    Works nicely with TiVo Mini

    Small, light, and works to extend a 100 mbit network connection over my existing coax. Syncing up between the two units was instantaneous, and the lights on the front clearly show when you have proper connections. See 'other thoughts'. Read more

    Will Not Play Well with Digital Cable TV

    The units interfere with shared digital cable TV on the same coax and reduce the connection to under 1 mbps. These are designed to share the coax with Satelight TV. They will not work well with digital cable. Read more

    4 out of 5 eggs Good solution when you don't wish to run ethernet cable

    Pros: Like many, I picked these devices up in a pair while they were on sale. The connection these devices create is solid and reliable. While the description advertises speeds above 100Mbps, this measurement is likely strictly between the two devices. You will not achieve more than 100Mbps at the Ethernet ports, and in real world scenarios, expect to receive less than this.

    My tests indicated a solid 80 to 85Mbps throughput from my computer to another computer on my LAN. This was with the devices connected directly to each other without the use of splitters, and the coax was not attached to the TV service in my environment. I then connected these devices to a splitter into the TV network in my environment, and as expected, connection speeds dropped. In my particular environment, I achieved 20 to 25Mbps sending to another computer on the network, and between 20Mbps to 44Mbps receiving from the other computer. This is probably more than adequate for the average home user, but if you're a die-hard for the fastest speeds possible, this is absolutely no replacement for Gigabit Ethernet cable. My environment has RG-6 coax, and decent quality splitters. Due to the nature of coax and other installations, you can expect your throughput to vary.

    Cons: Trendnet only offers this device with 100Mbps Ethernet ports. This product would be more desirable if given the option to purchase another model with Gigabit ports.

    Bottom Line: A search on the internet reveals the Trendnet TPA-311 devices cannot be used if you wish to extend a DOCSIS cable modem. Actiontec offers MoCA adapters that are suitable for such a configuration. Additionally, Actiontec also offers a Gigabit version similar to Trendnet's device. However, it is more costly, and worse, not sold by Newegg. I would be curious to know how well the Actiontec Gigabit MoCA adapters perform in a real world scenario.

    Overall, the Trendnet TPA-311 is a decent device that will allow anyone to establish a network connection to other devices & machines where running Ethernet cable is difficult, not an option, or whatever the case may be. I will be using these devices to connect my entertainment system devices (Blu-ray player, etc.) to my network as it is next to impossible to install Ethernet cable in the wall where my system is located (I live in a semi-detached house, and this is the "shared" wall that has all sorts of obstacles). I'd purchase this again, and would use them in situations where Ethernet cabling is a pain to run and coax already exists. I would also only connect these to devices that don't require extremely high speeds.

    3 out of 5 eggs No broadcast packets

    Pros: Works for some applications.

    Cons: Doesn't forward broadcast or multicast packets, only unicast ones. This makes protocols like "arp" not work, and makes the device pretty much useless for a business network.

    Bottom Line: Lack of broadcast packet support is a disappointing fatal flaw in what would have otherwise been a great product. I hope Trendnet fixes it in the next version.

    5 out of 5 eggs Works nicely with TiVo Mini

    Pros: Small, light, and works to extend a 100 mbit network connection over my existing coax.

    Syncing up between the two units was instantaneous, and the lights on the front clearly show when you have proper connections.

    See 'other thoughts'.

    Cons: None significant that I can see right now, system has only been deployed for a day.

    Oh, yeah, there was absolutely NO documentation of ANY sort in the boxes (I bought a pair), but the hookup was very obvious. The Trendnet site does have a brief PDF if you need it.

    Bottom Line: I'm using this to extend a LAN connection from one part of my house to another over coax. There is nothing else on the coax (no cable, satellite, etc.). It just happened to be there from an old installation, and I was in no mood to pull CAT5E/6.

    The coax is about 100 feet of at least 35 year old low grade RG-59 most of which has been outside for all that time, and somewhere in the middle there is a 35 year old low end splitter that's been outside in the weather all this time as well. Additionally, there are at least two coax barrels/couplers somewhere in line as well, so really the worst possible scenario for getting a decent signal.

    Nonetheless, I hooked one of these to one end and one to the other, and my TiVo Mini, which is VERY fussy about a clean LAN connection because it's streaming full HD video from another TiVo, works perfectly. I was pleasantly surprised.

    Note that I have NO idea how well this would work if there were other signals like cable or satellite on the coax as well.

    5 out of 5 eggs Works well with ATT Uverse

    Pros: If you have a duplexer thar has "VDSL", "Combined", and "HPNA", this will work on the HPNA spot

    Cons: A bit pricy. They have no competition. :(

    Bottom Line: Works well for me.

    4 out of 5 eggs Respectable speed, long range

    Pros: Long range, easy setup, respectable speed, minimal latency, excellent stability.

    Cons: Price is a bit high, speed limited by the 10/100 ethernet ports, lack of documentation.

    Bottom Line: I got two of these to run a long outdoor network. I unboxed them, and finding no documentation, started googling around. Unfortunately, there simply is no documentation (apart from a sparse datasheet), but thankfully they work without too much trouble. They basically act as a bridge, anything that goes in one side comes out the other. The actual data rate is better than the 10/100 ports on the device, so each device has two ethernet ports. Basically, each ethernet port is connected to the coax line, and to the other port. The intended purpose is probably for two computers to connect to one device. However, in a pinch, you can even use it as a two port hub. I used these to run a network of about a kilometer. I used brand new RG-6 cable, with only a TPA-311 at each end. Even at that distance, the performance was still as good as or better than 100mbit ethernet, and there was no discernable latency.
    I don't know how these perform when run on the same cable as various other signals, but they work great for long wired networks. In my case, the 1km run was entirely outdoors, so if you get direct burial RG-6, it'll be far easier than going with fiber. Also, if you're willing to plunk down the money, you could probably get even better range using good RG-11 cable. I don't think these will handle interconnecting busy networks very well, but for getting internet access through an industrial or agricultural complex where wireless is not an option, they work great.

    5 out of 5 eggs Works great with Uverse!

    Pros: Works great, using it as a HomePNA adapter to get a connection on the other end of the house. Only two devices on the network, the AT&T Uverse Gateway, and this guy. Havent conducted a device-to-device speed test, but it for sure is able to max out my 12Mb/s internet connection, which is all I really need.

    Was very easy to install, plugged everything in and it just worked. Doesnt get much easier than that.

    Cons: None.

    Bottom Line: Its nice that they give you two ethernet ports on the device. For me, that enough to not need a hub, which is awesome. Same thing with the coax-to-tv connection.

    Works great with Uverse internet.

    3 out of 5 eggs Will Not Play Well with Digital Cable TV

    Pros: When these adapters are placed between coax cable without any other sharing i.e. cable TV, the adapters run very well. I was getting the full 100 mbps signal over 200 feet away. These are mid-band adapters that run in the same frequency as digital cable and will not work when cable is installed with the adapters. If you isolate the coax lines and only run the adapters, you will get excellent service. When setup this way however, the coax does not distribute any cable tv or phone service.

    Cons: The units interfere with shared digital cable TV on the same coax and reduce the connection to under 1 mbps. These are designed to share the coax with Satelight TV. They will not work well with digital cable.

    Bottom Line: I had to return these units and once again, newegg's customer service was superb. Thank you for continued support.
