Toshiba Satellite Wifi Problem (atheros)

February 15, 2011 at 19:58:56
Specs: Windows 7
My Toshiba Satellite (C655-S5049) with Atheros wireless works just fine at my home and a number of public wireless locations (Panara Bread, libraries, school, etc.) There are many other public wireless locations where I try to connect and just get an "unable to connect" dialog box which gives me the options to "diagnose connection problem" (blames the access point), or to "get help" which pretty much tells me that help isn't available because I'm not connected to the internet.

The places that work, work consistently. The places that don't work, I've never been able to get in even though people around me are online with their machines.

I'm running thie machine pretty much as it was delivered out of the box. I've installed AVG for virus protection, and I have all the default protection settings (firewall, sharing, etc.).

Any help is appreciated!

Perhaps the wireless connection you have at home are unsecured and require no wep key or wpa/wpa2 phrase to be entered for security. Therefore you are able to access any unsecured wireless network, the network you cannot access probably needs a wep key or pass phrase to get in. I advise you read up on wireless security and secure your home set up. Many places called wireless "hot spots" offer free unsecured access, while others allow access by telling you the wep key or wpa/w passphrase. If the network is secured as most are you cannot gain access without security keys.

I appreciate your suggestion, but while my home wifi is WEP with MAC filtering, I've also been connecting at the city library, Panera bread, and 2 other restaurants without a problem (they have no encryption). Then there are the places I can't connect to like the downtown free wifi (Manchester, NH) and a couple of other restaurants. I've checked with other patrons who all told me there was no security - I even checked with the network admin at one place who assured me there was no security.

It's as though some of them have a setting that my Atheros chipset won't talk with...

Still hoping for an answer

Try to diagnose your problem and connect using specialized tool, i was using Maxidix Wifi Suite (, it's free trial so you will have enough time to try. Check the following: connection signal characteristics (actually used network channel, used cipher and auth. algorithms) check that your network profiles created correctly (export profile to xml and check security parameters), try to connect to network using this app, it uses another algorithm. Good luck!
