How to Resolve Readynet Router Problem after Power Failure
Readynet Router not Working after Power Outage:
I would suggest
Unplugging your modem, your router and shutting down all devices.
Power up the modem, give it a few minutes.
Plug in the router, give it a minute, then power up your PC.
If it still doesn't work, log in to the router and find the tab that has the routers IP information.
See that your router is getting an IP from your ISP.
It could be that your ISP lost power as well and their servers are still down (but I'm not actually sure if that happens).
You can try getting a new DNS server if you can still connect to some things (like steam friends) but URLs are failing; Google offers a public DNS you can use.
Also, reinstall router driver if reinstalling the chipset drivers and LAN drivers doesn't fix it, then there is the possibility that your motherboard took some damage during the power outage.
