D-Link Wifi

The past few days I’ve been toying with Wifi equipment from D-Link – and access point (DWL-G700AP) and a wireless router (DI-524). These were pretty much the first to wifi-devices, which I’ve completely setup, and configured on my own, so it was an interesting experience. The first experience was in the weekend, when I tried to get a basic TDC Broadband (DSL) connection made avaiable wirelessly. Not knowing too much about Wifi, I though the Access Point was the thing to get, and the DWL-G700AP seemed to be a fair deal in the local IT-vendor. After spending a few hours trying to get it to work, I gave up and called a friend for some advice.
