On Friday night I installed a linksys N router, WRT300N. I had no problems with the installation. The first wireless piece of equipment I tested was a Dell latitude laptop with built in wireless adapter, with max capabilities of a G network I believe, and it worked with no problem at all. On Saturday, I purchased and installed a Linksys Wireless-N PCI adapter, WMP300N. Right off the bat I had problems. First, an error message popped up saying that the software did not pass the Windows logo test and that installing it may cause harm to the system. Knowing that Linksys is a reliable company, I continued anyway. Once everything was installed, I immediately noticed a problem when trying to access the Network Connections in the Control Panel. I was met with an error message: "An error occured while Windows was working with Control Panel file C:\WINDOWS\system32\netsetup.cmp". This, however, didnt seem to be too much of a problem unless I tried to access that control panel file. So, I know the PCI card is installed correctly at this point. In device manager it is recognized and says it is working properly. The Linksys software would then go back and forth from saying it was connected to the network, to saying it could not communicate. The signal strength indicated was only about 40%. Even so, the computer would not be able to acquire an IP address. I then decided to pull the antenna around a corner in the house and now it will connect to the internet and get an address. However, this address will randomly be lost and come back, leading to a very unstable connection. The laptop with Wireless G network adapter seems to work better in the same location, albeit with a very low signal strength as well. The desktop PC is probably about 125 feet away and up one floor. My question is..isnt wireless N supposed to be able to handle this distance easily?? Is there something I need to do on the router to increase the range? Does it have something to do with the channels (Currently set on channel 3)? If anyone could give any advice or recommendations I would greatly appreciate it. When you spend $230 dollars for a wireless system you expect it to work better than this. Thanks.
