If the system response doesn’t have the website you want to go to, keep typing ipconfig /flushdns to proceed to delete the old list. The last step is to visit the website address you want to visit.

– Re-enter account information from ISP

During use, if there is a sudden power cut, your computer may not be able to access the internet. However, it is worth mentioning that Windows still says that there is a network, the internet icon in the lower right corner of the screen is still blinking. It seems that there are no problems, but you still cannot access the internet. Even if you have reset the device, reset the modem many times, it may still not be able to fix it.

To fix it, you only have one solution left to recharge your account information from your network service provider. This information includes the account name and password to connect to the internet connection. (All this information is on the service subscription contract)

If you have saved this information (it is stated in the contract), just log in to the modem’s admin page, enter the password to access this page (it can be the default or with the account you switched), then go to delete (remove) the information declared last time.
