Windows laptop works with Wi-Fi AP, phone claims it is connected but can't access Internet There's an Asus 240 MIMO Wifi access point. There's a laptop running Windows XP that uses that access point no problem for years so far. And there's an Android based HTC Desire S smartphone that has problems. The objective is to make the smartphone access the Internet via the Wifi access point.

I open "wireless networks" configuration pane, "enable" Wifi - it goes through "scanning" and "obtaining IP address" stages, says "connected to TheRightNetworkName". The Wifi symbol is displayed in the bar under the top of the screen. Yet when I try to open any page in a browser if wouldn't do so and claim there were problems accessing that page.

I tried the following (listed in this answer below, thanks to user Matthew Read):


rebooted the phone - doesn't help
checked MAC filtering on the AP - it is disabled
disabled the firewall on the AP - doesn't help
tried to change channels - doesn't help, the AP has 13 channels if that matters
tried to change to 2.4 GHz - looks like it is already the only option, couldn't find any way to change the range
didn't try to switch from WPA that is currently used to WEP because it feels quite scary - I can mess things up
tried switching modes - b, g, b/g - doesn't help


How do I debug and resolve this issue?
Make sure that you are using DHCP on your phone; if you have a static DNS set and it's the wrong one, you won't be able to browse the web.  Go to Settings-&gt;Wireless And Network-&gt;Wi-Fi settings, hit the context button (or right click button, or whatever you call it), select Advanced, and make sure Use Static IP is unchecked.
