    I'm having this issue as well. What did you mean by "try to set it up from the bluetooth" menu?

    I had the same exact problem the other day, I did everything I could think of, turning the mobile radio on and off, trying a different wireless network, restarting my phone, taking the battery out, etc. When I took the battery out, And turn the phone back on, It would connect to the network but As soon as I turn off the wireless network and turned it back on I would get the unable to scan for networks, Finally I did a hard reset on the phone now everything is working fine, I am not sure what really caused it. This was the first time since I got my phone that I had any problems with it.

    There is Widgets that will tell you about your signal, whether Mobile or WiFi. Have you used one of them to see what is happening with your signal in realtime? For me I use Mobile Widget Signal Pro, but the free version works just as well. I used this info to see why my AT&T WiFi wasn't hooking up to my phone. I just watched to see how my phone was trying to connect and which networks it was choosing over the AT&T. The Widgets came in handy for that purpose. It you see your signal is erratic and your phone keeps bouncing from one signal to another, then there might be an issue with your phone's radio, but try the Widgets first and just see what your phone is doing signal wise, while your trying to connect to WiFi. I hope this helps you out.

    I was able to get it to work by going to my
    Settings Menu
    - Wireless & networks
    - Mobile networks
    - uncheck Enable always-on mobile data

    It will take a moment before you can reconect using mobile data.

    I've been having the same issue for a few months now. I have to turn off Mobile Network to get Wifi to even appear. I know when the phone was new back in June that turning on Wifi would overrule 3G until you turned it off. Now the 3G radio overrules everything, including 4G. I do have always-on mobile data unchecked too. If anyone figures this out, please post your solution.

    I encountered this problem on the Samsung Transform M920. My wifi on the device would error out or activate and attempt to pull an ip address from a connected network and then drop. I found that there was an app that I had installed that conflicted with some of the settings and resources on the device. In my case it was an app called light-flow light which is used to manage and control led notifcations. After i removed this app from my device it resumed normal operation.

    Angry Re: Unable to scan for networks (wifi problem)

    I am having the same problem with my HTC Droid Incredible! I did a factory data reset the other day because it was happening...then it was fine for a few days untill now! I try to connect to my home wifi, then it says error...sometimes it will show that it's connected but then it says scanning and then a message comes up saying "unable to scan for wifi". I am so mad at it! I cannot find out what had happened. I tried uninstalling apps to see ifI had malware, scanned my phone about 5 times, made sure I had all my settings the right way, did a data reset....nothing seems to work. It is the oddest thing that has happened to my phone! Someone please help!!!! I do't have my phone activated with mobile network 3G or anything data. I only use it for apps and social mobile.

    I have exactly the same problem, and a hard reset did NOT help.

    Result: my phone (HTC Desire Z) has no apps or data thanks to the hard reset, and the ony way to get them back is through the mobile intermet, which will cost me a fortune in data.

    A complete fail. Will never buy a HTC again.

    That's not the phones fault! You have to back up the apps.

    Try resetting your router, it may be having a ip conflict. then i would toggle Airplane mode on and off a few times

    OMG I am having the same problem. EVO3D phone will not connect to my wi-fi. I have disconnected the router and reconnected. I have removed the battery and replaced it. I have scanned all my apps and files using 'lookout' everything is fine. why won't it recognize my wi-fi?

    I was having the same issue. Go to wireless networks> mobile network options> uncheck always enable mobile network. When you go back a step to wireless networks, have both WiFi and the mobile network checked. This way,it will choose WiFi first if available now. Not just always mobile network.hope this helps and is not confusing!!

    I have a 3D EVO SPRINT and the wifi scanner is turning off and on. It is a modded phone but the modification does nothing to the WiFi scanner and every time i try to turn it on it will say unable to scan for networks . I tried everything else except for factory reset . When the phone is at 10% the WiFi will start to kick on and when i charge it the phone turns off automatically . i dont know what to do besides take it to sprint themselves
