Summary: I upgraded to the latest firmware as soon as I got this unit. I was impressed with the features especially the VPN. I set that up and connected with my iPhone no prob! You also get a free account with Asus's DDNS service which was great. Unfortunately, the router kept wanting to change my username and/or password - I'd have to reset it which made we have to set the entire router up each time.
Pros: Price VPN Featureset precludes necessity third party firmware DDNS free through asus Did I mention Featureset?
Summary: These are great if you just need to add more ports or for testing things, but don't use them for anything you'd consider mission critical.
Pros: cheap & durable in harsh environments (crawlspace/attic)
Cons: These fail under a heavy load. I bought three of these, one for management and two for iSCSI. Testing iSCSI I was getting throughput of around 70MB/s. On the management side while on IPsec VPN, I was continually getting disconnects. Power cycling the switch helped, but the problem returned shortly thereafter. Replacing the switch with a spare 10/100 fixed the problem.
Summary: I havent had the trouble that a few of the other reviewers have had. Other than a few power outages in the building, the device has been constantly powered, and has never dropped a connection. Great switch at a great cost.
Cons: When doing sustained transfers of large amounts of data (hundreds of gigabytes), the switch drops all network connections (all link lights go dark) and will not work until power cycled. The area where I have it is well ventilated, so heat should not be in issue unless the device has inadequate cooling. I can't recommend a switch that randomly stops switching.
Pros: First one of these I bought works like a charm. It was cheap but has worked perfect. Tech support answered all my questions.
Cons: I bought a second one and it was defective out of the box. It powered on but No link lights. I'm getting a rplacement sent to me. Since the first one works so good, I'm giving them another chance.
