It is recommended that you restore the router to factory settings to see if the MAC address of the phone is blocked. If you still can't access the Internet, it is suspected that it is a bug in the iPhone system (system vulnerability, some users report that the iOS system cannot connect to WiFi), upgrade the version can be solved, and the upgrade method is as follows:

1. OTA upgrade: Open the phone's settings - general - software update, and choose to update the system (in the case of WiFi, and keep the power at about 60%).

2. iTunes upgrade: computer** a latest version of iTunes, (preferably the latest version, otherwise it may cause unknown errors when upgrading), **Open after completion, connect the phone to the computer, iTunes will automatically pop up a prompt of whether you need to upgrade the system, click to confirm or directly click the upgrade button to upgrade.

3. It should be noted that the jailbroken phone cannot perform the above two operations to upgrade, if you want to upgrade, you need to click No in the prompt that pops up after **iTunes and connect to the computer, and then select the restore button next to the upgrade button to reinstall the system upgrade, please pay attention to the backup before upgrading, this operation will erase all the data of the phone.

Reset the network settings in Settings General Restore.

It is very difficult to crack wifi, and it is not easy for ordinary notebooks to achieve that huge calculation, not to mention your small iphone, although the technology is high, but it will not be so easy to get things right. The wifi password cracking software on the iphone is run by using a large password dictionary to guess the number of passwords, if the password that happens to be cracked is a number plus English, irregular points, the probability of being cracked is not high. Forced to let your little iphone crack his brother's head,I don't know how many times you have to try to succeed,It's normal to crash occasionally.,That software isn't very perfect.。

I'm also having this issue, the backend is all down and down"Background refresh"The only possibility is that iCloud is syncing.

Synchronize the system settings, and turn off the computer if it's still rotating for a long time.

Swap out the wifi and turn it back on.

Or turn it off and on.

I'm also this problem, just turn it off and turn it on!

It may be the reason why you upgrade the system.,It's no problem to brush the system back.,Sensei said 5 even after 5s brushing a lot of software flashback.。

Isn't this already connected? If not, the computer under 360wifi, the connection will be fine.

If you can't jailbreak because of OTA upgrade, then connect iTunes to back up the data in your phone, then click Restore iPhone, reflash it, jailbreak it immediately after activation, and then connect iTunes to restore the data backed up before after the jailbreak is successful.

Is jailbreaking important?,If it's to install free software,You can install a synchronous push.。

Then you can sail the group.
