Problems with DHCP IP Addresses conflct

Hi there:

here's my setup which worked fine for the first 4 months and now not
sure what changed but things have gone a bit awry!

My ADSL Router (D-LINK DSL 300G) is connected to my Linksys (WRT54G)
wireless router. I have then got a cable that runs from this wireless
router to a BEFSR41 Linkysys router (my work gave me this, and insisted
that I use this, and not the wireless router for my connection)

I have 2 laptops and two desktop computers. One desktop computer is
connected directly to the wireless router, while the other is connected
to the BEFSR41 router.

The problem is that I am using the "automatic DHCP" setup on my
wireless networks. And the computers end up fighting for the same IP
address. Also for some reason each time I close the lid on my laptop,
and open it again, it loses the nwtwork connection and I have to
disable and re-enable the wireless connection for it to work again
(even thought it constantly tell me that everything is fine, and the
connection is 'excellent'). If I try assigning fixed IP addresses on
each laptop, they continue to have an 'excellent connection' but I
cannot browse the internet or do a ipconfig....

I am running windows xp on both desktops and on one laptop. the other
is a Mac OSX Tiger.

I am really frustrated and hope I have provided all the details
necessary for someone to come to my rescue!

Thanks,

Jessica.

Make sure only one router has the dhcp server enabled.

you only need 1 router not 3.

1 adsl router + wireless access point is all you need,

get rid of at least one router and make sure dhcp is only running on
one as the other poster said,

To simplify it, the D-Link should have DHCP enabled and should be the
gateway device.

This WRT54G should be converted to wire/WAP switch and the SR41 also
converted into a switch with both using the D-Link as the DHCP server and
all machines connected to either of the devices obtaining an IP from the
DHCP server on the D-Link or using an static IP on the D-link.

The principles of connection of connecting routers together in the above
solutions are the same no matter if wired or wireless routers or what
brand names they are. You'll just substitute the D-link when pointing to
the gateway device.

The routers have a built-in switch.

If you do what's in the link to configure the other routers, your IP
conflicts will go away.
