Hi. I've only had my new pc DELL INSPIRION M731R for 3 days and I'm totally frustrated. My pc won't stay online long, when operating in Facebook it keeps dropping out. Out of the 5 "bars" in strength I can only get 1. I have read and read all the issues in the forum on wireless connectivity, and the suggestions. Most identify the 15 inch in 5537. The only thing I could do was to unchecked the "Allow the computer to turn off power". I couldn't do any of the other suggestions because I don't have the options discussed. The options listed on my pc and the settings under Network are: 802.11b Preamble Long and Short (other available choice is Long Only) AdHoc 11n Disabled Network Adapter Not present Receive Buffers 256 Scan Valid Interval 60 Transmit Buffers 512 I have a new Linksys AC1900/EA6900. I'm living in a one floor house, and IF I can get a connection, it says "Limited" and then there is nothing. The troubleshooter says All drivers are up to date. I was upset enough when I realized this computer won't allow me to use the 5Ghz, but I expected to be able to get 5 bars on a brand new computer. Any help you can provide would be DEEPLY APPRECIATED, Thank you.
