Very weird router problem

I have 2 routers, here is a quick look at the setup:
Router #1: 3 wired PCs, 1 cable modem, and a wired connection to Router #2. Wireless capabilities disabled.
Router #2: 2 wired PCs, 1 wired virtual phone, 1 wired printer. This is the router we use for wireless. All smartphones, tablets, a couple of laptop, and a shared printer connect to this router.


Recently, like around a week, I've been experiencing a very weird problem.

The internet and overall network capabilities goes down, basically nothing works at all, you can't even get into either router's configuration page.

In order to get things to work again, all I need to do is either reset Router #2, or disconnect the wired connection to Router #2 from Router #1 and the whole network works again...

It happens like every 2-3 days now, it had been stable for years.
Can't figure it out, either there is a configuration conflict I can't see, or Router #2 is going bad (is that possible?), how can I tell?

I had a similar thing happen, but no idea really what caused it. The not being able to get into the router's configuration page jacked me up, then I figured out how to do it.

When I got locked out, I ran ipconfig on the computer I was using the access the router. The default gateway was not 192.168.x.x any longer, but some other ip. Using that ip in the browser let me get into the router and change it back to the normal ip. So no idea what's causing your problem, but next time it does it to you, try that. Have you recently added a Windows 10 computer to your network?
 
Did you manually set IP address for routers, and for DHCP server IP address ranges? Could be a conflict there and you may need to manually set so they are not the same on the routers.
 
Router 1 has virtually no configurations on it, router 2 just works as a pass through, the one assigning all the IPs is router 1.
 
Do you happen to be doing a double bridge with a FIOS router? This sounds very similar to a problem I started having about 6 months ago.
 
I've seen that sometimes where a second router doesn't like packets from the first router sometimes.

Try updating firmware on both routers and reset to factory on both. Then configure them as you need.
Turn off the firewall on the second router if you can.

Change MTU to 1426 on the first router. Set that on the second router too, but probably not as important.
