Style Name:Plastic Housing| Size Name:5 Port|Verified Purchase
For any Get Smart fans out there this product is hard to believe.
I was upstairs and my router was downstairs.
I was not able to string 3 50' cables to each of my computers.
Well I could but my wife wouldn't let me :)
This gives you hard cable speed with only one cable coming up from the basement
So now I have 4 units...PS3, Windows, Linux and a storage box all hard wired.

5.0 out of 5 stars Just works, never have to touch it! Feb. 28 2011
By J. Blair - Published on
Style Name:Metal Housing|Size Name:16 Port
I upgraded from an 8 port Gigabit Trendnet switch to this bad boy with 16 ports. I've got 15/16 used up and it's never let me down. I can easily get transfer speeds between my two gigabit desktops of around 90-110 MB/s (using 7200RPM and SSD Hard Drives#.

All I had to do was plug in my ethernet cables, turn the power on and haven't touched it since. Reliable and fast connection for all the devices on my home network.

No fan inside, it doesn't run hot even in a wall box and it's completely silent.

LED's on the front will tell you if a device is connected and if it's Green it's connected at Gigabit and Amber if it's 10/100.

Very satisfied with the purchase and would recommend to anyone looking to venture to the Gigabit realm. FYI you will need Gigabit ethernet cards on the computers that you want to connect to the network to get Gigabit speeds #125MB/s vs 12.5MB/s on 10/100# so don't expect your 3-4 year old Desktop to connect at gigabit speeds. But don't fret, gigabit NIC's are pretty cheap, I got this low profile #for slim computers# Dynex - Gigabit PCI Desktop Adapter DX-PCIGB used for about $6 on Amazon #3rd party seller#, but you can just search "Gigabit ethernet card" and find them new for around $10-$15 new with full size bracket# Make sure it says Gigabit or 10/100/1000 in the title though as Gigabit is for some reason a key word on some 10/100 cards#

If you're wondering what you'll gain from going gigabit, here's a brief overview of bits and Bytes and 10/100 vs 10/100/1000 #gigabit#:

MB = Mega Bytes, Mb = Mega Bits. 8 bits in 1 Byte

You have a 100 MB file. If you transfer at 100 Mb/s it will download in 12.5 seconds.

If you have a 100 MB file and you transfer it at 100 MB/s, it will transfer in 1 second.

If your Internet provider says you can download at speeds up to 8 Mb/s. That means you can download 1 MB in 1 second.

If your Internet provider says you can download at speeds up to 16 Mb/s. That means you can download 2 MB in 1 second.

Transfer speed on a 10/100 router would be up to 12.5 MB/s.

Transfer speed on a 10/100/1000 #gigabit# router would be up to 125 MB/s.

Say you have a DVD rip that is 2.5GB, on a hard wire connection between 2 gigabit computers it would take roughly 20 seconds to transfer. On a 10/100 connection it would take about 3 minutes and 20 seconds.

Say you have a 1080p MKV video file that is 32GB, on a hard wire connection between 2 gigabit computers it would take roughly 4 minutes and 16 seconds to transfer. On a 10/100 connection it would take about 42 minutes and 40 seconds.

Note: These are theoretical speeds and much depends on your processing speed and also your hard drive speed.

If you have any questions just comment, I get automatic e-mail notifications on comments and will answer questions as quickly as possible.


Update 03/01/2012:

It's been a year now since it's been installed and left in the wall. Never had an issue with it this whole time, even with power outages, lighting strikes #killed my Xbox#, it has been rock solid. Still highly recommended.


Update 04/13/2013:

Another year and still no issues. I took it out of the wall when I moved and now it's located on a shelf in my laundry room which can get quite humid when the dryer runs and still running like a champ.

5.0 out of 5 stars Solid performance in my home network March 20 2011
By Paul Gifford - Published on
Style Name:Metal Housing| Size Name:5 Port|Verified Purchase
I bought two of these TRENDnet switches (a 5 port and an 8 port) when I upgraded our home network from 100 Mbps to 1 Gbps speed. I'm very happy with their performance and stability. I haven't had to think of them once since connecting them to the network. Both switches are connected to a D-Link DIR-655 Router: one with 100 feet of CAT-6 cable and the other with 25 feet.

This switch isn't very large - about the size of a paperback book. I've uploaded a picture to the product page to give you an idea of its relative size. The measurement from our Kill A Watt meter agrees with what others have already noted; this switch uses very little power. The lights on the front are helpful: green indicates a 1 Gbps connection while amber means a 100 Mbps connection.

To get a measure of speed through the switch I copied a 26 GB file between two computers connected to the same switch using drag and drop in Windows Explorer. Average speed for the transfer was 102 MB/sec. That was before enabling jumbo frames on the source and target computers.

