Incredible dificult wifi setup

by fscussel / July 9, 2013 10:45 AM PDT

What I'm trying to do is:

wifiA(Int signal) <-wireless-> router A <-cable-> router B (AP) <-> Devices

problem is wifiA will vary, so I need router A to have a fixed IP for itself. Router B also needs fixed IP, cause I need to get in A setup to connect to other networks. If it has dinamyc IP it's hard to know what the ip is.

biggest problem is that since I will connect to different wifi's the subnet could be 192.168.1.XXX, 192.168.0.XXX, 192.168.5.XXX

so router A would be connected to a for example, while in the same time I need it to have an ip of for itself. How to do that?

also I am confused on how to configure both routers in the following fields:

Operation mode: bridge or NAT DHCP client, server, off subnet mask IP of each router (does it have to be in a range? I'm using for A and for B)

also, how should I interconnect both routers, in 1 to 4 router A linking to Internet port router B? or both in the 1-4 ports?

As this would require two internet IP addresses and incur double the fees (US and Canada, I can't speak for the rest of the world) I wonder why this odd setup was designed.

I'd return any funds to the client as they are not going to be happy.

In parting I've done the more usual

Cable modem -> Router -> Devices and second router as a WAP

And I don't consider that difficult or as expensive as what you are trying to do.

it's necessary to do so, because I interact with plenty of wifi signals, so one router would work as the horse, messing with all the IP translations, and the other is the one the devices will connect to so to receive internet signal. another way to do it would be wireless repeater mode. it's ALMOST the same. but not the same. since I must connect to different wifi signals, the wireless repeater would be too much troble, cause all the devices connected would change their ip's when I connect to another wifi signal.

My setup is not a wireless repeater.

It's a WAP. Very different.

But since you want this, you'll have to pony up the payments to get your second router working (another internet IP from the ISP.)

This ain't cheap.
