2.2.2 What Wi-Fi protocols does my phone support?
Your phone supports 802.11b/g/n.
2.2.3 Sometimes I cannot open web pages over a Wi-Fi connection.
Why?
Possible causes are as follows:

The x digital subscriber line (xDSL) connection failed. If the hotspot (such as a wireless
router) your phone connects to accesses the Internet through xDSL and the xDSL
connection fails, the Internet connection is unavailable. Check that the xDSL connection
is working properly and try again.

A domain name service (DNS) problem occurred. For example, if you cannot open web
pages but can access App Center, the DNS is not working properly. In this case, on the
screen where a static IP address can be set, modify DNS settings.

The websites that the Wi-Fi hotspot can access are restricted. In this case, your phone
cannot be used to browse web pages at those websites.
2.2.4 I have turned on Wi-Fi on my phone, but it cannot detect
signals from Wi-Fi hotspots. What can I do?
On a device other than your phone, turn on Wi-Fi. If the device also cannot detect any Wi-Fi
signals, verify that your router is functioning correctly. If the device can detect Wi-Fi signals,
do as follows:

Check that the wireless router's service set identifier (SSID) is not hidden.

Restart the Wi-Fi function on your phone.

Restart your phone.
