Netgear does have its problems... http://www.dslreports.com/shownews/31774?mode=flat
That said, all the inexpensive devices have problems of one sort or another. I think it's a case of getting what you paid for / caveat emptor. For small networks clients, I always try to get them to buy one step higher quality than they wanted to pay for (since if they understood the ramifications, they wouldn't need me). It rarely works though ... which does tend to lead to repeat business... Annlee Priscilla Oppenheimer wrote: > It sounds like the Netgear Layer 2 802.3 flow control is buggy.
