I originally posted this question out on the Networking forum, but got no response there so I'm hoping that one of the Windows 7 experts may be able to shed some light on the problem.
I just finished putting together a new computer using an ASUS B150M-A D3 motherboard and Windows 7 64-bit OS at the SP1 level. I want to connect it to my home network. I have a Netgear router that supports 4 wired Ethernet connections and 8 wireless connections. I have my other desktop computer connected to it with a wired connection and it was the one that I originally used to create the Homegroup several years ago. I also have 3 ROKU players, one Logitech Revue box, a Kindle Fire tablet, a laptop computer, and a printer connected wirelessly. The printer is also connected directly to the desktop computer via a USB cable. At the moment, only the ROKU players and Revue box are active on the wireless.
I plugged the new computer into the back of the router with a wired connection and found that I could access the internet without any problem. I then opened the Networking section of Windows 7 and attempted to join the Homegroup. When requested, I entered the Password that I use for all of the wireless devices in the Homegroup. I received an error message telling me that the password was not correct. I went to the original desktop computer, opened the Networking section and then selected "Show or Print Password". The password that was displayed was not the password that I use to admit wireless devices into the Homegroup. It appeared to be a group of 10 randomly selected letters and numbers. "Okay, no problem, if Windows says that this is the Homegroup password, that's what I'll use." So I went back to the new computer and used this password to try to join the Homegroup, but I still received the message that the password is not valid. I checked the password carefully for errors, but subsequent tries still resulted in the same error message. Can anyone shed some light on why, when I'm using the correct Homegroup password that I still am told the the password is not correct.
Thanks in advance.
