Hey guys, is it possible to make the phone automatically go to using the mobile network when wi-fi is on but not working for whatever reason? Makes no sense to keep disabling the wi-fi just so the 3/4G can be activated to complete a task.
The problem I have is with MMS messages. I thought the 3g/2g radio would take prescience over wifi but it dosent, it just its there sending....sending....sending....until I turn WiFi off then it send the message....
Drives me nuts!
I'm glad I'm not the only one having this issue. I could be home and I'm five feet away from the access point but when I wake the phone from sleep, it is connected to the 3g network instead of the wifi. It takes a solid 5 seconds to connect to the wifi network. Sometimes I even get on the left side of the notification bar a wifi signal with an exclamation point saying it can't connect to the network, but it connects anyway. Besides this problem, the phone has been a little quirky with some other software issues so I'm going to the sprint store to get a replacement, the phone is just a little over than a month old, it shouldn't be having issues.
I leave my wifi on at work but if I don't touch my phone for a while when I come back to my phone to find the wifi off but after a few seconds the wifi comes back on but half the time it works and the other half I have to turn the wifi off and then back on again to get it to work.
Thanks for the writeup TenshiNo, but mine was defaulted to "Never" and I suspect that most might be.@titanoman is on the right track here. The EVO 3D seems to have issues with latency getting the WiFi radio reconnected after it goes to sleep, which (I think) is the problem you guys are seeing.
By default, Android sets the WiFi to sleep whenever the screen turns off, which sounds like a good idea, but doesn't actually get you the extra battery you would think. This is because the phone *wants* an internet connection so, as soon as the WiFi cuts out, the 3G tries to come back on.
This is generally a good setting to change on any phone if you spend most of your day around WiFi access points, since the WiFi radio uses significantly less juice than the 3G radio. Here's how you do it:
- From the home screen, press the "Menu" softkey and select "Settings" from the popup menu.
- Select "Wireless & Networks" from your settings screen.
- Turn on WiFi (if it isn't already) and then click "Wi-Fi Settings".
- Now, hit the "Menu" softkey again and you'll get a popup menu with an "Advanced" button.
- After hitting "Advanced" you'll go to the screen were you can see your current WiFi IP address and connection info. At the top is an option called "Wi-Fi Sleep Policy". Click that.
- The options are as follows:
- After 15 min: WiFi shuts down after you haven't been transmitting or receiving data for 15 minutes.
- Never when plugged in: WiFi will always stay on if the phone is plugged in, otherwise the 15 minute policy applies.
- Never: Exactly how it sounds. WiFi will never sleep and will always remain connected.
- There's also an option here called "Best Wi-Fi Performance", but the phone warns that it could drain the battery faster. I honestly don't know exactly what that one does.
It's important to note, that this could have a negative impact on your battery depending on your use. I strongly recommend going to the basic WiFi settings screen and disabling the "Network notification" option, since this will cause your phone to constantly scan for an open WiFi when you're not connected. And, since we've just set your WiFi radio to never go to sleep, that could be very bad
Also, I would recommend turning off the WiFi radio when you know you're not going to be around WiFi for a while. There's a ton of widgets out there that make this super easy, even if you don't like the ones included with Sense. Personally, I use the Power Control Plus widget, cause I like being able to configure it with exactly with options I want.

Good luck, guys. I hope this helps.
Thanks for the writeup TenshiNo, but mine was defaulted to "Never" and I suspect that most might be.
I don't know that it is related to the phone sleeping.
Here is the scenario:
I will be surfing on WiFi fine for a while.
-Suddenly I will attempt to load a page that should work and it won't load. Progress bar sticks 1/4 of the way across.
-So I try to reconnecting to SSID by turning WIFI off/on. Phone says obtaining IP addres and reconnects, but page still wont load, even if I hit refresh.
-I turn off WiFi and leave it off and 3G kicks in then page loads.
Any other suggestions?
Like I wrote before, I think it might be an issue that HTC needs to address since others are having a similar problem.
