WiFi in seperate VLAN

    Hello everyone.

    Im having issues with my WiFi connection (as posted here). I think a possible reason could be the wrong configuration of the 2nd VLAN. So i am looking for another tutorial to do this, maybe it will work then.

    What I want to do is to set the WiFi PCs into a seperate VLAN. They shouldnt be able to communicate to the wired PCs, and also not to the other wireless PCs.
    I know that there are several tutorials on VLANs on this forum, but I don't know what would be the right one for me. Can you tell me that?

    I'd be very very thankful..!

    Have you considered using Tomato VLAN-GUI? I've been doing most of my testing/development on a WRT54GL v1.1, just like yours :)
    Currently, VLAN-GUI v8 allows you to create up to 4 LAN bridges via web admin interface, configure isolation/access between each LAN bridge, etc... There's a (non-exhaustive) list of features and (known) limitations here:

    You can have a look at some screenshots from v5 here:

    I can't say for sure this firmware will be able to solve those problematic random wifi disconnects... but it could make life easier when changing/experimenting new settings :)

    Anyways - if you don't like it, you can always revert back to your current firmware image, right?

    Cheers!

    Thanks for your answer!
    I assue i should get the latest one: "Tomato ND VPN MultiLAN VLAN GUI v8 (no SDHC module on this one, sorry)" here: http://code.google.com/p/tomato-sdhc-vlan/downloads/list But what does no SDHC mean? do i need that?

    I took a look at this picture: http://tomato-sdhc-vlan.googlecode.com/files/tomato-vlan-gui-advanced-vlan.png
    but how would i set a seperate VLAN for wifi?

    "no SDHC module" means: this image does not include the kernel module and admin pages on the web interface for the SD/MMC mod.
    See http://gemini.net.pl/~slodki/tomato-sdhc.html and the initial/front page of the project http://code.google.com/p/tomato-sdhc-vlan/

    This firmware image was built/compiled with a WRT54GL in mind (without any HW mods, such as the SD/SDHC/MMC mod mentioned above) and should work just fine on similar hardware, such as the WRT54G v1-v4 and similar models (I've been running this same image in one of my routers):
    http://tomato-sdhc-vlan.googlecode.com/files/tomato-ND-vlan-1.28.8754-VPN-MultiLAN-v8.7z

    Since it seems you've been running some custom scripts, I'd suggest you have any custom settings disabled before starting to prevent any strange/unexpected behavior (backup your settings first, just in case you want to revert the whole thing). Here's some quick'n'dirty instructions:

    After flashing this image, head on to Basic -> Network. In that page, setup 2 LAN bridges: each with it's own IP/netmask and DHCP ranges (change any settings you might need on the primary LAN/br0, create/configure a new bridge: LAN1/br1). Once you're done, save those settings.

    Next, go to Advanced -> VLAN, setup your new VLAN, re-assign ethernet ports on the router (as necessary), link/bridge this new VLAN to that 2nd LAN bridge you just created and change any other settings you might require. Once you're done, hit the save button and the router should reboot. After rebooting, you should have different/separate LANs, ready to be used :)

    Please notice: LAN bridges are isolated/unreachable from/to each other by default. If you want to allow network traffic between any two LAN bridges, go to Advanced -> LAN Access and you'll be able to configure that.

    Cheers!

    Thank you for the information. It seems like my "original" tomato firmware works again, but i will consider moving to this modded tomato when i have problems again.
