I have verified that I am set to auto connect however my wireless does not do so upon start. I have to do so manually each time I use my computer. This is a new problem since installing the newest driver update because I could not connect at all or randomly. The update fixed the connection problem and I no longer have dropped connections and wifi connection back to normal. HOWEVER it has left my auto connect nonfunctional.

I regularly get this message (but not everytime) when I start up Windows Vista Home Premium 32-bit.
"Dell Wireless WLAN Card Wireless Network Controller stopped working and was closed.a problem caused the application to stop working correctly. Windows will notify you if a solution is available."
Then I get this following message:"Solution Found: Address a problem with your WLAN card.Your WLAN card has stopped working properly. This is a network adapter that allows your computer to connect to a wireless network. To find out if an updated version of your WLAN card is available, contact your device or computer manufacturer."The strange thing is even though I get this message I am still able to connect to the internet via a wireless network. So there is no problem as such it is just annoying to keep getting this message when Windows starts up.I have checked on the DELL Support website and I do have the most up-to-date driver already (Or I think I do).
The message refers to my:
Dell Inspiron 1520, Dell Wireless 1390 WLAN Mini-Card (with driver version 4.170.25.17)

Having the same problem with a Dell Inspiron Laptop using a belkin pcmcia wireless card. It was working, but has stopped doing so. I was missing some network adapters which I have reinstalled, and the hard wired connection is now working again, but wireless will not get past the acquiring network address phase. I tried the ipconfig /all and it shows my IP address as 0.0.0.0 and the same on the subnet mask. it says the autoconfig is enabled and dhcp is enabled. My HP laptop is connecting to the wireless network just fine.

I have a Dell Inspiron 6400 laptop running and with a Dell 1390 WLAN mini-card installed and a Broadcom 44/10x100 integrated controller.
Unfortunately I've never been able to get this laptop to function with my wireless Internet.
Everything's working out nicely, and the computer connects to the network smoothly. After 5-10 minutes of full and unproblematic Internet connection the computer crashes the wireless network i.e. the Inspiron and all other computeres connected to the network is disconnected and my wireless network no longer shows up on the list of available networks.
The network works perfectly with every other computer I've used with it.
I've installed the newest drivers for both the 1390 and the integrated controller from this site. And my Vista is of course also fully up to date.
I've also tried turning the antennae settings to "aux" - Alas, to no avail.

I just came upon an old inspiron 6400 and i'm trying to get the wireless internet on it.
i believe there's a "card" (maybe, Sierra wireless aircard 580) missing and that would be why i cannot connect. Here's what i got on a linux command linedoom@Zombimatic / $ sudo

I was networking via the Broadcom ethernet card this afternoon. This evening it will not connect to the internet. I checked the device manager and it says the device is operating properly. I then tried wireless to the FIOS router and I got limited connectivity.

My bluetooth 365 suddenly stopped working, (Inspiron 1564, windows 7 home premium). I have the latest driver (6.2.0.9603), and now, when i try to install it again it asks me to turn the BT on, although it is on (enabled in BIOS). When I check the device manager under bluetooth radios, it's called "Generic Bluetooth Adapter" and it's status is "This device cannot start (code 10)". The bluetooth icon doesn't appear in the task bar nor in control panel anymore.
The bluetooth services @ administrative tools are "started" and "automatic".
I had this problem twice before, fixed it using system restore and by installing "windows mobile device center". These solutions are not working now..

I recently bought a new Dell Inspiron 7600 pc running on windows 7 home premium and to enable access to our wireless internet I installed a Realtek 8185 wireless pci adaptor. It has worked fine (although not without the occasional blip) but recently it has stopped working. I could connect to our wireless network but connection came with a small exclamation mark on the wireless connection icon in the system tray. I tried reinstalling the most up to date drivers I could find on the realtek download website and this has removed the problem of the exclamation mark with the wireless connection claiming it now has internet access. However the internet is now so slow (vastly slower than before these problems began) I get timed out errors whenever I try to access any web pages. I have ruled out the router being an issue as my two housemates' computers are working just fine.

