I am having problems with my home broadband, and I am at a loss to know why.

At home I use BT Broadband, at work we use someone called Entanet. Both home and work we use exactly the same router, and I have checked we use the same firmware. The only difference therefore is the ISP.

If I try to upload anything via FTP from home, the Broadband connection seems to disconnect, then reconnect a very short period after the upload starts.

I have tried the same process at work, and don't have a problem. I have even tried swapping the two routers, thus effectively eliminating a router problem.

In general use (i.e. surfing the web) the broadband connection at home is stable. Unless I try an FTP upload, the connection remains connected for days at a time if not weeks. But seemingly as soon as I put load on the line by trying an upload (sometimes only 10 or 15 meg ata time) the line disconnects. It doesn't happen if I send a large email, that just seems to go.

What could be causing this? Could it be BT that are blocking FTP uploads on my line? The uploads if it makes a difference are photographs going to a lab for printing, wrapped up in a zip file.
