I have a Acer Extensa 4620Z laptop running Win 7 Home Premium that connects to a Linksys wireless extender. I also have a Dell net book with Win 7 Starter that connects to the same Linksys network without the extender.I have trouble connecting to the Win 7 Homegroup. If I remove the extender and have both computers connecting to the basic Linksys wireless connection, Homegroup works. The extender has the same network name as the Linksys wireless conection. Does any one know how to fix this problem?
