Hi I've experienced such situation that when I enter the QoS (view graphs or view details) the router gets no response, the connection is being cut. The router reboots somehow. It looks like the cpu has overflow? It's hard to say what could be wrong. It happens when uptime is a few days. It isn't happening always but once for many "clicking". I've found that in versions >1.07 i think. I've used original tomato and speedmod and sometimes it's happening. Sorry for my poor english. Everything what I could I made; reset everything, setting everything from start etc. I can add that it isn't only my experience - some people from openlinksys.info have got the same problem. Maybe someone know what it could be?
