Please make sure you tell him that you have tested and observed a performance issue with your Broadcom BCM43224. I know you had noted that in one of your posts. So it's not only a link speed issue, but also a throughput issue. I guess what I'm trying to say is....it's just not an erroneous link speed. Performance is involved too.
My Broadcom BCM43236 suffers the same 54-108 Mbps link speed issue.
It seems like a couple other people with centrino were still having issues as well.
Yep, I'll bet that they'd be glad to get some Broadcom chipset testers as well.
