Question: What is the maximum length for an ethernet cable to be connected to this switch? Is 50ft too long?
Document: There is an existing ethernet cable 100 ft long (way too long, but it was there and I don't know how the cut it and add a new connector.) running from the modem to the room with the TV and BD player. I connected that cable to my laptop and got no improvement in download speeds. Still in the teens for the most part. I connected that cable to the TRENDnet box and attached the TV, the BD player and my laptop to the TRENDnet.
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.
Well, it is a switch so you just connect the ethernet cables and the power cable and that is it. I used it to allow more wired connections to my remote access point (set up in a Client/Bridge mode). I connected items such as the access point, xbox360 and my directv receiver to it. No problems.
Just about everything wants a connection now. I have a plasma TV, cable box, PS3, and home theater receiver that all take ethernet for internet connections and apps. I prefer a wired connected for gaming an video, so I scooped this up. I ran from my uverse box to the switch, and from the switch to a panasonic smart tv, pioneer receiver, and PS3. Plug and play with no issues. Have had it hooked up for a few weeks now and no rebooting or issues.
I needed to plug more things into my network, but only had a router upstairs, and the switch further away in office. This allows me to plug more wired network devices in without running multiple cables at long length.
My videos stream much more smoothly connected to this switch than wirelessly. Very pleased with the device and the price I paid for it. Would recommend it to anyone needing to expand their network at home or the office (as long as you don't need more than 4 more connections).
I have been using Trendnet ethernet switches for a long time, and they have always been dependable. About a month ago I powered down my system to do some dust cleaning. When I powered everything back up, one of my switches bit the dust.. I replace it with this switch. I started losing my network connection to my entertainment center, but was not sure which device was causing the problem.
Five stars for solid construction and speed! I used this switch to have only one long Ethernet wire run from my router to a second home office where I plugged in my tower, blu-ray player and printer with room for more devices to be plugged in to it in the future. I prefer a wired connection when possible and this switch made it a lot easier! It kept my Gigabit router fast because this switch is also Gigabit speed! No negatives and highly recommended!
Soon I was disappointed to find that as long as the computer was connected to that uVerse port, I would often get digital interference (giant pixelation) on the TV shows I was watching or recording in the uVerse set top box. "Uh-oh," I thought, "This probably means the TrendNet router is going to create the same kind of digital interference. The uVerse documentation doesn't mention using the network port as a local internet connection, so maybe it's not really meant to be used that way."
A+. I would purchase this again if I needed another switch. I checked my ISP connection speed with Speedtest.net before and after the switch was connected and there was no significant difference. I now have three computers and a network printer connected to my cable modem via one CAT5 cable.
Answer: 50 feet shouldn't be too long.  In general, about 300 feet is the maximum for an Ethernet cable.
