    My samsung captivate which I just bought works on wifi for a while except when it goes into sleep mode (which turns off the wifi) and I go to use it again, it doesn't work. BUT the wifi signal is still at full strength! so it doesn't loose the connection or anything, it just stops working UNTIL i reset my phone, then it works again! this makes NO sense! can anyone help me?

    I set my wifi to never sleep so it doesn't startup a 3g connection when it wants to do something.
    Just curious, when you wake it up and pull down the status bar does it show wifi as on?

    How do you know that the phone-wifi isn't working?

    Also, do you have access to another wifi source (router)- either your neighbour's, or maybe at Starbucks? Might want to check to make sure that it's not your router causing the problems too.

    Just a thought,

    No, wifi is on, and its connected to my internet, but for like 90% it doesnt work...and the other 10% it does

    -my router is good, because my moms blackberry uses it, aswell as my laptops...

    -the captivates wifi works on other peoples wifi....i factory reset it, and it just started doing it, but before the reset it worked fine

    Just curious to know how you think it's not working....?

    As in it literally turns itself off (having to literally turn it on)?

    Cause when I'm at the house (w/ WiFi on) I will still occasionally see the 3G symbol still appear in the status bar. Thats not to say the WiFi isn't still working, but the 3G will appear with WiFi on.

    If your home router is password protected, the factory reset will have erased any wifi password / connections options that you set up.

    Your phone may be occasionally latching onto a weak open WAP, which might explain your partial connectivity issues.

    Have you checked your phone's wireless settings?

    I typed in one character wrong for the password once and it would connect fine and then go off randomly - I could access a webpage or two and then it would quit.

    Also, I have ran across 2 different wireless routers that have problems overheating and shutting down the entire network. Both of them were Wireless-N routers - one that I installed here at work and another that I installed for a business that I work with on the side. The internet would work fine and then everything would shut down. I would have to re-boot everything to make it work again. Took weeks to figure out that the one wireless router was causing the problem.

    Try going into wireless settings, deleting all the routers you have set up, and re set up your home router?

    If it works with other routers just not with your router then the odds are the problem is in your router, not your phone. Sometimes the problem is from WAP/WEP setup and the first step in troubleshooting can be to turn off all encryption (and leave the computers shut so they aren't hacked whiel you run that way) and see if everything works "plain vanilla". If it does, then re-enable the encryption and start looking at the setup options it is using. Sometimes a phone (or computer) just doesn't log back in properly and resetting the encryption options will get it working again.

    I think Rred is on to something. I'll be you're not getting an ip addy even though you're connected.
    You don't mention your isp but if it's att & you've got a 2wire router try disabling wi-fi protected setup.
    Of course you'll want to keep encryption. just ditch the WPS.
    I had a helluva time with all my wireless devices until I figured out the WPS was the problem.
    I wasn't using it but it was interfering with the connection/auth process. All the devices would 'connect' but they couldn't get an ip address. Dead in the water.

    Of course if you don't have a 2wire, forget what I just said. heh

    Are you getting a (valid for your network) ip addy?
    Ping the gateway?

    Does this happen after having the phone connected to your computer via USB? I (and several others that I have read) have a similar problem to yours but only happens after USB is disconnected. Shows connected to WIFI, good signal but no internet until restarted.

    No solution found yet.

    YES I DO HAVE 2WIRE!!!! can you please give me a step by step process on how to fix this

    i feel like you know exactly how to

    jeg, did you try running without encryption to see if that (encryption) is causing the problem?

    And of course, keep the computers shut down while you are running that way.

    You need to troubleshoot one process at a time, i.e. encryption, routing, firewall...There's no magic here, just relentless application of logic and the process of elimination.

    If you are trying to do what @Ross said above it's done through your AT&T Uverse Gateway. You access the gateway through this URL:
    http://gateway.2wire.net/ Then you need to get the system password off the side of the unit. ONLY go into WIRELESS then in the first section named Wireless interface change the drop down for Wi-Fi Protected Setup to DISABLED. Then go to the bottom of the page and click save.

    NOTE: This is just advice given I am not an expert! If you screw up your gateway I take no responsibility. If you know someone that has more experience then you may want to have them do it. I have done this and it works.

    What are the wireless security settings (on the 2wire gateway) now?
    Make a note or screenshot of them.
    Check them here: http://gateway.2wire.net/xslt?PAGE=C_2_1

    The default is WPA-PSK (TKIP) so set it to that.
    Make sure wifi protected setup is disabled.
    Save your changes.

    On your phone, delete (forget or whatever) your current entry for your network. Then touch it to connect.
    In the connect box you should see the signal strength and security.
    Since we just set the router to WPA-PSK (TKIP) you should see that as the security type.

    In the box titled Wireless password, type in the wireless network key from the label on the side of your 2wire box.
    Make sure you use the wireless network key and NOT the system password, also on the same label.

    Let us know how it goes.

    Well...now my wifi on my phone doesnt even scan networks anymore =( once i turn of wifi, it scans and then turns off, even though there are networks in the area

    im praying that samsung gets things together very soon, or i may have to look for another phone

    Even though this phone has some issues I think the wifi is pretty good.
    Do you have a lot of data on the phone? I'm guessing not, since you've been having so much trouble with it.
    Have you tried a factory reset? It will delete everything on the phone but it will restore all the defaults. It may be something to keep in mind.

    I'm tempted to say it's a hardware problem but you said it does connect to other AP's, right? If so, hardware is ok.

    Did you ever get it connected to your own network?

    Today mine started having problems. It shows I'm connected to wifi. But will not connect to the internet either. I was able to get it to connect once by removing all data in my browser. Then after pulling the battery twice it connected. Now it won't connect again. It will over the 3g.
    I have verizon fios with an actiontec router. All computers work and noting has been changed on my phone or router.

    I'm having the same problem. It connects to my wifi without a problem, but cannot connect to the internet. The only solution so far is to turn the phone off, and on again. While annoying as heck (especially because this is my first android phone, and coming from an iPhone, which for the record never have issues like this on my wifi) it works for now. Hope this get fix soon.
