I Can't Turn On My Wi-Fi - Dell Inspiron 1501 Notebook

On many laptops, there is an external switch to turn the wi-fi on/off. This is normally found on the front or sides of the laptop case. It can be easy to turn off the wi-fi accidentally if you grab your laptop a certain way that causes you to press the switch.

On some laptops, you will find the wi-fi on/off switch by raising the laptop screen to expose the keyboard. The switch may often be found by looking at the area above the keyboard. In almost every case, the wi-fi on/off switch will be lit if the wi-fi is on, and unlit if the wi-fi is turned off.

Solution 1.Check wireless connection.

Hello Jane,

When using a Wi-Fi network with your iPhone, you may occasionally encounter the following issues,Unable to locate or join a nearby Wi-Fi network,Weak or low Wi-Fi signal strength,Connected to Wi-Fi network, but unable to access the Internet.
Tap Settings > Wi-Fi and turn Wi-Fi off and then on again. Verify that you are in range of your Wi-Fi router or base station. Confirm that your Wi-Fi router and Cable/DSL modem are connected to power and turned on. Check whether other devices (portable computers, for example) are able to connect to the Wi-Fi network and access the Internet. Update your Wi-Fi router to the latest firmware.

Hello!
Here are the things you can try for a malfunctioing Wi-Fi on your Galaxy S:
Try turning off your Wi-Fi then turn it on again.

• Sometimes, this works for me as the Wi-Fi might need a restart so it can try scanning again. You can do so by going to Settings > Wireless and Network > Wi-Fi Settings and ticking the Wi-Fi checkbox.

Turn off your handset then turn it on again.

• An app that was running on your handset might be messing with your Wi-Fi, so to make all things better, you can restart your handset for a fresh boot. :)

Check if there are actually Wi-Fi networks in your area or the Wi-Fi is too weak.

• If there aren't any Wi-Fi networks to detect, it can't do anything at all in the first place. Try moving to an area with better Wi-Fi signal.

You can ask me if you have any queries! :) ~azukibean70

Wi-Fi settings determine whether iPhone uses local Wi-Fi networks to connect to the Internet.
Turn Wi-Fi on: Choose Wi-Fi and turn Wi-Fi on.
Join a Wi-Fi network: Choose Wi-Fi, wait a moment as iPhone detects networks in range, then select a network. If necessary, enter a password and tap Join (networks that require a password appear with a lock icon).
Once you join a Wi-Fi network manually, iPhone automatically joins it whenever the network is in range. If more than one previously used network is in range, iPhone joins the one last used. When iPhone is joined to a Wi-Fi network, the Wi-Fi icon in the status bar at the top of the screen shows signal strength. The more bars you see, the stronger the signal. Set iPhone to ask if you want to join a new network: Choose Wi-Fi and turn "Ask to Join Networks" on or off. Join a closed Wi-Fi network: To join a Wi-Fi network that isn't shown in the list of scanned networks, choose Wi-Fi > Other, then enter the network name. If the network requires a password, tap Security, tap the type of security the network uses, and enter the password. You must already know the network name, password, and security type to connect to a closed network. Some Wi-Fi networks may require you to enter or adjust additional settings, such as a client ID or static IP address. You can type it manually by login onto the Belkin's network page using the browser and by copying the static and dynamic IP address.
