I had completed virus and trojan scans, downloaded the latest firmware for both the router and the Studio one and I noticed that even though I couldn't get on the internet, the guage for connectivity was excellent - finally I decided to change the Channel on the router which was on 1, to Channel 6 ... and solved the problem. There had been too much "noise" on the previous channel and 11 which is the usual channel was full from other wireless stations in the area. Prior to this I had suspected that I would need a higher channel and had to download new drivers for the dell card which only uses the lower channels. Thanks for your reply and help.
My Dell indicates an excellent wireless connectivity but the pages take years to load that is if they ever do! They sit and freeze. My problem has only existed since I purchased a Netgear VGN 1000. The previous router worked fine (Billion) but it wouldn't pick up my wireless solar inverter info, so I now have to use the Netgear. The meter at the bottom of the page indicates excellent connectivity, windows 7 (64bit) says there are no problems - but firefox etc takes years if ever to load, and downloads are impossible. My iMac is unaffected.
