Folks...

I have 2 ISP and an setwork setup as indicated on the attached pic. I am having trouble with choose between them by swaping cable every time i need to use them on certain device. I would need help to set this up in a way that i can choose the ISP of a choice to connect at any point.

Hardware i have with me are as follows

1 ADSL Modem DLink (1 Ethernet port, No WiFi)

2 Zonet Router (4 Ethernet port, 1 WAM port + WiFi)

3 DLink N Router DIR-615 (4 Ethernet port, 1 WAM port + WiFi)

4 DLink 5 Port Switch

Device that go in to this is as follows

2 Desktop PC (Wired)

2 Notebook (Wireless)

1 Smart Phone (Wireless)

1 NAS

All this are on the same ethernet and i keep swapping cables to choose the ISP of choice... but there are time where i would want to use ISP A on Desktop PC 1 and ISP B on Desktop PC 2 while using NAS on both. Need expert opnion on how to set this up...

Can i also use the two routers as a single wireless network ? Currently they are 2 SSID (Everest1 and Everest2)

PS: the two routers are on two different floors

Your network is unnecessarily complex. Flatten the network to just one subnet and then change your default gateway on the computer when you want to switch to the other ISP. You could also invest in a router that can do some of it automatically, but that can be expensive.

I am not too technical .. is there some pictorial representation that you can help me with...

If you have a spare old PC or something, you could look at running a firewall that can manage the link's for you. www.astaro.com is a good start.

I have a old PC ... can i do something about it.. ?

No, I don't have Visio or anything else I can use right now. But I'll explain it simply.

First, turn off DHCP everywhere, you won't need it at the moment.

Now, set your outbound routers to 192.168.1.1 and 192.168.1.2

Set your wireless routers to 192.168.1.10 and 192.168.1.11

Set your computers to 192.168.1.100 and up.

Set your DNS to use Google DNS at 8.8.8.8 to make life easier.

Set your default gateway on the computers to whatever ISP you want to use at the moment, either 192.168.1.1 or 192.168.1.2

That's it, no extra hardware. It's not pretty, but it works.

Now, if you want to get fancy, you can turn off NAT on your outbound routers and put a multi port router in-between them (this is where a spare computer could do a good job if you don't have the budget to use a stand alone router, but remember, you're running a whole computer for something simple like routing, it's a waste of electricity).

I now understand. I dont want to a Computer on all the time.. i will choose the other option.

what would be the default ISP selected ? and is all of this set with static IP ? no DHCP server on ?

How can i use the wireless network on Smart Phone ?

I have gone over this like 20 times I think.. Too lazy to dig it up the thread, maybe in the morning.

But here is the one of the many drawings I have put up on how to do this

If you turn off DHCP it just makes it easier to configure for a small network, but if you want, you can turn on DHCP on one router only. If you only have 4 clients, you can easily do it without DHCP . All you have to do is change the default gateway to point to the ISP you want to use, so if you want to use ISP A, you would use 192.168.1.1 if you want to use ISB B, you would use 192.168.1.2. Same goes for the phone.
