I had recently a boring task (it took me away from some cool clipart work) to configure a hotspot with 3 Access Points put in WDS mode to increase the area covered. It was very consuming as they have to be put in large a building with thick walls and my experience in the area was not that great.
Skipping the useless details (about how it worked well with 2 APs and bad with 3 APs and how all the documentation talks only about using 2 APs), I didn't find anything useful in the manufacturer (D-Link) Knowledge Base, so I used the contact form on the support website to ask for advice.
The reply was quick, but totally useless, with 3 advices:
- - turn off security; Why would a sane person leave the wireless network open?
- - change the channel number; I may try this, but I see no point: the hotspot is in the middle of nowhere, with nothing to produce interferences;
- - and the most useless one: they recommend the demo of a Windows-only software which "simplifies Microsoft Networking and may allow you to trouble shoot your network on your own" (emphasis mine). Duh! The contact form asked for the OS (info not needed for setting up an AP with a web interface) and I specified Linux and I don't need there Windows file and printer sharing
