I read recently that some cable modems have an internal wireless access point. Does anyone know if the cale modems provided by attbi/comcast have such a beast? Would save me some change as I'd only have to purchase a card for my laptop.
It doesn't matter that the wireless standard is 'only' 802.11b. This standard supports up to 11 Mbits/second - Your broadband connection to the Internet is only (nominally)1.5 Mbits/sec, maybe up to 3 Mbits/sec in some places.
In other words: The bandwidth that Comcast gives you will always be the bottleneck.
well...technically...that's not correct...the upload speed is the bottleneck...downstream can be up to IIRC ~150megs down (assuming lab like conditions) with a max up of ~1meg stable before there are tons of resends due to error corrections/out of order packet reception at the far end etc...but nod..the cable modem is indeed a bottleneck for transmitting...and 11G isnt the standard..B is the standard to WiFi, G is an alternative that is expected to be supported to take over the WiFi standard...
I am a Comcast tech. We are in the process of introducing home networking which we are providing a Comcast branded Lynksis wireless modem/gateway as part of the installation. The cost start for networking install starts at 199 dollars. If you prefer to purchase your own Toshiba and now Motorola sell combo modem and gateways. The Motorola I saw at Circuit City for 279 Dollars both I believe is the B standard. Hope this helps. Comcast is introducing a lot of new features. Stay tuned
Not only is there an additional monthly fee, there is a rental fee for the hardware, and there is an additional install fee for added PC's. And what's more there is no value added for the monthly fee. Unlike the previous incarnation of "home networking", there are no additional IPs included for this monthly fee.
As for new features, I'd prefer they get all the old ones working properly first.
