Greetings to the forum.
We recently set up a router (TP-LINK TL-WR841ND) here at home to be able to have wireless internet for a laptop we just bought, while keeping wired internet for the old desktop. This laptop runs Windows 7 Home Premium SP1 and the wireless connection has since worked fine on it, as so does the wired one on the XP SP3 desktop. Another laptop, also running Windows 7 Home Premium SP1, has often used wireless internet here too, and there was never no trouble whatsoever connecting it either.
As my little cousin now brought her laptop here and tried also to connect wirelessly, however, things didn't work so well.
Her laptop, unlike the other two which always connected ok, runs Windows Vista Home Premium SP2. I first thought that to be a curious coincidence, as the other day I had tried to connect another laptop running Windows Vista Home Premium SP2 too, and it then failed as well. I didn't take much care of that, then, though, as it was just a casual try anyway and I was on the run, so I just used the wired connection instead for the purpose on that occasion. But as now the failure repeated with cousin's laptop, and I wanted to try to make things hopefully work for her, as certainly it'll turn out useful other times, even eventually in networks other than this one here at home, so I digged a bit on the matter. And came to realize it wasn't all that much of a coincidence only, after all, that both Vista machines failed the wireless connection, as this appears to be one less than infrequent problem, from what I could read?
So, after trying some of whatever I could find suggested around to eventually resolve the issue and getting no joy in the end, I'm left wondering on the next step.
The problem is, as described in the topic subject, that I can't get this Vista laptop (Asus X50SL) to connect to the internet if using wireless with WPA security on. It always just states "Unidentified Network: Local Access Only". If either disabling security or using WEP, however, connection is successful and (apparently, at least) stable. I'm thus keeping WEP on for now, of course, though, as I was saying, I would like to hopefully have it work on WPA too, as it may come in handy if/when eventually connecting the laptop to any other networks too.
So far I've tried the following "fix" suggestions, all ending up in no result at all:
- In the router settings, changed WPA encryption to TKIP instead of AES.
- In the laptop's Network and Sharing Center, in the referred wireless network properties, set it to "Connect even when the network isn't broadcasting its name (SSID)".
- In the network adapter properties, disabled TCP/IPv6.
- Disabled "TCP/IP auto-tuning level" as suggested here
- Disabled "DHCP force broadcast flag" as described in this Microsoft KB article
- Enabled "DHCP broadcast flag toggle" as also described in that same Microsoft KB article
Note 1: Each of these "fixes", since not resolving the issue, I've reverted them back.
Note 2: Prior to have tried these "fixes", I had also already tried, even repeatedly, thought with no luck either, both "Diagnose and Repair" from within the Network and Sharing Center and resetting the IP stack as also suggested http://www.hanselman.com/blog/TheNuclearOptionResettingTheCrapOutOfYourNetworkAdaptersInVista.aspx'
>here, as so I had ran the Norton Removal Tool just in case, although I'm not sure whether this laptop ever had any Symantec product installed.
So, the next step I'd like to try is the obvious update of the network adapter driver. Yet, as said above, this is right where I'm left wondering on... (I reckon this should even perhaps have been the first step to have tried, yes, but then, as the laptop's owner is someone other than me
and updating drivers may sometimes deliver tricky results, so I thought I'd better "save it for last" as I didn't want to risk have things eventually going wrong right from the start...) The wireless network adapter in this laptop is Atheros AR5007EG. And, from what I could read, here
, it seems to be a rather "problematic" one?
(At once I could only wonder about the adapter in that other Vista laptop which also failed connection. How much of a tough coincidence would it be for it to be the same!? Must check, soon as having a chance...)
My doubt then is: what update "via" to go for, first?
Do it via Device Manager, choosing "Update driver"? And, in this case, should I previously choose "Uninstall driver", to first uninstall the current version?
Do it via Windows Update? There's an update for the network adapter driver standing-by in there. Release date is January 2009 whereas the current version of the driver is 220.127.116.11 dated from 07-05-2008. Unfortunately, though, when clicking the "More info" link (http://winqual.microsoft.com/support/?driverid=20239301
) in hope for further details or eventually a version number, no page ever gets loaded...
Do it via the laptop manufacturer's website? I've checked the Asus support website, and there's two "Wireless Lan Driver and Application for Vista" available in there: Azurewave_GE740_AE750_NE770_GE780 WLAN Driver and Application, version 18.104.22.168, dated from 23-10-2007 (i.e. older! than the current version on the laptop) and AW-NE771 WLAN Driver and Application, version 22.214.171.124, dated from 26-06-2008.
Or choose alternative websites which eventually provide more up-to-date versions of the driver? This, I say, as the Atheros website seems to be of no help at all for the purpose, as I've e-mailed them for support hoping that they might provide the latest version of the driver, yet they referred me to the laptop manufacturer's website. So I wonder whether to try the unofficial atheros.cz, which seems to be the most popular suggestion?... I read, in other threads in here, and in other forums, that the download from there worked for some, yet I wonder which version people refer to, as this detail is never specified, and atheros.cz actually provides several versions?... I'm however assuming it should be the most recent one available in there, 126.96.36.1998 dated from 30-04-2010, right?... It has also been referred a version from September 2010, from the HP support website, but atheros.cz doesn't provide any as recent, so I don't know, if there's any other "source website" I could try?... If I remember it right, think I also read somewhere about a version 7.9.x.x working too, for some?...
I truly, truly appreciate any additional guidance, for better deciding on this next step to take...
And thank you kindly, in advance, for the time and patience.
