No Internet After Reboot

[Xenos8]

I've notice that my XR500 can't seem to find an Internet connection when it reboots.  Whether I perform the reboot (and reboot of modem) or after a power failure.  I learned a little trick that if I unplug the WAN cable from the router and plug it back in it seems to find the Internet.  But why do I have to do this extra step.  Just wondering if anyone has experienced this issue.  I am running the most current firmware btw.

Sometimes it can be finicky to establish the connection, if you set static details then it should be much quicker.

Can you explain static details?  I receive my IP from my ISP via DHCP.

Take a look at the automatic details, do they change every time you reboot? If not, you could just copy those details in and make them static.
