home network problem: access a computer under another router

[Mike]

Hi,

The network connection in my home is following:

1. wireless router R1 connects to the internet cable modem.
2. computer A1 connects to R1 by wireless
3. wireless router R2 connects to R1 by wireless. The operation mode
in R2 is wireless ISP.
4. computer A2 connects to R2 by wire.

Right now, both A1 and A2 can access internet. But A1 and A2 can't see
each other, ie. in A1's network place, I can't see A2.

Any suggestions to make A1 and A2 can see each other ?

Thanks ahead.

Mike

How are you sure R1 is connected to R2? This can only be done if you have
changed the firmware on one of the routers to be basically an access point
to the second router. Currently you have these computers connected to
seprated networks. Now if you connect R1 to a port on R2 (or other way
around) then turn off DHCP on one of the routers (you should only have DHCP
on one of the connected routers on a network) you could make that work.

Ex.

Hardwired:

Set IP address on R1 to 192.168.1.1 with DHCP on
Set IP address on R2 to 192.168.1.2 with DHCP off
Connect R2 to a physical port on R1 (Not Internet port)

This will allow both computers to detect each other using IP addresses. To
have both computer see each other using NetBios you willl need to change the
workgroup of both computer to the same name.

Wireless:

Set IP address on R1 to 192.168.1.1 with DHCP on
Set IP address on R2 to 192.168.1.2 with DHCP off
Connect R2 to R1 Wirelessly (this is access point mode). If your router does
not support this mode check online at
http://www.dd-wrt.com/dd-wrtv3/index.php to see if they have the firmware
for your router to make it so.

This will allow both computers to detect each other using IP addresses. To
have both computer see each other using NetBios you willl need to change the
workgroup of both computer to the same name.

How are you sure R1 is connected to R2? ...

If I shut down R1, then A2 (which is connected to R2 by wire) can not
access internet. So I believe R2 is connected with R1.

Ok, but how is it connected or is it just a fluke? What are the parameters
that you used to connect it wireless? It is not standard practice or the
default manner in which routers are shipped so there must have been some
sort of setup used to gain access. How was this achieved?

The detailed information are below:

Operation Mode: I select "Wireless ISP".
available modes are:
mode 1. Gateway: In this mode, the device is supposed to connect to
internet via ADSL/Cable Modem. The NAT is enabled and PCs in LAN ports
share the same IP to ISP through WAN port. The connection type can be
setup in WAN page by using PPPOE, DHCP client, PPTP client or static
IP.
mode 2. Bridge: In this mode, all ethernet ports and wireless
interface are bridged together and NAT function is disabled. All the
WAN related function and firewall are not supported.
mode 3. Wireless ISP: In this mode, all ethernet ports are bridged
together and the wireless client will connect to ISP access point. The
NAT is enabled and PCs in ethernet ports share the same IP to ISP
through wireless LAN. You must set the wireless to client mode first
and connect to the ISP AP in Site-Survey page. The connection type can
be setup in WAN page by using PPPOE, DHCP client, PPTP client or
static IP.

Computer A1: connected with R1 by wireless
IP address: 192.168.0.197
subnet mask: 255.255.255.0
default gateway: 192.168.0.1

--------------------------------------------------------------------------------------------------------------

Computer A2: connected with R2 by wire
IP Address: 192.168.1.2
subnet mask: 255.255.255.0
default gateway: 192.168.1.254


Both A1 and A2 can access, but A1 and A2 can't see each other. Any
suggestions ?

Thanks.

The problem seems to be that you are using the router as a bridge so I would
guess that A1 would have an address much like 192.168.1.x and A2 would have
an address much like 192.168.0.x This however will not work for one segment
does not know about the other. What you would need to do is to setup R2 as
an extention to the network of R1 where both networks would have the same
segment addresses much like 192.168.1.x. DHCP on the R2 should be turned off
and allow the IP address on R2 to be static IE 192.168.1.2 where R1 would be
192.168.1.1.

So you would need to setup R1 to access the internet normally and have R2
access R1 and get the internet only thru R1. R2 will just route any info it
gets to R1.

This will work. I have turned routers into Wireless Clients to other routers
and this will work. Let me know if you have any further probles or
questions.
