In my house I have two floors in which I have: - Upstairs a linksys WAG320N connected to Internet - A Netgear R8000 on the ground floor

Now the two wifi networks comunicate because I set the linksys as an access point. But what I would like to get is a 'unique' WiFi network, is it possible?

  • I don't think anybody has any idea what you mean by "unique". – David Schwartz Jun 23 '16 at 22:16
  • If you mean you want the same SSID to be shared across both wireless routers, you will need a technology such as WDS (which needs to be supported by the routers you are using) to make the two networks a single large wireless network. WDS almost always requires that you use matching hardware, at least at the manufacturer level if not the model as well. – Richie086 Jun 23 '16 at 22:23

    Thanks Richie, I didn't know about SSID. If you write as an answer I confirm that – Fabrizio Jun 23 '16 at 22:29

In order to connect the two wireless access points together to extend your network range, you will need to purchase hardware that supports what is known as WDS (Wireless Distribution System) or a similar technology. A wireless distribution system (WDS) is a system enabling the wireless interconnection of access points in an IEEE 802.11 network. It allows a wireless network to be expanded using multiple access points without the traditional requirement for a wired backbone to link them. The notable advantage of WDS over other solutions is that it preserves the MAC addresses of client frames across links between access points.

An access point can be either a main, relay, or remote base station.

A main base station is typically connected to the (wired) Ethernet. A relay base station relays data between remote base stations, wireless clients, or other relay stations; to either a main, or another relay base station.

A remote base station accepts connections from wireless clients and passes them on to relay stations or to main stations. Connections between "clients" are made using MAC addresses.

All base stations in a wireless distribution system must be configured to use the same radio channel, method of encryption (none, WEP, WPA or WPA2) and the same encryption keys. They may be configured to different service set identifiers (SSIDs). WDS also requires every base station to be configured to forward to others in the system.

WDS may also be considered a repeater mode because it appears to bridge and accept wireless clients at the same time (unlike traditional bridging). However, with the repeater method, throughput is halved for all clients connected wirelessly. This is because wifi is an inherently half duplex medium and therefore any wifi device functioning as a repeater must use the Store and forward method of communication.

WDS may be incompatible between different products (even occasionally from the same vendor) since the IEEE 802.11-1999 standard does not define how to construct any such implementations or how stations interact to arrange for exchanging frames of this format. The IEEE 802.11-1999 standard merely defines the 4-address frame format that makes it possible.

When I mentioned SSID in my comment, what WDS provides is a way for you to have the same SSID (aka the name of your wireless network as seen from any wireless client) across multiple access points. I've seen WDS implemented in small setups like 2 story homes all the way up to entire college/corporate campuses and it works quite well.
