Here is my situation, we do not have our own router, we have a layer 3 switch and a fiber that connects to the city’s switch which then goes to their router out to a larger isp. Well Im beginning to notice some lag or times the internet doesnt even work for a minute or 2. But our lan is fine. Is there an opensource or free program to monitor this kinda stuff. Maybe something that will monitor the uptime or downtime and latency or throughput of our connection to the city. Let me know if you need anymore info or if Im not making any sense. Thanks.
