Can't connect to inter net.

Go to the Settings Menu, Select the Wireless & VPN option and see if you are in Airplane mode, if you are, turn that off. Then select Wi-Fi. See if Wi-Fi is turned on. If it's not turn it on. There should be a list of available Wi-Fi routers. If one is not selected select one that is open or that you have the password to. If none are open or they are locked and you don't have a password, you'll need to get a password for one, or install your own Wi-Fi router.

Are you trying to connect to a wireless access point that's running WPA encryption and the tablet won't talk to a WPA access point?

Are you sure you have the password correct?

pay your bill

try connecting to another location like the public library. it could be that your router security setting may be set too high.

Wireless networks - 29
Installation speed and simplicity Installing a wireless LAN system can be fast and easy and eliminates the need to pull cables through walls and ceilings. Components of a wireless LAN To set up your Wireless network at home you need to have the following:

Access point (router)
Access points (routers) are two-way transceivers that broadcast data into the surrounding environment. Access points act as a mediator between wired and wireless network. Most routers have a built-in DSL modem that will allow you access to a high speed DSL internet connection. The ISP (Internet Service Provider) you have chosen normally supplies a modem/router with the subscription to their services. Read carefully the documentation supplied
with your Access point/router for detailed setup instructions

type the numbers or .com address into your browser and find the settings inside your router (box). The password will be in your router or modem settings.

Hi
I presume that the tablet detects a Wi-Fi network,since you say it won't go on to it.
A couple of points here - firstly this tablet will not go onto mobile broadband as there is no mention of a SIM card capability in the manual, which can be obtained in pdf format here:
http://www.rcatablets.com/sites/default/files/RCT6203W46%20IB_English.pdf
OK - one point down, so now we are talking about wireless access points. If the tablet doesn't detect an access point, it obviously won't connect. If it can detect an access point, then you need the access code to join that particular network. When you tap on the access point SSID (identification), it should ask for a wireless key which you must enter in order to access the Wi-Fi network and get on line.
Hope this is helpful, if so would you please register that with Fixya

Firstly Check if your WIFI router is working by accessing the WIFI connection from another computer, tablet or phone.

If it does, then use the same WiFi connection settings that it has on your ARCHOS.

You could also try connecting your ARCHOS to a friend's WiFi network and if this works, change your access point parameters to similar ones.

OTHER TROUBLESHOOTING OPTIONS:
1. Check your WiFi router/modem documentation to see if it has a pairing button that needs to be pressed. Some modems have such a button that must be pressed the very first time you try to make a WiFi connection with a new device.

2. If you have to enter a password (a security code of type WEP or WPA) be very careful that you do not confuse a 1 and I (one and letter "I"), a 0 and O (zero and letter "O"), or U and V. These are common mistakes.

3. When entering a security code for your WiFi access, check the box "Show Password" which will allow you to see exactly what you are typing in. This will avoid any mistakes.

4. Some access points use what is known as MAC filtering. That means, the WiFi access point has a list of access numbers (every hardware device has a unique MAC number) which are the only ones allowed to access to the WiFi point. The person managing the WiFi modem/router should shut off this MAC filtering system to see if this solves the problem. It is recommended to shut off MAC filtering in general as this is now known to be an outdated and ineffective system for WiFi security. If you must use it, you can find your device's specific MAC address by going to Settings >Wireless & Networks > Wi-Fi settings > Menu > Advanced. It will look something like 00:16:dc:5e:9e:39.

5. Try temporarily shutting off the encryption system of your WiFi router/modem to see if the problem has to do with the encryption system you are using. The preferred encryption system is the WPA2.

The SSID is not an indication on a label on the Wi-Fi device, it is the identifier broadcasted by the device ; to find it, two possibilities :
1) if you remember its password, access the setup of the wi-fi device (your router) ; this is done thru any computer connected to the router : simply enter the IP adress of the router (try 192.168.0.1 or find the right one using the ipconfig command) in the browser, and navigate to the wi-fi settings.
2) if you can't access the router, go to the wi-fi settings of your smartphone or tablet or netbook, and find he way to show the list of the access points available in the surrounding - yours is probably the first one (the stronger signal) in the list.
Good luck.

Does the WiFi router have SSID? Did it ever connect to other WiFi Access Point before? If not some say to set the Tab on Static IP and configure the router to allow the Tab's MAC address. Hope it helps.
