I recently jailbroke my iPhone 3gs with jailbreakme.

At the beginning everything was working well. But since yesterday I am having problems with the network. It would disconnect from wifi and there is no way that I can reconnect until I reboot my phone. It happened twice so far, but I am not able to reproduce the problem as it doesn't happen all the time.

Anyone here has any hint on what I should check?

Edit: I found out that this problem occurs if it changes wifi network.

Edit: Resetting the network settings was the right solution for me. Does anyone know if this is a common problem? ( I was not able to find anything with google )

That happened to me too, and now my wifi doesn't work anymore so you should expect that. (not much an answer just a comment)

3 possible fixes you can try: (they did not work for me)

1) Reset network settings: Settings -> General -> Reset -> Reset Network Settings.
3) When connected to your network click more info (the little > icon) and check if DHCP is enabled.
2) The last thing Restore your device from Itunes or reset the device from Settings -> General -> Reset -> Reset All Settings.

Thanks for your reply. I started to notice that it happened to me when I change wifi network. Is it the case also for you? – Mr Woody Aug 16 '10 at 10:00

something strange happened on this website: I was only able to see only half the comment and this is the reason why I replied that way. Solution 1) worked so far. Hopefully the problem will not appear again. – Mr Woody Aug 16 '10 at 13:38
yes this is a really common problem too bad it wont work for me too :( – Vlad Patrascu Aug 16 '10 at 17:38

Have you tried resetting your network settings?

Here's how to do it:

Settings >> General >> Reset >> Reset Network Settings.

That usually solves network problems. If it doesn't work for you, please post back here and I'll try to help some more.

yes, thanks... this solution worked for me Do you know what exactly happen during network reset? – Mr Woody Aug 16 '10 at 13:39
Cool. Glad it worked. It resets all network connections (WiFi, 3G/ EDGE, Bluetooth). Clears stored networks, passwords, etc, so when the phone reboots, all communications have to be renegotiated. I tried to find a decent article on, but this was all I could find: "When you reset network settings, your list of previously used networks and VPN settings not installed by a configuration profile are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and “Ask to Join Networks” settings are left turned on." – Thomas Aug 16 '10 at 14:23
Thanks again. I wonder why this tricks solves the problem that I had, since I tried to reboot but it was not enough. Probably it is related with the permission of some special files. – Mr Woody Aug 16 '10 at 14:30
