Linksys network have to reboot the network every few days

I have a wireless network with two linksys routers.

One router is upstairs and it's connected to the modem, the network is handing out DHCP on 192.168.1.x and the second one is downstairs connected to the the first one via ethernet and it is handing out DHCP with addresses on 192.168.2.x

I am using ethernet over powerline adapters to get the ethernet signal to the downstairs router.

There are two wireless networks, with separate SSIDs "upstairs" and "downstairs."

This is working well except that every few days the network goes down and I have to reboot the modem and then the routers to get the network back up again.

Does anyone have an idea of why this might be happening other than maybe the modem connection is going down every few days? Is there anyway to find out specifically what might be causing these outages?

Check the 'client lease time' in linksys router to be set at 0

They might just be losing the ip lease at the same time

Or set the lease time on one for 2 days  '2880'

And the other for 3 days '4320'

If you are using dsl, make sure the option for 'always on' is checked.
