Not Able To decide till now, Still Stuck.....Mind want C7 but Brain resists at point out Asus.
Wish if N18U goes below 6k then it is easier to decide.
During Diwali Deal C7 goes to 6515/- where N18U - no change at 6.5k.
Go for the ASUS RT-N18U. You wont regret it. I tried 3 routers before ending up with this one.
