My router is a Netgear WNR3500L/U/v2 running Tomato Firmware v1.28.9054 MIPSR2-beta K26 USB Ex. The share drive always shows and I can access it. I am able to copy from the share drive to a drive on the pc, I can cut/paste also. Then it quits. I can still access the drive but the delete, copy and paste quit stating that there is a problem accessing \\TOMATO\Files make sure you are connected to the network and try again. It may start working again on it's own. I can't figure out why it's doing this.
