The Galaxy s4 Wi-Fi connectivity issue has been reported by Samsung to be limited to DLINK routers. This is not just an issue with DLINK. I am traveling extensively through Western US, Taiwan and China and the Galaxy S4 is absolutely terrible at maintaining a Wi-Fi signal. The phone connects to a network, for instance, China Mobile or Marriott or Taiwan Free Wi-Fi, then after a few seconds begins scanning again. If it is scanning, it will not be connected for data transmission, even though the phone says it is “connected”. I have confirmed the issue occurring on CISCO, ZTE, and Motorola routers, so it isn’t just DLINK. It must be a Samsung issue.
The only way to try to fix this is to turn on/off the Wi-Fi, which is a ludicrous solution. I counted 32 times I had to do this yesterday. What a waste of time, energy, and effort. Where these phones not tested?
Samsung, if you’re reading these threads, this is a serious, serious issue. I am already looking at HTC options to replace this phone because without constant and reliable Wi-Fi connectivity, the phone is useless for data. Apps don’t work correctly. Important communication tools such as WeChat don’t work effectively. Browsing doesn’t work correctly.
What is being done to fix this? For those of us who rely on a smartphone for our business, this is unconscionable that a product would be put into market with such serious defects.
