Network Hi, We have a network at home that has been running without problems for over a year. 2 pc's and a laptop on it. We today have added a second laptop to the network, everything is connecting fine. But we cannot get internet connection through the second laptop.

Try searching for drivers on the second laptop. also, try updating the firmware of all your networking equipment. those things alone might solve your problem.

I DON'T THINK YOU CAN RUN 2 ROUTERS ON THE SAME NETWORK UNLESS ONE IS USED AS AN ACCESS POINT.
1. Connect as local device or bridge - If connecting the second router via Ethernet cable, plug it into one of the LAN ports on the first router. If connecting the second router wirelessly, ensure the second router is set for client mode. Note that some home wireless routers do not support client mode; these must be connected by cable. Check your router documentation for details on its client mode configuration support.

2. Check / change IP address - Most home network routers use a default IP address setting. Often, these default IP addresses will not work in a two router environment. Check the second router's IP address value and reset it if necessary to work within the valid address range of the first router (and to not conflict with any other device on the network).

3. Disable DHCP - To avoid IP address conflicts between all of the devices on the home network, only one of your two routers should assign addresses via DHCP. All mainstream routers provide an option to disable DHCP as part of the router's configuration screens.

Instead of adding a second wired router to an existing network, consider adding a network switch instead. A switch accomplishes the same goal of extending the size of a network, but it does not require any IP address or DHCP configuration, greatly simplifying configuration.

zSB(3,3) Installing a Two Router Network Installing a router to work as the second one on a home network requires special configuration. Do the following on the second router to ensure it (and the devices attached) function properly:

1. Connect as local device or bridge - If connecting the second router via Ethernet cable, plug it into one of the LAN ports on the first router. If connecting the second router wirelessly, ensure the second router is set for client mode. Note that some home wireless routers do not support client mode; these must be connected by cable.

Hi whioch computer has a problem ?
A PC with the new hard drive ?
Mkae sure that you have the wireless adapter working on the computer.
If it is working then try to find the network .
Click Here for more info about wireless network.

This is just a problem with the wireless settings of the router, you can try first to reset the router by pressing the reset button for 20 seconds while power is ON and then after that you should be able to find the default wireless name of the router which is linksys, after you reset the router just need to reconfigure it back...

Well first make sure that the wirless card is enabled under the network conecsions wich is under the start button. If it protected by a WEP password make sure it is the corect one. Also you might need to adjust the properties on the adapter.

Here is an article that should help Ad-hoc networking access point

Most wireless networks are setup as infrastructure networks, meaning all communication is to/from a wireless access point/router that serves the same function as a switch/hub in a wired network as a central point to transfer communications from machine to machine. One works over the air the other through a wire.

There is an alternate form of wireless networking refered to as ad hoc -- in this version of wireless networking every wireless adapter can "talk" to any other wireless adapter configured with the same SSID (name) and security encryption (none, WEP, WPA). This is how somewhat less impromptu wireless networks are created similar to impromptu infrared networks some of us have used. One limitation of the ad hoc networks I have seen configured to date is access to the internet. I have posted an article where a stationary PC (required to be running for any other wireless machine to access the internet) with a wireless card in ad hoc mode could act as the router for wireless network but it required a cabled connection the internet. I suppose it could be a second wireless connection on a separate channel with a second wireless adapter in an infrastructure network but why? These types of networks are only recommended in another article for a limited (small) number of machines.

Based on this are you asking to create an ad hoc network to connect 2 PC's wirelessly without a wireless router or access to the internet from the wireless network (without a dedicated machine)?

Connect the home wireless network router box to the main PC through an ethernet cable with the PC powered off and the home wireless router powered off, then power on the PC & the router. Vista should locate the new wireless network and follow the windows vista network setup procedures. After the wireless network has been detected you then while the second PC's power is shut off you connect dongle adapter to the PC power on and XP will locate the new adapter. You will probably have to enter your networks pin for the connection.
