Trouble connecting to a trusted wifi

[lupeders]

I have an Samsung Ativ S with os 8.0.10211.204

When I have a trusted WIFI with WPA2(AES) security. The Wifi is trusted and works fine, but if I leave the wifi zone and comes back after 30 minutes it would not connect to the WIFI again. If I manually tries to connect, is Says "The phone cannot access the WI-FI network XXXXXX"

I have tried
- Turn Wifi off-on
- Erased and tried to add the WIfi again. It answers the same and cannot access.
- Reboot of the phone is the only thing that helps. Then I can add and connect to the WIFI again.

I have been waiting for updates, but I am starting to become unpatient.

Do anyone have any ideas what to do?

I think you have to reconfigure the router first.

I'm having the same problem recently on my Lumia running GDR3. I've tested multiple connections with the same results.

Testet with several trusted wifi networks. Then I would have to reconfigure all the routers.

In other words. It is not the routers.

It's not the routers. I've had the same problem since the GDR2 update. Bad news that the problem still exists in GDR3! I've found that turning wifi off then on seems to enable my L920 to autoconnect. But I have to do this each time on each network, which is a royal pain...

I am still waiting for GDR2 so It can not be that updates fault. I was hoping it would be better with an update, but I am still waiting for an update.

Restore to factory settings does not work either. Did that yesterday and WIFI still just work after reboot.

Samsung came with an network update and then everything is ok.

Hello
I have a Lumia 820 and I have had this problem with both GDR1 and GDR2 on several different routers.
I have a workaround solution. I know it sounds stupid and not at all logical, but it works everytime for me:
When ever I can't connect to my WiFi, and turn off bluetooth and then try to connect to the WiFi again.

I have know idea why this works for me, but it does.
