If you wouldn't mind test your UI reboot theory (FYI not new) with the 5Ghz set to "N Only" and 5Ghz Channel Width set to "Auto". Expect one last random\delayed reboot. After that last reboot see if accessing the UI causes another one. This should be easy since you had 4 reboots in a short time.

This would be very helpful.

Thanks for the reply. I changed my 5GHz to N-Only, security is WPA2 Personal, Channel Width and Channel are set to Auto, and Broadcast SSID is disabled. That didn't solve the particular disconnect/reboot issue I'm experiencing.(Are these settings still in place?)

 

The router didn't reboot itself initially after changing the wireless settings (I mentioned the reboot would be random\delayed), so I initiated the reboot through the admin interface Diagnostics tab of the Troubleshooting page(Doesn't count as last reboot I mentioned). Then I poked around randomly through various tabs of various pages/widgets in the admin interface. After about 7 minutes it rebooted itself (This is the reboot I mention). I was in the Status tab of the Troubleshooting page and I had clicked on the DHCP Client Table button. The table opened but had an unexpectedly blank table (no devices listed). Clicking the Refresh button on the table is where it got hung with the Waiting animation from the admin interface and then the Windows network icon in the system tray changed to indicate there was a network connection problem. I presume something had crashed on the router right before I clicked the DHCP Client Table button and then it rebooted. After it rebooted I continued to poke around the admin interface some more to see if I could get another reboot. And it rebooted again about 20 minutes (You didn't make any changes over the 20min? Some configuration changes trigger a reboot by design like other router model) later while in the Network Map page. Since my last message post I didn't have the admin interface open in any browser tabs and I had an UpTime of over 3 hours, until I started poking around the admin interface again and then it rebooted twice in just under a half an hour. (Did your Uptime reset for these?)

 

Some more food for thought... When I login to the admin interface, there are several widget boxes on the right-hand side of the page: Network Status, Linksys Home Networking, Network Map, Parental Controls, Media Prioritization, External Storage, and Guest Access. Based on how the page appears to work, these widgets are active at all times whenever the admin interface is called up in a browser. Even if you open a specific page/widget, it appears that these other widgets are probably still running in the background. Since I'm getting reboots at seemingly random places and even if when it's just left idle in a browser tab, that might indicate one of these widgets (like the Network Map) that regularly refreshes itself might be causing something in the router to crash which causes it to reboot. As another test, I'll disable all of the extra widgets from displaying on the main admin page and see if that helps and then re-enable them one a time until I notice the rebooting again.
