Wifi slow issues after upgrade iPad to iOS 4.3.5

My iPad is having trouble with Wifi. The Wifi connection has become really very slow on iPad 2 after updating to iOS 4.3.5. WiFi only works if it's close to the router. The device have not jailbroken and my provider is AT&T. Can any help me on this?

You can try resetting your network settings to fix the issue. Tap Settings > General > Reset > Reset Network Settings. If still not working, delete
