Question: Can I connect this switch directly to my DSL modem; and then 2 computers, a roku box, and router to the switch (downstream from it) so I can turn off wireless most of the time?
Document: Plug and play, worked right out of the box with no issues. This unit is the primary switch that is connected directly to my DSL router and from which 2 TrendNet Gigabit switches in other areas of the house connect. This one does seem about 1.5 times faster than the TrendNet ones. I have not setup and do not use jumbo frames. The throughput on Gigabit seems only limited to the hardware I am using, maxing out at 52 MBps per windows explorer.
This is a very attractive switch that I am using for Gigabit speeds with Cat6 cabling. It is small and provides 7 connections plus the uplink (which for me is port 1). If you do not need the uplink, that port can serve as your eigth connection.I used to transfer files and do backups across my wireless network. I have recently rearranged my basement and placed all of my computers near my cable modem and wireless router.
This is an awesome switch, it's so fast that you cannot perceive there's a switch on your network. My setup is: Comcast cable modem - {Apple time capsule(router) connected to a HP home server} - Dlink switch - Computers, printers Etc. I have transfer speeds of 89-95 Mbps with peaks of 140 Mbps. My comcast cable gives me ~3.5Mbps downloads with peaks of 5.3 but dropping to the 3 range. To me this is very fast and impressive.
We had a Dlink router and of course it has 4 ports. Problem is (I don't like wireless for stuff like streaming) we have 2 Blu-ray players, 1 xbox 360, 2 computers, and a tivo. That's 6 connections there, and there will probably be more in the future. I purchased this, it has 8 ports plus you can still use 3 from the router, so right now we have a capability to hook up 11 items to the network.
I bought this switch to add several computers to my home network. These additional computers will just be folding for the Stanford University Folding@Home distributed computing project, so I wanted to turn off the wireless cards and add them to the wired network. This switch works great! It was truly plug-and-play. I set up the additional computers and had them networked in about 10 min. I paid $35 from Amazon, which is $10 cheaper than my local Fry's.
I have certainly stretched this product to the limit. With a blu ray player, xbox, playstation three, wii, two laptops and roku box I have never noticed a drop in internet speed. Quick to respond to multiple signals, as well as knowing when to turn off certain ports, this 8-port system works great and I hope to use it for the next couple of years.
This item is what it says "Plug n Play", all i did was connect my cables and turn it on i was all set and readyI use this item for 2 xbox's and 1 computer, it is always working and i have have had no problems yet.
Bought for daughter for Halls Room Ethernet Connection to internet. D-Link picked up internet settings automatically straight off and though the idea was to connect various kit/computer through switch as no wireless allowed/supported in rooms - next thing I knew she had connected D-Link to Apple Time Capsule and was running a wireless network! Does the job!
One of the best experiences I've had with a tech purchase. I just wanted to write a review for people like me that don't really have a clue about switches, routers, modems, etc... I needed more inputs then provided by my router/modem. I have DSL from AT&T and my entertainment area was expanding so I needed more inputs. I thought this D-Link unit might work for that and guess what it did!
I have a wireless printer and a PC in my home office, along with a multitude of WiFi devices throughout the house. I have a WiFi extender in the office (the router is in a more central room in the house), but the extender only has one Ethernet port. This switch allows me to connect both the PC and the printer to our home WiFi. Set-up was as simple as plugging in the Ethernet cords.
Answer: Yes, you should be able to do this, although I am not sure you've got the correct order of connection, it should be, DSL Modem > Router> switch > Devices... I have my PS3,AppleTV,Yamaha Receiver, and DirecTv connected to this switch, and the switch itself to my router and my router connected to my ISP Modem. it provides a much better and stable connection for improved streaming.
