My office has a 100mbps fibre internet and we connect all devices to it via a Netgear WNR3500L. I am thinking of subscribing to another 200mbps with another ISP (because the current ISP does not have a higher plan and we're bounded by contract). The 200mbps comes with a Cisco RV220W router.

I am thinking of the following network setup - diagram in the link below. Basically I would like to split my office computers to have separate internet connections.

However, I need the computers to be able to access each other:

  • All laptops must be able to access the printer which is connected via a LAN cable (eg. in the diagram the Dell laptops must be able to print).
  • Similarly all laptops must be able to access the Synology NAS (eg. in the diagram the Lenovo laptops must be able to access the Synology NAS).
  • Laptops should be able to access each other via IP addresses - because some are web developers and they run WAMP. Easier to review developmental sites on their IP addresses (eg. in the diagram the Dell laptops, via their browsers, must be able to access the lenovo laptops via their internal IP address).
  • There're two DHCP routers but each router has MAC filtering to only allow respective group of laptops (this feature is confirmed available).

Questions:

  1. Would this configuration be possible for the above requirements?
  2. Or do I need both routers to use the same SSID?
  3. Or do I need to link the two routers via a LAN cable?
  4. Or do I need one router to be a DHCP while the other router is not?
  5. Or do I need some form of subnet masking?
  6. Or some of the above?

Thanks!

Are both of these in the same physical location? Are you looking to just increase your bandwidth? Are you trying to establish redundancy? –  mawcsco Feb 12 at 17:29
    
Yes these are in the same physical location, and I'm doing this to increase bandwidth. –  Yong Hwee Feb 12 at 18:03
    
I think you're going to need to get a gateway machine that bonds the two Internet connections, and then downstream from the gateway, you can use a single wireless switch (routing could be handled by the gateway machine) . . . I think pfSense will do this? –  ernie Feb 12 at 18:03
    
I don't want to combine the internet connections. I want one set of computers to have the higher bandwidth connection, and another set to have the lower bandwidth connection. –  Yong Hwee Feb 12 at 18:19
    
This is a psuedo-load-balancing strategy, not a bandwidth strategy. You aren't looking to increase overall bandwidth, but to divide your utilization across multiple WAN-links. –  mawcsco Feb 12 at 18:22

Why not just use different gateways for the different pc and laptop groups? There are various ways you could achieve this whilst running only a single lan

Setting up a VPN will help, i think. Having a direct link between the RV220W & WNR3500L and setting up VPNs.

Change

  1. IP of Cisco router to 192.168.2.201

  2. DHCP : 192.168.2.10- 192.168.2.50

  3. NAS IP to 192.168.2.180.

No, the 3500NL has no native support for VPN and this doesn't make any more sense than directly connecting them. –  quadruplebucky Mar 14 at 10:57
