The Jelly Bean official update makes the HTC EVO 4G LTE users pleased, but unfortunately there are some users who reported that they had WiFi problems after applying JB firmware (3.15.651.16) via OTA. The symptoms are actually various between devices, some of which can’t detect or get connected to the wireless router, randomly switch off especially when the screen is off, Wi-Fi signal dropped, and can’t access the internet even though it’s connected to the network.
The WiFi feature is very important for HTC EVO 4G LTE users since it could save the 3G/4G data usage, some users even rely on WiFi when they need a fast connection as their area is not a part of Sprint’s 4G coverage and 3G speed is still slow.
There are several ways you can do to fix the WiFi problem on HTC EVO 4G LTE, please note result may vary, it can be successful but some are not, so the following might not be able to resolve WiFi problems on your device:
- The first solution is switching off “DLNA Auto-IP”, on Settings > WiFi, menu and select Advanced.
- Try to change “Wi-Fi frequency bands” in the Advanced Menu to “2.4 GHz only”.
- When most of the fix can’t solve your problem, factory reset is the next thing. Remember after performing a Factory reset and return to the default settings, don’t restore the data from your Google account, because chances are the data isn’t compatible with the Jelly Bean OTA that might sooner or later broken your Wi-Fi again.
- The last step if you can’t manage the WiFi problem on HTC EVO 4G LTE is to install a custom Android 4.1 ROM (which has Wi-Fi bug fix). To begin this, your phone need to be unlocked bootloader, has custom recovery (TWRP) and rooted.
