Hi, I have WDR4300 which was bricked. I followed the procedure to enter failsafe and make factory reset. Then I remembered that when I bought this router I've installed only squashfs-factory version. 2 months the router was working excellent since I bought it. Now I have upgraded the firmware to sysupgrade version. SYS_LED is not blinking - just it lights constantly. Is this normal? I have reflashed to OpenWRT from stock many routers like WDR3600, TP-Link WR841ND, I have them in one hotel adn they're working nonstop without any problem! Do you have guys problem with this router before? I think I'm going to buy Mikrotik RB951. This thing just drives me crazy how good and stable it is. And ofcourse it's with very long range! Thank you.

what file did you flash? Have you tried to telnet or SSH in?
