What could I do about this?

I've checked the coveerage map and it appears that my house is about 150 to 200 meters outside the coverage zone in my area. As I have a 2 story home would some sort of external aerial hooked up to the wireless modem fix the coverage problem.

It's more about signal strength....

As the signal goes out... the further from the base the smaller the signal.
You would need a 'booster' more than a larger aerial.

I appreciate your response
