This can be caused by a number of issues most have to do with the router itself and not the tablet. First, let's make sure the router DHCP Server is not frozen so take the following steps:
Step 1: If the router is separate from the Cable or DSL Modem, power down the router/wireless, next power down the cable/dsl modem. Power up the cable/dsl modem wait 60 seconds then power up the router/wireless wait 2 minutes
Step 2: Try to connect to the wireless
Step 3: If you have a modem or wireless router supplied by Comcast, Verizon, AT&T or any major carrier, contact them asking them to walk you through resetting and rebooting and updating the firmware to the router/wireless.
Step 4: After the reset and update try to connect, if it fails move on
Step 5: Log into the wireless/modem - let's change the wireless encryption. Go to the wireless settings, change the wireless settings to WPA Personal and add any pass-phrase. Try to connect using the new pass-phrase.
Step 6: If you still can not connect, as a last resort switch the wirlesss encryption to WPA for testing. Try to connect, if this works contct the vendor and have the modem replaced.
