My two DNS-343s exhibit a typical performance of ~10-14 Mbps. Every few weeks, the throughput degrades to ~4.3 Mbps on my Windows 7 box, while the throughput maintains ~10-14 mbps on my XP boxes.
Rebooting the Windows 7 box fixed the problem, until it recurs again a few weeks later.
When this issue occurs, the throughput between the Windows 7 box and other devices on the network are not impacted (and work at optimal levels). Rebooting the DNS-343s and router have no impact. The Windows 7 box is on a wired port.
Does anyone know the cause of this issue?
