Problem with Home Networking

By vijay.d ·
I have a Toshiba notebook with XP Home installed & a desktop with XP Prof. installed. The desktop is connected to the net through a DSL connection and acts as a gateway for the laptop. The laptop connects to the the desktop through a hub.

This setup used to work fine till a few days back. Suddenly it stopped working, i didnt make any changes. Now i cannot connect to the net from the laptop, but i can see both the computers on the LAN and even share files. Net works fine from the desktop.

The IP address is assigned automatically in the laptop & the gateway is set as (which is the local ip address of the desktop). Please help me get net back on the laptop !!

First of all, I would recommend scratching that entire setup and starting over.

A better setup would be to purchase a router to replace the hub. With today's $30-$50 routers, you gain wireless capabilities, NAT, firewall, IP and MAC filtering, DHCP, etc.

And, of course, you're offloading all that functionality from the desktop to the router so you don't have to leave the desktop on all the time.

A) less processing for the desktop B) the embedded OS of the router (typically Linux) is alot more secure than the XP desktop C) a hardware router will always be more reliable and faster than software routing (XP ICS).

I've only touched on a few of the benefits, but getting a router, especially as cheap as they are today (I've seen the D-Link 524 as low as $29.99) will provide a better overall network for a home user.

Check for any type of firewall. If its a new laptop you probably have either norton/Mcafee. Temporarily disable them to see if that works. Make sure your laptop has none of its connections bridged it can cause problems at times. Go to cmd prompt and do a tcp\ip release and renew. Another solution would be to turn off your dsl modem, hub, and all computers for about 5-10 seconds.

INTERNET connection sharing on the desktop for the laptop, right? just suddenly stopped working?

This has happened to me, it is caused by an automatic windows update on the desktop... you might have to uninstall and reinstall and reconfigure INTERNET connection sharing on the desktop... or the easiest way... just get a router...

The most likely thing is that a MS Patch has stopped the Internet access.

The cheap way out of your current problem is to run the Network Setup Wizard on the gateway machine first telling it that it connects directly to the Internet and allow File & Printer sharing and then run the Network Setup Wizard on the NB telling it that it connects to the Internet through another computer or Residential gateway. Allow File & printer Sharing here as well.

While a router would be better if you don't constantly keep it up to date it will give you a sense of False Security so personally I wouldn't bother with one unless it is necessary for specific application.
