I installed a DI-524 (Rev D1, firmware 4.0) behind a Motorola SB5100 cable modem. For the time being I left everything at default (DHCP WAN, DHCP LAN, wireless on, SSID broadcast, no wireless security).
Everything worked fine for about a day. Then the router locked up. There was no wireless signal, and the desktop connected via LAN 1 could not access the internet, ping the router, or open the web interface. All 4 LAN lights on the front panel were lit solid. After several power recycles and resets, I was able to access the the "crash recovery" login screen, and after two attempts at flashing the firmware I got the router working again.
I've been using Dlinks for years, and I've never seen this before. However, I thought it best to swap out this router for another, so I put a brand new DI-524 in its place (same rev and firmware). And just like the first one, this router worked fine for about one day. The owner of the router called me a little while ago and told me the exact same thing has happened again.
I'm going out tomorrow to have a look, but I wanted to ask the knowledgeable folks here what might be going on?
Please let me know what important info I've left out.
thank you,
