Question about Network & Wireless Adapters

1 Answer

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?

    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.

Hi, Please make sure that you have turned on the wireless switch on your laptop because this is a message that usually appears if the wireless on the laptop is disabled.Also please update the wireless drivers for your laptop from the Toshiba website. Thank you for your time and best wishes for your effort.

I have a lot of disconnection, after i installed SP1, with my Realtek adapter wifi

You might need to reinstall your drivers.

You can find Realtek WiFi drivers on their WiFi Driver Page. Simply select the model that is installed in your computer, download, install the drivers and restart your computer.

If you continue having issues, you may have luck contacting Toshiba Support to notify them about your issue. They may be able to provide vendor-specific information about driver/hardware issues related to Service Pack 1.

The answer is yes however i think that if you are having problems connecting that you should make sure that the problem is not with your wirelessinternet first.

New os installed..

Erm, install adapter? I mean, seriously, go the website of the manufacturers that made your bluetooth adapter and search for vista compatible drivers for your blutooth adapter. Once you get a hold of it. install it. It shouldn;t be an issue once you have the proper driver. however, please do revert back to me if you face difficulties. Thank you.

Wireless network disconnection sometimes

The Toshiba Satellite A210 has a built in wireless adapter - at least all of the ones I did a quick check on the specs. If yours has a built in wireless why are you using an adapter??? Presuming you have a good reason - have you gone in and disabled the built in wireless? They could be conflicting. Second I would use Network Magic software to setup your home network. I struggled many hours and could not get everything to work the way I wanted - all problems with home network fixed in minutes with Network Magic. I do not work for them or anything but I will tell you it is the best software money I have ever spent - and I have been around since 10MB was a dream hard drive.
