Internet isn't working after power outage

[Steiner_Man]

Hi Guys!
After every power outage(which are pretty frequent here) my internet wont work for a long tine or at all. If i plug the internet cable into my rounter,then a cable from router to pc,the WAN LED is lit but the WLAN LED is not. Wi-fi doesnt work either. If i try to connect the internet wire straight to the computer it doest work either,same issue. At the internet icon in the bar it shows the yellow triangle with the "!" in it. Any help?

When the power comes back on, how long can't you connect to the internet before it corrects it's self?

There may be an issue with your ISP's DHCP servers.

In previous occurences,it has veen around 6 hours,but now it is about 7 and nithing hapoened yet. I do not think it is the ISP because ny neighbor has tge same thing and when he has a power outage nothing happened to his internet or router
