Can connect to Wi-Fi, but internet wont work on WPA2-PSK

[PskAuto]

Heres the issue: when I set my DLink router with a WPA2-PSK or WPA password, the internet won't work, but the wi-fi does connect. If I set it to WEP, I am able to connect to both the internet and wi-fi, but only on Windows 7.

Can anyone explain?

With any modern equipment you should be able to use WPA2 (PSK) AES, the personal not enterprise version, on your home network. You don't want to use TKIP. Using AES and turning off WPS makes your router more secure and allows for the fastest speeds, as anything other than WPA2 AES will be speed limited.

What model router and adapter?

I assume that your cell phones will connect on WPA2?

HERE is a brief description of the various wireless encryption types available.

Is the router new? If so, what is this router replacing? Or did you previously connect and work through this router? If so what changed? Or are you saying you've used this router with no encryption and now you are having trouble adding encryption.

Is the cable or DSL modem combined with the router, or are they separate ? If combined did you successfully log into the ISP's fabric (PPoE, etc.) from the DLINK router? If separate, does the ISP's modem do any router function like NAT translation? That can mess up DNS when you cascade it through a second router, especially if IP ranges overlap. If you have two separate boxes and NAT is not a term you understand then post model numbers.

By "internet won't work" do you mean that the modem says there is no internet, or do you mean your PC cannot access sites on the internet. If the latter then there is lots of debugging you can do. First step is to run the windows built-in networking troubleshooter. Another step would be to go to a site by its hard IP address (e.g. ping www.amazon.com from a cmd prompt and see its IP address is 54.239.25.192. then enter that in the browser, you will get a warning, then in advanced you can tell it to go anyway, in which case you get to amazon. do NOT use any hard IP address you find in the forum, use one you know is the correct IP because you had a working connection ping it).

Giving the pcs and phones in your network might help. Which one connect which don't. Assume that with no encryption that all your devices can get on the internet without difficulty through the DLINK ?
