I wouldn't like that to happen because when it gets to 1 Mbps it gets slow (even though) the signal strength is "excellent"

I have a wireless connection. The router is upstairs and my pc is downstairs. Usually at the beginning when I first turn on the pc, the speed stays at 1 for 10 to 15 mins. then it gets in good shape (54 Mbps), but then again throughout the day it sometimes goes down to 1 and varies between 1 and 11. Then it gets back to 54 and I am happy again. It has been like this for month now.
