Unfortunately no one can be told what fun_plug is - you have to see it for yourself.

My DNS-323 is connected to Linksys WRT54G wireless router and my PC is able to access DNS-323 wirelessly (PC is using Linksys WUSB54G adapter).
My wireless connection kept disconnecting during file copy from PC to DNS-323. File size can be between 50MB to 300MB. I've alerady tried the following, but it does not help.
1. Upgraded the firmware on both DNS-323 (1.05) and Wireless Router (3.03.6)
2. Configure FTP to transfer the files
Can someone advise if such set up is supported? and possible ways to fix this issue.
Thanks in advance.

If you are going over wireless to me sounds like you are saturating the link.
Try over ehernet and see if you get disconnected.

What happens if the files size is less than 50MB? Does it transfer without a disconnection?
The symptoms you describe point to a wireless network problem rather than a DNS-323 related problem - if you have a second PC attached to the wired network, try the same file transfer to/from the wired PC from/to the wireless PC.
Networks - wired or wireless - that will permit the transfer of small files but fail when larger files are transferred usually show high levels of errors - the tcp/ip suite of protocols is designed to detect errors and will request a retransmission of the offending data packet, usually without the user even noticing - on a small file the retransmits just cause the transfer to take longer, but on large files which require the transmission of more data packets, more errors occur, resulting in more packets being transmitted, resulting in more errors, resulting in more..... and your snowball becomes an avalanche and the connection fails.

Thanks for the feedback. The funny thing is I was able to transmit a 300MB on the first attempt, but not a 100MB file on the next few attempts.
Will try over wired network instead.

Wired network worked perfectly. No disconnection encountered.
Noticed that no disconnection was encountered when transferring a large file (> 100MB) over wireless from DNS-323 to PC. This makes me think that DNS-323 does not have any buffer/cache to handle input data. Is this right?
Also, I cannot delete the "uncompleted" file from DNS-323 once disconnection occur. Error message was similar to "file is in use by another program ..." The workaround I did was to reboot DNS-323 before deleting the file. Is there a better way of doing this?

Think about it for a second, if the DNS couldn't cache the input, you would get the failure over the higher speed wired network and not the lower speed wireless network. The issue is your wireless network.
