I just bought a D-Link DIR-882 and flashed it with 40352. I configured it without plugging anything in except a cable which ran to my laptop. Everything was working fine and I had it the way I wanted it.
I disconnected my previous router (which also is flashed with 40352), turned off the cable modem for 2 minutes, turned it back on and waited until it was online, plugged my new router in and connected it to the cable modem.
When the router came up, I was able to connect to it wirelessly but there was no internet. So I try to go into the dd-wrt control panel and I cannot reach it. I cannot ping it. I cannot ping anything. I disconnect the wireless and plug an ethernet cable in. Same thing.
I disconnect the cable modem, reboot the router and I can access the network again and access the router.
I then tried a 30-30-30 reset and re-flash and re-config and I get the exact same thing.
I don't think it's a hardware issue so I posted it here (also it's a Mediatek processor so I wasn't sure what subforum to post in anyway). If this is the wrong place, I apologize.
