View 4 Replies View RelatedI have a Dell Inspiron 1300 which crashed, service tag . I was able to start it again using the Dell Operating System Reinstallation CD for XP Professional with SP1, that came with another computer. I then installed a Windows XP Professional Service Pack 3 and Internet Explorer 8. However the wifi (wireless) does not work. I went to setup and assured that it is enabled. I assume that I have lost the driver for it. Before the crash it had a working wireless connection. I need to know what driver to install to make it operate. Setup indicates that my computer has a MiniPCI card 1370 Broadcom Corp.

When I go to Network and Sharing Center it shows a drawing of my PC and then a green line to "Identifying" and a line with an X to Internet. It also says my access is local only.
View 3 Replies View RelatedI have a Dell Inspiron E1505 laptop that is about 6 years old running Windows XP. I have a Dell desktop with a cable modem and Linksys wireless router connected to the desktop to run my home wireless network.
Yesterday the wireless no longer worked on my laptop. I have a small wireless icon (looks like a computer monitor) with a yellow triangle with an explanation point inside. The messages are 'Signal Strength: Excellent' and 'Status: Limited or No Connectivity'. I have tried the following with no success:
- Rebooting the laptop (multiple timess)
- Resetting both the cable modem and router
- Turning off the desktop, resetting both the cable modem and router, and rebooting the desktop
- Took my laptop to work where a wireless connection is available and received the same messages
Thinking my wireless adapter / wireless card is bad I purchased a Linksys wireless USB adapter and just installed it. However it also cannot connect to my wireless network and issues a 'Open network Failure' error.
The Internet works fine from my desktop but is directly connected to the modem. I have not tried connecting the modem directly to my laptop to see if it would pick up the connection.
A month ago my ISP was routing half my subnet (129-254) over DSL. I just moved and routing no longer works without NAT. The issue is probably with the new DSL 'modem,' a zhone 1611-A1, but I am not sure how it should be configured.The 1611 is connected to a WRT610N, which works in NAT mode with the following settings:[code] With the previous settings, networking doesn't work from a workstation, though I can traceroute from the 610. I would like all workstations on the "LAN" to have fully addressable internet addresses like the previous configuration.There is an admin interface on the 1611, but the cursory settings I've tried don't work and I'm not a routing expert. The ISP is kindly routing my network, but they don't provide much support.

After restart I now have a red 'X' through the Tray Connection Icon and no networking (LAN & Internet).
The Status of the Network Adapter is 'Working Properly'.
System Restore rolls back okay to before updates but as soon as Windows Update runs we have the same problem.
I've re booted into Ubuntu and the Network Adapter works fine.
I'm using a dell Inspiron 1545 with windows vista home premium x64 bit. I recently had to reinstall the operating system due to some severe problems, and ever since, when I try to connect to a network it says "windows could not find any networks", so I hit diagnose, and it said that no wireless networking hardware is installed and configured on my computer.
View 11 Replies View RelatedWe have recently switched routers and now my laptop doesn't work wirelessly; it connects to the router but there isn't an internet connection. The laptop works fine when the LAN cable is plugged in though. Our other laptop can connect to the internet with or without the LAN cable. Both are Toshibas running on Windows Vista.I have tried various approaches such as downloading the latest Atheros AR5007EG drivers but it said that they're already the most up to date. [code]

