Hi all.

i have a wirless set up with my brother which is about 150meters away.

At his end he has broadband so we set up 2 antennas so he can transmit to my house so I can also have broadband.

He has
dlink wirless router.
IP Address - 10.1.1.1
Submask - 255.0.0.0

Minitar MNWAPB
IP Address - 10.1.1.2
Submask - 255.255.255.0

His Laptop
IP Address (Static) - 10.1.1.3
Submask - 255.0.0.0

And at my end I have my set

Minitar MNWAPB
IP Address - 10.1.1.100
Submask - 255.255.255.0

My Comuter
IP Address (Static) - 10.1.1.101
Submask - 255.255.255.0


Now I thought in order for me to get broadband through this network we have set up, we had to have the same submask. From the settings above, his submasks are different to mine. Both minitars are set up as Bridge Point – Point. I don’t know why this works but I can get broadband and when I share a folder, he can see and copy that folder to his pc.

I don’t know why this works.

Can somebody please explain it?

Thanks

255.0.0.0 will allow for that network to see C Class subnet which you have specified with the 255.255.255.0 so it will work.

Have a read of this for a brain boggle

The net is working however as you would have specified a default gateway as well somewhere in your configs with some DNS... thats why the internet traffic is routing correctly

Bottom line is of course if it ain't broke, leave it alone!

Bottom line is that your subnet's "overlap" and while it isn't a very clean setup - it will work.

Well. its was working till I stuffed around with the access point and stuffed it. Its away getting repaired now but last night I was in a curious mood so I got my brother to connect his aerial up directly to his router,
I got his working Minitar and configured it at my end.
I had the wife nagging that broadband wasn’t working so I had to get this thing going.

I played around with the settings and in the Minitars Mode, I set it to “Infrastructure” or something like that and then I was able to ping his router. Once I did that, I set the IP settings on my PC to “obtain and IP address automatically” and it takes ages to get an auto IP address (About 40 – 50 seconds) then it works.

Now the router is set to DHCP mode which hands out IP address’s. If I set a static IP address to my PC it wont be able to connect to the internet. I understand this but why does it allow my PC to connect to the internet when I have a static IP address of 10.1.1.2 assigned to my access point if the router has DHCP enabled?

This is a good learning curve for me.

When you have the router set up to serve DHCP it also passes along other information as well as an address to use. Usually this would include the default route and the IP addresses of the nameservers. The connection at your brother's hose would get these form the broadband login and then make them available to any DHCP client. If your router is a client of his and also runs DHCP then everybody get the default route and DNS nameservers.

The PC using the static route is missing out the default route and nameservers. If you want to use it with a stattic address then look at the allocated default route and nameservers in the ocnfig panel and enter the same ones manually for the static config.
