Model: Archer C6  
Hardware Version: V4
Firmware Version:

Hello everyone,

We have a network where we have one old TP-link router (TL-840N) as Internet gateway router with IP 192.168.0.1/24.

 

We have place total 21 Archer C6 router in network as access point for providing connectivity to our devices on WLAN only.

 

These local devices are more than 250. (not computer/mobiles, but some controller devices)

 

So my plan is to change main Internet router, we can put new Archer C6 router as Internet gateway router with IP configuration 192.168.0.1/255.255.254.0, so that we can have total 510 usable IP addresses (192.168.0.1 to 192.168.1.254).

 

Main concern is that DHCP pool!

Can I configure more than 254 IP addresses in the DHCP pool with the above LAN IP configuration?

 

 

Regards,

Sagar Patel

Archer C6 is a home wireless router and I doubt that it can handle such number of client devices.

I would recommend to get a business grade router for an internet gateway like one of these to play safe.

For sake of the experiment you could by one more Archer C6 and configure as the internet gateway.

If that doesn't work for you, get one of the business routers mentioned and you'll have one more Archer C6 as an AP.

Hello,

Our aim that our 250 devices should get IP addresses from the DHCP pool.

These 250 devices won't generate any Internet traffic. They all will send data to an application running on one computer in network.

 

We have 250 controller devices, 21 access point and 10 computers, so that we have to configure subnet of 512 IP addresses.

I understand your point and I've seen a 23-bit netmask used in home routers LAN settings, but I'm not sure if that will work for you - I've never tested this:

 

 

Setting 23-bit netmask is allowed:

  @terziyski Namaste,

I tried this on Archer C6 version 4 router. 
 

I changed mask to 255.255.254.0

and configured DHCP pool from 192.168.0.2 to 192.168.1.200. 
 

I saved this and did not give an error.! 
 

 

Regards,

So far so good. Now you have to check whether the C6 can offer IP addresses from its 192.168.1.0/24 subent to your client devices.

In order to check that you can use the DHCP address reservation feature of C6 - details.

I checked that in different way.

I joined one wireless device and assigned manual IP in the range of 192.168.1.X and other devices were joined ang recevied IP addresses from DHCP pool.

 

I checked communication between the devices on 192.168.0.X and 192.168.1.X.

Devices on the both the subnets were communicating.

 

Then, Should I check the DHCP reservation?

 

Regards,

Sagar Patel

I would test that as well, because with your test you just test connectivity, but not the C6 DHCP server. This should be a quick test - after all that's your decision.
