My modem/router is capable of 802.11n. My NAS is connected to the router through LAN.
My TV/BD player advertise 802.11n as well.
My laptop is old and is only 802.11g.

When I stream content from my NAS to my TV/BD player through wifi, do I get n or g?

By default N as each device should use the highest bandwidth they are capable of. But it all depends upon the actual configuration. What they are capable of and what they are actually configured to use can be different.

Well, it looks like both the devices (router and TV) both support 802.11n

If your router is configured to accept n clients, then they should connect using this.

Whether there is enough bandwidth to support video streaming is another thing altogether, and will depend on the capabilities of each device, and other environmental factors.

From my knowledge if there is a "G" device connected to the network then the speeds of the whole network will fall down to 54m(g) speeds, once the "g" device is disconnected it will go back up to "N" speeds.

I could be wrong but I'm sure I read that somewhere.

It's going to depend on the capabilities of the devices. The OP should be getting a connection using 802.11n, which is what they were asking, but throughput of that 802.11n connection will depend on several hardware and environmental factors.

Single or simultaneous dual band router?
802.11n set to 2.4 or 5GHz?
Channel width - 20 or 40MHz?
MIMO config (number of RF chains) of both router and client
Environment - range, interference etc.

Thanks for the reply.

I am using the cheap modem/router comes with vodafone. So everything will be basic (2.4Ghz, single channel...etc)

I already spent money on a NAS only to discover wifi is actually my bottleneck (NAS connected to modem/router through LAN has the same speed as usb drives connecting to modem/router through usb port when I access them wirelessly) (2 Mbytes/s)

I want to ensure where my bottleneck is before I spend another chuck of money.

Is there any way I can test the wifi speed between my BD/TV and my router?

That's about the max speed in real world conditions of 802.11g, or a single RF chain 20MHz 802.11n connection.

The best chunk of money you could spend would be a network cable through to your TV. Or move your modem and NAS next to the TV if that would be easier?

My simple piece of advice is to forget WiFi.

It's a complimentary solution to Ethernet. It is not a replacement. Unless you want the convenience of portability you should always stick with Ethernet - and even then you're still going to have specific applications (intensive database applications are one example) where WiFi is a dead loss no matter how good it is because it's only half duplex.

+1 for wired solution put also get a gigabit switch so the nas can bypass the cheap vodafone router.
