Network Completely Disappeared On MacBook?
Mar 7, 2013
My Network is gone from my list of available networks on my MacBook. I use s NETGEAR router, my network name is simply "NETGEAR" i have never named it anything else since installing this over 4 years ago. I have unplugged the power cord, waiting several minutes before plugging it back in. Also tried unplugging both the cable and the power cord. The router has no small "pin hole" that i can see in order for me to try to re-set it this way. It has literally disappeared from my Mac. Do i need to re-install using my NETGEAR cd?

I had a network connection to the main family computer that just completely disappeared after I got back on it. It had been on all day because it was defragmenting, but a few minutes after I got back on it (I had just sat down in the chair and sent a couple messages on a chat I was in and dismissed an "Oh, Windows Media player found another WMP on main computer! Wooo!" notification) and then it was gone.
I assumed the internet had crashed so I gave it a couple hours, no internet. I stayed up longer waiting, writing, playing some games, but nothing. I didn't check the Network computers thing until now.
Usually even when the internet crashes the main computer still shows up in the computer list but it was just mine then. It seems like it totally dropped the connection and it can't find it again when I try to create a new one. It's not like I watch p~rn or download anything I'm not supposed to download so...
And the network icon doesn't have a big red no connection at all x - It's just the two computers, no world icon, no x. I've tried booting in safe mode with networking, nothing, 'netsh winsock reset catalog' + 'netsh int ip reset.log, nothing, create new connection, nothing, and repair memory problems, nothing. : Microsoft Security Essentials found no viruses after a full scan, and it had been updated hours before the internet had a tantrum. I recently uninstalled Malwarebytes because according to a friend its update crashed her computer so I have no other virus scanner to use.
Oh, I'm runnning a Windows Vista Home Premium. Mine is genuine, it came with the computer, but my father had the bright idea to use -my- Vista disc to install it on the main PC, so it's all 'rawr not genuine' though as far as I know, my father's W7 laptop is still running just dandy.
We use a D'Link router, and it's worked fine until now. I don't actually know how my computer is connected, I'm pretty sure it's hardwired to the modem or router, but my father's is wireless. I've been searching like mad for the router's wireless USB thing, but it seems to have walked out the door.

I have been using the same modem/router since late july and I have never had a problem with my wireless. Then randomly this morning it was gone. I can see lots of my neighbors networks just not mine. I restarted my router multiple times and my computer. I am now connected to the modem by ethernet cord

Since always, my wireless connection had two options, the AARON network, which I always used and dlink (unsecured) which I never used. While connected to the AARON network, it lost connection, and dissappeared from my list of available connections. Is there anyway to get it back?

I have a laptop which has always connected to this wireless network fine until yesterday. The wireless network seemed to suddenly just disappear. There are three other laptops in the house which can still detect that wireless network and connect to it except that one now. I have restarted that laptop and the network reappeared and it connected. But when it was restarted again, the network showed just for a minute or so and the laptop cannot connect and then the network disappears. I've restarted it many times now and it just shows the network for a brief moment, trys to connect and then the network disappearsThis is the info for the laptop:ech Support Guy System Info Utility version 1.0.0.2OS Version: Microsoft Windows 7 Home Premium, Service Pack 1, 32 bitProcessor: Intel(R) Pentium(R) CPU P6100 @ 2.00GHz, x64 Family 6 Model 37 Stepping 5Processor Count: 2RAM: 2998 MbGraphics Card: Intel(R) HD Graphics, 1275 MbHard Drives: C: Total - 293422 MB, Free - 248128 MB;Motherboard: TOSHIBA, Portable PCAntivirus: Trend Micro Titanium Maximum Security, Updated: Yes, On-Demand Scanner: Enabled

I have Windows 7. I was using my wireless network fine but all of a sudden it disappeared. I don't even see it in the list of available wireless networks, even though other networks are showing. I have to use the ethernet cable to connect to internet.

I have a cable modem and it is attached to my computer, and it is also attached to a wireless router that we have been using for various wireless things around the house, like our phones and also the Roku box (for Netflix, etc).When I got the wireless router I was told to set up a private network and to use a password. I did this (though I don't remember how) and whenever a new device was first trying to access the wireless from the router it found the network name I gave, and I put the password in and used the wireless.
Last night we had some trouble watching something on Netflix using the Roku box and it connected to wireless but not to the local network. Then this morning it did not even find the wireless connection. I looked at my iphone and saw I had a strong wireless signal, but when I looked at the wireless settings it just said "linksys" (the wireless router) -- the network I had set up was gone!I looked on my PC in Control Panel, Network and Sharing, and the network I had set up and named does not pop up as one that's available.
However when I click on "Manage Wireless Networks" that wireless network I had set up is still listed there -- it's just not showing up. Somehow that got dis-associated with my router.how to re-establish the connection between the router and the network name/password I had established.

