Compared to what you have now I would think anything would be better. Its impossible for me to say (for sure) that what you posted above would be better. I've never used it. All I can tell you is to read some reviews before you buy it.
You might be interested to have a look around here too. Real Help For Your Small Network - SmallNetBuilder Lots of info and reviews too.
Thanks mate.

I have a Dual Band Netgear WNDR3700v4 and until today, I never saw both bands available and selectable.
I'm in the process or reinstalling Windows 8.1 Pro X64 on my Grandson's Toshiba Satellite A305-S6872 laptop. It has a Intel WiFi Link 5100 AGN wireless card.
Its sees both the 2.4 and 5Ghz bands for my router and I can switch between them just by selecting and Connecting.
My Dell Inspiron 15R sees only the 2.4Ghz band and it has a Intel Centrino Wireless N 2230 card. Intel site says:
802.11bgn, 2x2, dual stream delivers up to 300 Mbps speed
Attachment 359386
