D-Link, an industry leader in networking technology introduces the DI-102 Broadband Internet/VoIP Accelerator, a breakthrough device designed to enhance your VoIP calling experience. Typical Internet applications such as e-mail and chat require minimal bandwidth. But other applications such as Voice over IP (VoIP) and video streaming/conferencing require much higher bandwidth as they are real-time sensitive. The DI-102 Broadband Internet/VoIP Accelerator uses an intelligent engine to detect and prioritize bandwidth-sensitive packets so that they can be sent over the Internet as soon as the request is made. This results in faster processing of real-time based packets, less latency, and a better user experience.

For instance, there are two computers on your network and both are online - one is using an e-mail program and the other is making a VoIP call. When data packets from each computer are sent to the Internet at the same time, the DI-102 will automatically classify the VoIP call as more important and send the VoIP packets first, and the e-mail data second. The user on the phone can immediately notice the benefits whereas the user sending e-mails will barely notice a change.

Setting up the DI-102 only requires 3 easy steps. Power it up, connect your cable or DSL modem to the WAN port and then your router's WAN port to the LAN port. You don’t have to worry about compatibility because this device works with virtually all Internet connection types and broadband routers on the market. In addition, the DI-102 dynamically configures itself by automatically detecting your Internet upload speed and is ready for use once it’s plugged into your existing network infrastructure. It’s a pure plug and play solution! Now, with this Internet/VoIP Accelerator, experience static-free VoIP calls, jitter-free video conferencing, and lag-free online gaming.

5 out of 5 eggsExactly as advertised!

Pros: Perfect QoS with my Vonage Linksys PAP2 that sits behind my Astaro firewall on a Comcast Business Cable connection

Cons: None, I could only see a possible problem being that this thing isn't sold in a high end device. I would pay 10x more for a device like this in some situations if it had a mode for redundancy and guaranteed throughput.

Other Thoughts: I am using this little wonder at my office for our Vonage lines. We use Linksys PAP2 ATAs which are soley telephone adapters without any QoS or networking features. The great part about the PAP2 adapters is that they can sit behind a firewall and function perfectly as long as you have your NAT and packet filtering configured correctly. The downside though is that without QoS you have to control prioritization elsewhere. Enter the D-Link DI-102... it did exactly what I needed. The DI-102 sits between my Comcast Business Cable Internet Gateway and my Astaro Security Linux firewall/router and it is able to perform VoIP packet priortization without changing any structure of my network. You literally just plug this device between your firewall and modem and it just works; no DHCP, no NAT, no fuss. You just have to connect to a little admin page at 192.168.229.61 and then configure a new admin password, upload bandwidth (can be auto-detected), and xDSL or Cable. Done! Just buy one!

5 out of 5 eggsIt Just Works

Pros: It just works, which is pretty amazing, really.

Cons: None I can think of.

Other Thoughts: We have a firewall, behind which sits servers (web, FTP, media), workstations, and Packet-8 VOIP. After spending weeks on various Linux and Windows-based firewall solutions with QOS rules, I just bought this inexpensive product. I put it between the firewall and the DSL model, went to a workstation, connected to its internal web server, set the destination ISP IP address, and ... it just started working. VOIP is much better during downloads. This is the simplest device I've ever used that actually works. Total installation time was 5 minutes. The only thing to note is that you have to have both WAN and LAN plugged in for the internal web page to come up.

3 out of 5 eggs

Pros: This device completely improved my vonage service. I work from home a lot using my company's VPN, and end up on the phone a lot at the same time. Prior to buying this device, my calls were choppy or hollow sounding. The QOS features on my Linksys RT31P2 were useless, and the DI-102 solved this problem with practically no configuration.

Cons: Like one guy said, this thing does have some sort of problem requiring a daily reboot with certain devices. For the first 6 months, it worked flawlessly. Then I swapped out my RT31P2 with a Linksys WRV54G router, and also upgraded my cable modem to a Motorola SB5120. Now I have to cycle the power once a day on my DI-102. I'm sure there's a configuration issue causing this problem, but I'll be darned if I can find anybody with a solution. If you buy this, and this problem happens to you, return it while you still can... Otherwise, enjoy!

