WiFi repeater, weaker signal. Can i force Win7 to connect to router?

I used a repeater to increase my signal in my garden on the other end of my house, that works perfect. But the signal strengt of the WiFi connection on my PC is lower and also my internet speed. Removeing the repeater gives a internet connetion loss (for a shrot time) so it seems like my PC's preferred connection is to the repeater (witch is further away then my router).

I can choose to give my repeater a different SIDD name so i can choose manually but i prefer the same name.
Is there any way to force my PC to connect to my router with the same SIDD? ( i have a DLink dir 655)

Repeaters are the same as a network bridge, they cut the bandwidth in half which is why I don't like them. This is why the connection seems slower to you.

Much better off with a wireless access point connected to a wired connection.

With the same SSID it's usually going to pick the connection with the better signal strength. You can choose to forget the other network which would force Windows to choose the 655.

A wired connetion would be better but from the router to the other side of my house is quite an ordeal to lay a wire.

I cannot choose to forget the other network because they have the same SSID so i'm not sure what you mean by that.
