Wifi Connected but No Internet Access
I've been battling this problem ever since I got my AT&T Captivate. I have had trouble getting internet access over the wireless connection at my work. I have had this challenge with two different routers. One was a Linksys, and the current one is an Apple Router. I can connect to the Wifi, but I don't get internet access. I have an app on my phone called "Ping" and I can ping my Windows 7 desktop, but no Internet. When I was on Android 2.1 I could boot to recovery, clear the cache and it would work until I left the office for anything. I could have it working, leave for lunch, come back and it would not be working again. I have 2.2 on my Captivate now and it doesn't work at all. Other people in my office have no problem with connecting to the Wifi, whether it be iPhones, Blackberries, or laptops. It seems to only be affecting Android phones. Mine is not the only one with the problem.
Another piece of information that might be interesting is that on my laptop I had a dual boot of Ubuntu and Windows 7 x64. When booted into Windows, the internet worked fine, but when logged into Ubuntu, I couldn't get internet, whether it was Wifi or hard wired in. I know this forum is for Android, and that is all I'm really trying to figure out. I just figured this might mean something to the smart Linux people out there because from I understand, Android is based on the Linux kernel, and my other challenge might mean something.
Here is some info about the router right now: The Apple router is an N router with 2.4 and 5 GHz, no MAC filter, WPA/WPA2 Personal Security, using DHCP, and it is in "Bridge Mode". I'm not sure what bridge mode is all about.
I was thinking my problem might be cause by a firewall, but I'm not sure.
I use my phone on Wifi at my house and it works perfectly.
Thank you in advance!
