I have just purchased an inexpensive 7" tablet. I thought my in home modem had wifi but it seems it does not. I am not in search for the most powerful, less expensive router one can buy and so far I have seen everything from a cheap $24.99 to $300.00 and I am confused as to which would be best. I know with all the wealth of knowledge here some one can advise me. I only want to be able to go to the net w/o going on my desk top and of course read in bed. I don't need all the bells and whistle some use the tablet, just the basics.
