Windows Vista and Wifi Problems

More information on Windows Vista.
Have you encountered Wifi problems with your Windows Vista?
I was connected in the internet through Wifi when I transferred location, unfortunately I lost signal which probably means I am out of the Wifi range. To get signal again, I went back to Wifi range but unfortunately Windows Vista could not detect any wifi network in the area. I turned the wifi on and off but to no avail. Last resort, I restarted Windows Vista and the wifi network was located.
That was a real pain considering all the opened applications I have.
More information on Windows Vista.
i have an acer aspire series 4715. it has an xp and vista os. the vista can detect the wireless connections available, but i cannot browse the internet using either ie or firefox. in the xp, that little icon thingy on the bar which indicates presence of wi fi connection does not even exist.
caused by 2 settings
DhcpConnDisableBcastFlagToggle
DhcpConnForceBroadcastFlag
in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\
Start > run > regedit.exe
2. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
3. {GUID} sub-key refers to the network adapter that is having the issue.
4. Add a new DWORD (32bit) value and rename it to DhcpConnDisableBcastFlagToggle.
5. Modify the DhcpConnDisableBcastFlagToggle key and change the value to 1?.
6. Modify the DhcpConnForceBroadcastFlag key and change the value to 0?.
7. Reboot and test the connection again with DHCP.
I have read in a Windows Vista book that the closest WIFI router will demand the connection and force you connect to that access point. I have the same issue with losing all WIFI connections then having to reboot. If I log into the closest router, disconnect then try to log in into another access point, all of them will appear. Sometimes, the one that I want to log into won’t allow me to, which forces me to log into the closest WIFI router. Then I will be able to log into the access point that I want. This clearly is a Windows Vista issue.
My problem (also only with Vista), was that it would take 2 to 20 minutes before the internet was connected, though I had immeadiate good local connection. What seems to have improved this to 3 sec to max 3 min now is a de-selected setting ‘çonnect to a more preferred network if available’. This can be found in < Network and Internet > Network and Sharing Center > View status (from Wireless Network Connection)> Wireless Properties>.
I purchased an Acer Aspire 4530 last December 15, 2008 with the following specs:
a. Processor: Turion X2 Ultra ZM80 (2MB L2 Cache)
b. OS: Windows Vista SP1 32 bits
c. WLAN Card: Atheros AR5B91 (driver 7.6.1.162)
I connect thru our CISCO wireless access point which is connected to a PIX 501 firewall. The disconnection problem started when I installed the Windows Vista Updates. I tried the following to correct the problem but to no avail:
1. Disabled IPV6 (did not work)
2. Installed WLAN optimizer (did not work)
3. Used various netsh commands as I read from
forums (did not work)
4. Disabled Bit Defender Trial Version (did not work)
5. Disabled Windows firewall, Windows Defender
(also did not work)
As a last resort, I reinstalled Windows Vista SP1 from the DVD (did not connect to LAN to prevent getting Windows Updates). Without the Windows Vista updates, I installed the Atheros driver 7.6.1.162 and Odyssey Client for Vista. The network name is hidden so I had to “Manually set-up a network connection”. I selected the Unnamed Network (Security-enabled Network) and gave it our SSID name. Windows asked for more information so I supplied our networks’ username and password. Eureka! My wireless connection is working perfectly again!
Hope this helps.
I had the same problems for a while. I found out that “right clicking” on the wireless adapter and choosing properties. unselecting IPV6 fixes the “no connect” and “slow issues”. Vista seems to be trying to negotiate through IPV6, which at this point is not needed.
I’ve been having similar problems recently. I have vista, and while I am at home I have a HORRIBLE time trying to connect my laptop to the internet, meanwhile the desktop in the living room is working fine. Because the desktop is going great, I doubt the router itself is a fault, so I’m at a loss as to what the problem could be. When I’m at friends houses, my internet connects flawlessly, so is my house just a cursed? I don’t know what’s going on…
I am using acer laptop w/ windows xp while my older sis uses Sony vaio windows vista. I got disconnected on WiFi whenever she turns on her SONy vaio laptop. I got dc twice (when she turn on the pc and when she log in). After i dc twice, The connection returns normally. But can anyone help me about this? what should i do to not get dc on wifi when she turns on her sony vaio laptop? Pls help. thanks.
Thank you very much Rob.
Your solution seems to be working.
I’ve had trouble connecting through wi-fi for the last couple of days.
The laptop runing on XP is doing fine.
It all started when windows vista downloaded some updates for internet explorer.
Then more updates followed and wifi started to work again until the last pack of updates and we had to connect through the cable(what the point of having a wireless connection then?)
Disabling IPV6 seems to do the trick for now…
Umm… If vista’s so crappy, why not download Ubuntu? http://www.ubuntu.com/ – It’s quite a good replacement if you ask me, and any problems can *actually* be solved. But if you aren’t the person who will fix problems yourself, don’t download it. It’s not for n00bs.
The issue is with VISTA. This is established, looking at some of the post, some are of differing origin, but if you have a laptop that has internet at one time and then loses the connection and can’t find a wireless network, then here is what you need to do.
Microsoft hasn’t made a patch for said issue and even sending it in to them the charge will be around $115.00 and there won’t be a resolution and they will promptly refund your money. You need to go hard on the maker of the system (i.e. Gateway etc.)
Once you have leaned on them hard enough and jump through the hoops of updating the drivers and re-installing the factory settings and OS then they will set up a repair service and you just pay one way shipping in most cases. With Dell if you have a business contract they will send a tech out to repair it in the next business day.
Vista is just crap all round, my wifi always cuts out when using vista, but I’ve been using ubuntu for ages and not had a single problem with the wifi on my laptop.
I agree VISTA is without a doubt the problem. I have an XP laptop works fine, had an old XP desktop and it worked fine, I have a wifi radio that works fine, I have wifi on my mobile phone and it also works fine. I was even so foolish as to get a new wifi router but still the vista keeps dropping the connection.
I’m working on transfering to open source software because I do not have the time to continually deal with microsoft errors and watch as they ignore the problem.
What worked for me was to create a wireless profile for my router. This was created by going to “Control Panel\Network and Sharing Center” and then clicking on Manage Wireless Connections and clicking the Add button and then creating a profile suitable for my router.
I have the same problem, try this guide and tool, it might help.
