Unwanted piggybacking of DG834GT V1 router

[skunkydog]

I have a standard Sky provided router DG834GT V1.03.87 and have found that despite having all the wireless security options correct a flatmate is plugging his Netgear dg834 v4 into the ethernet port on my router and able to wirelessly hack into my ISP.It is difficult to see when he is plugged in as his router does not show up as a connected device.Somehow he by-passes all my security/firewalls etc and hooks straight through to the internet.How can i stop this hacking

if you mean he is connecrting via ethernet to your router by a pc or router to give him wireless then that cannot be avoided, you could change settings so only your pcs connect, but please elaborate

If he is pluggin his router in you couold go into the router and turn on MAC filtering, enter only the MAC for your PC and then change the password on the router. Can the router be secured somewhere that he cannot access?

and turn off DHCP on your router, after giving your PC an IP in the range, so his router won't be given an IP...

or burnn his computer?

and turn off DHCP on your router, after giving your PC an IP in the range, so his router won't be given an IP...

It will not stop the router connecting if it is given an IP address in the Sky routers range. To stop this you would also have to change the IP address of the Sky router to something like 192.168.100.1. and keep this address secret.

A better way would be to upgrade to Unlimited and tell your flatmate if he wants to connect he/she will have to share the cost.

or throw his router out the window thus elimating the physical connection.

Give your housemate a good hiding to stop him doing it in future...

I'm being serious.

It is a waste of time posting when the OP does not even bother to respond.
