Slow Cable Modems - Everyone Please Read
I am a Broadcom employee. Broadcom makes cable modem chipsets. Some of these chipsets have a slight design flaw. I am not at liberty to divulge any technical details. However, I can tell you that using a cable modem containing one of these chipsets with your Mac will result in slow internet speeds. Apple is not at fault. I'm sorry to say that fixing these design flaws, which only affect Mac users is not a priority at this time.
I am a Mac user myself and am just as frustrated as you are with incompatible products. This is why I am coming forward and informing you of this problem with our products. Our chipsets are used in almost all of the most popular cable modems. I am including a partial list of the most recent and popular cable modems that use our chipsets which have this problem. I am unable to find any information about older and less popular cable modems. Please understand that I can not and will not divulge any more information. Thank you.
