hey guys, would like to ask some question for all of you.

how crappy is DIR-615 that has been provided by TM?It seems ok when i'm using it with pc (normal surfing, youtubing, dowloading) but when i playing online with xbox live, i can't get full bars. sometimes i can get three bars of signal(yellow color), 4 bars (green - once in a blue moon) and one bar (frequent- red). playing black ops can be very frustrating because you have already shoot the opponent with full clip yet they still running around and kill you back.

  I'm thinking to change my router to a better one but i'm not sure whether i'm going to ditch the DIR-615 completely and get Mikrotik switch with good router or just do the VLAN tagging with DIR-615 to another router. any significant improvement for these 3:

1- xbox>>DIR615 (crappy)
2- xbox>>>Router>>>DIR-615 (any improvement?)
3- xbox>>router>>mikrotik (any improvement?)

i'm quiet satisfied with the speed i got when using DIR-615 with pc, that's why i asked if any of you can give me the answer for my problem. Thanks.
p/s: my xbox is wired to DIR-615, not wireless.

p/p/s: i'm on vdsl, not ftth. yeah i know vdsl is not that good but i would be thankful if i can at least get 2 bars frequently.
