Hi everyone, I have a Asus RT-AC88U which is connected to 90 devices all using 2.4ghz channel.

I have done a load test, and it turns out that the maximum capacity the router could handle is about 40 ongoing connected devices.

 

How do I work around with this intermittent disconnection when my ISP don't know what to suggest for me?

 

I'm looking for ideas that can potentially solve this issue for me.

 

I appreciate if anyone could help.

supports 256 clients it says [incorrect posted spec.  Lose 1 ip address for the router so you have .2 to .255 which is 253 max clients]

How do I know if a wifi equipment is commercial rated?

 

The reason why I got this router is because it has the most performance.

Can you advise me on how to look at the feature sets of a commercial rated router?

Like certain features that gives me a sign that its the router which I'm looking for.

 

The current router I have is on this URL: https://www.asus.com/sg/Networking/RT-AC88U/

I paid a lot for this router too.

 

Thanks a lot !

 

*I'm using a 250mbps plan and if I connect all computers wirelessly in one go, I only get about 15-20 mbps per computer.

The answer is relatively simple you add Wireless Access Points

Your router's wireless cell can only handle so many wifi connections. You need to add additional wireless cells to share the load wirelessly. Adding 2 or 3 additional Wireless Access Points will resolve your issues.

90 clients on one ap is one hefty load!
No wonder you have issues.

If you have money to spare I suggest you contact a company that can help you provision and set up a router and the wifi system.
Making it work optimally requires careful planning and testing.

If you want to try for yourself Ubiquity seems to have good products for a reasonable price.
Also its not impossible to find consultants that are willing to work with their products

I would start off with 1 firewall:
https://www.ubnt.com/unifi-routing/unifi-security-gateway-pro-4/

And then top it off with 3 (possibly 2) accesspoints like these:
https://unifi-hd.ubnt.com/

The firewall contains a controller for the access points making it easy to set up and maintain.


There is a consultant list on the Ubiquity forums where you can ask for help on a project:

Oh.. almost forgot

A POE switch will be handy to have so you only have to run an ethernet cable to each AP

Can I add more access point on my current ASUS RT-AC88U router?

What does this actually do? Do I connect this to the line, and then female out to the router? If AP means router, that means I need additional router to cater to more wireless connectivity if I buy this?

 

Sorry if I sound stupid, I'm not expertise in this and I'm trying to solve this issue for my company and I'm left for dead.

But I totally understand that having more access points will indeed solve this issue. It's a matter of how I'm going to solve this with the lowest cost...

This can be solved very cheaply. It is not as difficult as you may think Windyy91. I can walk you thru it if you'd like?

Your router is just fine Windyy91, You just have too many wireless devices trying to connect to it all at once. It would have been nice if your router supported Power Over Ethernet then you could have used this network layout. https://photos.app.goo.gl/KeW9jSeu9lFzt2232

But since it does not we will make a network layout that supports Power Over Ethernet equipment.
