I see that tim felt that we should,

go to NetGear's support website & download their latest code for your particular router

I did that and found that I already had the latest firmware (V2.0.25_1.0.1NA) installed on my Netgear WGT624v3 router since about 5/1/2008.  ... but that still failed to allow an accurate ZIP download. 

It follows that Netgear may not be aware of this issue for my specific model and firmware change level. 

I'll need to have additional information to get Netgear to work on a fix. 

Please provide me with additional details about the recent changes that were made in your configuration and led to this problem ... information from your new ISP and/or co-lo techs may also be needed. 

Thanks.
