I’m writing this post hoping it’ll save someone the trouble I went through last night. After I’d installed my new Linksys E4200 router yesterday, all of my gadgets connected to it as expected, except one. My wife’s HP Compaq Presario C700 laptop would connect, it accepted the WPA2 passphrase, but connectivity would be limited to “local only”. I assumed it was having trouble connecting to the new wireless-n network, so I tried to see if there was a driver update for the Compaq’s Atheros network card. And thus, I entered the incomprehensible maze called hp.com…
You’d think that finding the latest driver would be as easy as finding your computer’s product page, clicking “support”, and then there’s usually a section called “driver downloads”. And in fact there was. Except that it listed a completely different network card, from another brand. Not helpful. And neither was Windows Update, which didn’t list an updated driver as being available.
So, thinking by now that the driver wasn’t the issue, I returned to Google, and started searching for Atheros/Linksys issues. Apparently, there’s a known issue, and after a good half hour of puzzling together the best possible search string I found a page… on HP’s support forum! There was an new driver after all, and it indeed fixed the problem. That page in turn led me to a download page I’d previously been unable to find, with the driver update I’d been looking for.
So, if your HP (or Compaq) notebook has an AR5007 wifi card, connects to wifi, but goes into “local only” mode, try the driver HP offers here: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-82549-1&cc=us&lc=en&dlc=en. It fixed things for me.
