I've got two routers connected via ethernet on two different floors of my house, both with the same SSID, and identical security settings.
When connecting via ethernet to either router, all computers can see each other. E.g. basement-1 can ping secondfloor-1, and vice-versa.
When connecting via wi-fi, my Windows 10 machine, which is connected to the router on the second floor, cannot see any machines in the basement. This problem does not exist for other devices (e.g. OS X, iPad, or Android tablets).
Some additonal informaiton based on questions so far:
- To test, I renamed the router on the second floor to a new SSID. This ensured I was not actually connected to the basement router
- Network setup is as follows:
- Basement Router: 192.168.13.2 (stock D-Link)
- Second Floor Router: 192.168.13.8 (DDWRT)
- Windows 10 machine: 192.168.13.116 (I have tried both static and DHCP IP - no difference)
- NAS connected to basement router: 192.168.13.150
- Printer connected to basement router: 192.168.13.50
- Computer connected to basement router: 192.168.13.100
- ROKU connected to second floor router via Ethernet: 192.168.13.106
- Ping tests:
- Win 10 on second floor router ping basement router via wi-fi: Fail
- Win 10 on second floor router ping basement computer/printer/NAS via wi-fi: Fail
- Win 10 on second floor router ping google.com via wi-fi: Success
- Win 10 on second floor router ping basement router via ethernet: Success
- Win 10 on second floor router ping basement computer/printer/NAS via ethernet: Success
- Win 10 on second floor router ping ROKU via wi-fi: Success
- Win 10 on second floor router ping google.com via ethernet: Success
- iPad on second floor router ping basement computer: Success
- iPad on second floor router ping basement router: Success
- Computer on basement router ping Win 10 machine on second floor router via wifi: Fail
In a nutshell, it looks like the Windows 10 machine specifically cannot see anything connected to the basement router, but it can see the internet. It can also see devices connected to the second floor router (e.g. ROKU). Second floor items can also see basement items (iPad works okay via wifi; ROKU works via ethernet - both can access the NAS in the basement).

Any suggestions on what may be happening? I'm confident the router setups are okay because everything seems to work fine with other platforms; the problem seems to be specific to the Windows 10 machine on wifi.
It looks like there is something materially wrong with both routers in my house; the issues above seem to resolve if I do a full power-down (i.e. unplug), pause 1 minute, and then re-power everything, starting with the basement router, then the second floor router, and then re-enabling WiFi on all devices. Both routers are older models; as a next step I may try installing DD-WRT on the basement router and seeing if that fixes anything.
