Q: Anyone else have poor WiFi reception on Mid-2012 15" MBP with Hi-res screen?
Tried a new AirPort card, no difference. WiFi reception is half, at best, of any other Mac. My wife's mid-2010 get's twice the reception. As do the hundred of other Apple devices I service, my iPhone and iPad Pro mini.
Is there something about the antennae in this hi-res screen? It's been this way since I bought it. Simply madding as a tech. At least I know if my laptop can connect to WiFi, pretty much anything can.
Mid-2012 2.7 i7 with 1GB VRAM and hi-res display.

Took the screen off and looked under the clutch cover. All 3 antenna wires were severed in the same spot. Looking at where the strain points are and based off the many other mid-2012 uni's having the same problem, it appears to be a design defect.
I bought 2 new antennae with wires, used one to replace my defective one and all is good. The other I'll keep for when the antenna wires will undoubtedly sever again.
The unfortunate bit of the whole thing was upgrading to El Cap as part of the troubleshooting. Got sick of waking to black screens so reverted back to Yosemite.
