The launch of the 450Mbps segment of the 802.11n specification was sort of backwards. We saw some of the first routers last year in the September – October time frame. Then at CES we got our first glimpse of one of the new 450Mbps wireless adapters. This was the TRENDNet TEW-687GA that we just finished testing. But we are not going to stop there as we have another 450Mbps adapter from TRENDNet in the lab. This one is more PC specific and connects over USB 2.0. You lose the universal appeal that the 687GA had but gain more on portability. So let’s introduce the TRENDNet TEW-684UB 450Mbps Dual Band USB wireless adapter.
When wireless networking was first introduced it was a very cool concept and people bought into it. The problem was that it was also about as slow as dial-up internet was. The good news is that all technologies advance and wireless was non exception. Once the idea caught on we quickly ramped up in speed, but wireless was never quite able to keep up with a wired connection. We saw these connections leap ahead by a factor of 10 while wireless had small incremental speed jumps. All of that changed in 2011 when researchers built up the next specification for wireless speed, 802.11ac. This speed increase more than doubled what wireless was able to do previously. Suddenly wireless was just as fast as a wired connection (in theory). We have a few routers and adapters in the lab and will be taking a look at them. Today we are going to show you the TRENDNet TEW-812DRU AC1750 dual band wireless router.
Since its introduction there has been something of an internal battle with wireless. On the one hand it is very convenient; you just connect to an access point and you have freedom as long as you are inside the network rand. On the other the speed is not always that great and, if the signal is too weak, you can end up dropping packets, files and losing data. Over the years there have been great improvements in wireless speed, but no matter what it has never been able to match the speed of a wired connection. At least it could not until 802.11ac wireless arrived on the scene. This new specification offers a theoretical limit of 1.3Gbps over a 5GHz wireless connection. We have already taken a look at a router and USB 2.0 adapter, now we are going to look at what happens when you put USB 3.0 into the mix with the TRENDNet TEW-805UB adapter.
One of the nice things about the latest generation of the 802.11 wireless specification (802.11n) is that there is a lot of headroom available in it before there is a need to move to a new generation. When 802.11n first hit the market it was limited to around 150Mbps. This was due to quite a few factors, most notable of these was the use of spatial streams (breaking the signal into separate streams and reassembling them in proper order at the far end. Once this was combined with MIMO (Multiple In Multiple Out) things really took off. Now we are hitting the upper edge of the 802.11n spectrum with the 450Mbps routers and adapters. This new line is getting up there and finally pushing the upper limits of what you can do with this latest revision of the 802.11 protocol. We have another one of TRENDNet’s 450Mbps wireless routers in the lab. This time it is the TEW-692GR a 450Mbps concurrent dual band gaming router with a price tag of around $135. So follow along as we find out if this is really worth your time and money.
Home networking is something that everyone knows a little about. Often times what they know is not accurate (to put it nicely). I have heard some of the most bizarre “facts” about home networks, wireless networking and pretty much everything under the sun. We here at DecryptedTech are officially kicking off our networking section with a review of the TRENDNet TEW-687GA; this is a 450Mbps wireless adapter (sort of). We first saw this back at CES when we had our meeting with Zak from TRENDNet. It is a rather large adapter that boasts the full Duplex speed of 450Mbps at a price of $94.99. Let’s take a look at this product and talk a little about wireless networking in general.
In Mid-2011 it was revealed that many Supervisory Control and Data Acquisition (SCADA) devices were visible on the internet with a simple Google search. What was even more terrifying was that many of these devices still had the default username and password set and were visible in the search results. In 2009 someone with the same idea developed a search engine that was able to find connected devices as a service making it easier to find them and… exploit them. In January of 2012 a security flaw was found in the way that many (if not all) connected IP cameras operated. The flaw was originally found in a TRENDNet’s IP camera (a discontinued one) and it was a serious one.
Before DEF CON 22 started we published an article that the EFF (Electronic Frontier Foundation) was going to host a very interesting competition called SOHOplessly broken. This competition was to features a large array of common SOHO (small office home office) routers and put them to the security test. As you might imagine the competition revealed that security is not the primary focus of this segment of the market. In all a total of 15 zero day vulnerabilities were uncovered during the competition in four common routers.
