A:AnswerBoth are the same 6E wireless protocol and speeds. The 5300 model has three 1-giga ports, while the 5400 model has two 1-giga port and one 2.5 giga port. If you are setting up a full wireless mesh, then really no difference. However, if you plan to link each mesh unit with ethernet wiring, the 2.5 giga port can give better speeds as the backhauling will be done on a 2.5 giga port vs 1 giga port connection.
A:AnswerYour metal barn will kill all wireless signals going inside most likely think of it like talking on a cell phone when you get on a elevator. The call will probably drop once the doors close. As somebody had already mentioned running a cat6a Ethernet underground cable to your barn would be best and hooking one of the units into that cable for a Ethernet back haul would be best. There are still other factors that you need to consider before attempting. For instance If the cat6a cable length exceeds 100 meters it will not work.
Your best bet is to YouTube what others have done to bring wifi service into a barn from their home as distance is going to play a huge factor into the equation. Best of luck.
A:AnswerHi! Yes, you can expand your existing Deco Mesh Wi-Fi System conveniently by introducing additional Deco nodes. All of our Deco Mesh models are compatible with each other; however, to retain the Wi-Fi 6E and 2.5Gbps port (1x per node) features of the Deco XE75 Pro, we recommend building out your Deco XE75 Pro network with the same model.
A:AnswerYES! And it does it automatically. Set all of them up with wireless first. Then simply connect whichever one is near an ethernet jack by wire and within a few moments it will automatically reconfigure to using that as the backchannel. You can mix and match (I have one with ethernet backchannel and one on the 6 GHz backchannel)
A:AnswerHi! That depends on whether your Internet plan and modem support more than 1 Gbps. If your Internet speed is 1 Gbps or less, then you can use any of the 1 Gbps WAN/LAN ports for Internet input, and the 2.5 Gbps port for another device. However, if your Internet speed is greater than 1 Gbps, we recommend using the 2.5 Gbps port for Internet input to better utilize the bandwidth available from your ISP.
