Comment 123 for bug 291760

I just performed a clean install of Maverick and I am still experiencing this issue (I kept my old /home partition). This issue is NOT FIXED in Maverick as far as I'm concerned.

I have a Broadcom BCM4322 card in a MacBook pro 5,5 with the Broadcom STA driver. My brother's laptop is an HP tx2000 with an Broadcom BCM4328 and the Broadcom STA driver and it does the same thing on my wireless router at home. This issue appears for most of the wireless routers to which I connect (mainly home and school), and it seems to be less of a problem when I am doing a long download that keeps network usage constantly high. I think I can also sometimes avert it by running several pings to external addresses. I would be willing to do any tests/log lookups if you give me specific directions, as this is a huge online productivity killer.
