wifi problem

so guys i have this problem,

i have to 2 routers in my home:
netgear wndr2000
netgear wndr2700

the 2700 is downstair and the 2000 is on the 1ste floor.
the problem is that if i am downstairs the wifi works but it pretty slow and alot of dips in speed, also on the second no one can connect with it and if it does there so on internet, my rig is on the wndr2000 with cable so it works

is ther a way so i can let them work together or something??, because it starts to botter me alot and i can't enjoy 50mbps on wifi from my ips

thanks for reading

 

Ive never heard of a WNDR2000 or the WNDR2700. Check again

Also I think you mean your connection is 50 MB/s not 50 mbps = 6.25 MB/s ?

The fastest possible wireless speed is about 20 MB/s

Also how do you have them connected? If your running two routers on the same network one needs to have the dhcp server turned off
