Lenovo T420 With Windows 7 - Can't Connect To Wifi Anymore
Oct 27, 2012
Today my laptop (Lenovo T420 with Win 7) started acting up and I can't connect to any wireless networks anymore. I remember having the same problem just after buying the computer, but then it just disappeared and I never found out what happened. I tried restarting, turning the wifi switch off/on and also enabling/disabling the adapter, but nothing worked. Then I tried switching the wifi card with another identical one, but that didn't solve the issue either.

I got a new laptop l and it asked for the p number under the router. I gave the number and it changed my unsecured router to a secured one. Not how do I get the password and the security key.

I bought an ASUS P8Z77-V motherboard, an i5 3570K and a Corsair Vengeance 4GB card a month ago. I built it with a Radeon HD 5670 graphic card, CoolerMaster 500W, a Sony lightscribe DVDRW unit and an old HD 500GB. The PSUs fan stopped working 3 weeks ago and I didnt notice this. While playing games the computer shut down, and I quickly opened the case. The PSU was hot and I could smell burned plastic. A week after I randomly tried to start the computer and guess what!? IT WORKS! Then I realised that only the fan was broken. I took the PSU and fan appart and lubricated the fan. It spins like a charm but I think I lost a piece of it and now its loud as hell but it works. I thougt this story might have something to do with the issue.
THE ISSUE: My internet has been working like a charm untill a week ago. A week ago the LAN or wired connection stopped working. I had to disable LAN adapter in BIOS else it would try to connect forever and I couldnt disable it in Windows. I didnt bother to solve it since my motherboard has a Wireless adaptor, so I just connected wirelessly. Today the wireless stopped working. I figured out that I might have goten a virus? I formated the disk and reinstalled WIN7 x64. I install the drivers, and the wireless and LAN still dont work. I reinstall WIN7 once again. Still nothing. I remember that I have to set the IP adress myself. So I go to Wireless adptor - preferences - IPV4 - type the stuff in, and when trying to close the window it freezes. After closing it in task manager a message "An unexpected error has occured" appears. I have to close Explorer.exe too and then after 2 attempts I get to close the window and save normally, but still no connection.

So, I currently have a desktop and 3 laptops connected wireless to the router in my home, yet the GATEWAY laptop no longer connects wireless. I have to use the wire in order to connect to the internet and it's starting to become annoying. I had to restore the Gateway laptop back to Windows XP from Windows 7 due to a LARGE amount of issues with Windows 7. I'm in need of this laptop in order to complete my paper work.

My laptop (Lenovo g560) runs windows 7 Home ed. About 3 months ago my parents changed the wifi password and so my laptop was unable to connect to our home internet, and I never bothered to fix it. It's been 3 months and now when I need to connect, it won't. The network appears in the list of detected networks, i correctly typed in the new requirements of the SSID, and when i press 'connect' it instantly pops up with 'Windows was unable to connect to XXXXXXX'. The modem is from Netgear. I've tried switching the modem off and on, the wireless activation swith on my laptop off and on, the Fn+F5 for wireless and bluetooth off and on, reinstalled drivers etc.I know its not a problem with my modem as wifi works for other mobile devices (like my iphone, other laptops etc), and my laptop has no problem connecting to the uni wifi network. There only seems to be a problem with connecting my laptop to the home network. Perhaps i've tried fiddling around with the 'properties' of the network too much and I've accidentally changed some settings i was not supposed to? how to restore the wireless settings of this network 'back to default' or in the state it was when i was able to connect.

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.

I was connected to a wifi-spot for two weeks and it worked all fine. Since a few days ago the owner of the spot changed the password and since then I can't connect to my internet anymore. I'm 100% sure that I have the right password but still when I try to connect it shows a yellow triangle with a black "!" on top of it, saying "Limited or no internet connectivity"[CODE]

I have a laptop that I want to sell, therefore I went to somebody to see my laptop and wanted to connect to his wifi. After repeatedly entering the pass for the wifi ,the wifi was still not connecting.
1. My laptop will see his wifi but after entering the pass will not connect
2. The pass is correct because I introduced the same pass on my mobile and I was able to connect to his wifi through my mobile
3 My laptop wifi is working fine because when I went home it connects automatically on my home wifi
4. I tried to open and close his router but I faced same problem.

The wireless Internet at home is not working on my laptop anymore. It's working fine on my mobile as well as with other wireless networks at school for example. No matter what browser I use I usually dont get to any website. Most of the time it says access: local only, or local and internet, or limited connectivity. If I'm lucky at the right time I can open a website but then it's gone again.

I bought new Lenovo IdeaCentre H430 pc and I'm having problem with high pings. Windows 7 with on-board realtek NIC. Fresh install, fully updated, drivers installed from included CD. When I start pinging router (direct 1Gb ethernet connection, 1 hop), pings start at <1ms (which is fine) and after a while they jump to 300-1000ms.
I loaded up live ubuntu to test if the problem might be in HW. It's not, in ubuntu pings were always <1ms.I also noticed that when I start using connection somehow, pings go down to 1ms, but go back up when I stop using it (tested by accessing live camera feed on LAN).
Power Options set to max performance. I disabled Interrupt Moderation on the NIC, didn't work.I tested it in the safe mode with networking, same problem there.
It slows down our client-server based programs, what's causing it. All I could google up was that disabling Interrupt Moderation would work, it didn't though.Computer is giving high pings to router when idle and normal pings when network is under load, it slows down our software significantly.

I have a lenovo netbook that used to connect to the internet seamlessly wherever I went. Now it doesn't even see any other networks in range. I tried to repair the wireless network connection - it could not complete because it could not connect to the netork. Wireless Zero Configuration service is started. I restarted the service - no difference.

I've finally made the jump into Ubuntu and put it on my laptop. I have never used Linux before so it will be a bit of a learning curve although it does look quite user friendly.
I have already connected my Ubuntu laptop to my wireless router so I have internet. I would just like to be able to access files on my PC and vice versa similar to Windows Homegroup but I have no idea how.
PC = Windows 7 Ultimate - Laptop = Latest version of Ubuntu (I think it's 11?)
