I've been doing some troubleshooting of the Wireless Client Modes (Wireless Client and Wireless Ethernet Bridge) in the MIPS version(s) of FreshTomato. I've posted on a couple of other threads, and to keep from taking over another thread, it's time to start my own. I'm working with a small group of Asus RT-AC66U routers, all of which have been running one version or another of Tomato for several years. I'd like to figure out what's going on with the encrypted modes for Wireless Client (and by extension Wireless Ethernet Bridge) modes. I'm currently working with the latest release of Fresh Tomato (2009.1) since the glitch seems to behave the same way at least as far back as Shibby v.131. I think we can operate under the assumption that the code base is stable -- at least for the MIPS routers. To reproduce the issue: Start with a fresh firmware flash, with a through NVRAM clearing, followed by a soft-reset (to bring the 5G radio back to life). Then configure the WAN in Wireless Client Mode, under DHCP to your upstream access point. Start with an unencrypted link (as a proof of basic functionality). If the unencrypted link works (e.g. you get an address and can pass traffic), move to a WEP encrypted mode. Again, you should be able to get an IP and pass traffic. The problem shows up (for me) when I move to a WPA/WPA2 encrypted link. As best I can tell, the physical link is not occurring at all. This makes me think that there's either a problem with the wireless driver (a blob of precompiled code from Broadcom) or a problem with the way we're passing the crypto information to the physical layer (maybe something we can fix on this end). What I need at this point is feedback about which MIPS routers will and will not make the various connections. I'll be using this thread to post my findings as I go through the various versions and equipment that will and won't work, hoping to find the differences. So far I can positively say that the RT-AC66U will link up in unencrypted client and WEP client, but will not link up with WPA/WPA2 encryption enabled. It *will* receive clients in all three modes though. More to come. Your input is more than welcome!
