Hi

Excuse me my English is weak 

I have a vx1800v router And a re505x range extender

My internet speed is 100 megabytes per second

The router gives me a speed of 98 

The extender does not exceed 65 

Even if I put the extender next to the router 

But with my old router vr400 it gives me full speed

What do you think is the problem

thanks
