Thanks for your post and welcome.
Please use the search function though as your question may have been asked, and answered, before. That way you will have your answer straight away.
The Wi-Fi connection on Windows Phone devices will disconnect when the lockscreen becomes active if the device is not connected to a charger. At that time the Lumia will switch to the cellular data connection when available. In Marketplace you may find an app which will keep the Wi-Fi connection alive when not connected. Please be aware though that keeping an idle Wi-Fi connection alive will use more energy.

Same problem here, but it seems solved.
The lumia 610 not reconnected to wifi after a while. Only rebooting the router reconnect again.
The solution (and do not ask me why) was changing the wifi router configuration. Within wireless advanced settings: Beacon Interval: 5000. DTIM Interval: 200.
And that's it.

Tweaking the configuration of the router and the Lumia 610 have come to the conclusion that the best configuration is Beacon Interval: 5000 DTIM Interval: 1.
Maybe this will help someone with the same issue....
I've been having the same trouble for the last few weeks. My Lumia 710 would only occasionally attach to Wifi, even though all other nearby devices would have no trouble.
Last night, I plugged my phone into my PC with the data cable. As Zune was loading automatically my PC acted as though my phone was new hardware and my phone all of a sudden connected to my home Wifi and I haven't had any further trouble!!
In your phone, please, go to Menu » Settings » WiFi.
1. An icon with the signal strength appears: Do you have at least two bars?
2. Does is say ‘connected’?
3. If you tap on your network, more information is shown like your IP address. Is there a DNS address?
If you can answer yes to all of these three question, we should move over to your WiFi router.
1. In the past, if you add a new device to your network, were you forced to add a MAC address?
2. Are you using automatic channel selection including channel 12 and 13? I would go for a fixed channel between 1 and 11.
If the answer is no, I would restart the router by plugging it out of the power outlet.
Did that help?
If you are able to connect, however, you have problems after a certain amount of time:
That could be an issue with WPA-Rekeying. Set that to 0 (turn off) or a very long time frame.
That could be an issue with the DHCP Lease period. Set that to a very small time period and check wether you see this issue sooner. Then set it to a very long time period. On the long term, change your router.
That could be an issue with the various power-save modes of WiFi. In that case, I would try another WiFi access-point because many have bugs here.
Did that help? Playing around with the beacon interval might influence these three causes.
My lumia 610 drops the WiFi when the screen goes to sleep. Or at least it won't update Facebook chat etc over WiFi.
Settings » WiFi » Advanced » Keep WiFi on, when screen times out. If you do not have that option, you do not have the latest OS version. Please, try to update. Did that help?
