At the moment I have 2 WLANs on 2 buildings 40-50 meters apart. Then there is 3rd building almost in between these having no WLAN at the moment.
See rough sketch about building location.
On building A there is a DSL modem A-link RR24 and D-link DIR-615 wireless WLAN station(Wireless Router). There is only 1 client on this "huge" network, laptop with D-link DWA-140 USB wireless connectivity device/adapter.
On building B there is A-link RR-24AP (i+) modem/router/WLAN station. There is also only 1 client pc and modem is located on place of letter uppercase 'B' in my sophisticated map :-)
Modem placement is fixed, I would have put it in a place of 'R' but the wires came impractical and onto the way...
About signal carrying tests on aforementioned environment:
When testing DIR-615 in n-mode the signal from building A carried like the line L is drawn, just outside the brickhouse B. Measurement was done by walking with laptop equipped DWA-140.
No signal inside --> test failed.
Then tested coverage of A-link RR-24 in g-mode inside B and it covered at least most of the building. However not carrying long outside the building measured with laptops b/g internal WLAN adapter.
Now I am planning to throw away RR-24 modem and get rid of DSL connection in A. Instead internet should be available by using connection shared from B by RR-24 AP(i+). Because this device only supports b/g mode the g is preferred and N is not used. I feel N-mode did not deliver the promises of extended range anyway.
Finally on to the questions: What is preferred way to implement sharing of B's internet connection to A and B WLANs? Would it be possible to use BRIDGE MODE with TP-Link's TL-WA501G 54Mbps Wireless Access Point (http://www.tp-link.com/products/product_des.asp?id=36
This device would be cheap, but will it work together with these other devices A-link RR-24AP (i+) and D-link Dir-615 ? Will I need 1 or 2 of these Tp-links to create bridge between these 2 WLANS? Traps and pitfalls on these ideas, feel free to tell if I have totally misunderstood something!!!!
I also know that something similar could be done with Access Points with WDS, but I am not sure if wanting to buy any more hardware. I am not sure if WDS works ok with these existing devices.
And what about repeaters, it seems they are not that great but could be simple to setup??
I must say that I am totelly overwhelmed with complexity of this "easy wireless technology" as I thought it should be nowadays.
