WiFi unable to connect/maintain connection

Laptop: Toshiba Satellite L300-1BV OS: MS Vista Service Pack 1 Home Premium Wireless Adapter: Realtek RTL8187B Wireless 802.11b/g 54Mbps USB 2.0 Network Adapter
I have been able to connect wirelessly for short periods of time, and other laptops/mobile devices can connect fine. My new laptop (the above) occasionally can connect but otherwise lists my router but returns ''Cannot Connect''. All the settings are correct (I have tapped them in time and time again) and the laptop is right next to the router.
I have (what MS say are) the latest router drivers, but in the list of items the adapter uses there is a spelling mistake : ''Realtke RtlProt WLAN Protocol Driver''. I'd guess that this makes no difference - unless the actual protocol has mistakes in it too?
Thanks.

    Solution found...


    Updated Realtek driver (downloaded from Toshiba). Upgraded the router's firmware (Netgear Version 3). Netgear have an advice note that lower versions of their firmware wouldn't maintain connections with newer wireless cards (especially as our router is set not to broadcast it's SSID and only connect to certain MAC addresses with a WEP key - it left Vista looking a bit confused).


    Hope this helps anybody in the same boat.

Hello b... couple things.

First; see if going into Control PanelNetwork Connections and disabling the wireless network connection, then enabling it again fixes it. If it does then you have a work-around...

Second; there was a Realtek driver update offered by Windows Update. If that has
been installed (Control Panel-Programs and Features-View Installed Updates)
roll it back to the previous driver through Device manager and get the
update direct from either Toshiba or Realtek.

See if that helps.

This seems to be happening with that Wireless card and Vista... let me know what happens please.

Wireless association failed due unknown reason

There's always a reason but who cares if there is a good solution. Try rebooting your wifi router and then your PC and see if the connection returns. Also try to delete your WIFI network connection. Then reboot and it should return and so may your connection! If its a secure connection check if your password is correct by opening your WIFI network connection by double clicking it and clicking on wireless properties and then the security tab. Confirm your security key exists and is correct.

This is not a problem. Wireless connections sometimes tend to be inconsistent. Try closing the distance between your laptop and the wireless network adapter.

Toshiba Satellite A135-S4447 wireless adapter not useable in windows XP

Well of course I do have to tell ya that downgrading from the original operating system which is Vista OS on your computer will cause alot of issues, Usually you will need to go to each and every manufactors website for each product and locate the driver yourself because every Computer Manufactor company will tell you that you should keep the windows operating system that came with the computer or they will not provide you any drivers, and they mean it, I tried downgrading from Vista OS to XP and had no drivers ... I would try going to the Wi-Fi adapter/card manufactors website and try to locate a driver. That is your bests bet Toshiba is not going to help any...especially if warrant is out of date...Let me know how it goes!

Vista Premium wireless network callapse

Go into device manager, under control panel, go into network adapters, select your wireless adapter, right click on it, click uninstall, if you're with vista, it'll prompt you to delete the drivers, just leave that box unchecked then click ok. After the adapter is gone, click on action on device manager then click scan for hardware changes. The wifi adapter should be re installed. after you check that the wifi adapter is back on the list, you can exit device manager. Click start, connect to, try to reconnect to your router and it should work fine. After you have established internet connection and you can browse, you can download tthe Skype program again.

Hope this helps

Toshiba Satellite A205-S5804

Download the 8187b drivers from Realtek's site. You then need to go in and edit the .inf file to read like this:

;;****************************************************************************
;; IDs for 98SE/ME/2K/XP
;;****************************************************************************
[Realtek]
%RTL8187B.DeviceDesc% = RTL8187B.ndi, USB\VID_0BDA&PID_8197&REV_0200
%RTL8187B.DeviceDesc% = RTL8187B.ndi, USB\VID_0BDA&PID_8189&REV_0200

After the edit, install as usual from the device manager.
