Windows – Cannot ping wired devices from wireless device

I have a small home network with the following configuration:

• 192.168.1.254 -> Gateway/DHCP/DNS
• 192.168.1.1 – 192.168.1.127 -> DHCP Range
• 192.168.1.215 – 192.168.1.253 -> Various IPs in this range are used for static IP devices.

The problem is that I have one laptop that, when connected wirelessly, cannot ping (or detect at all) wired devices. I receive the 'Destination Host Unreachable' error. The device I am trying to ping has an IP of 192.168.1.244. To be clear, I have tested with other laptops and they can ping 192.168.1.244 while connected via wireless. My iPhone also sees the device with that IP when testing using a network scanner app. It is a problem SPECIFIC to this machine. It is also specific to the wireless interface; if I use an ethernet cable, I can ping the IP just fine.

Some more details on what I have tried:

• Update the wireless card drivers (Dell wireless 1901 card on Windows 10)
• Updating Windows
• Give the laptop a static IP
• Let the laptop get an IP from DHCP
• Disable the ethernet interface
• arp -a results in wireless devices and the gateway, but no wired devices.
• Tracert also results in the 'Destination Host Unreachable' error.
• The router is a U-Verse router, I checked everywhere on the admin page to see if the device was in some sort of quarantine.
• Reinstall Windows (Not an upgrade where you keep all your files – I wiped the disk and started over)

I have checked other questions (like this one) but I know that my devices are on the same subnet AND I know that wired devices can communicate with wireless devices on my network – again, this is the only device I have this issue with. When I have a chance, I'm going to try arp -s and manually add the device and see if that works. After that, I don't know what to chalk this up to besides a faulty or dying network card.

What am I missing?

UPDATE: The wireless card supports 2.4GHz and 5GHz. I have found that if I connect to the 5GHz network, this issue is resolved. I have most devices connected to the 2.4GHz network, so I know that is not the issue.
