Ethernet (modem/router) + Wireless Connection ??

I have an ADSL router/modem that is connected to my PC via the ethernet
port. I want to use this to connect to the ethernet.

ALSO I have an external hard disk connected to a wireless router.

However, using both at the same time......

If I have the wireless disconnected, I can see the internet.

Once I enable the wireless - I can see my external disk - but I can no
longer see the internet
(the ethernet port is OK i.e. active).

I guess the problem is that I seem to have two "gateways" and this is
confusing XP ?

As soon as I turn the wireless off - I can see the internet again via
the ethernet connected modem.

Any clues please as to how I can get both working ??

Thanks.

Hi

You probably configured the Network Drive and the Wireless on a different
subnet.

Example, Router and Wire 192.168.1.x, Wireless and Network Drive
192.168.200.x

Make sure that all the Network devices are configured on the same Subnet.

192.168.NNN.x (NNN=subnet number).

More like the other way around - the OP has two separate networks.
The wireless network for the internet connection and a separate wired one
for access to the NAS drive.

If the wireless router is set with the same IP range of the network hard
disk, then the PC won't know where to route the traffic as there are then
two network cards (wired and wireless) that look like they are on the same
network.

The OP needs to do one of two things.

Change the IP address of the external hard disk, or connect the hard disk to
the wireless router (But still may have to change the IP of this, if it
clashes with the router.

OP - when the wireless is on, and you can connect to the internet, what is
the IP address of the PC?
(Start, Run, type in cmd and press OK
type ipconfig and tell us the IP address displayed here

Now do the same with the wired connected, and the wireless tuned off.

Sparks...

Thanks for reply.....I think you are very much on the right track...
(just one thing - the hard-disk is connected to the wireless
modem/router)

With wireless off (all works):

IP address 192.168.1.2
Subnet mask 255.255.255.0
Default Gateway 192.168.1.1

The above defualt gateway is correct - this is my modem/router that the
PC is connected to via ethernet.

However, when I connect the wireless....

IP address 192.168.0.2
Subnet mask 255.255.255.0
Default Gateway 192.168.0.4

The Gateway IP address is now the wireless router - this is NOT
connected to the internet, just the hard disk. Also PC IP address has
changed.

So - how do I keep the Default Gateway address constant ????

Thanks for help. Going nuts.

There's your problem. What you need is for the NAS box to be connected
to a wireless bridge (often called 'game adaptors' - they're an RJ45 to
wireless gateway, and turn a wired client into a wireless one) which in
turn connects to a wireless access point (note: *not* a router) on your
main network.

You *can* achieve what you're looking for with a wireless router, but
it's not easy. Nor is it guaranteed to work.

Sell the router and use the money to buy a wireless bridge and a
wireless access point. Alternatively, sell *both* routers and buy a
wireless modem/router with built-in switch (for your internet
connection) and a wireless bridge (to connect the NAS to the network).

"If Ace Books ever came out with an edition of The Bible, both books

Chaos" and "The Thing With Three Souls." - Terry Carr

could he turn the DHCP off on router and set its IP manually for router from
192.168.0.2 to e.g. 192.168.1.5
and set his network hard drive manually to IP to 192.168.1.6
and let his router/modem set IP as it does now for his other couple of PC's
etc.

Well I have a similiar configuration:

Cable Modem -> (WAN Port) Router 1(LAN1 port) -> (WAN Port) Router 2

I have been trying to get this configured correctly yet untill now no
succes. What I've heard and read this setup is difficult to configure
because of the double NAT (2 gateways). Some say it's impossible (I say
"challenge", I h8 the word "impossible" :-)

As you connect this way some say it will give deteriorated performance
in relation to the total "internet" bandwith for the connected devices
on the 2nd router. With this way I mean from lan to wan. As I will
endure the possible loss of bandwith in exchange for the abillity to
use the routerfunction instead of making it into a dumb switch when
connecting LAN to LAN. And for keeping all 4 LAN ports available for
use.

I have tried a few things among the one mentoined above yet when doing
this I have to shut down the DHCP server abillity of the first router
altogether and I don't want that :-(

Another thing I tried which I thought would have the best change is to
use the DHCP servers on both routers yet set the DHCP ranges outside
each others range e.g. for
the 1st router: 192.168.1.1 as IP for DHCP server and range 192.168.1.2
up to 192.168.1.50 and
the 2nd router: 192.168.1.100 as IP and range 192.168.1.100 to
192.168.1.150

Yet when I do this the connected pcs on the second router can't connect
to the internet and when I look at the first routers attached devices I
see that the 2nd router has been given IP 192.168.1.100 (the private IP
for the DHCP on router 2), router 1 should have given the router
192.168.1.3 yet as the logs shows it doesn't do that :-s
Does anyone have any suggestions why this happens?

For ppl looking for an easy fix and don't mind that the $xx router is
working as a $x switch and can suffer the LAN port on the 2nd router,
just connect router1 lan1 port to lan1 on router 2 with a cross cable
(most SOHO routers don't have DMX on the lan ports only on the wan
port). This should also fix and sharing problems between any of the
connected devices. The 2nd router would work as a router but as a
switch/hub.
