>>>Thank you very much for the detailed answer. I suppose since the current router (which must be 2.4 GHz) works then buying even a single band router 802.11n (which will be still 2.4GHz) will improve the speed. My cable company (ISP) says that we get 12 Mb connection (I have not tested it though). This is for home use, not work, so reliability is not that important (not for my wife though <g>).
