I believe the following will correct some configuration issues on this router and should help solve this need of rebooting the router everyday:
Setup/
Wireless:
I'd set Mixed G and N mode only or if you can, go single mode N if all of your wifi devices support N mode and Change to Auto 20/40Mhz. If all of your devices support AES, I'd set WPA2 and AES only. If not, leave at Auto TPIK and AES. Theres no need to broadcast modes that are not being used.
Networking:
Change the Device name under Networking to something new. Can been anything fun. I test to use the name of the router, HW and FW version.
Input a LOCAL LAN NAME, can be anything, should be same as what your PCs can use for there work group name.
Check mark to enable Always broadcast : (compatibility for some DHCP Clients)
I recommend setting Reservations for all devices.
IPv6:
If your not using this or your ISP doesn't natively support it, set it from Auto to Local Lan Only.
Advanced/
QoS, if your gaming on PS and PC at the same time, we should set up some QoS rules at some point.
Firewall settings should be Endpoint Independent for both options.
Advanced Wireless you can test WiFi by disabling Short GI.
WPS can be disabled if your connecting devices using the SSID and PW.
Advanced Network you should enable IPv4 multicast streams and disable IPv6 streams.
Disable IPv6 firewall since it's not being used.
Also if IPv6 is not being used natively on the router and is disabled, I recommend disabling IPv6 on the PCs as well, this stop them from pinging the router unnecessarily for it.
