Thanks Carol. Yes, NAS is definitely a consideration. (Forgot to mention it!) I've just started looking into upgrading -- after spending a couple hours under and behind my desk recovering from the router unexpectedly resetting itself.

Never did find a cause, but I did have my router settings backed up and simply restored it to its previous config. But I wanted to see if I could find what triggered the reset.
I do need to investigate NAS also. Specific equipment recommended?
In looking for a new router I certainly plan to take a hard look at the "n" routers. Sounds like you have done your homework, and I like what I hear from you there. As for Netgear I have an 802.11g Netgear router from about 2 years ago - hated that one! It automatically disconnected from the internet when connected wirelessly every 10 minutes, or after a few minutes of inactivity - though downloading did not stop the disconnects. Tried to turn that off but could not. Netgear support was not quite as helpful then as Linksys. Might have just been a not-so-good model, and support on a bad day! If you have good experience with them I'll assume I just had a bad one.
As for the Gigabit technology, that does sound good, though wiring in a 100+ year old house is not easy, and I would still need wireless capability at times.
Thank you!
Jim
