Since beginning of this month, I have had random disconnections that occur twice/trice (seems like every 10-14 hours? There are no exact times and not temperature related in the room [can happen when cool like70F degrees and hot like 85F degrees) a day ever. I seems to have narrowed it down to the cable modem when I did nonstop pings (one per second) a few times. Example of one that occurred recently:
...64 bytes from 192.168.100.1: icmp_seq=837 ttl=59 time=4.61 ms From 192.168.0.1 icmp_seq=838 Destination Host Unreachable From 192.168.0.1 icmp_seq=839 Destination Host Unreachable From 192.168.0.1 icmp_seq=840 Destination Host Unreachable From 192.168.0.1 icmp_seq=841 Destination Host Unreachable 64 bytes from 192.168.100.1: icmp_seq=842 ttl=59 time=5.56 ms ...
I also pinged from outside to my IP address and had a couple packet losses. I tried pinging my old Netgear RT311 router, rebooting all hardwares, changing network cables, etc. None of those fixed/decrease the problem. I also checked my Terayon TJ715x cable modem's logs after these random disconnections, and none of them show reboots from them.
Is my cable modem going bad? Speeds are fast for the normal package user. It is just annoying random disconnects right now.
Thank you in advance. :)
