Wake On LAN - Stop Working After Around An Hour Sleeping?

[PizzImperfect]

Hi All,

I have a DD-WRT configured router, acting as a client bridge on my home network.
After a day or two messing around, I managed to get Wake On LAN (Although, I'm using it to wake the system externally) working.

I woke the system twice and it worked great. Though i've noticed that if I leave the PC sleeping for 30 mins - an hour... It will no longer wake.

Any ideas on what could be causing this?

Thanks,

Pete

What format are you sending the magic packet in? The one I use involve the mac address for the PC and are sent to the broadcast ip for the network.

MAC address, and if the ,255 ip is the broadcast one, then yeah me too :\

If you power cycle the machine by switching off at the wall/psu does it then boot?

Check the ARP table on the router and see if it forgets the PC's MAC after a certain amount of time has passed.

I am having similar problems,

if my laptop is left plugged in and powered it will wake on lan for about an hour afterwards but it will still be woken up by Splashtop as long as it has power

it doesnt matter if ive cut the power to it between shutting down and hitting it with the wake on lan / splashtop it also still works, i have  tried it both from the internet and locally and it seems that outside of the hour or so it just doesnt do anything,

 

what does ARP stand for? does it go by any other names?

 

might have to look into trying to view it on my router which is a Virgin router which I think is made by netgear 

 

failing that is there any way to make the ARP remember the mac address?

Address Resolution Protocol

So what you are saying is that you have a bespoke branded router provided by your ISP who is Virgin? If that's the case then yes these cheap routers/router-modems are notorious for being... well just that... cheap. As such they lack the features that the general consumer won't really use or even know about - such as a retained ARP table or VPN client/server or static routing capabilities for instance.

 

If you are serious about networking and care about such features then you really need to ditch the cheap plastic box and get a real router

I wouldn't say that it's impossible. Easiest option first then; does this router of yours appear on dd-wrt.com? If not then how are your electrical engineering and embedded software engineering skills these days?

good to know,

 

I have an old Belkin wireless g router, will I be able to run an Ethernet line to the router from the virgin super hub into the router to use the Belkin as a switch / second wireless point as long as I turn DHCP off, without affecting the super hub as it is also the modem but is connected to wired devices downstairs were it sits?

 

I have plans to do this with a dual band AC router at some point anyway but haven't got a cat5e line run yet and was nervous of other implications and a slight lack of funds to drop on a new router

I don't see why not. However once you have your ideal router you might want to consider trying to see if you can switch the ISP router/modem into modem only mode and run everything through your own router. If you can't then you can perform double Network Address Translation (NAT) in the same configuration by connecting everything to your own router and turning off every router feature you can on the ISP router/modem - DHCP, wireless and so on - except for the firewall.
