Topic: multiple ssid question

The content of this topic has been archived on 14 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hi,

I got a wrt54gl v1.1 running rev. 6181 of this very nice firmware :-)
I am trying out the multiple ssid feature and I can connect but I have some problems

- My WIFI client (intel 2915abg) seems confused often only showing one of the SSIDs: Is this my client having a problem or is it the linksys box :-/
- When I only activate encryption WPA/PSK in one of the SSIDs it also showed the other SSID as being protected. Because of that I activated both with a PSK key. Is this a limitation of the chipset that both SSIDs have to use the same encryption, or do I have to mention "encryption none" or simular?

The AP reports multiple SSIDs, but each has the same BSSID. In other words the mac address of the AP stays the same across all the SSIDs which can confuse the client.

You should still be able to connect to the right SSID but you may have to manually enter it.

Thanks for the quick answer :-)

Is "option bssid" supported on my device (wrt54gl v1.1)? If not, which hardware running openwrt does support this?

/Peter

The BSSID option relates to WDS links, not multiple SSIDs.

Hi,

OK thanks for clarification. My point is that I would like to have seperate networks for public, private, work, my kids ;-)

It is working fine by selecting the SSID manually but it would be nice if they could be made "visible" which different BSSIDs...

Can someone explain if this is a hardware or software limitation?
If it is a hardware limitation which hardware would you recommend?

/Peter

Whats interesting is that putting one SSID in "client Bridge" mode and the other to "AP" mode will not route trafic from Client bridge to AP??? Am I wrong?


config wifi-iface
        option device   wl0
        option mode     sta
        option ssid     someAPweconnected
        option network lan

config wifi-iface
        option device   wl0
        option mode     ap
        option ssid     APwewanttoRepeat
        option network  lan

Is this right?

The discussion might have continued from here.
