This is correct. SSIDs must match AND all security/encryption settings must be exactly the same.
Please do note that while these devices are in this configuration all throughput is effectively halved - the devices only operate in half duplex wireless mode.
In otherwords, you will not be seeing 100% of your possible speed... more like 50% and under to be exact. This is not ideal for file sharing on a LAN. Only do it if you must and the negative impact on throughput doesn't matter.
Cheers! Let me know how that helps!
