Hi,
If you have a moment, please review my thread in the DNS-323 forum. It may be an issue with my DIR-655 router (QoS or WISH settings?). So I thought I would post here, perhaps a DIR-655 master could help?
Warning: it's a long post, but I did a ton of testing and tried to cover every detail. A couple of posts down I have some thoughts, but need advice.
