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.

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.

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.

>whats the problem with the router.
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.

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 :).
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.

Beg, borrow, or buy a cable.

These two readouts are obviously going to be different. One is NAT'd
behind a rtr and the other is directly to the ISP's modem. These look
completely valid to me....almost anyway. The only issue I see is it may
be better, when ging thru the rtr, to have the PC DNS set to the rtr
IP...192.168.2.1
(Of course, I have seen rtr's that don't properly forward DNS.)
I take it you had the PC connected directly to the modem, and are now
just adding a rtr to do wireless over ?
Stupid question.......have you re-booted the modem itself when you switch
the attached device ? If a PC is connected to the modem, and you put a
rtr between the modem and PC, the modem must be power cycled with the new
device connected to it before it will pass internet traffic.
The procedure is....
1) Power everything down....modem, rtr, PC.
2) Turn on the modem.
3) AFTER the modem is sync'd up completely at the head end, then turn on
the rtr.
4) After that has fully booted, now turn on the PC.
If you do not power cycle the modem, it is still expecting the old device
to be connected to it with a certain MAC address.

Hey Dan,
It worked !!! Thanks a lot ! I followed the exact procedure and it
found the internet.
But now I am facing another problem. :((. The access is very slow.
Initially I thought it was the ISP problem, because I was not getting
good speed when connected directly to the modem as well. However later
the speed was better, but if I used my router, it was very slow. I
tried pinging a few sites from command prompt and found significant
packet loss. I am attaching the results below.

Not only very high packet loss, but also very high latency.
Run a traceroute (tracert in Windowspeak) to see where these problems
are occurring; e.g., "tracert -d google.com".

I wasn't sure if you had done that or not so I just threw out the
suggestion...you're welcome. I'm not sure if the necessary modem reboot
is listed in the (any) rtr's manual, then again....who reads the manual,
unless you're trying to find out how to 'reset to factory defaults' !! I
know I got bit with that one when I added my first rtr years ago.

Time to find that CAT5 cable to connect by wire to the rtr and retest
again to isolate where the problem may be. I assumed the numbers you
posted were for the wireless connection.
You can do ping tests again, but do tracert's also. For the ping tests
with 2 & 3 below, do you have another wired IP device on the rtr ? I
would test local destinations as well as internet destinations. If it an
interference issue on wireless, that should be affected for local pings
as well as pinging an internet host (this will help separate any possible
internet issues from possible local issues).
(As a note, if you add the /t switch to the ping command, it will ping
continuously until you stop it with a CTRL-C. Not particularly helpful,
but you can see if the results change over 30 seconds or a minute,
compared to a 5 second 4 ping test.)
Test-
1) PC to Modem directly
2) PC on wire to rtr
3) PC wireless to rtr
If 1 & 2 are OK, it's a wireless issue.
If 1 is OK and 2 & 3 are bad, a rtr issue.
If all 3 are bad....drop back 10 and punt !!!!!!! But seriously, test 1
should NEVER be bad. If it is, it's either ISP or some bizzare networking
issue with the PC.
Re: My Router does not accept a gateway ip that has a subnet address different from the laptop ip address
Hey Dan,
Guess what !! My roter works absolutely fine now. :)
All I did was get rid of Windows VISTA. I was all the while trying to
configure this thing on VISTA. It shouldn't have been a problem, but I
dunno why.
I am back to good old Windows XP now. Tried all the tests you had
suggested. All worked fine and the tracert results were better than
before. In fact I am am sitting at least 40 feet from the router and
typing this message. and downloading my mails without any issues.
Anyways I want to thank all you guys (John, Mark and of course Dan)
for the help and advice. Really appreciate the time and effort you put
in to answer the queries.
Thanks again.
Regards,
Anand.

Did you mention Vista before ?
If you would have, in addition to the rebooting procedure, I would have
also mentioned that Vista comes by default with IPv6 enabled, and from
what I have read in several of the Vista groups, turning off the IPv6
service (or however it is implemented) solved many networking issues.
