Netgear Wireless n 3700 dual band 2.4/5ghz
I have a 6mb Cable internet line, on a wireless N card i get 12mbps, which is 1569 kb/s or 1.5 mb/s, same on my iphone 3gs.
Wired i get 24mbps so 3mb/s.
I have a Surfboard capable of 36 mbps, the standard Docis 2.0
The surfboard extreme has docis 3.0 capable of approx. 160 mpbs.
What your hardware can do and what your internet feed is giving you are hardly ever the same.
I just had my Cable wiring re-wired to feed my Modem's cable line the best connection in the house, the rest of the cable ports are run off of splitters and lose signal strength.
Is your isp a cable company? ask a tech to come out and find which port ahs the best connection, and either move your gear, or have him re-route the power with a "in" - "out" switch to give you direct feed from the sourse to your house without losing signal besides 2db per 100ft of wire. Then he splits the rest for weaker signals. If your running a splitter in your house, use a good 3.5/3.5db split. but recommend not splitting the connection that goes to your modem.
goto speedtest.net and check your wireless connection. then run the same test directly wired to your modem, you can see the difference in speeds, and go from there. Also they have a ping test on the site, checks the packet loss, mine was 6% loss wirelessly, and 0% wired. so that maybe another thing to consider.
Now dual band routers run on 2.4ghz and 5ghz. You can turn off the 2.4ghz if you want, 5ghz would be a stronger signal, it just depends what interference there is, if you use 5ghz cordless phones, that would interfer now n then. same with 2.4ghz phones, and other routers near your house if your picking up there signal to.
Dual Band also means that the router, when both bands are running, can give, in your case, full connection speed to two devices before splitting its output. your dual band should give 270/8 or up to 33mb/s which is well within the wireless g 54 mb/s range, but of course your not getting those speeds unless your ISP provides you with it.
The N speeds are for wired connections, and whether you have 10/100 or gigabit 10/100/1000 ports on the router and devices. you wont see 150mbps which is N starting speed, or 300 with the top end, with wireless.
