I have a toshiba laptop with ample hardrive space and 1.5 gigs of ram......Celeron M 530 processor My toshiba model is A-135-s7403........My problem deals with connecting to the internet via a linksys wrt54g router.......I can hook in fine being hardwired, but cannot hook in, via an air based router.... The problem is it cannot find any networks....I called tech support at my isp and also at linksys, but they could not resolve the problem.

What would you suggest.....I have a 2nd laptop, that can hook in Perfectly both ways......which is also toshiba.

I wish to thank all who help me, IN ADVANCE, for their kindness in sharing their time..... best regards....alan

Quick, practical checklist to narrow this down to (1) driver/service, (2) hardware switch/card, or (3) router/settings. It follows ’s diagnostic line — answering a few of his questions will speed the process — and adds concrete steps to try in order.

  • Hardware & Windows basics to check first: toggle the laptop’s physical wireless switch and any Fn+key wireless toggle; look for a Toshiba wireless utility in the system tray (these sometimes override Windows). Open Device Manager → Network adapters and confirm a wireless adapter is present and shows no error. In Services (run services.msc) ensure the Windows wireless service is running (WLAN AutoConfig on Vista/7). Run ipconfig /all and, on Vista/7, netsh wlan show drivers to confirm the adapter is detected by the OS.
  • Driver and power settings: update or reinstall the adapter driver using the vendor/Toshiba driver package (avoid random driver sites). In Device Manager, on the adapter’s Power Management tab, uncheck any “allow the computer to turn off this device to save power” option.
  • Router and environment checks: temporarily enable SSID broadcast and set security to a simple mode briefly (then restore) to rule out hidden-SSID or incompatible encryption. Check for MAC filtering on the router and try a different channel or move the laptop nearer the AP to rule out range/interference.
  • Isolation steps if the above fail: boot a Linux live USB to see if the card can scan networks (this separates hardware from Windows issues). Try a known-good USB Wi‑Fi dongle — if it sees networks, the internal card or its antenna/connection is likely faulty. If the internal card is dead, replacing the mini-PCI card or using a USB adapter is the usual remedy.

Answering ’s OS/DHCP/encryption questions will help prioritize which of these steps to try first.

What OS are you running?
Do you have a password on the wireless?
How far away are you from the wireless?
Are you setting the laptop to automatically gain an IP address?
