I've just bought a new laptop where i have been using the wireless network to connect onto the internet. I have networked an old laptop and an old computer to a DSL Gateway. Both laptops have network cards and the computer is connected directly to the DSL. Recently when both laptop were being used the old laptop's internet stop working saying the page can not be displayed and said the wireless network is unavailable. The same time the new laptop was working perfectly though when I switched it of and restarted the new laptop it had the same problem.

Since then I have looked at both network cards on a friends laptop and they both work fine so they ain't the problem. I have tried deleting the network I had setted up and reinstalling it but the same problem is still arising. Both laptops also say Network connection unavailable

Does anyone have any ideas to a solution or what maybe the problem?

— the pattern you described (one machine working until the other is used or restarted) points more at the DSL gateway/router or its DHCP/service settings than at the wireless cards themselves. is on the right track: when the router’s address-assignment fails, clients often end up with a self-assigned address and report an "unidentified"/unavailable network, which is a strong sign the gateway is not handing out leases correctly.

Practical isolation steps: test only one client on the wireless at a time and try a wired connection from a laptop directly into the gateway to rule out the radio. Use the router’s administration page to inspect the DHCP lease table and the list of attached MAC addresses — look for duplicate entries, a very small DHCP pool, or many stale leases. Temporarily assign a manual IPv4 address (via the Windows network adapter properties) on one laptop in the same subnet and see if that restores access; if it does, DHCP is the culprit.

Router checks and fixes: check for client-isolation/guest-network features, MAC filtering, or incompatible encryption modes that could drop clients. Look for available firmware updates and consider increasing the DHCP lease pool or clearing the lease table. As a last resort, back up any ISP/PPPoE settings and restore the gateway to factory defaults — then reconfigure it carefully (this will wipe wireless SSID/password and ISP data).

Malware caution: worms can disrupt networks but don’t assume infection. If infection is suspected, isolate the suspect laptop, run up-to-date offline/boot-time malware scans, and check startup/autostart entries. If the gateway still behaves oddly after removing clients and testing with a known-good device, contact the ISP or swap the gateway temporarily to confirm whether the hardware itself is failing.

It might be a problem with the DHCP of the router, that it's not assigning ip's correctly.

Step 1) Try rebooting the router.
Step 2) Try to ping the router's ip, if successfull, try to ping 216.239.57.99 (that is google), if successfull, ping google.com
Step3) type the command  (Ipconfig/ all)  in to your commandline, check if you get ip
Step4) run Spybot or Adaware to clean out any possible spyware that could be killing your bandwith.

PS: Let me know if your network card is pulling an IP address, and if it starts with 169.254.
