Hi there, I'm just upgrading some equipment due to our neighbors polluting the 2.4GHZ in some areas (specifically two routers sending at 1+6 and 5+11 channels in addition to 6 other routers resulting in a really dirty 2.4GHZ band in some locations). I'm looking for: The best High Performance Wifi-Setup for Throughput and High Performance Gaming (= Low Ping at a stable connection) in the N and AC-Band only. The High Performance Device(s) will connect via the Wireless Ethernet Bridge in the 5.8GHZ Band. The 5.8GHZ Band should also be used to link between the Router and Repeater since the 2.4GHZ Band is to polluted in the area (the positions are optimally choosen and switching positions will not do anything other then worsening the situation). The rest of the Clients will be using the 2.4GHZ Connection of the Repeater (due to it being the best position for it - and only needing medium performance throughput). The Main-Router will have QoS enabled and properly Setup (I've read all tutorials and have used it to good success for over 2 years now) to trottle bandwidth dynamically enabling still good pings while watching a stream or downloading a big file. I'm a bit unsure how to arrange my Equipment as of now, so in short I'm looking for advice how to arrage them. As in f. e. AC56U in 2nd Floor as Main-Router, AC66U in 1st Floor as Repeater, N66U as Wireless Ether Bridge in the ground floor. Read below at "My previous Setup". My Environment: 30MBit's Connection via Cable with a Stable Ping between 15-20ms (averaging at 17ms) 9 Wireless-Clients all of them at least at N-Standard with a Throughput of 144 Mbit 's each at least. However only one of them should be used for High Performance Gaming / Maximum Throughput, that is also the one which will get the Wireless Ethernet Bridge this one is sitting at the ground-floor level with 1 wall and a medium wooden ceiling in-between. Big house with medium-thick walls (no steel/concrete) ranging over 3 floors (including the ground-floor) The Modem and Main-Router is in the 2nd floor. It wasn't my choice to do that - but at least it 's enabling quite good WiFi access in the garden/court via the 2.4GHZ band (which hasn't be used at High Performance Speeds. The Equipment I have at hand now: Asus RT-AC66U AC1750 Asus RT-AC56U AC1200 Asus RT-N66U N900 (the only device from my old setup) My previous Setup: Cable-Modem connected via 1GB Ethernet to the Asus RT-N16U acting as Main-Router with QoS enabled and acting as the DHCP-Server in the 2nd floor. The Asus RT-N16U will be replaced by either the N66U or the AC56U. It 's all working in the N-Band only right now. Asus RT-N66U in the 1st floor with almost Airline (not exactly - a bit of the stairs is in the way - wooden that is) connected in Wireless Bridge Mode via the 2.4GHZ Band (since the N16U has only 2.4GHZ that is why I'm replacing it due to the new routers in the neighboorhood). The connection between them is at 20mHz Channel-Width with a signal of 50% at 144MBPS pretty stable but as I said the 2.4GHZ is pretty polluted especially at the area both of those connect so I'm absolutely looking forward to replace that with a more reliable 5.8GHZ connection. The Asus RT-N66U also has a 64GB USB 2.0 Stick attached which is used for the TV and to share movies with different Devices via DLNA. Asus USB-N66 Wireless-Client in the Basement with a wall and a medium tick (more thin then thick) wooden concrete. I'm connected via 5.8GHZ to the RT-N66U with about 56-58 dBi at 144-178 MBits. The Connection to the RT-N66U is pretty stable, so I imagine with a Wireless Ethernet Bridge it should be better even though the USB-N66 is using 3 internal Antennas. How I think I should be arranging the new Setup: Cable-Modem connected via 1GB Ethernet to the Asus RT-AC56U in the 2nd floor. It only has 4 internal Antennas however I read that the AC-Band has far better Wireless Range in the 5.8GHZ Frequency so I guess it 's best to use the 5.8GHZ Band with AC/N Mixed and ... ... connect the Asus RT-AC66U in the 1st floor to it via Wireless Repeater Mode in the AC-Band. This place is the best one for reaching all clients - also my own PC with High Performance needs in terms of a reliable and low Ping and good troughput via the Wireless Ethernet Bridge. All other devices will connect via 2.4GHZ which can now run properly either in the Channel 3 or Channel 9 which are the least polluted in that area, and hasn't to be shared like in my previous Setup also giving the best range for most of the other Clients. This should also enable me to ... ... use the RT-N66U as a Wireless Ethernet Client in the ground-floor. I know that it isn't possible for it to reach the theoretical Speeds of the AC-Routers / Clients being limited to 20mHz only however if it has a stable Connection with a least 180 Mbit/s it should be well enough and not give me a bottleneck - unlike if I use the RT-N66U either as the Repeater or Main-Router since it doesn't have the AC-Band. Yep it 's a long read but in the end ... Let me add that I have about 0% packetloss with my current Setup and a ping from my ground-floor to the LAN-PC at the Main-Router averaging at 2-4ms with a maximum ping of 50ms (which is simply due to the polluted 2.4GHZ connection between the Repeater and the Main-Router). Between the ground-floor and the Repeater I have a maximum ping of 4ms and an average of 1ms. Wew, ok. Quite a read, did I forget anything or am I doing some stupid stuff? I would like to hear your thoughs on if I'm planning my new setup correctly or if I should arrange it differently - or add a station inbetween. Thanks for taking the time to read that Wall of Text! Cheers, Simon. p.s: Shibby, Jacky any everyone working on Tomato - if you ever read that - thank you very much for all the work you do for us! Your stuff ranges far above all other business implementations I've seen and I wouldn't know what to do if it wasn't for you! Edit: Sorry if this isn't the correct Sub-Forum. I though it best fits here since all of them are using Tomato and it 's related to it in good amounts (the complete setup and it 's performance that is).
