Hi,

Here are the stats before my questions:
I have a 1955 ranch wood frame house--wired computer (with modem) is in the center.
The wired internet speeds are 250 Mbps (Win 7--self built 10 years ago)
The two wireless devices are a brand new HP laptop and a self built desktop (6 yrs old?) with Hawking wireless adapter. Both Win 10.
They are no more than 40 linear feet and 1 wall from the wireless modem (Time Warner, just upgraded)
The best wireless speeds attained are about 40 Mbps. Today around 13.

Unless you see an obvious problem, will a range extendor improve speed/performance?

Any other suggestions?

Thanks for your help,
Don
