Introducing Cox Gigablast

Kiva, the Lenovo running Windows 7 most likely doesn't even have an AC wifi adapter.  If it has an N wifi adapter you will never get more than what you posted.  The same is true if you are using an Ethernet cable.  You would have to have a gigabit Ethernet network card in the machine to get close to 1Gbs.  Obviously your Mac does have an AC wifi and/or gigabit Ethernet network card or else you could never accomplish 918.67 Mbs.  In reality you will never actually get 1Gbs.  If on wifi, it would all depend on the wifi channel you are on, and if your neighbors use the same channel or overlapping channels. 

As an example, I just got Gigablast last Sunday.  I have a couple of laptops that have N wifi adapters.  I am getting between 250 and 300 Mbs.  That is the most I will probably ever get using the "old" N technology.  However, one of the same Asus laptop does have a Gigabit Ethernet network card.  When I plug in the Ethernet cable and open Network and Sharing Center it says I am connected at 1Gbs.  However, using Cox's own speedtest in the internet tools section of their home page, the fastest I have been able to achieve is 945 Mbs, which is actually very, very good.  Also, if you are using an Ethernet cable, I recommend using Cat 6 cable.  I was using Cat 5 cable and getting speeds about what you were getting while plugged in, and switched to Cat 6 and upped it to around 935 to 945 Mbs consistently. Also, I recommend the same for the Ethernet patch cable between the Cox ONT and the router.  For some reason my installer used Cat 5, which I changed to Cat 6.  I realize Cat 5e is rated for 1000Mbs (or 1 Gbs) but I just don't get why Cox would take all this time and effort to get a fiber into your house, then use older Cat 5 patch cable for the most important link between the ONT and your router.  And yes, I am using the Netgear router Cox provided.  It s working well for me with a strong signal throughout my home. 

Yes, I understand it is called Gigablast, but you can check many other sites such as DSL reports and they will tell you that with equipment limitations you will in theory never get to actual 1Gbs.