This router supports jumbo frames up to 9216 bytes. In real world performance I achieved best performance with the computers configured for 4k frames. Between two Windows 7 64-bit computers I averaged 114 MB/sec tranferring the 26 GB file. Between a Windows 7 computer and a Windows Home Server (version 1) I averaged 109 MB/sec.

To enable jumbo frame support in Windows, right-click on Computer and select Manage. Click on Device Manager, open Network Adapters, right-click on your adapter and select Properties. Under the Advanced tab select Jumbo Frame and choose an appropriate value. Note this only applies to wired adapters; wireless connections don't support jumbo frames.

I've got absolutely no complaints about this switch. It's a great value and perfect for our home network.

5.0 out of 5 stars Compact and very sturdy Sept. 17 2010
By Strohmian - Published on
Style Name:Metal Housing with Internal Power| Size Name:8 Port|Verified Purchase
This is essentially the same model as the TEG-S80G, except it has an internal power supply. One less wall- wart was easily worth the small price premium for me, especially since the metal device looks and feels like it will last until gigabit ethernet becomes obsolete. The five- year warranty suggests longevity as well.

The power cable disconnects and the grounded connector is labeled "100-240V, 50/60Hz", nice pluses these days. The switch remains cool to the touch and draws a frugal 1 Watt, but unfortunately, my Kill-a-Watt also reports 14 VAs! I can see Germany or Switzerland refusing an Eco sticker over that awful power factor, but practically speaking, this is your power company's problem - you only pay for the 1 Watt real load, which for me tallies up to $2, annually.

On the actual networking side, this switch is unspectacular - which is a good thing! I use it like I use a power strip - cable from the router goes on port #1, all else on the next free port. 10Mbit webcam, 100 MBit incoming internet, 1000 MBit NAS - it's all seamless. One thing to note is that the rear ports don't have lights. I happen to find the amber/green lights on some Ethernet ports rather reassuring and professional (like in a data center). On this unit the lights are on the front and only of one color. I admit that's a pet peeve and retain the 5 stars for a super- solid, simple device.

1.0 out of 5 stars Two defective units - randomly stops forwarding: design/firmware flaw? Jan. 3 2012
By Thomas M. Coyle - Published on
Style Name:Metal Housing| Size Name:16 Port|Verified Purchase
In mid-November I ordered one of these for a small-office client to replace a Linksys/Cisco SRW2008 which the office had outgrown. I chose the TEG-S16Dg based on the fact that the office didn't need a managed switch, its excellent price-per-port when compared to other unmanaged switches, and its consistently-positive reviews both here and elsewhere. In this office there are 10 users backed by a Real Server, with consistent high-bandwidth utilization (lots of large document and image manipulation and cataloging). Given that the switch is unmanaged, installation is indeed plug-and-play. My observations were that the performance was on-par with the Cisco, and there were no issues with either Auto or hard-coding speed and duplex on the server, network peripherals, and client machines. All in all, a great box at a great price.

And then the problem started.

One month after installation, after running 24x7 with no issues, the switch just stopped forwarding between certain ports. The links didn't actually go down and there were no other indications of a failure, but random devices just couldn't connect any longer to random other devices. Bounce the switch and all was well for about 10 minutes, and then the problem started again. I say "random" above because there didn't seem to be any consistency about what ports would be affected, except in the case of the server - in all cases, that port would stop forwarding (whichever port it happened to be - I did try a number of different ports) - but otherwise, random devices among all 16 ports would be affected (not even in a particular port bank, which is a common failure mode), and the next failure after reboot would affect different ports, which ports would remain affected until the next boot. An investigation of the server revealed no warnings or issues, and I concluded with changing both the NIC and the cables just for giggles. No effect - same problem.

I order from Amazon primarily because of Prime, their wonderful return policy, and excellent support reps. I received a same-model replacement right away, installed it, sent the bad one back, and, after a couple weeks of solid performance, chalked it up to a one-off bad unit. No such luck. The exact same issue has now occurred with the new unit.

I called TrendNet support. They claim no knowledge or reports of this issue, and given that the switch is unmanaged, there's no user-serviceable action that can be taken, such as a firmware upgrade. Googling also offers no reports of such a problem.

Given that lack of reports, and given the unlikelihood that I've received two bad switches with identical failure modes, my conclusion is that there is a design flaw in the product that can't handle some event that's happening in this environment (though I can correlate no such event with these failures), which Trend missed in their design and QA.

