I have problems with extremely slow and/or timeouts on my home LAN during FTP uploading (downloading is fine).
ISP:ADSL --> DSL Modem (172.16.x.x WAN, 192.168.x.x LAN) --> DI-614+ Router --> Four PCs (All NAT addressed, i.e., 192.168.x.x)
I start an FTP session to a site, it starts uploading and then slows down to the point of dropping and timing out. I have tried different FTP programs. I have also tried using DMZ and Virtual Server settings.
If I remove the DLink DI-614+ Router from the picture and connect to 2-wire modem, everything is fine.
If anyone has some suggestions I would appreciate it.
