I've been troubleshooting this over the past few months but have had no luck so far other than narrowing the cause down to my TiVo Minis. Intermittently my LAN will become unusable. Internet connectivity stops and access to devices on the LAN stops as well. Through trial and error I've found the issue is caused by my TiVo Minis. If I unplug devices one at a time from my network switch until things become usable again, it's always a TiVo Mini that is the culprit. Originally I thought it was just a freak occurrence, then perhaps one of my Minis was just having a hardware issue, but since then I've found that it happens with multiple Minis - it's not always the same one causing the trouble. Pulling the network cable from the Mini brings everything back to normal. Power cycling the mini also brings things back to normal. Until the next time. This only started happening I'd say around 6 months ago. Most of my Minis are older (pre-Bolt), but I have 1 or maybe 2 that are newer. So far it's been the older Minis, never a newer one causing the issue. My switch is an older Netgear 48-port gigabit that I've had forever. I'm not sure what triggered this, but it has become quite annoying. Before I blindly try replacing this expensive switch, has anyone else experienced anything similar and/or have a fix? Thanks!
