LAST EDITED ON Nov-14-00 AT 11:22 AM (GMT)Take it back and get another one. I (and one of the Forum readers) have seen several Linksys, etc. boards with this problem and they were bad. I am not saying that Linksys makes bad Ethernet adpaters in general. They make a lot of these boards and a few of them, like all other computer products, will be defective or will be damaged by static electricity from improper handling, etc. I have a Linksys board in my computer and it has been working fine for a long time.
