Re-enable IPV6 and the ISATAP adapter then connect wirelessly when you're right next to the router. Go to speedtest or surf the internet for a while and see if you still disconnect. If you don't disconnect, I'd probably blame the problem on a wireless interference issue.
Fred, I re-enabled the ISATAP 6 and the IPV6 and sat the laptop about a foot from the router. When I tried to connect my wireless network, it wouldn't connect. I tried about a dozen times, and eventually copied the error msg. It finally did connect, though. I did the Speed Test, and surfed around for about 10 minutes. The laptop did not disconnect during this time.
CyberMan, I went to the Intel site via your link, and it confirmed that I have the current version of the Intel driver.
Now the original xirrus screenshot i know it is deleted showed good signal where was the Laptop then was it near to the router?
The laptop was upstairs when I took the original screenshot; so, no, it was not in front of the router.
I'll post a new Xirrus screenshot for you, taken upstairs earlier today (while my computer was connected wirelessly, upstairs away from the router). Something I noticed, I was away from the computer while the Xirrus was on, and the signal strength didn't move on the graph. When I got back to the computer, and moved the mouse around on the Xirrus page, the signal got weaker. You can see the straight line where I'm not at the computer, and then it starts to drop when I start to do something on the computer (that wasn't internet-related). This might be normal, but I thought I would mention it.
Agree with Fred that a lot of concrete between your router and Laptop is going to degrade the wireless signal significantly.
I should clarify that the concrete foundation surrounds the basement, but the floor (between the upstairs/downstairs) isn't concrete, so the concrete isn't between the router and laptop. I drew a little diagram of the layout. The laptop is practically sitting right above the router when I'm upstairs, and the floor is your basic wood floor with carpet over it. So I don't see how the concrete can block those waves. And, as you can see from the Xirrus shot, the connection is excellent when I'm upstairs. In case the print isn't readable, the blue x is the router. The green x is the laptop (hard to read, but I said that the waves are being sent up through the floor... I think). The room surrounding the blue x is concrete. Maybe TMI... :sleep2:
can i ask when your Laptop was close to the router using the wireless did it disconnect.
The only problem I had today was getting the laptop to initially connect when I was close to the router. It didn't disconnect after I finally connected, though, but I was only on for about 10/15 minutes.
Leave the isatap adapter disabled it is not required for normal internet connectivity using ipv4.
Do as Fred advised and test the connection with a long ethernet cable so the router is upstairs and see what the wireless signal is like then and post speedtest results.
I won't be able to do that right away because I don't have a long ethernet cable, but I will get one. Thanks for your input CyberMan.
