Anyone seeing issues with Dell 1490 client cards on Dell 430 or any x30 series laptop. I am in a rather dense AP deployment in a hospital. I have many of these that seem to have a problem with their speed ranging up in areas that have great signal coverage. A Cisco 21AG card seems to work great in the same laptop as well as other 1490 series cards in other Dell laptops. Dell does not seem top offer much information as per current issues with their products.
