I'm experiencing intermittent connection errors in our home network from two different computers, normally "Connection Reset" when browsing, but also other issues such as very slow throughput. I have approximately a network setup as below:
ISP->Cable Modem->Dlink DIR 655 Router->(Ethernet)->Fon Router->Mac/Windows laptop
Basically, is there a simple way to monitor the network and detect where issues are coming from? Right now we don't know if it is the Fon router, the Dlink router, the modem or the ISP. As the issue is intermittent, is there a software that regularly traceroutes a set of destinations and tests e.g. throughput, something that can help us figure out where in the chain the errors are introduced? The more automatic network monitor, the better.
