Please help!!! On 3rd Nexus 5, having same issues. Phone support is abysmal :(
I am having ongoing issues with the wifi on my Nexus 5. To the point I've received my 3rd one from RMA, but still have the exact same issue. At first I thought it may have been a hardware issue with the phone, so I RMA'd it. When I got my second and had the same problem, I started to not think it was a physical defect with the phone. The odds of getting two phones with the same issues would be astronomical. Now, on my 3rd, and still have the same issue. Every time I try calling and speak to phone service reps, they really don't know anything, and based on the questions they ask, or troubleshooting steps they suggest, lead me to believe they don't even understand the issue I'm trying to explain.
The wifi on my phone seems to "freeze", or stop working, stop scanning, something throughout the day. My day starts with my phone connected to my home wifi network. I leave for work, and I can watch my phone picking up random wifi signals on my drive. I get to work, and it picks up 8 wifi networks. None of which I've connected to. When I leave work 8 hours later, my phone is no longer picking up wifi signals, and won't scan for new ones. I get home, and it still says the 8 networks from work are in range, even though I'm miles away.
This is how my wifi list should look sitting in my living room.
It has my network that it is connected to, as well as it picks up 4 of my neighbors networks.

Those are the 8 work wifi networks, which are miles away. It still says they're in range. You can see the last one cut off on the bottom, is my home one that says it's out of range.
I can hit the 3 dot option button, and choose "Scan", and it won't rescan. If the only issue was that it didn't pick up my network, I could see it possibly being an issue with my home network. But the fact that it still shows 8 networks that are out of range, as well as the fact it won't detect any network, mine or my neighbors, kind of rules out that it's an issue with my network.
Turning wifi on and off won't fix it. However, power cycling the phone will, or if I toggle airplane mode. But I shouldn't have to do that every day when I come home.
With my most recent Nexus 5, when I took it out of the box I didn't do a single thing to it, aside from turn it on, and manually put in the info to connect to my home network. Not a single app was downloaded, just to rule out it wasn't something I was installing on the phone. I absolutely love the Nexus 5, it's probably the best phone I've owned. But I am at my wits end with this issue.
