Hi all, just seeing if anyone has ever seen this, or has any suggestions.

I have 2 Unifi A/P's at opposite ends of the house.  If I have my laptop at 1 end of the house (so it connects to AP 1) and another machine on AP 2, I cannot RDP from one to the other.  If I move the machines to be next to each other (and so on the same AP), RDP works fine.

I know some devices don't like switching between AP's as Unifi doesn't do seamless handovers (sorry, I don't know the correct terminology here), but I wouldn't have thought it would affect connectivity between devices.

Thoughts?

That's definitely odd....the UAPs are both hard wired, not wirelessly uplinked? You don't have any guest policies setup on the wireless networks? Just one SSID or several? Can you ping the PC in question when it's on the other UAP?

Both AP's are hard wired to the same switch (3COM, fully managed, no VLAN's), nether is PoE; both are in injectors.

No guest policies, and just one SSID.

I didn't try pinging this time, but last time this happened I couldn't ping the machine, and just rebooted it, which I happened to do after I moved it.  I only just though about the location of the two machines in relation to each other now.

To clarify:

1 laptop is my personal machine (Surface Laptop 2)
1 laptop is a work machine, configured for a corporate network, Windows 10, and uses something to allow connectivity back to the office lan without an explicitly creating a VPN connection (something like a IP6 tunnel???)

When connected to the UAPs are you getting an IP address from the same range/DHCP server?

 

Is there any other connection between the computers, like can they ping each other?

Are you trying to RDP via IP or PC Name ?
Can you ping ?
ipconfig /all : is gateway & DHCP server the same on both PC's ?

 

try Team Viewer instead

I would suspect a routing problem caused by that connection to work.  What does the routing table show for that PC?  Where does its default route go to?  Use the command "route print" and have a look.  Compare the routing table with the other device.

Is it not something dumb like when on AP1 your on a private network and when moved to AP2 it has gone to a public network and different firewall rules kick in?

 

My first go to is the network location settings then the firewall.
