My Router does not accept a gateway ip that has a subnet address different from the laptop ip address

Hi Guys,

My ptoblem is very much described in the subject line. I have a
Compusa 54MBPS 802.11 b/g Wireless Broadband router.

My ISP has provided me with an IP Address a.b.c.d and the default
gateway is a.b.x.y

Now since the gateway is on a different subnet that the ip address
provided, Windows shows me a warning but accepts the settings and my
interent works perfectly when connected directly to the cable modem.

However, when I try connecting using the wireless router, it does not
accept the ip addresses and throws an error that the gateway is on a
different subnet than the ip address and hence is invalid.

I tried various combinations, but nothing seems to work.

Can someone help me in this regard? Would be really grateful if
someone can.

Regards,
Anand.

What makes you think it's a different subnet? What netmask are you
using? Make it 255.255.0.0, and both those addresses will be on the
same subnet.

Thanks a lot John!. The router did accept the settings when I changed
the mask to 255.255.0.0

However I am still not able to connect to the internet. I tried to
ping the gateway ip, but it did not succeed. Here are the details of
my network:

Configuration provided by the ISP:
IP - 125.99.103.150
Subnet Mask - 255.255.252.0
Gateway - 125.99.96.1

When I connect the modem directly to my laptop and fill in these
settings into the Windows LAN Connection Properties, it throws me a
warning that the gateway is on a different subnet. However it accepts
it and my internet works fine.

Now I connect the modem to the wireless router and try configuring the
same into the Static IP details of the router, it does not accept the
gateway ip at all. However it got solved with your suggestion to
change the subnet mask. But I am still not able to connect to the
internet. As mentioned before, I tried to ping the gateway, but the
request timed out.

I am completely lost one his one. If Windows can accept and work fine,
whats the problem with the router.

Do let me know if there's any way you can help me, I would be
extremely thankful to you.

Thanks again.

Regards,
Anand.

If that's what your ISP actually gave you, complain to the support
department! Because given those IP addresses, the Subnet Mask should be
at least 255.255.248.0 (For your reference, there's a handy calculator
at http://www.subnetmask.info/)

You need to be sure:
1. You're entering the settings properly in the router, using a correct
subnet mask.
2. Your laptop is getting the correct settings from the router,
including the router LAN port as the gateway address.

With your laptop connected to your router, open a command window and run
"IPCONFIG /ALL". Copy the output, and post the _exact_ result here.

The problem is with your ISP. The router is just less forgiving than
Windows.

You should also try connecting the laptop to the router with cable, ie
removing wireless from the picture, to check its not an issue with
that part.

Please be more careful with snipping and attribution -- I wasn't

Hey John,

My router settings are also the same as you had suggested. I have kept
the subnet mask as 255.255.248.0 and it connects to the rotuer.

I feel there's something wrong with my router configuration. Do you
see any problems here? Do let me know.

Thanks for all your time.

Regards,
Anand.

I am able to connect to the router intrface, so I don't think thats
the problem. Howver I have misplaced the LAN cable for the router, so
it will be sometime before I can connect it directly to the Router .

Do you see any other issue here ?

Can you use the router when connected by Ethernet cable to the router
(as Mark suggested)? If so, please post the IPCONFIG for that as well.

Does the router show a working connection to the Internet on its status
screen?

Mark is right -- it could nonetheless provide insight on your wireless
problem.

>Howver I have misplaced the LAN cable for the router, so
>it will be sometime before I can connect it directly to the Router .


Beg, borrow, or buy a cable.

>Do you see any other issue here ?


Hard to say.
