Hello. Yes i did that with the first SP3 I got and it could not stay connected. Customer support said it was probably defective and returned it. I then heard Microsoft acknowledged the problem and were fixing it so I got a replacement but a different model
as well. The one with 8 GB of ram. however that had the same exact wifi problem as well.
I tried different locations, in fact even with wireless G routers it would drop the connection, it was more stable but not reliable. Microsoft then released a patch that solved most issues. unfortunately the last patch after that broke it again.
I then gave up and got the USB WiFi adapter and has been flawless since then since I am not using the internal WiFi card anymore. just for kicks I enabled the internal card today and it dropped the connection after one hour, awful. Back to the USB WiFi
adapter without issues.
Bottom line is Microsoft is not really fixing this problem or not taking ownership of the issue. users will lose confidence on their products if they can't produce something stable. like I mentioned in an earlier post, my nexus 7 has a rock solid WiFi
connection, that is a $200 machine, same for other inexpensive devices, this $1,400 machine can't even stay connected to the internet.
Do you think Apple would release their air laptop with the same problem? Something is not ok with the company.
