    I have more then 30 devices WRT54GS v.1.0 and v.1.1 devices. All was works good with Alchemy pre 6rc1 and GS v.1.0, BUT as we know on GS 1.1 was used another chip and we use firmware based Alchemy versions after rc4 on GS v1.1. AND THE PROBLEMS ARE BEGINING.

    I was tested different versions of devices GS (v.1.0 and v1.1) with all firmware Rc4, Rc5, Rc6, Rc7) including DD-WRT 3.2 and 4 (which is based on Alchemy too) I was try more then 10 devices and now can tell 100% it is bug.

    SOMETHING IS WRONG WITH BOOT UP PROCESS on latest firmware Alchemy and DD-WRT versions. Sometimes, some devices (v.1.1 and v.1.0) do not starting at all. Power led starting quick blinking; DMZ led does not start lighting at all. For decide this problem you must turn on device for some time, and after that start rebooting device by plug and unplug power. After 10-20 times it start working again (it start responding pinging again, and stay work absolutely properly). But after same next rebooting it is stay broken again. The problem more often happening in AP mode, but in client mode it's happening too.

    So. At first I was think - this is a hardware problems, because the best way for repeating this problem (if it happening at once on device) is put it in refrigerator! After stay 20-30 minutes on places with temperature near 0 C you can see this problem yourself again. And on some devices this problem was not occur at all.

    BUT! After same time I did found, that when I am using STANDART LINKSYS firmware or HyperWrt firmware this problems does not occur at all (even on that devices, which was bricked before, and even if your placed device at -5 C). And the problem was found on different parties of devices with different hardware versions.

    Seems. The problem is in the same driver or boot up procedure. May be timeout needed in same place? Unfortunately I cannot test it myself (I don't know Linux). If somebody has this problem - lets discuss it.

    P.S.Little more. Unfortunately my subscription on sveasoft site was terminated after I was publishing info about DD-WRT firmware, which I found on this site. Gays in sveasoft are very serious :) they blocked my account at all. So I can't publish this post where. But if somebody can - tell them about this problem.

    generally i found out that this can happen sometimes. (not often). but this is strong related to the current temperature of the device.
    but please note that the wrt doesnt like very cold temperatures.
    i tested some things in winter on my outdoor installation. after a power-off of several hours it took 45 minutes to get up the wireless connection. if you really get troubles with reboot you just have to plugoff the power for 10 - 20 sec. and plug it on again. this was almost working.
    sometimes also a complete reset of all settings with reconfiguration helps. i never found out why this happend sometimes. but currently it works on my roof without any reboot troubles. so i say. never touch a running system and keep it on. maybe your boot process hangs on a startup process. but i dont know which is it. you find it out you have to plugon a serial console
