Being a gigabit router refers to the wired ports, which is how his PS3 is hooked up.  It has nothing to do with a wireless signal.  

@ bolded

That is incorrect,  wireless N is backwards compatible with all other signals.  Any device hooked upto it will only be limited by the wireless adapter in that device, not the other devices on the same network. 

Ah, wired yes, ok.

And I haven't used n myself so perhaps you are right, (perhaps I misunderstood my tutor) but I was just taught that very thing about a month ago. Yes it's backward compatible, but if it has to communicate with a g device it has to do the same with other g devices using the same channel (I believe you can buy some that use multiple channels at once though)

 

Yes that is correct,  all N routers support MIMO (multiple in/multiple out) for this reason.

No, I don't think you are right about this

I have been looking it up again, and if you can have a dual band wireless access point... ie running in both 5GHz and 2.4GHz... then yes you can have wireless-n devices with a throughput that is unaffected by connecting wireless-g devices. However, if a wireless-g device is connected it will slow down the 2.4GHz band to wireless-g throughput (and same for wireless-a on the 5Ghz band, but I doubt any home users have wireless-a)

But the router you gave a link to doesn't have a 5GHz band according to this: http://homestore.cisco.com/en-us/products/linksys-eseries-compare_stcVVcatId552048VVviewcat.htm

Which means it only runs in 2.4GHz band, the same as g devices.... and if a g device is connected it slows everything down.

The MIMO technology is not the same thing as being able to transmit/recieve in both bands at once (Well MIMO allows it, but dual band is basically the same as having an "a" and "g" transmitter at the same time). MIMO is used within a single band for a better reliability and signal coverage: http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps6973/ps8382/prod_white_paper0900aecd806b8ce7_ns767_Networking_Solutions_White_Paper.html

 

Feel free to prove me wrong of course, I am only learning this myself recently, but I need some kind of proof, and it's hard to find (If I understand correctly the whitepapers I just linked to though, then I think I am correct)
