5ghz wireless ethernet bridge, 2.4ghz access point

    Does anyone have experience using a 5ghz network in wireless ethernet bridge mode and using the 2.4ghz network as an access point at the same time?

    Theoretically it seems like it should work....

    Works with WDS. Never got it to work in WET with dd-wrt or Tomato, but it's been at least a year or two since I tried it.

    Depends on the router. I believe the E3000 couldn't operate the two radios in different modes at once, but my Belkin F7D8301 definitely can (though I used it the other way around, since 5ghz has much worse range).

    Decided to use one router in wireless ethernet bridge mode and a second router next to it as an access point (therefore bypassing the issue).

    If anyone tests the original theory please do let us all know how it turns out.

    " E3000 couldn't operate the two radios in different modes at once"

    I did it with an E3000. Worked just fine. BUT I too did WDS. I found that more reliable and easier to maintain.

    The routers talked to each other on 5ghz and clients connected either wired or via 2.4ghz. Wired to the slave, the E3000, worked great.

    I have 2 Asus RT-N66Us running in this configuration:
    * Primary router
    - Shibby build 119 AIO
    - static IP
    - DHCP enabled:
    - 2.4GHz enabled as AP, N only, 40Mhz, WEP2 Personal+AES
    - 5GHz enabled as AP (different SSID), N only, 40MHz, WEP2 Personal+AES;
    - 5+ static DHCPs (desktops, printer, PAP, SAN, etc.)​

    * Secondary router
    - Shibby build 120 VPN with AC drivers
    - DHCP disabled
    - 2.4GHz disabled
    - 5GHz set to Wireless Ethernet Bridge, Auto, WEP2 Personal+AES
    - 5GHz uses the same SSID and password as the primary router
    - DNS: (primary router's IP)
    - DHCP: (primary router's IP)
    - Gateway: (primary router's IP)
    - Advanced:Routing:Mode: Router
    - No static DHCPs (uses the primary router)​

    Note: There is no need to use 40MHz for the bridge - actually 20MHz might work better, but I don't have time to experiment more with the setup for now. The reason I set it up with 40MHz was that I had an old setup where it worked this way and initially I kept the old secondary router while I was playing with the new one.

    Hope this helps.

    Two E4200 with WET bridge and TomatoRAF v1.28.9014 MIPSR2-RAF-v1.3f, I also confirm No static DHCPs for the second router (uses the primary router) or only wired to the router if necessary.

    That is awesome that this setup works! It's really cool to see the screenshots showing it in action. Unfortunately only a 2.4 ghz network reaches (distance wise) where the second router needs to go. So didn't have a choice. Had to use one router to pick up the network on the 2.4 ghz band and a second next to it to act as 2.4 ghz access point. Don't like solely using a 5ghz access point as some devices don't support it (plus the range is a lot less than 2.4 ghz).

    That being said 5 ghz rocks in congested (wifi) areas! 2.4ghz is uselss when there are 50+ networks in range in downtown Los Angeles and Chicago.

    Wanted to give an update encase someone else is thinking about using the following setup. Set up a WRT 54GL in wireless ethernet bridge mode via 2.4ghz wireless G. Got speeds of approximately 20+ MB down and 2 MB up (normal internet speed) when connected to the WRT 54GL via ethernet cable.

    Connected a second router (RT N16) to the WRT 54GL with a ethernet cable. Started using this machine as an access point using a separately named 2.4 ghz SSID. Speeds when connected to the SSID broadcasted by the RT N16 were about 1 MB down and 1 MB up. Connected a device to the RT N16 via cat5 and got approximately 15 MB down and 2 MB up.

    As a result cannot recommend connecting a second router to a router in wireless ethernet bridge mode. mmosoll can you comment on the speed of devices connect to your secondary router? I know that your setup is slightly different.

    *Also very smart/sneaky of this forum to put affiliate links whenever someone types a product name...I changed the spelling (WRT 54Gl versus WRT54GL) of the products referenced above to get rid of the affiliate links.

    I cannot access physically to the routers but I did the following test in both E4200 from a ssh terminal (test file of 100MB):
    wget -O /dev/null http://speedtest.wdc01.softlayer.com/downloads/test100.zip

    The real time graph result from first router (access to WAN):

    And same test from second router with Wireless Ethernet bridge (WL):

    If you are using a wired bridge it is much better to use different channels for the different SSIDs on 2.4GHz. Also, it is a good idea to survey the WiFi networks around you and to choose the two of channels 1, 6 and 11 which have no or the least interference.

    Hope this helps.

    P.S. RE: the affiliate links. This is a way for the forum owners to cover some of the cost of maintaining the site and I personally support it.
