Wireless AP & Default gateway set via DHCP

[burgemaster]

Hi.

We have one external laptop that need to have a different Default gateway to all our other machines. We can't manually set the network options as it is used in different schools.

 

We have made a reservation in DHCP and told it to give it the correct default gateway. This works perfectly when the laptop is plugged in with an Ethernet cable. Correct reserved IP and default gateway. But ...

 

...When it connect via wireless it picks up correct IP settings but NOT the specified default gateway?

 

Has anyone please seen this before?

Hmmm... What APs are you using? Is the AP giving out what it's got in it for a gateway rather than the proper DHCP options ?

 

I've just tried this. I've created a reservation with options that bypass our usual default gateway, and on our Unifi network it works as you expect it to, however on our few remaining nasty belkin units it does exactly what you're describing...

 

This might not be that useful, but it's something to think on.

Thankyou for the reply and also testing!

 

Its a Netgear AP, not a cheap one but unmanaged. I guess it is the Access point then! Thanks for testing this.

 

I will tell them that they must carry on using a cable. they only use it once a week, but I said I would see if I can sort it.

Perhaps the wireless card needs its own reservation, as it will have a different mac address to the wired card. Connect the wireless card to the network, then check DHCP to see if it has come up as a normal lease.

Good shout, but we already have both
