Cannot access two wireless AP's simultaneously

Hello Experts,

I have two Asus RT-N13U ver.B1 both running DD-WRT custom firmware (same revision).
I have the routers configured as follows:

- DHCP off
- StaticIP: 192.168.1.10, 192.168.1.11
- MASK: 255.255.255.0
- Unmanaged 8-port desktop switch with only these two devices (LAN ports) and my laptop plugged in

I cannot access them in ANY capacity simultaneously, only one at a time. Whenever I have the two devices plugged in simultaneously and run a continuous PING I can only PING one device at a time. The ping responses will alternate between the two devices but never respond at the same time.

I have tried different subnets, different switches, different ports, different FW. No combination of anything I can do seems to work. There must be something I am missing.

Anyone help?

As far as I know, network connections are always one-to-one, never one-to-many simultaneously.  I know of no reason to think that would ever work.

Hello Dave,
Thanks for responding but I'm not quite sure we are on the same page.
Maybe I did not properly explain myself. I have two wireless access points, only one functions at a time. The moment I plug the second one in all IP traffic ceases on the first one. They seem to conflict with one another.
Each access point must have only 1 unique IP address assigned to it - from your original post it appears you have set up both access points with the same 2 IP addresses - and thus when you plug the second WAP in to the switch there is a conflict.

WAP 1 : 192.168.1.10 / 255.255.255.0
WAP 2 : 192.168.1.11 / 255.255.255.0

As you state that you have installed custom firmware it could also be a that you have other conflicts within your local IP address space.
You have only mentioned one computer.  Do you have other computers connecting wirelessly?  In order to have traffic thru both routers/APs, you would have to have two computers connecting to them and they may have to be on opposite sides of the area to make sure they didn't both connect to the same AP.

In case my original post was not clear the WAP's are configured as you suggested:

WAP 1 : 192.168.1.10 / 255.255.255.0
WAP 2 : 192.168.1.11 / 255.255.255.0

I should also probably mention that I have setup this exact same layout before without any issue.

Dave: I have one computer trying to access both WAP's not necessarily wirelessly but in other ways. IE: I cannot even access the webGUI/SSH/TELNET/PING (you name it). I have tested from multiple workstations.

(one example): I telnet into WAP1 and it connects. I cannot telnet into WAP2. I unplug WAP1 and I can telnet into WAP2. Same goes for PING, webGUI etc...

The WAP's conflict with one another when both plugged into the same switch and only one is reachable through the LAN interface at a time.
