Unable To Detect Wifi Network On Laptop

May 18, 2011

I have an Asus 1001 PG netbook. I am having problems with my home wifi network. When I turn on my laptop, I do not receive the signal for our home wifi network. However, I know that the network is working because other laptops at home are able to detect it. I don't think there is anything wrong with the laptop because I can still detect other wifi networks in our neighborhood. The problem only seems to be with our home wifi network. If I restart the computer, the problem is usually solved. This is not an efficient solution for me as I am used to turning my laptop off on hibernate and I don't like having to reopen all my documents.

Laptop Cannot Detect Any Connections?

Jan 23, 2013

My ipod and my brothers ipod both detect and connect to our wireless network. Our PC connects to the network through a wired connection and is having no problems. I got a new laptop, have Windows 7 professional installed, and my computer will not detect any networks. I even tried unplugging the cable from the back of my PC and plugging it into my laptop, and it still does not detect a connection[CODE]

Asus RT-N10 / Unable To Detect The Wired Connections

Jan 31, 2012

I connected the router to the modem with an ethernet cable and the laptop to the router with another ethernet cable. A CD came with a router (Router: Asus RT-N10), so I put that into the laptop and followed the setup. The setup offered me to install something called Wireless Router Utilities, so I followed the setup and got to the point where it asked me to connect all cables etc. I did it already, but it kept telling me that the cables aren't connected. "Unable to detect the wired connections" I decided to skip that step and opened the browser, typed in the IP and got to the other setup thing. I typed in my ISP user/pass and I guess it sorta worked. I want to configure the router etc., to pass it and all. I go to the control panel, setup new connection, type the router PIN, I name the network, I put a passkey, and I click next.It says "Setting up [network name]" and after a minute it says "The network set up was unsuccessful". And that's it. No error notes, no nothing, just a button which allows me to retry.The OS is Windows 7 Home Basic. It's a new computer so almost nothing is installed. No anti-virus etc. Router: Asus RT-N10. Modem: Billion BiPAC 5200RC ADSL2.

HP Pavilion Dv6308nr - Laptop Cannot Detect Connections

Jan 22, 2011

I was using my laptop on a different wireless connection than I usually use and it was working fine, and then the internet stopped working and it told me there were no internet connections available. The two people on laptops that were beside me had no trouble using the internet, though.So I brought it back home to connect to my home network and it is still giving me the same error. I used the other laptop at home to connect to the internet, which it did with no problem, to write this.

I also feel I should note that I have an HP Pavilion dv6308nr, which has a physical wireless switch on the front. When you turn it off, the light next to it turns red, and when you turn it on, the light turns blue. No matter how much off and on switching I do, it will not turn blue. It will not "click" anymore like it's supposed to, which makes me think it's something wrong hardware-wise. But I don't know if this is related, because it may have to actually be connected to the internet for the light to go from red to blue.

Microsoft Windows Vista - Unable To Connect To Some Wifi Connections?

Oct 2, 2011

I have just moved homes and I am unable to connect wirelessly to the internet through the network in my new house. The computer is connected to the network with excellent signal strength but access shows as local only and will not connect to the internet.

All other computers have been able to connect to the internet with no problems, and my computer will connect to other wifi connections, no problem.I can connect with a wire directly to the router, but no luck with wifi. I have also had this problem with one previous wifi network. I have tried many things, including taking the compter to a computer shop for them to look at and having another professional look at it, but so far no luck.

Samsung UE32ES5500 - Bridge Two Connections In Windows 7?

Jul 3, 2012

I have recently bought an Samsung UE32ES5500 and I want to connect it to the internet. Not wanting to buy an expensive Samsung wireless adapter for the TV, I've decided to use an ethernet cable. Because the Internet cable passes through underground to the bedroom and the TV is located in the living room, i decided to put a router in the bedroom, and receive it's signal in the living room using a windows 7 laptop.Afterwards I connected the laptop to the TV through an ethernet cable, and bridged the two connections in Network Connections in Control Panel on the laptop. The TV successfully finds the laptop (and the router I think) but still cannot connect to the internet.