I'm trying to set up this 1130AG with a private wireless network and a guest wireless network. Initially it had just one wireless (private) and it worked fine, but then when I created the two VLANs for each SSID and then the guest SSID and now the guest SSID is visible/broadcasting, but the private SSID has disappeared or is off.
P.S. - It's a Cisco Aironet 1130AG (AIR-AP1131AG-A-K9) running 12.3(8)JEA system software and I'm using the web GUI (I'm not familar with the command line for Cisco products yet).

AT&T recently came out and replaced our Uverse modem, upon which iPad could connect to the new network, but neither of our laptops. I'm only a little technical with hardware/system issues, so after none of the more obvious troubleshooting issues worked, I started searching for more information and came across this site....great!! Eventually resolved the issue, suspect the wired connection through modem/router did the trick, but also updated the network adapter drivers. This (husband's) laptop was doing fine for a few hours, but then suddenly lost connection -- appeared that the network adapter was disabled. But when I went to enable it, it was gone!! It no longer appears in the Device Manager list at all. (It is/was an Atheros AR5700)

I'm on a home computer and we use a router to deliver internet connection to the multiple computers in our house.However, lately I have been noticing that occasionally one of the computer's, on the network, internet connection drops but yet all the other computers are still working fine with their internet connection. And the internet doesn't completely turn off, like there is no "X" on the two computer screens down below...it just loses its little globe icon...In order to get back the internet, you would have to basically disconnect from the internet connection network and then go back into it and it's back again.
I was wondering, because I'm starting to get suspicious, is it possible that somebody on the network in my house the deliberately found a way to turn of the internet access for one of the computers? I was alerted by checking different websites that it is possible that somebody on your own home network can "hack" into another computer, view its internet history, and even disable internet. How do I know this is happening for sure and take steps to stop it. I want to catch who is doing this because nobody is telling the truth .

Macbook Air, OSX 10.8.1, on a home network under a Cisco/Linksys WRT110 router, internet via Optimum cable modem TM822G. Other PCs are W7 and XP, plus an iPad, iPhone & droid.
This mixed setup had worked fine until Optimum (Cablevision) replaced our aging cable modem. Since then, whenever the Macbook attempts to connect to the network it kicks all others offline. The Macbook itself can't get online. The network created by the router remains OK, but the connection to the cable modem & internet is lost.A couple of years ago, when a W7 computer was first introduced, it had the same effect, and we determined that turning off IPv6 on the W7 computer resolved it. But since then, we got a new router and it had no problem with IPv6. I mention it only because the behavior is the same. But in this case, it's a new cable modem that was introduced. Now the Macbook Air, which has been working fine on the network, crashes internet.Unfortunately, the Airbook is a high school issued piece, so we can't turn off the IPv6, due to access restrictions; not that that would've necessarily done it, but it's hard to troubleshoot when you can't make changes.So the two pieces involved in the problem are the two pieces we have little control over.

I'm trying to connect my macbook air to a university Ethernet network. I'm using the apple thunderbolt to ethernet adaptor to connect, and it registers a connection in the network preferences, with an IP address and subnet mask number. However, it wont fill the router name, the DNS server number or the search domains fields.When I use google chrome to load a webpage it doesn't load, stating that a DNS lookup has failed.How do I get connected?

Running OS X 10.5.8 on an old MacBook Pro on a wireless network. It might be relevant that I recently upgraded the wireless router and the DHCP-assigned IP addresses changed. Before that, everything worked reasonably well.
I can connect to the MBP from Windows 7 computers on the network, logging in with a user name and password, and access the files there as expected.
But the MBP disappears from Windows Explorer after a few minutes. I can usually add it back (always checking the box to remember it) but it just keeps disappearing. Sometimes when it disappears, I can't add it back and when I try, Windows Explorer says, "can't find."
How can I get this share to stick?

We have a new DCS-5220 that we're playing with, seeing what we can do with it, and have a number of questions as well as one possible bug to report. I was somewhat surprised when tier 3 support said this was the best place to cover them all - including the bug.We are using firmware version 1.02, which is what the camera came with.
In the webgui, under Configuration > Tools > System > "Turn off the LED indicator" this is completely ignored by the camera. The red power LED is always on, and the green status LED flashes as long as it has a network connection. This is clearly a bug.What is the root password?Is there a URL we can pole for a static image? (ie.url... which would trigger a snapshot every time the URL is requested)Are there any shell commands for motor control? If so, what are they?Is there a shell command to retrieve logged in users? If so, what is it?Is there a shell command for controlling the LED activity? It would be really nice if the status LED lit green when there was someone logged on to the webgui. Perhaps this is the intended activity, and it not doing so should be filed away as part of the above bug..

