To me this Voip Internet Accelerator Intelligent Packet Priority Engine does not live up to the proclaimed capabilities. I have the same problem as an internet technology guy who usses skype, vonage an routers etc, I have lots of uploads and downloads going on and this device no matter what I do I just dont see the great benefit. There is no solid indicator of what it is doing for me differently so I find it hard to recommend since I dont see a difference. There could be a benefit but I will never know what causes the slow down or not because no indicators of I am working as I am suppose to or better or worst because of the Voip Internet Accelerator Intelligent Packet Priority Engine

I was having problems with Vonage when I was downloading anything. I got one of these, plugged it in between my router and my cable modem and basically those problems all went away. Easy as that.
Its not magic. If you have a poor network connection, then thats what you have, but it helped me be able to use my Vonage VoIP without worrying what was being downloaded at that moment.

This device does exactly what it says it will do and with zero configuration. I just plugged it in between my router and cable modem and it went to work prioritizing my outbound traffic. It has been doing this quietly for several months without complaint.
It is important to understand what this device can and cant do. It cant do anything to improve a bad connection from your ISP nor can it do anything about inbound traffic. What it does is give priority to outbound VOIP traffic during periods of heavy uploading (e.g. P2P applications). I no longer have to shut down applications that upload a lot of traffic when I am on the phone nor do I have to mess around with QOS settings in aftermarket firmware on my router. This product fixed my problems 100%.

Provides some quality of service on VOIP traffic. At full list it is pretty expensive for the modest improvement it provides. This product is slightly more effective the more PCs you have on your home network, providing the VOIP or like traffic (video streaming) with priority service. This improves the quality of the call mostly at the other persons end. Your voice is slightly less broken due to the way it delivers the VOIP packets. It can make an otherwise bad call OK.

Firstly, this does make VOIP calls more stable, but it causes so many strange browsing problems that I just had to stop using it. I really like the way that this device prioritises traffice, but as I said, too many problems and too little configuration. I am very technical and spent quite a bit of time trying to get this working well and unfortunately, Im just better off without it.
I am on 7000/896 DSL internet.

When I initially came across the D-Link DI-102 (and the Hawking HBB1) I must admit I was skeptical of these "Broadband Internet Accelerators". After a little research, I decided on the DI-102 (based on my previous good experience with D-Link products). Both devices use the same StreamEngine technology from Ubicom.
We switched our home phone over to VOIP a few months ago, and although our ISP has infrastructure which is well optimized for VOIP, the call quality could be patchy when either of the Windows XP PCs in the house was using the shared DSL connection. However, when my wifes used her Apple Mac to FTP files, the VOIP connection was simply unusable. Unlike Windows XP, OS X 10.4 does not support Quality of Service (QoS), so it severely disrupts the VOIP packets.
Once I received the DI-102, I turned off all of my other equipment, plugged in the DI-102 between the DSL modem and telephone VOIP adapter, turned everything back on, thats it....
The device is very easy to install, and once installed it automatically goes to work. Basically it has two Ethernet connectors and a power connector. The built in browser based configuration is also very simple, providing status information for the device and four configuration options (for data rate, connection type, and static I/P information). Automatic data rate detection is already set by default.
We have noticed a substantial improvement in our VOIP call quality (and now even the Apple Mac cant disrupt our calls).
By the way, connecting this device (and any other networking/VOIP devices you own) to an uninterruptible power supply is essential for protection from "power nasties" such as surges, brownouts, etc.).

Ha ha ha. Im a kid. LOL!
Listen,
I bought this device to use with my asterisk server and it appears to do exactly what it should: give higher priority to VoIP (read: SIP and IAX2) traffic and allocate traffic as bandwidth needs change. I hooked up the device, changed my on-hold music to "Harvard Sentences", which are recognized by the ITU as a good method for determining telephone audio quality.
I immediately noticed a difference for the better, After baselining the quality level with full bandwidth, I tried downloading a few demos from Microsoft, and again, it seemed to work marvelously- no discernable packetloss.
This device wont help in all situations- I have two VoIP accounts, one has ping times around 180ms, and another with a ping time around 75ms. The 75ms VoIP had better call quality in virtually all regards, but the 180ms account still showed a few quality issues, that Ive always had.
I noticed in multiple forums that people are having trouble using these types of devices on Comcast. This may be a cable issue, and because your sharing your connection, QoS probably needs to be setup on the head-end. My experience (with DSL) is 180-degrees of what the previous reviewer said.
Im impressed. Compared to some of the more complex packet prioritization/QoS devices out there, this is the easiest to use out-of-the-box. Its truly PnP. It lacks in some aspects- virtually no end user configuration required, but when you stack it against other $1,000 QoS devices, It gets two thumbs up (way up.) It beats getting a dedicated DSL line for asterisk!
Long story short, if your getting a reasonable pingtime, this will enable you to still use a majority of your bandwidth for your browsing, without having voice quality issues.

I have typical residential cable bandwidth - 5Mbps down and 384kbps up. So, whenever I have massive uploads going on or my son is on bittorrent the VoIP quality degrades terrible (testmyvoip.com calls it "As bad as a crummy cell phone call" and they are right). Which is exactly what this device promises to fix. I assumed that it provides QoS, although I was a little irked that it never gave any technical information. It touts easy installation and promises "intelligent prioritization". It was easy to install all right - but it has intelligence of a straight pass-through wire. There was no difference in performance. Either I upload - or I talk.
The configuration screen looks very skimpy, so I decided to call support if there is any parameters that I can configure. I spent 50 minutes on hold (with most annoying advertising in long time), during which Tier 1 operator asked me for model and serial number of my router and cable modem, not to mention this device itself - before telling that I need to talk to "product specialist". By the way - unlike what the web page says - this device is *not* supported 24/7, since product specialists only work 8am-5pm Pacific.
Once I talked to product specialist - he essentially said "dont fool yourself, you wont get any QoS improvements; just return the device". What I am about to do tomorrow.
Shame on you, D-Link!

My work requires periodic sessions of massive downloads and when its working, this device makes good use of my broadband connection. My connection averages about 13 MPS, and the download sessions generally run at 1.5 to 2 MPS. That might not seem like much, but without this unit, the download sessions run at less than half that speed. No one on the network has noticed any erosion in performance during download sessions, so Id say it was a success in that regard.
The problem is that that whenever theres a hiccup in the connection (brownout, router or switch reset, unknown gremlins) the unit does not reset itself, as does the router, the switch and all my other network equipment. It must be manually disconnected, the broadband feed restablished in the router, then manually reconnected. This is not anything that the DLink suport staff seem to be aware of. Nor is it particularly intuitive (or logical for that matter).
If you can live with this and need focused broadband, place the unit in an easily accessible place and go for it.
