We are having the same problem. We thought the problem was exclusive to wireless networking so we hooked up a cord from the D-Link router to the Vista computer, but that didn't help. My son's new desktop has Vista. It worked fine for a month or so, but within the last few weeks it's dropping our internet connection, not just for his computer, but for the other three that use the same wireless router. And when he's not on, the connection is perfect. We've been to every website and reset his Pv6 and his IP and his MAC and his pseudo tunnelling and you name it and we have reset it or disabled it and nothing helps. We are considering buying a new router but I've read that this problem is indiscriminate of all different types of routers/cables/connections. We really don't know what to do! HELP!!!!!!!!!!!!!!!!!!:crazy:
I would just like to say that I am having the exact same problme on my brand new Sony CR11Z laptop. Phoned tech support and they have NO knowledge of this issue; there is clearly something wrong with the drivers for Vista, and I hope that Intel or Microsoft get this sorted soon.
I am also surprised at Sony releasing a laptop without first realising this. Connection drops - or more specifically goes to "limited connectivity" and then can't find any other wireless networks! PLEASE if anyone has any knowledge of this and a possible fix, please do reply to this thread! I am at my wits end with a brand new laptop that I have to plug into the router with a wire.
OK guys, I've found a solution for all of you affected by this using an Intel network driver. Seems that a feature in this driver called "Throughput Enhancement" is to blame. I tried this on two machines of mine that were having the issue with an Airlink AR680W and they are both solid as a rock, no dropped pings; as well as the interweb is extremely responsive now. Please give this a shot and let me know if this fixesyou up.
I have about the same problem. I have bought a new Compaq C710ED (america : C714NR) and since the beginning i have the wireless drops. What happens exactly? (btw: it has a broadcom chip)
All works OK. In 3 seconds connection to wireless network. After a random amount of time (or data?) it just drops. When renewing the network-scanner Vista says it cannot find new networks! Normally there are about 5 different networks from people around the area in it. When the connection drops, the blue light of the WLAN on the notebook is stable.<UL><LI>Disable/enable the networkadaptor has no use: i need to restart the laptop or do it some time in sleep-mode and come back</LI><LI>I tried another wireless router: it has the same problem</LI><LI>Disabled are powersaving options for the networkcards</LI><LI>Latest drivers are installed</LI><LI>Two other laptops in the house with wireless cards (even 1 of 10 years old!!) always work perfectly with no drops!</LI><LI>It shows totally no networks when it has dropped: i guess this must be some hardware/vistadriver thing.</LI><LI>When it drops, it is not disabled from the devices: it stays there the same, works correctly etc.</LI>[/list]
I wrote it in a support-letter to the repair man at Compaq. They have changed the motherboard. It came back and guess what: it still does not work...
So i decided to test new things before a new sending:<UL><LI>Installed XP and the broadcam XP drivers: the same problem. Also dropping after some time!</LI><LI>Tried to disable that IPV6 tunnel adaptor as written in this threath... no result</LI><LI>Static IP adres- no result</LI><LI>Change from WEP to WPA: no result</LI><LI>Disabling IPv6: no result</LI>[/list]
So, what do you guys think about this?
I have the feeling that WHEN it drops the connection, somehow the wireless adaptor is turned off or in a big sleep mode, while all settings in windows and led-indicators on the laptop show a fine working card. But they have already swapped the motherboard in the last repair..!
i'm having the same issue with the net droppin at random,i have a dell laptop 1521 with a 1390 dell wireless card running off a netgear wgt624v3 .any ideas i've read through this thread but want to see if theres anything for my laptop.i've tried the firmware,mtu change,power setting all the way to 100% etc.any ideas?
Please, we have to keep these posts going. This is the only website that has a continuous discussion going on regarding this issue. I bought my Toshiba in December - Intel 3945ABG and Vista 32. Same problems as everyone else. I have spent endless amount of hours researching - no answers. Have tried all the drivers I could possibly find - nothing. I am sitting 2 feet from my router and it drops the connection every few seconds or won't even recognize the network.
This is a disaster! This problem has been going on for at least two years - search it yourself - countless threads and posts dedicated to this card and vista.
I've emailed Intel, emailed Microsoft - nothing. Any suggestions on where to turn?
maybe we all should start calling intel everyday till they get this fixed this is the most annoying thing i've ever come across and with no fix this is nuts.i'm out of ideas cuz i've tried everything in this forum
Update: I downloaded driver 18.104.22.168 from Intel and updated the wireless card. I also downloaded the PROSet/Wireless Network Connection software (11/8/07) from the Intel website. Both are available under the downloads for the 3945ABG
I now have full bars shown everywhere in my house. This never happened before and I previously always had the worst signal reception when I was closest to my router. However, I am highly skeptical. Basically, my connection speed seems slower than ever, it takes 10x longer to download or play videos online (i.e. youtube) and the signal drops while performing seemingly basic tasks (mainly when clicking on links on varies websites) along when on youtube and other video sites.
Also, when I run the manual diagnostics program I get "passed" on all test results except the ping test says "failed". Does anyone know what this might mean? Perhaps I do not have my router properly set? Is there any other software I can download to perform tests? I would like to provide everyone here with as much information as possible.
The connection is definitely much better than previously reported so obviously the software and/or driver download did something. However, the continuous dropped connection is extremely frustrating especially when I supposedly have a full bar connection.
