None. While I have great success with such hardware, none seem to work out of the box for me. I always have to update FIRMWARE and Drivers.
This can be a strain on consumers and they may need to have such done for them.
I recently purchased and very quickly returned a Netgear MR814 wireless router and two MA111 USB network adapters because of serious problems. To make a long story short, Netgear tech help was absolutely non-existant: I got disconnected every time I made a telephone call (after spending considerable time navigating their menu) and never got responses through e-mail tech support. I am not a computer novice but networking is a complicated issue, yet since wireless networks are becoming as essential as my microwave or cell phone I am not ready to give up. Is there a company--Linksys, Belkin, or whoever--that actually holds up the "24x7" tech support listed on the box?--I mean, I am willing to pay more to ensure that tech support exists so I can keep a simple home network (two PCs and a DSL connection) running. I would very much appreciate any comments.
