ADSL wired and wireless nw question

By mayurdk ·
Hi,
I have a ADSL Dlink modem and a netgear router. I have connected them in the following configuration. ADSL ethernet out goes to one of the netgear router ports (not the uplink port). One desktop wired connected to the other network port. One laptop connected to netgear wirelessly. I have given following IPs. Dlink - 192.168.1.1 , Netgear 192.168.1.2 , Desk 192.168.1.3 and laptop 192.168.1.4 Infact I have DHCP enabled on bothe dlink and netgear. I can access the internet but it keeps going down often. That time i cant even ping 192.168.1.1 . At all the time I cant pint 192.168.1.2 or access wireless modem for ongifuration. Can you help me set up the network properly. I see one strange problem very often. Suddenly I get disconnected from the internet i.e. browsing stops but if I am downloading something, it keeps continuing, doesnt break.
(I am not using the uplink port because for some reason netgear fails to connect to internet then. It detects the internet but then fails to connect).

In the configuration you described above, you have two active dhcp servers, and they are both on the same physical segment since you have the ADSL modem on the 'inside' of the netgear router. (conflict conflict).

By not using the 'uplink' port of the netgear, you are using it as a hub/switch. therefore you need to disable dhcp in the netgear router since the DLINK is doing DHCP for you and will provide it for all workstations.

If the above does not help, then:

Do things work correctly if you just hook a PC to the DLINK modem? By default the modem should give the PC a DHCP address. You may need a crossover cable to make this work. There are known problems with DLINK ADSL hardware losing connectivity after a short time (need to upgrade firmware), see: http://www.dlink.com.au/tech/faq/modems/dsl200.htm

Thanks robo_dev. I realised that they need to be on different subnet if I connect the ADSL to uplink port. Also I have now DHCP only on negear router. Thanks for the reply. I helped me well.
Regards,
Mayur.
