Summary: I have the DWA-130 "E" edition which has no Mac drivers. I tried the DWA-130 "C" edition that has mac drivers (download only--still had the Rev. E hardware) and it didn't work. I just kind of thought or assumed most electrical/USB/etc devices would be compatible with both Windows and Mac. It took me a while to realize that no in fact...such is not the case. I'm a veteran..
Summary: I purchased the refurbished DWA-130/RE version (Pcbay.com Corp. listing). I went to the D-Link website to download the Windows 7 driver. (The CD included with the adapter is bit old with XP and Vista drivers, but no Win 7 driver.) So far, it is working great for me.
Two different versions (C and E) with intermittent disconnects
23 August 2013
Summary: I have two of this product, version C and version E. Both exhibit exactly the same behavior when connected to my dlink router - intermittent disconnects. The two adapters are on totally different machines. Very frustrating, they won't even automatically reconnect. I purchased some no-name USB wireless adapters and discarded the dlink ones with great success. Now my wireless connections stay up with no problem and actually communicate much faster.
Summary: I got this wireless adapter primarily for a computer I was testing with different distributions of Linux. Currently I'm working with the latest LTS version of Ubuntu, and through many hardware changes and stops and starts, it faithfully held a connection to my wireless router on the first floor from within our concrete and cinder block basement. Ubuntu detected it at every startup and quickly connected. The connections were stable throughout many software downloads.
Summary: I have been using this adapter successfully on Ubuntu 8.04 w/NDisWrapper (802.11b/g only) and on Windows Vista 64bit Enterprise (802.11n). The router I am connecting to is an Asus WL500W running DD-WRT in 802.11 n/b/g mixed mode and WPA2-PSK. Although there are several drywalls between the computer and the router I always get >100Mbps which can be considered very reasonable. The connection is stable and reliable.
Pros: - Good reception for a USB adapter, - Comes with useful USB extension cable
Cons: - Software can not install drivers unless the adapter is present at the time of installation.
