An internet connection sharing problem!

For the last 6 months a laptop ( 2K) linked wirelessly (ad-hoc) to my PC (
ME), ICS has worked well thru a dial-up connection on the PC, this weekend
our ADSL connection finally went live (hurrah!!!) Now I can't get the
laptop to connect to the internet, Now have full wireless connection file
transfer etc but no Internet on the laptop.

I am using an adsl modem/router conected to the PC via an NIC, I went into
the home networking wizard and noticed the NIC wasn't shown, both the
wireless adapter and all the dial up were listed OK , So I couldn't point
the ICS at the NIC. (it was at this point I lost all internet and network
access with the dhcp problem sorted by a restore!!)

If I dial up (even while connected to broadband!) I the laptop will access
the internet OK.

having spent the last 3+ hours going in circles any thoughts? before the PC
goes out the window!!!

You don't need ICS any more, you need to tell the laptop to connect via
the LAN. Go to the properties for the wireless adaptor (Control Panel |
Network Settings), highlight Internet Protocol (TCP/IP), and set the
Default Gateway and Default DNS server to the IP address of your router
(mine is 192.168.1.1 but check yours).

you need to tell ICS to share the wired connection out via the
wireless, assuming the modem/router is wired only.

I don't use ICS much now but I suspect you need to go to the dialup
icon in Network Connections and turn off ICS on that, then go to the
wired ethernet and turn on ICS.

the other issue may be IP addressing, ipconfig /all from a cmd prompt
to see what's what. The wireless should be 192.168.0.1 as that's ICS
default, wired needs to be a different subnet to allow routing.

Thanks for both replies, I tried to point The laptop at the NIC on the PC,
that did not seem to get anywhere... Found the command and pointed ICS to
the NIC (I felt a prat at that point, missed that setting completely!) still
nothing, at that point I could ping the router from the laptop but still no
internet. Then while I was looking at some of the tcip settings on the PC
suddenly I had my home page on the laptop!! so not really sure what I had
done at that point (if anything)

But when I try and change pages it times-out, Messenger and Skyppe on the
Laptop log in but you can't really do anything with them, it takes ages for
a page to load, I even tried to send a file via Messenger (I have 2 accounts
one on each of the computers) and it sent it but very slowly, in fact it did
succeed, though the sending PC claimed it had failed.

The fact that last week it was working perfectly with dial up makes it more
frustrating
These computers are getting closer to the window!!

perhaps DHCP renewed the IP address.

so AIUI you now have connectivity but only just. Can you ping
www.bbc.co.uk from the problem machine ? or ping 212.58.224.55 if not
?

your symptoms can be seen when different MTU values are used on the
same network. If you can get to www.speedguide.net/analyzer.php from
each machine you may see this, or use DrTCP.exe to set all the MTUs on
relevant adapters to a "safe" value like 1430 with RWIN / Receive
window set to 14300.

It's just the difference between dial up and using a router, takes a
bit of getting used to.

You router is connected to the Internet and knows how to direct traffic
to/from the Internet so you just need to use its abilities.
The router will have its own IP address, mine is 192.168.1.1 but check
your documentation for yours.

Once you know that then any PC connected to your network just uses the
IP address of your router - provided you tell it to - as its default
gateway and DNS server. As set out in my earlier reply.

Both the PC's must use the same address range as the router, so if the
router is on 192.168.1.1 then set the first PC to 192.168.1.2 and the
second PC to 192.168.1.3. The slowness you may be caused by one PC
trying to use the same IP address as the router which is not allowed.

If you try to use ICS then Windows will re-set the IP addresses you
have chosen and always to 192.168.0.1 (from memory) so don't use ICS,
you don't need it with a router.

are you sure the OP isn't using a wired router then using ICS to
provide wireless connectivity to another machine via a wireless NIC.
That's what I thought he was up to.

an access point would be better, but that's not what he appears to
have.

So is mine 192.168.1.1 &.2

Have done that and didnt' seem to make any difference.

now that makes a lot of sense because when I do an IPconfig it gives me some
0.0.00. addresses

If I disable ICS I get nothing at all, the modem/router is connected via
the PCs' NIC it has a separate (usb) hardwire for the laptop, I didn't want
to use that, defeats the purpose!
I can access the routers home page from the laptop on both IP addresses so I
would have thought the Internet address would have been easy.........

yes ping with 32bytes of data 212.58.224.55 gives min 24ms and max 28ms
avg. 26ms

I will look at that when I get home.

He said "I am using an adsl modem/router conected to the PC via an
NIC" so I was assuming (dangerous) that he was getting his access that
way? Could be wrong :-)
