Wifi detects nearly no signals yet cant connect.

So, My laptop will see 1-2 wifi signals (I live in a large neighborhood so on all my other devices I see 10-15 networks). Occasionally my own network will appear and if i try to connect to it all I get is "unable to connect". Ive tried troubleshooting and all I've gotten is "Connect to a Network" Ive tried

  • Restarting my router
  • Restarting my laptop
  • System restore
  • Done multiple "Fixes" with CMD. No changes from that
  • tried updating the drivers (didnt work, no new software)
  • multiple different troubleshooting
  • making sure the adapter is enabled

Nothing has worked so far. I know its not the card because networks will still come up from time to time. But it will come up with 1-2 bars even when the router is in the same room.

Does anyone have any info/fix on this? or is my old laptop finally dead at this point? Thanks

Check to see if the two antennae (white and black cables) are securely plugged into their respective Wifi card connectors.

Here is a link to the ifixit repair guide for the WiFi card in your laptop. It is handy because the image in Step 4 clearly shows the two antennae cables (in the red box) which are connected to the card. (click on the image to enlarge for better viewing)
