now you could have some strange issue with your internet connection that it gets lots of errors when the data rate is high.

If possible...

If possible you need to find a way to see how much bandwidth you are really using. If you are using the max then the problem occurs then it is bandwidth otherwise you can ask the ISP why it does not go to maximum.

What's the router load look like? Is it keeping up with the bandwidth and connections? You could monitor your pings. Maybe some traffic shaping or an AQM could help keep your pings low under load. High pings are the number one reasons for the Internet "feeling slow".
 


Do you have enterprise service from the ISP with the proper hardware or are you using home user equipment? The issue may be the gateway or routers, possibly internal network. If those users are online with watching videos, you need a pretty robust setup.
