Solve : Cannot Connect with Wireless after replacing RAM?

Answer»

Yep , question is above, I put RAM into a Dell XPS 17 702X  and logged into Windows 7 and could not use the wireless: Only the Ethernet icon appeared looking for an Ethernet CABLE and it told me no Connections were available. When I ran the connection troubleshooting, it just told me I needed an ethernet cable plugged in. How can I get the wireless back? I've tried  taking a stick out, same problem, tried  putting the original RAM back in (4GB) . Did not help. The new RAM was 16GB and I bought the RAM after contacting DELL who knew the exact PC model when helping me. (Bought what they sold me over the phone. Currently the new RAM is in the PC.)

Thank You

This is not likely your RAM causing the issue.  I would recommend making SURE you haven't accidentally turned off your laptop's wifi.

Pages 16 & 17 will help you try to turn it back on again.

The other likely issue is that while installing the RAM you may have dislodged the wireless card or cables on your laptop.

Page 22 will show you what that looks LIKE.  I'd check and make sure the power connections are properly seated.

Best of luck!Nyako,
Please let us know if it really was the RAM upgrade.
Have you tried going back to the old RAM?

Does hardware manager show the wireless thing is active?

Seen people disconnect the antenna wire to the wireless adapter before and have this same issue. There is a button SNAP type connection that needs to be made and if this is damaged it MIGHT not be connected properly. The antenna needs to be carefully removed if removed and not cocked to the side to pop it off.

My thoughts are that the antenna wire(s) are disconnected as the most likely cause if the wireless switch isn't shut off. Some antenna connections have 2 others have a single connection.
