Not able to connect to internet

I said that because I tough you don't get a enough signal to config the network, but if you get good signal is good, you save the step of coming closer to the modem

Also if I have the tablet or the labtop in my room and they get a good signal and the xbox shows that the connection is good. then what could be the problem?

A sequential power cycle is the first step in clearing connection problems, and the order and timing of the steps is important to success:

1) turn off the Xbox and unplug the power supply cord from the back of the Xbox then

2) unplug power from the router (Some folks have a combination modem-router AKA 'gateway' or only use a modem with no router. If either, skip steps 3 & 6).

3) unplug power from the modem.

4) Wait at least 5 minutes then replug the modem/gateway power.

5) Wait 'til the light on the front of the modem/gateway which says BROADBAND, ONLINE, READY, CABLE or DSL is on solid (not flashing), then plug in the router. If you have a gateway instead of a modem and router or a modem with
no router, then when that light says it's ready, skip to step 7.

6) Wait until the WiFi light on the router is on; you may not use WiFi, but it's still a good indicator your router is finished booting up.

7) Plug in and turn on the Xbox.

If the problem persists, please send us the info we need as requested above.

maybe the game has servers problems

I cannot login to the Solitaire World Events frequently. It always starts at 7:00am CST and often shows "Internet Connection Required" but obviously I am connected. I have tried resetting the app in the advnaced settings. My gamertag is logged in but the
"Word Events" wont load.
