Mixed Mode doesn't work?

    A friend of mine is in town visiting, bringing along her notebook with a built-in B wireless Orinocco card.

    I change my router to Mixed Mode so her notebook can connect and check her work email, but her card can "see" the SSID (broadcasting), but the wireless stays disconnected. Enabling CTS Protection Mode makes no difference. At the end I have to change to B-only in order to get her notebook online - all my G clients have to reconnect at 11Mbps.

    What is wrong with Mixed Mode? [​IMG] I plan to upgrade my Pocket PC to a wireless model soon, which only has 802.11b, but I would like to keep my G devices connected at the higher speeds. Right now, I don't see I have a choice but to switch everything to B-only in order to get everything to work at the same time [​IMG]

    Maybe this is related to the firmware you are using. My WRT54G 1.1 with the official 1.42.2 Firmware is running in mixed mode without any problems. Both, 802.11b and 802.11g devices can connect to the router. Of course the performance of the 802.11g devices in mixed mode is worse than in g-only mode. But they are definitely running at higher speeds than 11 MBit/s.
    But of course this could be a specific problem of the 802.11b card in your friends notebook, too. Did you already try to connect with other 802.11b cards/devices to your WRT54G, when running in mixed mode?

    Thanks for the tip.

    Unfortunately, I've had the router for over a year and this is the 1st time ever that I have a B device connecting to my router, and I doubt I will have another B device to test with in the foreseeable future, unless I get that PPC PDA.

    Got exactly the same problem. The wireless NIC (b-type) of my IBM T30 ThinkPad does not connect when the mode is set to "Mixed".

    When I set it to b-only it instantly connects.

    I just installed firmware v4.20.7, Aug. 18, 2005 and it did nor solve the problem. Very sad and dissapointing.

    You guys need Long Preamble, CTS Protection Enable, and the rest of the advanced wireless settings on factory default.

    Try HyperWRT. While based on the latest Linksys firmware, most of the Linksys-inspired bugs have been fixed. My "B" device now connects with no problem--in Mixed mode. Don't miss the forums at hyperwrt.org for even more information.

    What are you doing for security anyway? If you don't have WPA or Radius, then you're probably giving away Internet (Movies, Porn, Music, Software) to your neighbor's kids.
