Re: hostap_plx to Belkin hardware AP communication does not work?

Hmmm. I was suspecting/dreading this myself. Just as a lark, I went ahead and bought another Belkin to see if I could take out hostap_plx from the equation and see if WDSing 2 Belkin APs might work. Even that did not work. BTW, I also turned on the "standard" WDS code in the driver in the vain hope that my hardware had new enough firmware to support it. Made no difference.

When I looked very carefully in the Belkin manual at the diagram of how "roaming" with multiple Belkin APs worked, I noticed that both APs were HARDWIRED back to the same switch! So I guess what they mean by "extending your network" is that you can hardwire all your APs to your network to extend the wireless range. In my HOME this is not feasible (avoiding hardwiring components was the whole point!).

So I guess I cannot extend my network by having my stations and APs cooperate and bridge me to an AP that is hardwired into my network. And as a corrollary, because the Belkin APs only work if they are all hardwired to a network, this means consumers are incented to purchase VASTLY fewer APs because of the hardwired limitation. I am thinking that Belkin may not be in the home AP business too long :-).

Now the DLink AP in the store had explicitly mentioned AP to AP bridging, so maybe that will work. I will try that next and let people know the results. The Musenki sounds nice...but paying $200 more for an AP seems excessive. If you can get me one of those for $109, then PLEASE send me the link! ;-)
