I have no idea if anyone will even see this post, but I have blown the dust off a DWA-130 Rev. A1 that I found buried in my office.
I plugged it into my 8.1 Pro 64b system to see what would happen and surprisingly it works. However, even though windows reports a 300Mbps connection to my EA4500 when I run speedtest.net I can't even hit 30Mbps.
I then found a Netgear WNA1100 in the same heap of stuff so I plugged it in to compare. The installation was decidedly more involved, but eventually it also worked. Windows reported a 72Mbps connection to my EA4500, and then I maxed out my 50Mbps ISP on speedtest o.O
So I put the DWA-130 back in and bam, dropped to 30Mbps again ... anyone have any idea why this would be?
The router is about 30 inches away from my usb port, so I don't imagine it's a distance issue :-/
For the record, the WNA1100 is a N150 usb adapter.
I assumed the DWA-130 was a N300 device (given that Window$ showed it connected at that speed, although the D-Link product page for it doesn't actually provide that information. According to this page http://www.geeks.com/details.asp?invtid=DWA-130-PB-R
it is actually a N150 adapter
Also just to clarify, both units are being plugged into the exact same USB2.0 port on the computer. Only one of them is installed at any given time. When I test them, I have the Gb LAN adapter disabled.
