Hi all.
I'm in the process of setting up internet connection in our horseback riding club.
Due to distance issues we have decided on getting two internet connections.
These are wireless as the ISPs transmitter mast is very close.
We would like to have 2 wireless networks at 2 locations, so both buildings and the surroundings are covered.
Is it possible to set both routers up with the same SSID and different channels and then the users computers, phones etc. will see it as one network ?
Regards
Christian

I'm not really sure if you can put them on the same ssid. The problem I do see is with the DHCP, you can only have one DHCP server on the subnet. The problem is it will only allow you to configure one default gateway, which is the connection all internet traffic will go to. All traffic to the internet will try to go through the gateway which will only be on one of the routers.

Hi, the setup is not quite like that.
There are two different internet connections and one wireless router on each.
And one DHCP on each router
So in other terms, like you and your neighbour :)
What I want is to have the same SSID in both routers so the clients will only need to use one SSID.
Wouldn't the clients get new gateway ip's when going from router #1 to router #2 ?

I have bought two identical TP-Link TL-MR3420 wireless N routers, and they have some WDS functionality.
If I skip one of the internet connections and get lucky and the two routers come to see each other, can this WDS solve my problem ?
Will both routers be accessible via the same SSID ?

Your first plan will work fine. Running 2 different networks on the same SSID is fine when the intended result is to surf the internet. I would run completely different subnets on the lan side. Although the PC SHOULD ask for a new IP when it reconnects to a new router it may not. The proof your plan works is very simple when you look at the number of people who use the factory SSID and run with no security...they all work fine for them..until the hackers get them.

Unless money is a huge issue I would avoid WDS. First there tend to use WPS to set them up which can be cracked and needs to be disabled. The main issue though is the performance. Since all the data is repeated even in a perfect installation you have cut your bandwidth in half. In real world situations a repeater in a already interference prone wireless setup quickly degrades.

Hi, I will start by trying the 2 connections / 2 routers / same SSID and test it.
If there are any problems I will try the WDS option.
The horseback riding club is, as most of them probably are, located in a rural area, and therefore the intentions are running with no security as it will make it much easier for the users.
There aren't that much other wi-fi interference if any.....I will test with Wifi Analyzer.