2 out of 5 eggsWhen it works, it works well

Pros: When it worked, it prioritized the traffic very well. Very easy to install.

Cons: At least once a day, the device would stop sending most of my traffic requests to my cable modem. My router and computers could be pinged but I could not send out traffic. The only way to fix the problem was to manually login to the device and reboot it. Tech support was of NO HELP, despite the many hours on the phone. They were not aware of the issue, though it is a common issue (from what I found on the internet).

Other Thoughts: My issues might have been caused by incompatibility between my cable modem/router with the D-102

I was unimpressed with D-Link support. Because I thought my D-102 was defective, they informed me the only way to receive a new D-102 was to return it to the store I purchased it from. I will never buy another D-Link product again, awful tech support.

4 out of 5 eggs

Pros: This product does a good job at evaluating QoS and prioritizing packets. You will notice a difference with your VoIP calls while using a lot of bandwidth with other applications.

Cons: This product has locked up on me a few times since I upgraded my cable to the 8meg/768k speed. I'm not sure if it can't handle it or what.

5 out of 5 eggsIt works

Pros: So far this item works very well. I have vonage and before, my calls were really choppy and unclear. but now using this VoIP accelerator they sound great.

Cons: This unit only lays flat. it would've be nice if you could stand it up, but the unit is really small so it doesn't take up to much space. other than that none.

Other Thoughts: Like others have stated if your connection is poor this item will not help.

4 out of 5 eggssuprisingly impressive

Pros: i didn't really expect it to do much and i figured it would probably cause more problems with my link than it helped, but WOW! My voip was practically useless while my sharing software was active. i regularly had to stop using the line to make a voip call. Now I actually make clear calls! And it doesn't seem to effect my speed otherwise.

Cons: there's one little catch, but a fair trade-off. it definately takes longer to initiate a call with this device attaced, but before, without it, i connected faster, but couldn't talk.

Other Thoughts: its not very configurable. it would be nice if you could control which packet types had priority, or maybe even give specific mac addresses priority.

5 out of 5 eggsCool Product

Pros: I bought this to alleviate VOIP quality issues with Vonage. When making a VOIP call I could not use the Internet, because there was no QOS, and calls would get choppy. This does exactly what is advertised, it prioritizes the VOIP packets and all other traffic is secondary. I am now able to use the web, stream audio, video, upload and download massive files, without my VOIP quality suffering.

NOTE: This product will not improve a poor Internet connection, it will only prioritize the packets. So please keep that in mind before dropping cash on this product.

Cons: None that I can think of yet.

Other Thoughts: Product is small and compact and fits easily in place on my desk, in between my cable modem and router. If your Internet connection is poor, you may want to resolve that first, before you get this product.

5 out of 5 eggsIt works!

Pros: On my VOIP phone I was getting audio bounce back, especially when I called a cell phone. This fixed my problem, cleared every thing up. Easy menu setup.

Cons: None

Other Thoughts: Highly recommend this item if you are having priority call or gamer problems. It connects between your cable internet modem and the router.

5 out of 5 eggsGreat Product!

Pros: Removes lag and high latency from your network by using Quality of Service QoS. Easy to setup, zero configuration. Small, size of a deck of playing cards. What this device does is give priority to time sensitive packets like gaming, phone and video conferencing and gives low priority to other packets like e-mail and file transfers so everything runs fast and smooth. Who cares if your e-mail is slightly delayed, but real-time data being delayed like game, phone or video can cause real problems.

Cons: More unsightly wires.

Other Thoughts: I have a 10/1Mbps cable connection and normally, if I try to play a game or make a VoIP call while doing something else like uploading a file, the game would be unplayable and my voice will be broken and garbled to the person I'm talking to. After installing this network optimizer, I can upload files, transfer files over my VPN, play online games, make VoIP calls and use P2P software all at the same time and everything sounds, plays and runs perfect. This is a great product. I highly recommend it to anyone who does allot on the Internet.
