My Xbox disconnects from the WiFi for a couple of seconds then reconnects right away and it...

First recommended step in such cases is to restart the router - even if other devices work fine.

try disconcerting unneeded devices from wifi and disconnect then reconnect you xbox to wifi

Ok so what I have done to solve this is :

1.disconnect the power lead from the xbox and reconnect .

2. If first step doesn't work then go to setting then network and disconnect from wifi then reconnect and type in wifi password .

3. Reset my Internet box leave off for 60seconds and then plug back in.

If this helped in anyway please like.

My Xbox will disconnect from WIFI at random times every few minutes. I have tried almost everything. When I go to reconnect to my WIFI, everything will be fine for about 10-20 minutes then I will have to reconnect again. I have restarted my Xbox
and my WIFI. I have done a soft reset also, and nothing has worked. I have tried talking to people but that didn't work.

I've had this same issue. I did full factory reset and it fixed my problem. If you are far away from your wifi, that may cause an issue as well., you being upstairs and your router is downstairs.

With mine, id be playing Minecraft on a world with friends. And every so often, my xbox live would disconnect and therfore kick all from the game, disconnect me from the wifi. It may then reconnect itself.

Now, my xbox profile keeps disconnecting from xbox live with any game or just on dashboard.
