I have a SurfBoard cable modem attached to a Barricade router and 2 pcs connected to the 4 port switch.
My Cable ISP, NTL, only leases the Dynamic IP for 2 hours at a time, and so it is renewed constantly on the 2nd hour. I get the same IP reassigned each time though I've noticed.
If connected to someone elses server via my FTP client (WS FTP pro) and retrieving a large file (200MB +) my FTP client is disconnected if the lease time expires and renews whilst WS FTP is retrieving the file. I phoned the NTL tech support and they are telling me it is my router that is causing the problem and so won't support me :/
Can anyone tell me whether the constant renewing of the IP lease time would cause this problem with an FTP client, as I cannot believe that it is the router. Personally, I think the bloke was an idiot trying to get out of dealing with the problem but what can I do!
The router is set up for Dynamic IP address,a nd works fine for everything else.
