Suddenly, my router(WRT54GS V3) couldn't work. After reboot, it still couldn't work. TTL=100, not 64. I tried restoring configuration to router. But it still couldn't work. I felt very strange. Then I have no choice but to reset it to factory settings and config all the settings manually. One by one. Then router can work. But it seems that performance decreased. Because if web monitoring is enabled, no python application can be started at router startup. This performance is much worse than previous. I don't know why. I just guess is it because cfe.bin changed? But actually I never changed any file. Never flashed any file. Anyone who can tell me why? Why the backup configuration restored to router still couldn't work? Why there's conflict between web mornitoring and python application? Thanks!
