I have a very weird issue. I have a wifi printer (Canon MX870) in my home network. In this same network I'm using my Playon HD2 and my NAS (Synology DS1511+).

If I have the printer switched on then the Playon cannot find the NAS through the network on its IP address. Instead, it finds at this IP address the wifi printer and shows the folder "canon memory" as the only folder available at this IP.

This is really weird because I have set in my router a "reserved" IP for both the wifi printer and the NAS (the latter is connected with a LAN cable to the router). These IP addresses are of course different.
So now my NAS has internal IP address xxx.xxx.x.45

In my Playon settings I have configured a shortcut for this particular IP address (so not device name, but based on IP) xxx.xxx.x.45 so that I can connect to the NAS. However, when the printer is switched on it will find the printer instead, even though the printer has IP address xxx.xxx.x.16

From my laptop and my desktop PC (both in the same network) I can reach both the printer and the NAS at their IP addresses perfectly without any conflict whatsoever.

I have already tried giving both the NAS and the printer a new reserved IP address (configured both in the router as well as the devices). The result is the same, perfectly reachable by desktop and laptop using their new IP's but the Playon still gives the same conflict.

As soon as I switch the printer off, the NAS is found by the Playon using the same IP address (xxx.xxx.x.45) and shortcut which results in the conflict when the printer is on.

Anyone with ideas?

Assign a static IP address to devices with a dedicated function in your network (print server or printer, file server or NAS) outside the address range that your DHCP server uses for dynamic IP addresses.

Did you ever find the answer to this? I have the same issue.

Static IP addresses have already been allocated to the individual devices and as I have a different NAS to you but the same issue arrises with the AC Ryan and a Canon network printer. I can't just leave the printer off as it is also the fax machine.

Can you post your LAN IP address details please, including subnet? The only obvious thing I can think of that would cause that sort of issue is that the subnets are wrong between your devices, or something is buggy with networking on the Canon printers.