Can't Detect Wireless Connections When There Are Plenty Around?

Feb 19, 2012

My computer can't seem to detect any connections, saying only 'Not connected - no connections are available'. But that's impossible, as my flatmates' laptops could detect the wireless modem we have in our flat, not to mention all the other random connections floating around. Luckily, if I connect my laptop to the modem with a wire, I can get internet, but when I unplug it, same problem persists

Unable To Connect To Wifi On 2nd Laptop

Feb 23, 2011

I am attempting to connect to a residential wireless network on a router that was installed up by an engineer this morning.When the engineer was here he connected an HP laptop using XP to the wireless router. At first there was an issue with the connection (seemingly the same error message I am getting now), he did something to the wireless settings on the laptop, which stupidly I didn't see, and it successfully connected.When I attempted to connect my laptop to the same wireless router I got the same error message:'Connection Unsuccessful'.I clicked Diagnose Problem and got this: 'This computer has got limited or no connectivity'.I first selected the 'Automatically get new IP settings for the network adapter' but this didn't solve the problem. I then viewed the Wireless Network Security Settings and as far as I can see they are identical to those on the HP laptop that has successfully connected: [code] I then connected my laptop to the router using the ADSL cable and was able to connect to the internet, but I am still unable to get a wireless connection. When I view the wireless connections I am 'Connected With Limited Access'.

Windows 7 Laptop Unable To Connect To Full Wifi Connection

Jan 20, 2013

My laptop is reading a full WiFi signal from my router. I am currently connected to the router via Ethernet on the same laptop. I've been reading tons of old threads to troubleshoot this. I'm at a loss. I have used this current networking hardware for more than a year without any problems. I do have a pretty old router but my iPod connects to the WiFi no problem at the moment. Here's what I've tried so far:

- soft reset of router
- power cycle modem and router
- removed saved network information from the laptop

Laptop (lenovo G560) / Unable To Connect To Home Wifi

May 28, 2011

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.

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


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.

Only I have encountered this problem with my Philips 6356 router. I have spent 2.5 hours on the phone to Samsung and to the tech support from the store I bought it from and no one seems to be able to give me a definitive resolution! I can only assume the router is not compatible with the wifi connector in the laptop.

Unable To Connect To Home Network Over VPN From Samsung Galaxy S3

Feb 22, 2013

I am unable to connect to my home network over VPN from my Samsung Galaxy S3 phone. I have a Netgear WGR614v01 wireless router. This router has my desktop computer and windows 2012 server plugged into it. The server is a domain controller that has the following roles installed: DHCP, DNS, ADDS, IIS, and Remote Access. My Windows 7 Professional desktop is joined to the domain controller. The wireless router serves my netbook, smartphones, and ipods. They do not authenticate with the DC but do get a DHCP ip address from the server.I have my Samsung Galaxy S3 phone that I'd like to be able to use to VPN into my network. Here is what I have done;Disabled the DHCP service on the router. Setup port forwarding to forward PPTP to my server's static IP address on port 1723.I created a user on my DC for this purpose and enabled the account for network dialup service.I created a DHCP Relay Agent in the Remote Access MMC.I opened up the Remote Access app on the server's firewall.On my phone I setup a 'New VPN Connection...' I use the username/password of the user I created for this purpose. I put in my ip address that I have from my ISP.

Samsung R780 - Laptop Chooses Itself Which Router It Will Work With

Nov 5, 2011

My Samsung R780 laptop is just over a year old and has had problems connecting to the internet for almost its entire life.The problem I have is that it seems to pick and choose which routers it will work with, without any logical pattern. I'm in a shared house at the moment, and the router we used to have worked OK from what I could tell (although it had a poor signal). It never actually provided my laptop with a connection unless I boosted the signal, but I assumed that was just due to the fact that it was on the other side of the house.
