sounds like your router is running on a low expiry date schedule. see if you can change it. Also, set nao and the v4 a static ip(an ip that doesn't change).

Ya, your going to have to get a better and newer router before the V4 arrives at your house. I had this same issue when I was setting up the V4 when I got it. Read through this thread of mine:

Connecting To Two V4 Ezb's

By the way, You Belgium's really kicked our USA butts in the World Cup race today.blush I really shouldn't be trying to help you now but it's only soccor.

the router is just 1 year old.

dave maybe we where lucky.thats all.

can the flacher be worn out.i got this one for more then 5 years?

I think technopro is probably right on this one. @nomad18.08 are you using dynamic or Static IP addresses? I would use a static IP address instead of a dynamic address if you are keeping your robot in your house, but you need to make sure that it is assigned an IP address that is outside of your dynamic range of addresses.

All of the information will be available through the interface to your router. If the IP that is assigned to your robot is within the range of addresses that are assigned to your DHCP scope or range then it is going to be dynamic. You wont be able to use the normal commands in windows to tell, but there may be something in your NAO that allows you to set the IP to be a static IP address.

The thought is that the DHCP server is dropping your IP due to a very short expiry time. If you have a static IP, the DHCP server wont drop you because that will be the specific IP address that will always be used for that device and the DHCP server wont have anything to do with that address.

Your router could also be set to reboot on a nightly basis. I have my WIFI Access Point set to reboot weekly.

hi.this is a lot for me.the nao works great whit wifi in choreograph. so he's somehow connected whit the wifi. but to be able chown nao web page he dont. your right about wifi dropping out problably acery day. so this is all new to me.how can i set that it will stay .

thanks.

I think what you are looking for is in the router itself. The router should have a web interface to manage it. This can get pretty complicated if you haven't seen it before, and unfortunately I cant read Belgium.

I wish I could help but it is going to be very hard to do so. you might set your router back to the default setting and see if that helps. By default, it shouldn't be issuing really short timeouts on for IP's. Does this happen at the same time every day or at random times throughout the day?

am not chore.but the web page off nao is avery day gone. the router has never changed .for the nao i just need to set ip in browser. it worked for tree times in a row,so its possible that aldebaran done some changes, i dont see now..

Do any other devices on your network go off on a daily basis?

Do you have a tablet, laptop or Cellphone that you could do some tests with? For example, you could connect your cell phone to your wifi. When you notice that the NAO web page goes off line, look at your cell phone and see if it is still connected to Wifi. I think what is happening is that when the device isnt used for a period of time, the DHCP server in the router kills the connection to the device. You would know if it is the router if your cell phone behaves the same way.

If it doesn't, then you could look to see if there are any setting in the NAO. I am dont really know anything about NAO other than the videos I have watched on him. This should give you a direction to start looking.
