I changed my Thomson TG585 v7 to a TPLink WR8960N. The 585 was fine, I just wanted decent N speeds, which I now have.
However, my laptop loses wireless every now and then. maybe once a day maybe once every 2 or 3 hours. Same with the other laptop. The modem is in the same place, on top of the desktop tower which is usually not running. I did change the channnel to 1 and the bandwidth setting to 40Mhz. Other than that it was a swap out. Most of my devices were set to a static internal IP, but currently they are all on automatic.
The wireless light on the TPLInk is still on green when this happens. The laptop shows me it that the TPLink is not there, until a minute or so when it turns up again.
Laptops are both Win 7