View 1 Replies View RelatedInternet doesn't work on my laptop. after getting some worms that prevented me to open any programs, i did a recover from previous back up. but since then my internet doesn't work (with or without cable). wirelessly: my laptop says im connected to the router, but it says that i have no connection to internet. sometimes it says that i m connected to internet but even so when i try to open my browsers (ieplorer or firefox), it just says "unable to connect"With wire: when i trie to connect via a cable directly to the modem, it does the same thing, it says iam connected to the modem but i have limited access, and the browsers say that it can't open internet.i am using windows 7, have a dell computer and a belkin N1 wireless router, and using cable.i tried to restore the winsock using the netsh command, i used winsockxpfix, i used lspfix, i deleted my norton virus program, i reset my router to default, i deleted my cache-cookie-history from the browser, i think my driver are up to date, i check my manager device (they all work), nothing worked.
when i type the command ipconfig, it gives me:
ipv4 adress: 192.168.2.2
subnet mask: 255.255.255.0
default gateway: 192.168.2.1
when i type the "ping yahoo.com" i get:
4 received, 4 sent, 0 lost
my computer works fine and i can go online. i use wire for my computer and try the same wire to my laptop but not working. i tries another cable throught the router but still nothing.
I recently re-installed Windows 7 Ultimate x64 on my DELL INSPIRON 1546 and everything seems to work fine, except the wi-fi. It won't search for any wireless devices (including the router I have at home), showing "Not connected. No connections available". The wi-fi hotkey is not working.
When checking the Device Manager, it shows me that no Network Controller driver was found. As I could not get the driver online, I downloaded it from Dell website via my friends PC and got it into my PC via USB stick. Here comes the most interesting part...
When I try to install the driver, it says that it is not compatible with my system.
I just switched houses, and when I connected my computer, modem and router I found out that I have internet on my PC which is wired, but when I try to get connected with my Laptop using the wireless funtion, it doesn't work. The laptop finds the router and gets "connected" but when I try to open a web page, it says there's an issue with my internet connection, and also something about not finding the DNS...whatever that means...as you can see..

It says there's a "timeout" issue when I try to connect with WPA enabled.No one else is having issues connecting with their laptops and smartphones, so it must be a problem with my computer. [code]

I was able to start it again using the Dell Operating System Reinstallation CD for XP Professional but the wifi (wireless) does not work. Before the crash it had a working wireless connection. It appears that I need to reinstall a driver for it. How can I get a driver when I have no internet connection on that computer? I have tried loading on a flash driver from another computer, but it doesn't seem to transfer. What driver do I need and how can I get it to install on her computer?
View 5 Replies View RelatedI got an inspiron 700m laptop as a hammydown from my sister. It had all sorts of problems, so I had to order a new copy of windows XP and install that. I've been trying to connect to the wireless network at my college, but the instructions they give say to go to network connections and start by clicking the "wireless connection" icon. There is no such icon. I've tried all sorts of different drivers from dell for this model and none of them seem to do the trick. I know i have a wireless card becuase I've opened a little panel on hte bottom of the computer and seen it myself.

View 2 Replies View RelatedI recently upgraded to Windows 8 with my XPS 16. I know the Intel R 5150 is not working right with Windows 8 just like everyone else I've seen post on various sites when they upgraded. My concern is.. when is there gonna be an updated driver!? You would think if Windows was gonna make it available to upgrade your OS to 8 that they would have all this straitened out. Now I have to get rid of 8 just so I can have WiFi!

View 2 Replies View RelatedI have an Inspiron 570 desktop that has worked fine for at least 6 months since the warranty expired...we had a power surge last week while I was gone and when I returned I was unable to get the wired network to work. I ran the diagnostics and it said that my cable was not plugged in...it was. I rebooted, reseated cables, etc. with no luck. I reset the cable modem and router, reseated cables, rebooted, etc with no luck. I plugged the cable into a laptop and it worked fine.
The diagnostics tools on the desktop indicate there are no issues with the network adapter and that it is allegedly working fine. What I have noticed is that the light indicators on the RJ45 jack on the back are steady state yellow and orange, regardless of whether there is a cable plugged into it.
Dell 8400 - Vista - TWO 1GB 4200/&NBST 533MHz and TWO 512 5300 667MHz
If I install one matched pair, the wireless network is found and will connect to the network. If I install all four, the network is not found and the wireless will not connect. The network card is Netgear G PCI adapter 54MBTS 2.4GHz.
So I dug my old Latitude D630 out from the attic, turned it on, and it still works, and it actually connected to my router! However, only the wireless connects, not the wired connection. When I plug an ethernet cable in, the computer does not recognize the cable, and tells me a cable is unplugged...which of course it isn't.

"This computer does not have a wireless network adapter installed and configured" and it gives me the option to "Install wireless networking hardware, and verify that the correct drivers are loaded" . Where can I get this wireless networking hardware?, is it on a disk that came with the laptop or do I have to download it using another computer and manually install it on my laptop. I have already don't some research online and have download some drivers but can't seem to install them on my laptop.
