Just updated to the new FW 3.1.3 and now my iPhone 3G wont connect to my wi-fi. It see's it but when I select it, after a few seconds I get a error: "Unable to join the network."
I reset my router and still nothing. MBP and PS3 can get on just fine.
Anybody else having issues?

    No such problem here.

    Try selecting the network to view the network settings and then select Forget Network to remove the network and network settings from your iPhone. Follow this by re-joining the network.

    If no change, go to Settings > General > Reset and select Reset Network Settings. This will delete all wi-fi network settings from your iPhone. Try re-joining your wireless network.

    Did all of that. Still doesn't work.

    You're welcome.

    If you did all that before posting here, you should have included all that with your post so I didn't waste my time as well as yours providing steps you have already tried.

    Have you tried anything else? If so, what?
  • Goaliegeek Level 1 (10 points)
    I tried all of the things you recommended in your post AFTER you said them.
    I've restarted a few times, now I'm in the process of a restore. Don't know what else to do. Can't try another network since there aren't any others I can use around here.

    Restore didn't fix anything

    Try going back to 3.1.2

    Reading this and the other posts on Wifi problems is disturbing. My iPhone 3G is on firmware 3.1.2 so not sure that reverting back to 3.1.2 will help as I have the same problems. It also appears that 3.1.3. will exacerbate the problem. Sounds like its time to harass Apples Support staff and developers to get a proper resolution to this issue as this problem is starting to really irritate.

    I use a Netgear WNDR3700 wifi router at home. It has support for all bands. At work I use a Belkin router (exact model not remembered) I see the same problems. At my mates house with another Netgear router (DG834G) I see the same problem.

    Until the last few weeks I can't say I've had any problems with WiFi on my 12 month old iPhone 3G (firmware 3.1.2 (7D11). However, these last few weeks this phone just can't stay connected to WiFi networks for any great period of time; sometimes minutes, sometimes seconds.

    I've tried manually adding wifi networks following hints from other users on the forums, but this doesn't work reliably.

    I've now done a full reset of the network element based on advice in Apple's own iPhone WiFi troubleshooter. I'll see how that goes.

    I don't believe this issue will be resolved without Apple's action, so come on Apple please help us. We love our iPhones, just don't like to see issues with them!

    I have the same problem. My iPod Touch connects to the WiFi-network but the connection is unstable and slow. My MacBook Pro runs on the same network and has no problems. This problem have been around since iPhone OS 3.x. Apparently it has something to do with the WiFi-router since it is not a problem on all WiFi-networks. The problem is just that most WiFi-routers doesn't allow much configuration of the WiFi-signal.

    I hoped that Apple had fixed this problem in the 3.1.3 version. But they didn't. And it shouldn't even be hard since the WiFi-part of the 2.x version worked.

    I've had no problem with my iPhone 3G for last year and a half, until "upgrading" to 3.1.3 yesterday. Now no wifi and the battery is going down at a faster rate. I don't even have the option to turn wifi off or on, it is all grayed out and unresponsive.
    Is a restore the only way to go back to 3.1.2?
  • paulcb Level 6 (19,110 points)
    I suggest restoring from your backup. If that doesn't work, restore as a new phone and reset everything back up. I did this (restore as new) with the 3.0 update and it only took just over an hour. Phone ran perfectly after that.

    Does anyone know when the 3.1.4 update will be out to fix the 3.1.3?? My phone has been "hosed"...........very unhappy.........
  • CasperNZ Level 1 (0 points)
    I was having the same issue, my router was visible in the list and looked like it was connected, but 3G was still showing on the home screen. Changed from DHCP to Static and set my IP manually and it worked. And has been connected for the last hour with no drop outs. No idea why that's any different but if it helps someone then great

    Since I have upgraded my 3G 8GB iphone, it is not able to find any wifi network and the thinking circle doesn't disappear.

    Any help to go back to 3.1.2?

  • paulcb Level 6 (19,110 points)
    Nobody knew about 3.1.3 until it was out. It will likely be the same with the next update.
