Could it be that the * (data loss??) up there are not due to comcast at all, but internal to my wireless network? I don't really have a clue here about this topic, so just guessing. It's not like the *s always show up against the same IP addresses.
I think the problem might be the combination of this linksys USB stick (811g) and my wireless router (811g+n, apple airport extreme). I tried doing tracert from a mac on the same wireless network, and it was perfectly clean (to the same IP as above). I found a couple PCI cards on newegg that are listed as 811n, I think one was $30 and the other was $50. The wife and kids watch a lot of streaming video on the internal network during the day, so I don't dare downgrade the airport to g-only mode.
Hmm. maybe I could get a second cable modem, there is a cable socket in this room. Not sure how comcast would feel about that. If that was ok, then I could have a wired connection to this pc.
