WifiFixer

Many Android smartphones (like the widespread high-end models Samsung Galaxy S7 and S8) are unable to maintain a stable wifi connection in a multi-AP-same-SSID environment. They will not "roam" from one access point (AP) to another as you move through the covered area, but only connect to another AP once they have lost connection with the previous one. Even if you don't move around, your phone might stick to a weak AP, you might not receive push notifications, and your battery will drain with all the necessary retransmits. These problems have been known for years, but the manufacturers just won't fix them. (It is not Android's fault.)

WifiFixer periodically checks whether the currently used AP has become weak; if yes, it will scan for others that provide the same service (i.e. have the same SSID), and if there are better ones available it will cause the phone to switch to one of them -- seamlessly. Contrary to the normal behavior, the phone will not lose the wifi connection and establish it again after a few seconds (causing apps to see a network failure).

It is important to understand that this app will not help with all devices; on some it may even worsen the situation and lead to longer disconnects. If this is the case then please uninstall the app.

The free version of the software is fully functional, but will occasionally remind you that a license needs to be purchased for continuous use. No ads!

In case you are wondering why the app needs location access permission: Android will not let apps scan for wifi networks unless they may access your location, seemingly because Google believes that everyone -- like themselves -- regards access points as location beacons. We do not determine your location, and we do not transmit anything anywhere.

许多Android智能手机（如广泛的高端机型三星Galaxy S7和S8）无法保持在一个多AP-相同SSID的环境稳定的wifi连接。他们不会从一个接入点（AP）的另一个“漫游”，你通过覆盖区域移动，但只能连接到另一个接入点，一旦他们失去了与前一个连接。即使你不走动，你的手机可能会坚持一个弱AP，您可能无法收到推送通知，你的电池将所有必要的重传排。这些问题已经相识多年，但厂家是不会解决这些问题。 （这不是Android的错。）

WifiFixer定期检查当前使用的AP是否已经变弱;如果是，它会为其他人提供同样的服务扫描（即具有相同的SSID），如果有可用更好的会导致手机切换到其中之一 - 无缝连接。相反的是正常的行为，该手机将不会失去WiFi连接，几秒钟后再次确立它（导致应用查看网络故障）。

要明白，这个程序将无法与所有设备进行帮助是很重要的;一些它甚至可能使局势恶化，并导致更长的断开。如果是这种情况，那么请卸载该应用程序。

该软件的免费版本功能全面，但偶尔会提醒你，许可证需要购买连续使用。无广告！

如果你想知道为什么应用程序需要的位置访问权限：Android将不会让应用程式扫描WiFi网络，除非他们可以访问你的位置，似乎是因为谷歌认为，每个人 - 喜欢自己 - 关于接入点作为定位信标。我们不会确定你的位置，我们也没有在任何地方发送任何信号。
