Arris Router and Time Capsule losing network nightly...
I could use some advice as I'm losing my mind over this.
We are Charter customers with 60 download speed and an ISP provided Arris TM902 Router. I have 2tb Time Capsule that's new.
For the last five nights, we've lost our network between 9:00 and 10:00 (ish) consistently. I've been using this user-submitted fix to reboot both systems in the right order which seems to fix the problem but the Arris is still dropping Internet each night.
** Two days ago when this happened I was trying simple reboots of both machines and discovered that if I set the TC to Bridge mode, my iMac could connect to the wireless and internet, but none of our iOS devices could log into the Wifi. Setting it on DHCP and Nat would cause the Router to jump off the network again and by resetting back to Bridge I would get the same thing over again.
Occasionally during this time I would get an amber Double Nat code but it wasn't (or didn't seem to be) consistent.
Any advicewould be very welcome. Here's the appropriate timeline if that helps:
1. Lost signal first time Wed. pm (possibly after 11:00 pm CST).
2. Thurs. morning ran power cycles on TC and Arris; wife reported that the network and wifi "just started working again" that day;
3. Thurs. night lost signal.
4. Fri. called ISP after experimenting with solutions, which is when I found most of what I describe above in the ** paragraph; they said "the phone switch" (I have no idea what this is) wasn't working and referred me to local dispatch. While I was waiting, tried the forum-response linked above, and this seemed to solve problem, BUT the TC did not appear to be factory reset. Many of you will probably appreciate that Dispatch did not call to see about scheduling a visit until AFTER I had "fixed" it myself. They did not come out.
5. Fri-Sat. night, lost signal again. Power cycled systems and it seemed to correct.
6. Sat. night Router went out exactly around 11:36 pm; Woke up this morning and still out. Tried linked solution, fixed it again.
Wondering if a new router could possibly address the issue or if this is really just something I need to fix either in network or DHCP lease? I am completely stumped.
