Query: These hubs have a problem!

If you are using just a single hub you probably won't have any problems.If you plan on daisy-chainging them together, you will run into an issue where the hubs must be reset every week or so. They will initially work but then, without any reason, the link between them will quit working. We had Netgear 200+ hubs and found this problem in nearly all of them.Netgear support was of no help either. Since there was no way of reproducing the problem, they took the stance that there was no problem!
