  2. DNS problems with router

    A couple suggestions I have for you:

    Update the firmware on the router. Maybe it's getting into a badstate, and a firmware update might fix it. Or if you're comfortable with it, install a custom firmware like dd-wrt. Just make sure its supported on your router first.

    Change your DNS to: 8.8.8.8, 4.2.2.1. Might help.

    If none of these work, maybe statically set your DNS on your PS3/PC to the IPs you listed, taking the router out of the lookup procedure.

    Last option, is look for a new router.

  3. Forum users with Hotmail/Outlook/Exchange account

    The two-step verification emails show up in my inbox but I added a rule to mark the domain name safe a long time ago (verified that "techpowerup.com" is still in the safe sender list).

    dns probe finished no internet


    Hi Oxide,

    After some trial-and-error testing of all suggested fixes, which I found over the internet, here’re what worked for me to solve "DNS Probe Finished No Internet" issue and might work for you as well.

    Method 1: Change Default DNS Address to Open DNS


    Here all you have to do is change your default automatically obtained DNS server addresses to open DNS or Google DNS. To do this, follow below mentioned steps:

    Step 1:
    Right click on Network icon located in Windows Task Bar Menu.

    Step 2:
    Click on ‘Open Network and Sharing Center.’

    Step 3:
    Click on Local Area Connection with whom who are presently connected and click onProperties.

    Step 4:
    Select ‘Internet Protocol Version 4 (TCP/IPv4)’ and click on Properties.

    Step 5:
    Now in newly opened windows, select the radio button that reads ‘Use the following DNS server address:’

    Step 6:
    Now in the ‘Preferred DNS Server’ box type in 208.67.222.222 and in ‘Alternate DNS Server’ type in 208.67.220.220.

    Step 7:
    Now check the box that says ‘Validate settings upon exit’ and then click on OK. That’s it.
