See here (http://forums.dlink.com/index.php?topic=848.0) for a post regarding the 130Mbps throughput between Intel 4965AGN and DIR-655. In a nutshell, it appears that the 4965AGN requires a dual-band (5.0 GHz/2.4 GHz) access point to achieve 300Mbps throughput.
Regarding the DIR-655/DWA-552 setup. I have this setup at home. Windows is reporting 300Mbps on my DWA-552 machine when connecting to my DIR-655 router.
DIR-655 setup:
- Firmware: v1.10
- 802.11 mode: Mixed 802.11n and 802.11g
- Enable Auto channel scan: True
- Transmission rate: Best (automatic)
- Channel width: Auto 20/40 MHz
- Visibility status: Invisible
- Security: WPA2-Personal, WPA2 only, AES
DWA-522 setup:
- Windows Vista Home Premium, 32-bit
- Older Socket 478 Pentium 4/875P custom-built PC
- I had constant system lock-up issues with the D-Link Vista drivers for the DWA-552. I installed the latest 32-bit Windows XP drivers for the Atheros 5008 (v6.0.3.94) and I've been stable for weeks with Vista reporting 300Mbps.
- All driver parms are default.
