6/27/19 - Final note - I ended up taking down this system for my house but my house is NOT normal household as I have 40-50 devices at any given moment including 10 google homes, 2 alexa, 10 or so WIFI devices including sprinkler, outlet control, bulbs, door control & alarm system. My guess is TENDA CAN handle up to 30 or so.... and unfortunately adding more nodes does NOT increase this capacity. Main issue I had was that it cannot play music smoothly on google home more than 1 unit at a time. And once that brings down the connection, everything else slows down.... But I think if I just use 3 nodes for PCs, phones & netflix, I believe it would work perfectly fine. I plan on using Tenda system I took down at my office where we only have 10 devices or so total.6/24/19 - Final update unless something goes wrong. I installed 3 extra nodes they sent (6 total) on Friday. It's Monday and i've been running a lot of test including playing music on 10 google homes at once, while 2 alexa is also playing music + doing netflix, file transfer, playing game on PC & ETC. so far it had 2 issues, once yesterday where it wouldn't play on one of the google home... even though it was close to MAIN node... Restarted nodes and it resolved the issue. This morning, song had little lag issue but it restored itself in few seconds. Issue this morning can be ignored and blame internet connection as well.CONCLUSION - This is decent system, about equal to GOOGLE WIFI (the other system I tested) with limit of less than 10 devices per node. Meaning if you get pack of 3, you should be good to about 25-30 devices. Any more than that, you need more nodes, I have about 45 devices. I think getting Tri-Band system might yield better result but you're talking next tier models with higher price tags. I'm happy with this system now that they were willing to send me extra nodes to fix the issue. While slow, I'm impressed that they were willing to send me extra nodes.Update 6/13/19 - Either CS team added someone or saw my review as they started to respond faster, almost 2~3 reply a day. As a solution they sent me a new box of 3 nodes to add to my network, saying that having extra nodes will lighten the workload of each node = provide better service. This should be true although having 6 nodes will make whole network slow down a bit. Either way, this IS a workaround to having more devices, thus I'll be upgrading rating to 3 star based on their slow but willingness to find a solution for the customer.Update 6/2/19 - I no longer recommend this product. This is still not a bad product as BUDGET wifi system with limited number of devices. When I first started last year, I only had about 20 devices. My initial review is true at that point. But I realized once I surpassed 30 devices, it started to have a lot of issues. For those who think 'Who has 30 devices? that's crazy', please keep in mind that each Google Home Mini, Smart Door Lock, Smart Sprinkler, all phones & ipad, & etc count as a device. This device is capable of handling maybe 10~15 device per node.Regardless, if you think you'll never get 25+ devices, this system may still work for you. But if you think you may go above 25, get something else.- Tenda Support is almost non-existent & Amazon will not help. Amazon just says you have to contact manufacturer or bring a denial letter which no I don't see why manufacturer will do. Their support is very slow where they respond to you maybe ever 2~4 days with quick one line response that's repetitive... they won't offer any real solution nor provide real help.- At this point, you CANNOT stream music on google device smoothly and your PC will lose connection randomly here and there then connect again after few seconds... It's very obvious that limit of mesh wifi system has been reached.- Tenda have this thing called Capacity Oriented mode which is meant to turn on when you have 30+ devices. I think they made this BECAUSE they know their system has issue above 25-30 devices. However, when this is one, you'll noticed your printers being disconnected (dropped by router) or your FB message comes in all at once instead of how it normally works... Or your email comes in all at once when you turn off WIFI on your phone. Essentially to 'FIX' their capacity issue, they created a mode that slows traffic until they can catch up = Your devices are dropped or slowed down. This is why I changed my review to 1 start today. And I've been trying to work this out with their support for over a week with one response of one liner...Sorry, that's just not going to do. I'm going to call my loss and installed Google WIFI today and all the problem I mentioned are magically gone. I suggest you do the same if you plan on having 25+ devices. If not, this device may work for you.Update 5/25 - all back to working no thanks to support. You can expect support to respond to you about once a day which similar typical questions or to check a few things that you already did. Didn't really offer you more… thankfully the unit is well made it is functional and I was able to hard reset using different resources I found on the Google no thanks to support that was too slow for my taste. If somebody actually have Network outage, and they had to rely on support, I can't imagine getting proper help within a week. One question a day essentially. I was so fond that QOS on this system is not well designed and it's better to be off as it slows down the whole network once you have enough clients. Would I still recommend this system? Yes, but only if you are tacky enough to be able to figure software issues on your own.UPDATE 5/15/19 - I had some issue with network with internet modem changing, so had to reset the network. System decided to lose the whole network info for some reason. Fine.. not a biggie.. but issue came when I tried to reset 2 other nodes so that it can be added to newly created network using one of the node. It Won't RESET!I'm reducing 2 stars because their 24/7 support means you can submit email 24/7 but they'll respond probably once a day or so... meanwhile, I spent too much time trying to reset this stupid nodes in different ways and it fails each time... I'll revise my review based on support I get & outcome of this issue.------------When we moved here about 3 months ago, I didn't worry about WIFI, afterall I had ASUS top of the line router. It was few years old but still, it was a nice router which performed amazingly in our previously smaller house. At the new house, however, internet port happen to be at a room on 2nd floor... not in the middle area....We've been experiencing some drops & slow connection here and there.. even though we had wifi extender (another ASUS).... it would randomly drop connections....So I did some testing last week to see what's happening and I noticed that signals would get just weak enough to slow down or lose connection briefly dropping everything... So router was dying and it wasn't Spectum's fault like I thought until now...I decided to try this... since it's cheaper than google WIFI and figured what am I do lose, right?Setup & connected in 5 min... and oh man!!! I saw LIGHT & DAY difference. Just with 2 units, one on each floor, I'm getting almost full bar everywhere and this system will let you reach 100MBPS over WIFI no joke! It's amazing!FYI, this has what they call 'capacity oriented mode' which is silly cuz they don't explain what it is. It works by limiting 5Ghz connection to each node to 5... I don't think that really helps that much so i'm leaving mine off... but they are trying to add a lot of new features on each update which is cool.Buy It Now!
