I have installed http://www.myopenrouter.com/download/dd-wrt-kong-mod-netgear-wnr3500lv2-... on a new 3500Lv2. Everything seems to work just fine except the web management interface. After a little bit of use, it stops responding. Often just clicking on the tabs on top is enough. I can restart httpd via ssh and it will sometimes work and sometimes won't. Sometimes it will just give me the info page.
The only way I've found to bring it back up reliably is to reboot the router. Then it works for a little while and then acts up again.
I've tested multiple browsers and devices and it doesn't respond to any of them once it stops. Has anyone else had similar issues? I need to be able to reliably change Access Restrictions for my kids and this is causing some definite issues.
