DD-WRT 11779 的一连串问题

glede

我是说怎么出问题了....
还好刷回来了

这个版本无线不稳定，建议使用11785，这个我测了两天了还没断过！速度也不错

那看来我还是幸运的，最起码我还是刷回旧版了。虽然用web无法降级，但是我直接断电然后再开机，就进入了WRH54G的安全刷机模式。具体原因我不明白，但是总算是刷回来了。我刷机一般都是先回复出厂设置，升级之后再按住重启键5秒，我很想知道那个30/30/30大法的具体步骤给内存来个大清理，谁能告诉我？

今天早晨我直接在WEB页面从11779升级到11793，重启两次，没有任何问题，看来所谓升级任何版本都会失败的说法只是个案吧！这个版本有个独特之处，原来我的350N每次升级新版本固件都要重新激活128MB内存，这次升级后还是128MB，其他地方还是一个CPU占用过高的问题，比11779有过之而无不及，达到27%（同样负载 ）

人七十

我的芭比禄升级到11793后，CPU只占用7% ，中继后无线速度比以前任何版本都快了。

如果是向下升级肯定会出什么问题，如果向新的版本升的话，肯定没问题的了。ddwrt的精英们如果不解决这个BUG，那还混个屁啊

Hard Reset (aka 30/30/30 reset):
The following procedure will clear out the NVRAM and set dd-wrt back to default values:

With the unit powered on, press and hold the reset button on back of unit for 30 seconds
Without releasing the reset button, unplug the unit and hold reset for another 30 seconds
Plug the unit back in STILL holding the reset button a final 30 seconds (please note that this step can put Asus devices into recovery mode...see note below!)
This procedure should be done BEFORE and AFTER every firmware upgrade/downgrade.

Do not use configuration restore if you change firmware builds (different svn build numbers).

[NOTE] - For Asus units the standard 30/30/30 method will reset the router but will put it into recovery mode after the final 30 seconds. This is not a problem...but be aware of it. A forth step of power cycling the Asus units is required to finish a hard reset - 30/30/30 and have it boot normally....redhawk

[edit] Erasing NVRAM:
As an alternative method, it is possible to restore DD-WRT to default settings without using the reset button (useful if you're locked out of the web interface or the reset button is disabled, broken, etc. or if your router just refuses to reset using 30/30/30).

[CAUTION] - On some devices, resetting NVRAM in this fashion may cause more problems than it solves. For example, Asus WL-500g and the Motorola WR850G bootloader will not recreate default values and will not boot properly after being reset. If you do this on a Siemens SE505 V1, your router will not be accessible to you anymore! You will have to reflash it with the stock firmware on IP address 192.168.1.1 (NOT 192.168.2.1 as the installation procedure says!!)

The following requires that DD-WRT already be installed on your router, and Telnet (or SSH) services be enabled and accessible.

Telnet (or SSH) into 192.168.1.1

Issue commands:

erase nvram
reboot
or

mtd -r erase nvram
All should be in default settings now.
