Wireless :: Toshiba Satellite Pro Laptop Has Suddenly Stopped Detecting Network

Jun 24, 2011

My Toshiba Satellite Pro laptop has suddenly stopped detecting my wireless network. IT detects every other network in the area but mine. Other computers in the house have no problem detecting and connecting.Wireless is enabled, it happens no matter how close or far from the router. The network is set to broadcast the ssid, etc. I have not changed any settings on my laptop or router, this has suddenly started happening. Have updated drivers to no effect.Occasionally, the network pops up when I re-start the laptop. Rarely works and sometimes it will detect the network, then fail to connect, then the network can't be detected at all.

Wifi Suddenly Failed With Laptop But Still Working With Iphone?

Feb 22, 2013

I have a Netgear N300 wireless router. My laptop is Sonay Viao, running Windows 7.
This morning my internet was unreliable, and dropping every minute or so. Trying to trouble shoot, I switched the router off then on again. Now I have no wireless signal between my laptop and router. The router doesn't seem to be recognising the security password. I have not changed the password - this is still the original password for the router. Other devices are still talking wirelessly to the router.

Laptop Suddenly Says Connected With Limited Access To Wifi?

Nov 20, 2011

I use a laptop and recently the wifi has stopped working for me. I can still connect completely but it says with "limited access," which results in me being unable to access the internet at all. The rest of the computers in the house work fine on the wifi and I double-checked the securtiy settings (WAP2 and all that) and it seems fine. What can I do? Tethering to my phone allows me to get on the internet and the computer connects successfully, but no websites will load whatsoever.

Lenovo Laptop Suddenly Unable To Connect To Internet Via Wifi And Other?

Feb 28, 2013

This is what I am working with:

1. Laptop LENOVO Refurbished (2012)
O/S: Windows 7 home premium Version 6 (build 7601: Service pack 1) 64 bit
Processor: Intel i5 - 2450M, 2.50GHz, Intel 64 Family 6 Model 42 stepping 7
Hard Drive C: 380GB HDD Free: 421 GB
D: 28.9 Free: 28.9

[code]....

Modem: Videotron Arris Model: TM502G
Router: Netgear N900 Wireless Dual Band Gigabit Router WNDR4500

how to use a computer in the time before Windows, comfortable with using command prompt. Have fixed many issue over the years with old and crappy computers, through research. Not very familiar with wireless connections. Last week laptop started freezing on Windows load, going automatically to safe mode. If I restart the computer after loading in safe mode, Windows opens fine the second time. Have tried stopping all other programs from loading at start up. If I do a system restore, everything works fine for a few days, then starts freezing on Windows load again. When Window does load I get the application error: The application was unable to start correctly (0xc0150002) click ok to close. but can still log in to Windows. Also, When I plug my cell phone, via USB to computer it charges fine and can upload and download between the phone and laptop, however, if I connect a (USB) thumb drive I cannot open the folder, save to it or open from it. This is the issue I wish to fix first so I don't have to keep switching between my ancient and slow CPU and my Laptop trying to fix the above problem(s): Laptop recently stopped connecting to home WiFi (automatically or manually.) Ran troubleshooters, suggested I do a full power off the router and turn it back on. Did that still not connecting. Did a full power off of laptop and modem and router and restarted everything. Still doesn't work. Used manual Diagnostic tool and it fails the association test, suggests that I check the profile. I don't know much about wireless as I said, so I do not know what profile I need to check or where it is located.The laptop does connect sporadically to the internet at home, via WiFi, for a few minutes at a time on its own, according to the wireless network connections. During this time I see one of two messages in wireless network connections: Unidentified network or limited access. If I go into the network sharing centre it says I am connected to an unidentified public network and shows that this network is not connecting to the internet. If I use the manual diagnostic tool at this time it passes the association test but fails the ping test.

Distance from the router does not seem to make a difference.Often when it is disconnected I cannot even see my router in the list of available wireless network connections.I can connect wireless to the router from my phone and have had no problems even while the laptop is unable to connect and the old CPU I am currently on, which is a wired connection, has had no trouble either. Other things I tried:I've scanned for hardware changes in my network connections: none and tried updating my driver software: nothing to update all are enabled.

HP Compaq Nc6220 Laptop Not Detecting Wireless?

Nov 7, 2012

I have an HP Compaq nc6220 that I just got up and running after an extended stint as a paperweight.It had previously worked great in terms of connecting to the internet via wireless.Now nothing.It let's me go into Wireless Network Setup Wizard and offers to let me set up new networks, etc...But as far as I can tell, it isn't detecting any networks (though they are all around me and detected on other computers) and giving me the option to log in.There is no "Device Manager" option that I can find on this computer, which some forum posts have suggested to other people with similar problems.

Laptop Not Detecting Wireless Networks / WLAN Card Disabled

May 19, 2012

When I click on the Wireless Network Connection icon it says "Wireless network unavailable." There's also an error message that says "The Dell Wireless WLAN Card is disabled. Use the Dell Wireless WLAN Utility to enable it." When I right click on the wireless network icon it says "No wireless networks were found in range. Make sure the wireless switch on your computer is on. To see an updated list, click 'Refresh network list.'" I don't have a wireless switch. I have a wireless enable icon and it says Enabled. My wireless network is working because my phone sees it and two other networks in the neighborhood. I couldn't find the Dell Wireless WLAN Utility. I also tried my iPhone hotspot. Laptop did not detect it either.

Wifi Network - All Devices Suddenly On 192.168.2.xxx Instead Of 192.168

Dec 27, 2012

I have an ADSL connection through Canal Digitaal, which I believe uses the KPN network. My Zyxel 2601 modem/router is usually accessed at 192.168.1.254. The following devices are connected to it: two iphones, a Macbook Air, an Apple TV 3 and a Mac Pro.all devices except the Mac Pro. Looking closer I found in their respective settings that they connect to 192.168. 2.254. All have somehow been assigned IP addresses on the 192.168.2.xxx network. The Mac Pro remains on the 192.168.1.xxx network.Going to 192.168.2.254 launches a login page for a KPN router called Arcadyan ARV7519 which is on ANOTHER SSID than my wifi network. Nevertheless, all my devices say they are connected to my network SSID but with IP addresses in the 192.168.2.xxx range.Does it have to to with the channels used by the respective routers or is there some phishing or such going on? What can I do to ensure that my devices stay on my Zyxel network?Weirdly, the SSID of the Arcadyan router doesn't normally show up in my list of nearby networks. It only shows sometimes.Also - in case it is relevant - when I try to access 192.168.1.254 from my Mac Pro I am able to log in, meaning I reach the welcome page of my Zyxel router though it takes a very long time for it to load.
