Teamviewer 15 WOL problems

[foxxyman]

I swear I've set up everything right. Using Windows 10 Home, a Linksys E7500 router and Teamviewer 15. On the router, I set the DHCP Reservation, and port forwarded port 9 to target PC's IP using UDP. On the target pc, I set the IP to the one I entered on the router, and the subnet mask to the router's subnet mask. I set the Default Gateway as well the DNS server to the routers IP address. The second DNS server I set to 8.8.8.8 since there isn't another DNS server. Finally on Teamviewer, I put the target PC's IP address in the address field, and set the port to 9. The target PC can still access the internet. I think the the target device address that I put down in teamviewer must be wrong, but I don't know how else to do it. I can go into the Teamviewer dashboard on my laptop and android phone, and press the wake up button, but it does nothing.

What do I need to fix?

Is anyone else having these problems?

Might I change programs, if so what one?

First of all - I don't know what TeamViewer has to do with WOL, but ok - any program can wake computer.

I assume that you want to wake your computer (from shutdown state) if you're outside your home. And I assume that you proper set both - BIOS and LAN card settings to allow wake from power off.

So my answer is, based on my experience - Linksys routers are worst choice if you want to WOL your computers.

Basically, when you computer is turned off, your router keeps information about MAC address (which is important for WOL) and which computer on your network uses that MAC address. But it keeps that info for +/- 2 minutes only then clear that information from ARP table and then your router no longer know what computer you want to wake.

You need something called ARP binding. Only TP-Link routers have built-in that functionality (if we're talking about standard home routers, not some expensive solutions for business). Other routers have some workarounds - some of them, like Asus or some Netgears, allows you to bind IP with MAC using telnet (but after restart router you must repeat whole procedure). Others, like Linksys / Cisco home routers, don't allow you to bind IP with MAC in any way and always use dynamic binding.

That is why I'm using TP-Link routers both - in home and in workplace.

 

You may check if you proper configure everything by trying to wake your computer 20 seconds after shutdown - then even Linksys allow you to do that.

 

For WOL you need - external IP, MAC address of computer you want to wake up and port. On computer you need to configure wake on power off ability in BIOS and in LAN card (this is most important). Sometimes, in case new intel lan drivers, you need to install separate tool for access to complex lan card configuration (Intel PROset Adapter Configuration Utility).

 

Take note that if you experienced power loss sometimes, and you want still have access to your computer from outside, you should setup another option in BIOS - what happens after power loss - set it to power on, because if computer stays off after power loss, you'll not be able to wake it, since it was not listening for WOL packet anymore.

I forgot to mention that I set up the bios, and the lan card. So basically since I don't have a TP-link router, I can't get any PC on my network to wake up remotely.

TP-link or Asus or some Netgears and maybe D-Link. If you can wake your computer from outside one minute after shut down (for example using your smartphone and wol program) then you have configured wol proper and problem is with your router that have no possibility to arp binding.
