Could you use below patch instead, and make a new dump of the register? I'm still convinced the breakage occurs in the antenna diversity (or rather, I believe it attempts a software diversity for your card while in fact it shouldn't). > The frame dump diagnostics you asked for are attached. This is a fresh dump taken > tonight running the driver with your patch applied. Thanks, I think I miss some information in that dump, but that is okay for now.
