I’ve got two new Wi-Fi adapters from D-Link that are recommended for use with the DIR-655. One is a PCI card (DWA-552) and the other is a PC Card for a notebook (DWA-652). Both are based on an Atheros chipset, the same as is installed in the DIR-655.
I also had a Wi-Fi adapter for notebooks, Linksys WPC300N, based on an Atheros chipset as well. This gave me the opportunity to perform a compatibility check of Wi-Fi equipment from different manufacturers. I didn’t include the Linksys WRT300N router into this review for the reasons that will be explained shortly. I just want to remind you that this router’s ports are Fast Ethernet only.
Here is a list of equipment and software I used for the tests:
- Two Category 5 Ethernet cables
- Intel Centrino notebook
- Linksys WPC300N PC Card
- D-Link DWA-652 PC Card
- D-Link DWA-552 PCI adapter
- PC based on a mainboard with an integrated Gigabit Ethernet controller
- IxChariot’s High_Performance_Throughput and Throughput (where marked explicitly) scenarios
I tested the DIR-655’s wired interface first. The router’s speed on the local network is indicative of its peak bandwidth.
The three following tests show the bandwidth on the WAN port. The first two tests were performed when the router’s services were disabled, but I enabled QoS, firewall and inbound filter for the third test. The second test was performed with enabled DMZ.
It’s hard to evaluate the results without having any point of reference, yet the numbers look good to me, especially the small reduction of the channel bandwidth under load.
