(Continued from a less relevant thread)
1) My location: City and State.
Folsom, CA
2) A description of the problem.
Internet drops occasionally, but with no visual indications on the modem (that is, status lights still look ok). It comes back up within a few minutes (sometimes 1-2, sometimes 4-5).
3) Is the issue intermittent, constant or does it occur at a specific time of day?
Intermittent at random times and days.
4) Your modem make, model & firmware version. How to find firmware version: Access modem
Motorola Arris SB6183, software version D30CM-OSPREY-1.5.2.3-GA-01-NOSH
5) Describe any home networking if applicable. (i.e. routers, hubs, adapters, etc.)
I don't think it's related, but just one router (plus a switch).
6) List any firewall and/or anti-virus software you have installed. Include what version you have.
Just Windows 10-installed stuff (no 3rd party AV or firewalls)
