Hi guys,

Back again.

Having a complete mare with my internet now that I've got the PC working.

INFO
I've bought a LINKSYS wireless-g router and also a LINKSYS Speedboaoster so that my partner can be in the internet in his room and I can still access the internet from my laptop (which has a CISCO Systems card installed).

Initially, when I ran all the products together they worked fairly well. However, after realising that my Windows XP was not genuine I installed a new copy of both PC and laptop. Since this time only one person can connect to the internet at one time and it has to be through the LINKSYS Speedbooster.

Basically, I've loaded all the info onto the PC and created a secure connection to the internet. I've also copied down all the numbers/secureity codes onto the laptop (as I hoped that this would allow me to access the internet through my PC).

My laptop adaptor card is seeing the network, but it won't let me hop on.

I'm not hot on networking, so wondered if it was a networking problem. As a result, I then started running various networking wizards, none of which are doing the trick.

Can someone please help me as I dont want to have to log of and unplug the LINKSYS adaptor when I don't have too, also I've paid for a CISCO card, which doesn't seem to be working.

described a setup that used to work but stopped after reinstalling Windows: the main Linksys router, a Linksys “SpeedBooster” range/extender, and a Cisco wireless card on a laptop. The symptoms — laptop sees the SSID but won’t join, and only one machine can access the internet at a time (through the SpeedBooster) — point to a small set of common problems: DHCP/Internet Connection Sharing conflicts, extender mode misconfiguration, or a wireless driver/encryption mismatch on the Cisco card.

Begin with quick diagnostics from each machine to locate the failure point. On Windows run:

ipconfig /all
ping <router-IP>
ping 8.8.8.8
nslookup google.com

Verify that clients get a LAN IP from the router (not 169.254.x.x), and that the Default Gateway is the router. If clients cannot ping the router, the wireless link or extender pairing is the issue. If the router is reachable but internet fails, the router-to-modem link or ISP settings need attention.

Practical configuration rules to apply: make the Linksys router the single DHCP server; disable DHCP on the SpeedBooster and set it to Access Point/bridge (or proper repeater mode per its manual). If using wired backhaul from extender, use a LAN port, not the extender/WAN port. Check wireless security: older Cisco client drivers may not support newer WPA/WPA2 modes — update the card driver from Cisco and, for testing only, try temporarily removing encryption to confirm driver/compatibility issues. Also confirm ICS on the PC is off (Windows can accidentally be sharing one connection and acting as the gateway).

If settings are tangled, factory-reset both Linksys devices, update firmware, then reconfigure the router first (enable DHCP), add the extender in AP/bridge mode, and finally connect clients. Leave wireless security enabled once confirmed working. These steps address the most likely causes without changing ISP settings.
