Possible to truly "merge" 2 wireless networks .. ?


[link to this post]
 
Hi

I have potentially 2 wireless networks - one running currently from the O2 V box, and another (disabled) network from my Devolo 200 N AV homeplug.

As I understand it, these networks are generated by 2 devices with different MAC addresses. Therefore if both enabled then they show up as 2 separate networks.

If gave them identical SSIDs & WPA2 keys, is there a way to "merge" them to appear as single large network covering my property ?


thanks

in simple terms

if a laptop knows both wifi points it will select the one with the strongest signal

ie - no need to have same ssid or key, probably better to have different ssid then you know which access point you are connected to

i'm not sure what you wish to achieve. you ask?.....

"is there a way to "merge" them to appear as single large network covering my property ?"

it will always be to wifi points, but they will work to give greater coverage. I set my friend up with his sky router as one AP and a devolo home-plug as second AP. As he moves around house his net book just selects strongest signal

The two AP must be on different wireless channels to prevent interference.

So to make two simple appear as one then no is the answer

On 99% of wireless cards...

If you give them the same SSID and same WPA2 key, it will only show as 1 network when you scan.
(provided you are using windows wireless scanner and not a 3rd party one)

It will connect to the one with the most signal (behind the scenes)

It does not differentiate between the 2 MAC's using standard windows wireless scanner or mac osx wireless scanner

I disagree with using different channels...

Just because, if they are both on the same channel it will switch between the two much more seamlessly and smoothly.

Same channel, same SSID, same passphrase, encryption etc - shows up as 1 network when you scan (using windows) on most wireless adaptors

Thanks both

I shall try to re-enable the Devolo & give it identical SSID, WPA2 password & channel and see what happens !

When i have set up AP's with the same ssid/key, the computer still knows it is two access points, perhaps it's the mac? so... if the ssid is "hereiam" i get two profiles on the pc namely "hereiam" and "hereiam 2"

As for using the same channel .. if you are at one extreme of the house or the other yes it'll work, but if you are in a middle area where both AP's are available it can cause problems. It's like Radio 1 and 2 being on the same frequency, which station will you hear on your radio?

It is possible the wifi will still work, but the speeds in this overlap area will be affected. Ask anyone who's neighbour has been on the same channel.

Perhaps you are seeing two networks as they are on different channels (I've not tried this)

I know that some adapters show both but most devices do not
My Sony vaio, iPhone, printer and MacBook pro all only see one network

Also I see your point with the wireless however lately it's not as big of a problem as you make it sound
You are probably always in this situation whereby there's interference & often it's stronger than your wifi

Wifi generally doesn't interfere too badly with one another
I actually find channel 11 best which has my network and next doors

It's more the kind of devices that are a problem
Eg wireless baby monitors, cordless phones, microwaves are much worse and generally use lower channels.
These devices you cannot see but chances are they are interfering much worse than an overlapping wifi signal

I've just done this with an access point and a router that I've set up to be an additional access point.
Same SSID and WPA2 key, different channels.
I only see one SSID name to connect to on my windows laptop and android phone and they seem to choose the strongest signal to connect to.

Yep don't know why the guys seeing two profiles.

Must just be certain adaptors

This is wrong. Its good practise to have two access points that are next to each other on a different non overlapping channel.

In my household I have one router downstairs and a router upstairs (to get the signal all around the house)

With the wireless channels different...

If I connect downstairs and then go to the 3rd floor.
I lose access to the downstairs AP
It does not automatically change to the upstairs AP until I click the wireless icon in the notification area

With the same wireless channel

I connect downstairs. Go upstairs to the 3rd floor
The signal doesn't drop it seems to seemlessly switch over

This occurs on two Sony laptops (both the same)

Bearing in mind with my setup the routers are not side by side

Thats just what happens with your setup and is not neccesarily the rule.. In theory the best practise way to do it is with non overlapping channels. This is what is done in enterprise networks with 100's of access points. In practise though with home level equipment odd things may happen like you experience.

Totally agree with you there.
I had assumed that it was a common thing when it actually doesn't seem to be.