I recently got my Cisco wireless system working a few days ago and am back with a guest network. Our wireless system includes one 2504 controller and 2 2602i access points. So, I want a wireless guest network completely isolated from the LAN.
Here is what I have done.
I have created a new internal network and assigned 192.168.2.1 to an unused port on the firewall and 2.2 to a new controller interface with vlan 10. I can ping both 2.1 and 2.2 from the firewall and the controller. Basic network connectivity is working. The DHCP server is setup on this same firewall and configured only for this port. This address is referenced in the controllers interface.
A new w lan was setup and enabled. The proper interface group was selected on the w lan. I have left the default layer2 security.
As far as AAA servers tab in this wlan, this is where I am a little confused. I wish to just have a single log in for this guest network. I wasn't sure what to do so I went over to the Security tab and created a "local net users" account. I do not know how to reference the use of this under wlan, security, aaa servers. Should I check the box that says "local eap authentication"?? If so, I don't have a profile name in the drop down. What I'm looking for is the username/password to be stored locally on the controller itself since there will be only 1 account.
Under wlan, advanced tab, I do not have "Allow AAA override" checked. Should I?
Lastly, when I try to connect the client, it is not pulling a dhcp address. I wasn't sure if authentication was required before dhcp or the other way around so I'm not sure what to trouble shoot first, authentication or dhcp.

I am using the RV220W with the latest firmware, I disabled all the four APs and also disabled the Radio, but the "Wireless" green light on the front panel still ON, why? How can I completely turn off the wireless?
Quoted from manual: WIRELESS—The Wireless light is green when the wireless module is enabled. The light is off when the wireless module is disabled.
Moreover I tried to disable the "Radio" while enabled one AP, I found that I can still connect to that AP, so what is the Radio's Enable/Disable used for?

I have a belkin N300 router that works decent most of the time, but anytime my roommate connects with her macbook pro the whole network becomes slow to the point of uselessness. If i block her computer using mac address filtering, the latency and download speeds are right where they should be, but as soon as i allow her back on ping jumps to 800-1000 and DL speeds drop to under 1mb.

I can usually figure stuff out for myself when it comes to computers, but to be honest I'm baffled. My HP 620 notebook wireless LAN has completely disappeared. I can no longer select anything to do with a wireless network, and it has also disappeared from the HP Wireless Assistant (which only has bluetooth on it - disabled by windows device manager?).
Anywho I did a quick internet search and it seems a pretty common problem with the HP series, and followed some advice they gave...
1) Did all the basic things (e.g. try and find a wireless network right click enable etc.)
2) Uninstalled/Reinstalled wireless assistant
3) Did some power off 30 second BIOS reset or something (literally have no idea what this is just followed advice)
4) I BELIEVE (note that this is way past my knowledge of computers) that I uninstalled the network adapter devices and reinstalled them on restart.
5) Finally I literally just took my laptop apart and took out, cleaned and replaced the wireless thingy
So all of this had no affect on my wireless LAN mysteriously disappearing. For those unfamiliar with the HP 620 it has a wireless on/off toggle button which is bright blue when working. Now however it is permanently orange and wireless has completely disappeared.

Ive just formatted both my hard drives and reinstalled win 7. Before this, my wireless connection was working just fine and after everything was complete with the win 7 installation a wireless connection cannot be detected. However, plugging an ethernet cable in allows me to access the internet just fine. I can also use the internet wireless'ly via my laptop, so its not a problem with my actual internet connection.After reinstalling I put my Gigabyte motherboard CD into the computer which ran some auto installations, one of which being a driver 'Realtek 8111/8168 LAN driver for gigabit (Win 7).' This didnt make any difference and I still could not access wireless internet. The list of component parts I got when I ordered my computer lists a '802.11N 300mbps PCI Wireless Network Card,' but no further info on make or model.

It all started when I wanted to add security to my wireless router (Linksys wireless-g 2.4ghz, 802.11g). Every time my IT guy tried to add the security, the tabs to enter the info would disappear. Since we'd been having trouble with this router for years, I bought a Linksys E4200 wireless-N router. He set it up, my son's laptop works beautifully (no he didn't do anything to his laptop except turn it on, and yes, I am sending this message via my son's laptop). Both of my laptops, however, are a mess. The IP address has disappeared (0.0.0.0), and after running all night, still cannot be found. My IT guy is absolutely baffled as to why this is happening. Before the router installation could be completed, he had to disable my Dell wireless network. He restarted it after the router connection was completed. Everything looks fine, but neither of my laptops will connect to the server, because THERE IS NO IP ADDRESS FOR EITHER OF THEM.

I have an Advent 5421 with Vista installed, it's nearly 3 years old and I have a few problems with it, but nothing too terrible, until yesterdy when I switched it on and found the wireless connection has mysteriously disappeared. When I try to connect it says there are no networks to connect to, which is obviously bollocks. The internet will now only work if I plug the cable in, which is no good as I share a flat with 2 other girls and if I do that, they lose their connection. I don't understand whats happened. I really am not computer literate at all, the only thing I tried was to make sure I had the latest software updates for my computer, which I did, but nothing happened.
