MBA - WiFi range shortened significantly after tightening hinges

The hinges on my Mid-2013 Macbook Air 13" were loose so I followed instructions on how to tighten. Disconnected the display cable, webcam cable and the pair of wifi cables. Hinges are fine now but the Wifi only works when it is very close to the Wifi source.

The wifi cables don't seem to be damaged. I removed the wifi cables altogether and I don't see any networks if I do that obviously. But after reconnecting the cables, I do see the wifi networks but can only join them when I am really close to the router or phone (in case of hotspot).

Its like the wifi's range is drastically gone down. What could be going wrong? There didn't seem to be any visible damage to the wifi ports on the logic board or the cable throughout.
