Wireless Client Insecure, Virtual Wireless Secure, does it work?

    Hello, I am trying to configure a WRT54GL with Toastman 7634 to connect to a public wifi that has no encryption and want to create a 2nd virtual access point but enable encryption to at least encrypt the LAN traffic between devices connected to the virtual access point. It does not seem to work. It allows me to proceed with the configuration but the Mac laptop times out when attempting to connect to the virtual access point. Wireless Client is only capable on wl0 and Access Point is the only choice on wl0.1 so I can't swap them.

    If I remove encryption from wl0.1 so they are both unencrypted, the laptop connects as expected and can reach the internet. I tried almost every possible encryption scheme but none seems to work.

    Is this what you are experiencing as well? I tried doing the same with Shibby 114 but the router would crash when I tried to save the virtual wireless config.

    Would have a router with both a 2.4 and a 5GHz radio help? I do have an RT-N16 but have not tried it since I would have to take it out of service.

    Thanks for your time.

    Bump to see if anyone has attempted a similar scenario with different results.

    I faced a similar problem. Could anyone help using a detailed guidance?

    Device - Asus RT-N12. Firmware - Tomato-K26-1.28.RT-N5x-MIPSR2-123-Max.

    Task: to get internet using “Client” mode and to share it for the other devices using “Access Point” mode with DHCP after. My configuration you can learn here:


    Advanced->Virtual Wireless:

    The problem is that my configuration doesn’t work stably. I can obtain an IP from AP but only for a short period of time and only during the first connection. The second connection is always denied. Sometimes I can connect my router using sometimes no.

    Where is my mistake?

    Thank you in advance.

    To be honest, it's not something I've tried before, so I can't speak from experience. But if I had to guess, I'm willing to bet it's a limitation of the wireless chipset. Think about all you're asking it to do; support three wireless connections (one physical, two virtual), with different encryption requirements, all on a single radio. Frankly, I find it amazing you can reconfigure these things as a wireless client and add even a single VAP, never mind two of them! No matter how amazing it may be, invariably you find a point beyond which you can’t push it any further. It certainly wouldn’t surprise me if that was the case. That’s why (as the OP suggests) this is better solved using a second radio (integrated or external). If I get the chance, I’ll take a closer look, but I just have a strong feeling this isn’t a limitation of tomato, but just the chipset.

    Thanks for your reply Eibgrad.

    I am sure your idea about chipset limitation has a sense. It works unpredictably every single time. Either the router loses a connection with a provider or my smartphone loses a connection with AP. The same thing is about the duration of the connection. For example, when I tried using AP without encryption it worked about 10 minutes properly. Then I set up WPA2 method and the device couldn’t even connect to the provider.

    This is why I need someone to check my configuration attentively in order to make me sure that it is not the fault of my settings but the matter of the chipset.
