I decided to buy ASUS Lyra trio mesh system because I previously had a positive experience with ASUS products. Unfortunately, ASUS Lyra trio was very disappointing! This is perhaps the worst pricy mesh system you'd ever find in stores. Not quite sure if the product normally has many bugs or I might be got a defective pack. However, I will list the couple of issues I faced with this product.First of all, each node has a very poor range of coverage in comparing to other devices like Lynksis Velop. So you can only place all nodes very close to each other. I had to connect one node with Ethernet cable, that node turned into a constant green light. I tried to search for all instructions on ASUS website, I didn't find anything explaining what the constant green light means? It only says that when the device has completely booted and connected to the internet it will show a constant cyan color! However, this constant green disappeared later after I had to reset the node and never appeared again. Later, I could see a constant red light that gets change constantly after some ‘blue’ blinking lights to constant cyan then ‘blue’ blinking and constant red .. so on. It doesn’t understand that node is connected to a cable. The node still transmitting WiFi and you can connect to the Internet and local Lan, but when I move to another room that has a Lyra trio node connected with WiFi to the main node, I will lose signal and then get full signal again! So no benefit from the MESH!Another annoying issue is, it takes around 5-10 minutes for each node to boot and after connecting them to the main node through the app, it will be a nightmare if you want to change the location of any added nodes. You will wait until the long boot finish, then even if you see the cyan color, the whole WiFi system will just freeze. You will see full network coverage on your mobile, but will not be able to surf the web or connect to the local network devices. So, the only option there is to reset the node and reconnect it again! through the app as a new node, I see in other mesh brands' ads where you can just unplug your node power, move anywhere in the home and plug it to power easily and you are all good. This is not going to be so easy with ASUS Lyra trio!The last issue is, in my existing network, I use ASUS RT-AC68U router. I have a 50 MB internet connection speed from my ISP coming from a sperate modem that is connected to my RT-AC68U. Using SpeedTest on my iPhone, I get 50 MB internet speed on results with no issues. However, when I first tried the Lyra trio, I removed the RT-AC68U and connected the Lyra trio to my modem so it became my router. When testing with SpeedTest on iPhone, I could only get 30-36 MB of internet speed! So, I had to return back making RT-AC68U as my router, turning-off its Wifi and making Lyra trio working on access point mode. I could then get 50 MB of internet speed in results if I'm very close to the nodes that are connected with Ethernet Cable. If I'm just 14 ft away, the speed will drop to 18-20 MB, even if I'm very close to the second node that is wirelessly connected to the main node.**Update** Just forgot to mention the issues with the appHad to mention this issues too! The Lyra app is another nightmare! The map of nodes keeps changing when you don’t change anything and sometimes showing unexplained signs. On the other hand, when I change the place of one node, the change doesn’t appear on the map !! There are also many bugs as it takes very long time to show the list of connected devices at the bottom and in many times the buttons to edit or remove for all/some nodes just disappear! It also sometimes doesn’t allow you to type using the keyboard if you want to change the name of a node, no matter where you touch. When you are connecting a new node, after choosing the name of a node, a message saying “Operation failed” appears. You then need to choose the name again and re-click the button to work.
