I have a Netgear N300 WiFi Range Extender
whose Ethernet port I use to connect my desktop to my network.
I want to use the extender for other things so I bought a D-Link Wireless N300 PCI Express Desktop Adapter
for the desktop.
However, I am getting way lower speeds with the adapter (5-10 Mbps) than I was with the extender (30-35 Mbps).
Even connecting to the extender's wireless network with the adapter yields higher speeds (20-25 Mbps).
I have found that repositioning the adapter's antennas increases speed but only to an extent.
Is the wireless adapter really that inferior to the extender?
Is there anything I can do to remedy this? Or should I just return the adapter and buy a second extender.
