I setup my extender and have moved it upstairs in my house.

If I connect to my extender while upstairs I get around 180Mbps but if I connect directly to my router I get almost 400Mbps.

If my extender is receiving it's signal from the router (at 400Mbps) why is it only giving out 180Mbps?

I have the extender there to extend the signal up to my attic room but it's only giving a marginal increase on the attic over the router WiFi connection.

Can you give me any advice on this as speeds are very slow from this extender.
