I have some issues with win 7 64 bit pro. I have 3 computers on a cat 5 wired home LAN using a DGL-4500 router and in yhe same homegroup. All are gigabit capable. 2 are regular PCs, one is an HTPC. All have the latest drivers.
1) File transfers never exceed 12% of the network capacity.
2) If I transfer from computer A to computer B's public folder, I can transfer 1GB in a few minutes. However, if I attempt to copy/paste a file from Computer B's public folder to computer A, computer A takes forever "discovering" the file, then gives some absurd transfer time, say 11 hours for the same file.
3) If however I go to computer B and paste the same file into Computer A's public folder, the transfer takes only a few minutes.
4) If at any point during scenario #2 I right-click B's public folder from A during a transfer, I get the spinning circle forever which 90% of the time results in Explorer hanging and requiring the process to be killed/restarted.
Any suggestions on how to go about fixing these issues?
Ok, partially solved. The speed issue is fixed, I now max out the Gigabit connection. I disabled all of the offload features in the NIC settings and ran speedguide.net's tcp optimizer. Now it transfers about a GB in around a minute.
It still locks up with a right-click on the network drive and other things though.
