Hello there,

I would like to bring wi-fi from building A to B.
They are physically separated (300 meters), but they are under the same network thanks to a radio channel.

At now, building A is equipped with a Netagear D6300 Modem Router WiFi.
D6300 spreads two wireless networks, standard and guest (for guests access only).
For your convenience I'm going to call the standard one "office-wifi" and the guest one "guest-wifi"

At now, while in the building B, I'm able to surf the net only by wire.
So, I would like to bring the wi-fi to building B, possibly the same wireless networks as in building A, it means "office-wifi" and "guest-wifi", so all the connected devices are under the same wireless networks, as if they were in building A.
So, I'm just wondering if what above is possible by placing an access point in the building B set in bridge mode in order to have a kind of extended wi-fi.

If so, could you suggest a suitable AP, that can also grant access to the most common mobile devices (iOS, Android, Windows Mobile) ?

Thanks a lot.
S.

Oh, I did not realize the wired connection you spoke about in building B was coming from building A. So yes, that is much simpler as you have already "bridged" the two buildings together with a wire. Now all you have to do is put an AP in building B to distribute wireless. It is best to make sure it is on a different channel from building A. If you are using the 2.4ghz band then make sure you only use channels 1,6, or 11. If you want you can use the same SSID and password as the wireless in building A (or you can use different, your choice).
Now about the guest network. There are 2 ways to do it. One way is to create VLANs. This involves having switches that are manageable as well as having a little bit of networking...

At 300 meters trying to pick up Wifi that was transmitted inside one structure to the inside of another structure is not going to work well even with high gain antennas. If you want to share the signal like that the best way would be to use a wireless bridge between the two buildings and then put a WAP in the building where you want Wifi. You will need a clear line of site between buildings. On the side that currently has wifi you would mount the bridge on the outside of the building facing the other building. You would wire it back to your router with an ethernet cable. At the other building you would mount the bridge device on the outside of the building facing the other one. You would then wire it back into the building to a WAP that would then distribute the signal.
Just curious, why not just add a WAP to the wired internet connection you already have in building B?
Here is an example of a bride device: http://www.amazon.com/Ubiquiti-US-FCC-NSLOCOM5-NanoStation-loco/dp/B004EHSV4W/ref=sr_1_1?s=electronics&ie=UTF8&qid=1409062730&sr=1-1&keywords=loco+m5
A simple AP to distribute signal: http://www.amazon.com/dp/B00LV0YPFE/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=ESH21VESZ1JF&coliid=I1SJPK44XRGN1F#cm_cr_dpwidget

Hi abailey, first of all thanks for the tip. Now everything is more clear to me.

I’m not very familiar with networking, so I thought was possible to pick-up the wi-fi from the cables (quite weird) because I thought that since the rounter is a wifi one it could deliver the wifi signal through the cables (even more weird). I didn’t realize that the wireless signal is a thing and the wired one is another. By answering your question, I tought it was possible to bring the wifi from A to B through the wires...actually I wanted to do what you suggested without knowing it.

So now, if I add a WAP to the wired internet connection coming (via bridge) from A to B, it means that I need to set the WAP in root mode and I have to configure a new wireless network?

So totally I’ll have 2 wireless networks, one in A (spread by D6300) and one in B (spread by a WAP). Correct?

If so, can a WAP spread guest-wifi, so the connected devices can only have internet access and not any access to shared disks?

Thanks a lot.
S.

Now about the guest network. There are 2 ways to do it. One way is to create VLANs. This involves having switches that are manageable as well as having a little bit of networking knowledge. Another way is that certain AP's have this feature built in. I know there are quite a few that do this but the one I am familiar with is the Ubiquiti AP's (I have one set up in my house doing just like you want to do). It can keep the guest traffic seperate from the other traffic, even using the same network (Vlan and subnet). There are several models, here is a link to a basic one:

Sorry for the confusion. I wrongly assumed the two buildings were not connected in any manner (wired or wireless). Thus I was giving you a way to connect the two buildings without running a wire.
