Hello,
Here my own experience...
I own 2 x DWL2100AP since about 2 years.
Current firmware:
Firmware Version: v2.20eu
http://picasaweb.google.es/lh/photo/CJCAHUVhlMs0izsOebED6g?feat=directlinkI use them to link two rooms in my flat and I have only experienced a little configuration issue:
I was not able at all to change the radio channel in one of these devices (some bug on Firmware??)
They only breakdown I experienced was because of an electrical storm... One of the power adaptors died.
I had an equivalent, 5v, 2A now... And they work perfectly (no line drops, no traffic jams...)
Just one more comments, I've been Help Desk technician for six years working at least one day a week from home.
The closer one to the 'DSL', is wire connected to the ISP router.
The remote extreme there's a 8 ports switch for 2 computers, a Plextor NAS and a PS2.
Also use a laptop VPN tunneling, VoIP inside and outside the VPN and it works smooth.
Please have a look to my configuration (fingers crossed) I hope this will help you.
They work in WDS Bridge AP (As you may see on the image)
