Lost Wifi after replacing display

I replaced the display in the Apple Watch SE. Before I put it back together it was all working. I glued the screen on and when I came back this morning, it won't see any wifi networks at all. I've restarted the watch, etc. Any ideas? I don't even know where the antenna is, but is it possible I somehow dislodged it or something? Not looking forward to taking the display off a second time but will if I have to
