Under Administration-->Bandwidth monitoring, the default setting is "temporary memory only". There are also few other settings. I am not sure how they work. Now I am using the default so when I reboot the router it lost all the records. I am not clear that how NVRAM,CIFS,JFFS,or User driectory works. Can someone teach me how to set it? I am using WRT54G v4 and I just want the router keep all the records even after the reboot. Thanks in advance.