Since this is a consumer- or small-business oriented switch, it's unlikely that most customers will be pushing as much data through it as consistently as my client's environment, so perhaps that's a contributor. Otherwise, the only thing that stands out is Trend's "GREENnet" technology which reduces power utilization per port based primarily on cable length - perhaps there's something unusual in that technology that's having trouble either with my cables (all Cat6 500Mhz both for endpoints and for premise-punchdown with a maximum switch-to-client distance of 12 meters through two punchdowns, and short-run Cat6 500Mhz direct cabling to the server and other gear in the IDF closet itself), some other obscure item like MTU, a problem with heat (there is no dedicated AC in the IDF but the temperature remains constant at about 80F, which should be perfectly fine) or some combination of the above. Either way, given that everything in my architecture is designed correctly, was working perfectly with the SRW2008 24x7 for over a year, and, again, has worked perfectly with each of these Trend switches - until they die in this decidedly-odd fashion - I must conclude that there is a design flaw. While it's possible that I received a pair of bad switches (maybe there was an issue with one batch in manufacturing), TrendNet hasn't acknowledged such an issue. I'm certainly not going to waste any more time trying a third one of these.

For now, I've placed the SRW2008 back in service, chained to a dumb 10/100 switch for a few low-bandwidth endpoints, until I decide on a replacement device. Given Trend's overall-excellent reputation and reviews, I'm willing to give them another chance, but only with a device with a different architecture. The main contender right now is their TEG-160WS, which is managed, does NOT have GREENnet, and is only about $50 more. I'll write an update if I do go with that unit.

*2/13/12 Update: I ended up replacing the TEG-S16Dg with the latest "big brother" of the SRW2008, the Cisco Sg 200-18 18-PORT Gigabit. Despite the much higher price of admission, I wanted the management and monitoring capability (which is absurdly extensive given the target audience of small businesses) and the Cisco reliability to which I'm accustomed from my large datacenter implementations. For once, it seems like a manufacturer managed to integrate an acquisition - Linksys in this case - very well; while this product's origins were as a high-end Linksys and ended up as a low-end Cisco, the throughput, reliability (so far), configuration options, and other various bells and whistles make this switch a relative bargain. Note that it too offers the "green ethernet" option (I hadn't been aware of this initiative and how widespread it's become), but I've disabled it for now (+1 for highly-configurable managed switches); if the switch survives through the end of the month I'll turn it on to see what happens - I haven't yet discounted that there might be something unusual happening in the environment with an IP phone or desktop dumb switch that's causing the low-power / cable length detection to go wonky.

*6/26/12 Update: Except for configuration-change-necessitated reboots, the Cisco has been running 24x7 since I installed it with zero issues. So, unless Trend has finally acknowledged and/or fixed their design flaw, skip this and buy the Cisco.

5.0 out of 5 stars Going strong for a number of months Nov. 29 2011
By W. Shannon - Published on
Style Name:Metal Housing with Internal Power|Size Name:8 Port
At first I was not sure that a cheap switch could do such a good job, (I got mine on sale for around $30). I have had it now for a number of months and have not needed to reset it. Unlike a lot of other switches this one is wall mountable (screws are not included but most standard screws will work) which makes my install look so much better. I was able to get very speed over old beat up cat5e cable, I have recently rewired my house with cat6 but have yet to preform a speed test. I plan on buying another TREND network soon to expand my network.

Somethings to note and explain if people don't know them:

TRENDnet makes two different 8 port Gigabit switches, one with a power supply built in and the other with a power adapter. Both seem to get good reviews and don't seem to have other differences so go with whatever is cheaper at the time you buy. The power adapter one is a 90degree angel one so for most strip plugs it will not take up more than one space.

This is a switch not a router, I have noticed in some reviews some people have left bad reviews because of this. The difference between a switch and router is that a router shares the internet connection with multiple computers and in the case of most home networks assigns the IP addresses. This device is used to expand the network. This device will provide gigabit speeds between devices plugged into it even if the router it is plugged into is not a gigabit router.

The "green" means that it saves energy by only using the power needed on each port. A standard non green switch will send full power out over each port (enough for the max of a 100m cable run) where a green switch like this one will only send out the power needed for the length of the cable.

Gigabit Ethernet "requires" at least Cat5e cable and uses all 4 pares of the cable (as opposed to only 2 with 10/100 Ethernet), you can try it on something else but it may not work right.

This switch is what is known in the IT field as a "dumb" switch, meaning that it is plug and play and there is no configuration necessary, if you don't know the difference between a "dumb" and a "smart" switch it is safe to say that what you need is a "dumb" switch and this is a good choice.

UPDATE ON July 29, 2014
Switch is still running fine. Have not had any issues with it. I have also found out although cheep it has more memory than most name brands(close second to the Netgear prosafe). People have successfully reported this switch working with AT&T Uverse set top boxes.
