wireless troubleshooting

My laptop has a wireless signal but I cannot access any website. I can ping 4.2.2.2 but the ping time is around 150ms. When I plugged my laptop straight into Verizon router, I cannot access the Internet without any problem. How do I troubleshoot my wireless? I already reset my router several times. Thanks

One place you can start is to install Wifi Analyzer on your phone to check for interference on the channel

Here are some other thoughts

What type of Wifi are you using 802.11 a/b/g/n If you are connecting with "a" then it will be slow

How strong does Windows report the signal strength?

You wifi router could be malfunctioning. How old is it? Has the firmware been upgraded?

Are you using the most recent driver for your network card. Ensure that this driver is up to date

I have a very good signal. I have 4 laptops and this one is the only one that cannot access the Internet via wireless.

Yes DNS is the issue. It is set to 4.2.2.2. When I removed it to set it whatever the router gave it. It works fine. I don't understand why 4.2.2.2 did not work. It is a valid DNS server. Thanks

firewall blocking or ISP? Can you ping or nslookup and use 4.2.2.2 as the server. ie nslookup then server 4.2.2.2

How about while on wifi or was that on Wifi?

Could the wifi router not be forwarding DNS requests for wifi clients? How makes the AP