I've been trying to setup a wireless ad hoc network so I can connect to the internet using my iPod Touch. My wireless adapter is Intel(R) PRO/Wireless 3945ABG Network Connection running the most up-to-date driver.
- Set it so Windows configures my wireless network settings
- Created a wireless ad hoc in Wireless Network Connection Properties
- Changed it so that network access is given to ad hoc networks only
- For my LAN connection under Internet Connection Sharing, "Allow other network users to connect through this computer's internet connection" is ticked I am able to connect to the network that I setup but when I try to connect to the internet it fails.When I check the Wi-Fi Networks setting on my iPod Touch it gives this information:
IP Address: 169.254.1.158.228
Subnet Mask: 255.255.0.0
Router: (blank)
DNS: (blank)
Search Domains: (blank)
Client ID: (blank)
I checked and that IP isn't my IP?

I have a Dell Inspiron 6400 running Windows Vista with a Broadcom 440x10/100 Integrated Controller. I've had the computer for 5 years, and have always connected to the internet using wireless with no problem. Just moved to a new place, don't have a router yet, and now when I try to connect via the ethernet cable my internet is sooo slow, taking about a minute to load a page. My roommate's computer runs great using the ethernet.

I have an HP laptop running Windows XP almost five years old which contains an Intel Pro Wireless 3945ABG network device. It connects fine with my router WiFi running off DSL. I recently bought an iPhone 4 and set it up as a personal hotspot. I've been able to connect a friend's Macbook to it. But even though my HP laptop sees the iPhone network, when I try to connect to it I get "Unable to connect to this network. It may be out of range." I've downloaded the current update for the wireless device.

Since successfully restoring my laptop to factory settings I have been unable to connect using my Intel PRO/Wireless 3945ABG Network Connection.Initially it worked, but after a while it stopped. I have completed several system restores, and the wireless connection works for a few days. On the last occasion (after installing windows updates) I received the dreaded blue screen and have been unable to connect.I am not sure if it is related to installing new windows updates as prior to restoring to factory settings I had no issues with my wireless connection.I am able to connect using the ethernet cable and I am currently able to connect using Pluscom wireless usb adapter.I am using the fujitsu siemens amilo pi 2515 notebook.netgear dg834g router?

My laptop won't find an ip address and connect to the Internet right now I'm using my iPod. I know the Internet is working. I have a Dell inspiron 6400. Two days ago I had an Internet connection but I had to switch it so it would automatically find an ip address. I cAn get a connection at my moms house and it works just fine but any where else it can't find an ip adress. I've gone to start>run>cmd>ipconfic then I go type in that ip and it connects but won't let me connect on a browser or messenger.
My laptop won't find an ip address. I'm only 14 and I've tried everything I could think of. Two days ago it would connect to the Internet but wouldn't connect on a browser or messenger so I hadda change the tcp/ip to automatic then it worked but now with different wireless Internet it can't find an ip address

i have an Asus u56e that I recently bought a couple of moths ago. It has been a great computer until today when my wireless randomly disappeared for no reason. The wireless adapter has been disabled for no reason, and when I try to re-enable it, I can't seem to find it.

I am running a rather old Dell Inspiron 6400 on Vista. Recently Virgin installed their latest Hub / wireless router for me and since then i cannot make a wireless connection to the internet. Before that I use to be able to connect to my old router (Linksys Wireless-G 2.4Ghz) no problem! I can connect via the ethernet cable no problems. The WiFi is on and even when I disconnect the ethernet cable, the bottom right hand corner symbol says that I am connected but I cannot load the internet and keeps giving me this message:"The URL is not valid and cannot be loaded."The Virgin Media support team ran a check and told me that my wirless adaptor is out of date and needs updating so I went on Dell Support, downloaded and installed the follwoing drivers but still no joy!
1) Broadcom diagnostic utility 440x 10/100 utility controller
2)Broadcom driver 440x 10/100 utility controller
3)Dell Driver Wireless 1390 WLAN Minicard
I have also ran a wireless WLAN utility diagnostic check through the control panel. In the Connection diagnostics, the Gateway IP Ping 'failed' and I think as result of that the Internet IP Ping, DNS IP ping and internet website domain name ping all 'skipped' but all else passed.

i just reinstalled windows on my laptop and i figured i could just download drivers from the dell website. after following the installation order specified on the website.. installing first the NSS and then the chipset, etc.. I realized there wasn't a driver for the NIC on the website. i also noticed that the steps didn't include a step for ethernet drivers, so i replaced the NIC step with installing the broadcom integrated controller. unfortunately, after completing the rest of the installation steps, my Network Controller driver is still not installed (looking in the device manager), a hardwire connection through the ethernet cable gives me "limited or no connectivity" and there is no wireless capability whatsoever.

