Wireless connection problems on Inspiron 15R N5110

Hi there. I'm having problems connecting to the Internet using the wireless adaptor - it will connect initially but the connection is very very slow and then will eventually drop out and stop working.

When I connect using an Ethernet cable, there are no problems whatsoever so I know it is not a service provider issue.

I have updated the BIOS to A11 and all drivers are up to date. The wireless adaptor is Intel Centrino Wireless-N 1030

I have copied the ipconfig data to assist... please help as I need to be able to connect to the wireless network at home and university!

Thanks in advance
