[Q] Crazy issue wifi - Sprint HTC EVO 4G LTE

Ok so I got me new EVO LTE today. Nice device...but I have a problem. I was at a clients site today and used the wifi and it worked great. Got home and went to connect it to my network, it found the SSID, then authenticated, then showed connected. However, there is no network connection in the browser.
So a little background about this. My wife has the HTC one X and has had the same issue since she got it at our house. I thought it was an issue with her phone originally because all the other devices in the house work (EVO 4G, EVO View, E4GT, 2 laptops, 2 WDlive, and a smart TV)
Well now I know its not just her device. So what I have done and where it stands now. I used fing to see if I could see the rest of the network. I could see all the devices on it but could not ping anything. 100% packet loss.
I checked the router and it shows that the EVO LTE has an IP address that matches the one that is shown on the phone. I checked the server (windows SBS) and it shows that the EVO LTE has a IP Lease.
I am not able to ping the device from any system, including the server. I am not able to ping the router, server, or any device from the EVO LTE.
So I am stumped. Anyone have any suggestions on what could be causing this?
I have disabled the firewall on both the server and router and still the same result.

I haven't run into this situation on my EVO but I have on other devices in the past. Is your SSID being broadcast or is it hidden? I don't broadcast my SSID and that was what caused this issue for me. So broadcasting, then setting up the connection from scratch with the device, then setting the router back to not broadcast did the trick for me. Haven't had an issue since with any of those other devices.

Seems weird seeing as it's connected to the router. Do you have a mac filter on your router? Did you add your phones to it?
Try setting a static IP from the phone instead of using the routers DHCP. Look at my attached picture for an example:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}

yea very odd
No, I don't have a MAC filter. Actually, I do, but I don't have it enabled.
Using the Firmware: DD-WRT v24SP2-MULTI (05/27/11) st on WZR-HP-G450H.
Setup a static IP and still no dice. Same as before, able to see all the other devices on the network but not able to get out.
Its as if there is a firewall...but there isn't.
@Salvasaur - yes broadcasting the SSID. My device connects to it right away, no problem. Its really the strangest thing that it is able to connect, shows an IP, the router and the server show that the device is connected, but it is not able to get out.
More strange is that the issue happens on both the HTC One X and also the EVO LTE. But all other devices work just fine.

I'm guessing it has something to do with our custom built firmware because I have a similar issue as yours. If my screen is off (this isn't the SmartSync issue some people are talking about) I get the same exact issue as yours. I think the newer HTC phones drop the transfer rate so low when the screen is on that the router doesn't broadcast at that speed. I know this doesn't help you but it would be nice if you could test when you get this sorted out.
The build date for my firmware is 6/14/11 are there any updates for your router?
EDIT: I'm sure you tried these but just to be clear try turning both the phone and router all the way off and back on again, toggle wi fi on and off again on your phone, try turning on best wi fi performance on your phone (remember to shut if back off because it will destroy your battery) and if you can try it on another LAN (or if you have another router, try that).

firmware update
Updated my firmware and problem solved. ugh! spent hours on that...should have thought to do that in the beginning. Thanks for the input everyone!