After trying to communicate between an XP machine and Win7 using static IP and a crossover cable my wireless card stopped working. I did make the mistake of trying Homegroups prior to that.
It says Unidentified network and constantly remains in the Public Profile. Not even WiFi Sync is working...diagnostics reveal a problem with the drivers though several have been tried. From the originals to the latest version...Properties describe the device is working normally?

Just purchased refurbished Inspiron 15 Intel N5050. I know about Function-F2 and the wireless switch is on, but I can't get any wireless to work. I have tried to download drivers but they can't find the wireless card either. However, when I put the service tag in, it says I have the wireless card. The service tag is <ADMIN NOTE: Service tag removed per privacy policy>.
When I go to Device Manager, other "other devices," Network Controller shows up as not having a driver installed. However, the network adapter shows up just fine.

My friend has a dell d600 with the built in intel wireless card. All of a sudden his computer no longer shows that there is a wireless interface in the computer and he needs this computer for work. I'm thinking the driver may need to be reinstalled but I'm not entirely sure if it's that or a hardware error that's causing this malfunction.

The wireless on my laptop keeps dropping out. When I first got it it was fine, but after a while I started experiencing problems on every wireless network I connected to. Most of the time it would connect, but after around 10 minutes or so, the connection would drop out and the wireless card has to be "reset" so I can connect again. Otherwise I have a little yellow triangle over my network signal strength bars. I've updated to the latest drivers (14.2.0.10) but it was no luck.
This happens with every wireless network and I know it's not the network because my old Vostro 1500 is running just dandy on all of them.

I wiped out a Dell Inspiron 2200 and re-installed Windows XP Pro SP3 on it. Everything seemed to work fine until I try re-installing the Wireless Driver. The dell support website pointed me to the Intel PorSet/Wireless 11.1.0.30, which I downloaded and installed successfully, with the only problem.... It does not work.When I open the utility it pops a message saying that the "Driver is not installed", and no signals show or anything. When I go to the device manager, the OTHER DEVICES shows a "network controller" with the yellow question mark, but when I connect to the internet (via ethernet cable) to update the driver, windows can't find nothing out there to solve the issue.

I have just got my new xps 17 and opted for the 6230, It only gets to 20 meg download speed, I can insert my old usb N adaptor and get the full 50 meg. I was on the phone for 2 hours last night with Dell, they had remote access and tried lots of things to improve the problem.
Finally once they saw that my old usb adaptor was much faster, they said a technician would call me back today betweek 12pm and 1pm or 4.30pm.

I have a toshiba satellite laptop (windows 7) with wireless on-board and an ethernet cable port. Up until last night, both worked flawlessly since I bought the computer a few years ago.
Now, the wireless still works in three different locations I have tried (i.e. three different networks), but the ethernet cable will not work. I thought it was the ethernet connection on the mobo at first, but then after acquiring a USB-NIC connection, I found I had the exact same problem... I can't connect to my router or even direct to the DSL modem using a ethernet cable. I know my system is good since all my other computers (7) work with wired connections, and my laptop doesn't work on other cables on which other computers do. Essentially, it appears that my computer has lost the ability to get an i.p. address using an ethernet cable of any kind. Both the onboard card and the usb-nic cable tell me they are 'working correctly' in the systems/devices/network adapters section. I have tried disabling one while trying the other. I have tried disabling the wireless while trying either, and still nothing.

I share my internet with other gadgets via an ad hoc WiFi network via my laptop running Windows 7 Home premium. The range covered is extremely bad. At as less as 10 meters away, in an open hall, from the laptop sitting on my home office desk the signal is weak - it shifts between zero and one "curve" on network notification icon on my gadgets.The signal is non existent in the floor immediately below. (The floor is made of reinforced concrete.)
