Wireless network disappears

When I install the Backberry link software on my PC with windows 7 , my wireless network stop working and can't be found or reinstalled.

Hi Jbrinkmann and welcome to the BlackBerry Support Community Forums!
If you navigate to your network adapters in Windows, does your Wireless adapter appear disabled? Do you see a BlackBerry entry within the network adapters?
Thanks.

Wrt160n my wireless network disappeared

I just purchased and installed a wrt160n. I named my wireless network and it worked fine. I even had my sister bring over her laptop and my network showed up on her puter and she was able to sign on fine. Later that evening I went to sign on and my network had disappeared. Iwould move my cursor to the icon on the tool bar and other local networks show available but mine is gone. Any clues as to what happened and/or what to do about it?

Try to adjust the wireless settings on the router....On the setup page,Change the Channel Width to 20MHz only and Chanel to 11...Under the Advanced Wireless Settings...Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304 Change the RTS Threshold to 2307 >>Click on "Save Settings"...power cycle the router and check if you can locate your Wireless Network and attempt to connect...

All wireless networks disappears time to time

sometimes the macbook cannot fined any wireless networks even not mine, at the same plase you have had connected with the same MB PRO. The problem is not with the router cause it cannot finde any other wireless networks which i'm pretty much sure that there is in the building. At some points when i restart the MB PRO the problem is gone and sometimes it is still there. As of this posting the MB PRO cannot find any wireless network but the IPAD is just fine.

I have the same problem with my laptop.
Allow computer to turn off device to save power: is not checked.
Advanced power options: the Wireless Adapter is set to "Maximum Performance".
I have a static ip set to 192.168.1.2
It was working for months then stopped 2 months ago after I had troubles connecting to a friend's wireless network unsuccessfuly. So I believe I must have changed something, but what? I have even removed the wireless adapter and re-added with
latest drivers.
I have 2 laptops on the wireless LAN. One is connected immediately when I open the lid after sleep, i.e. wireless adaptor enabled & I can browse and work online. The other has to enable the wireless adapter and re-connect to the router
which takes a minute or so. Not a showstopper because I am then up and running... but very frustrating.
I have trawled forums and searched for 2 months now. Could very well have missed the solution somewhere?
Good luck milky9311, I hope we both find the solution here. Thanks in advance for any suggestions.

Time Capsule - Extend a Wireless Network Disappeared

I was going in my Time Capsule settings within the Airport Utilities... I wanted to extend my wireless network so I clicked on this option. When I clicked it... the Time Capsule restarted and now is not showing up in Airport Utilities and there is a flashing amber light on my TC. Any way I can remove the extend my wireless network and put it back to Join a Wireless network?
Any help would be awesome...
Thanks.

We need a bit more information to understand your setup.
What version of AirPort Utility are you using? If you are not sure, open AirPort Utility and click on the AirPort Utility menu at the upper left corner of the screen. Then click on About AirPort Utility. Post back with the version number that you see there.
The Time Capsule cannot "extend" a wireless network unless it is connecting to another Apple router....an AirPort Extreme, AirPort Express, or another Time Capsule.

Hi odessit,
Are you sure the switch is on for wireless, #9 on the diagram.
Hit Fn + F5 and see if the wireless shows up there also.

"join a wireless network" disappeared

Hi, after I flashed my time capsule with the latest update and updated airport utility I cannot connect my time capsule to my wifi network.
The problem is simple: I do not have the option "join a wireless network" anymore. In the wireless tab I can only either create a new network, or extend an existing network. Anyone knows why?
Thanks in advance
Ben

ok I had to do an hard reset and it worked eventually
Hard reset:
Press and hold the reset button with a pen or pencil until you see the status light (LED) start to flash amber rapidly, which should occur after about five seconds.
Release the button, and the AirPort Base Station or Time Capsule will hard reset.

Wrt54gs router v.5 - my wireless network disappeared

Had a wireless network for a year, and yesterday it was no longer broadcasting. It does not appear on the available wireless network screen. Tried to access the router, and cannot do that either. I am clueless what happened and what to do about it. Any ideas? Thanks

Have you done a recent firmware upgrade or anything? I had the same issue, and once I reset the router to factory defaults, the SSID that the router was broadcasting was an unsecured Linksys network. Go into the router settings by typing 192.168.1.1 and find the wirless settings. Look under SSID and see what it says. Change it back to your original network name and secure it.
Hope it helps.....Rick

List of Wireless Networks disappear/don't show

I'm having major problems with my Macbook Pro. It has all the latest upgrades for Leopard (just checked again for updates - nothing more available). This was a native installation of Leopard - not an upgrade from Tiger.
When I FIRST start my laptop, it connects to the #1 preferred network. But I have 2 routers at home (and I live in an apartment so there's about 12 networks around me) and I often need to switch depending on which end of my condo I am in (concrete walls suck for signals). Any how this is not a signal issue however, as this problem happens when I am in the same room as my router.
When I click the Airport button on the top, the dropdown menu comes out, and fora split second it displays all the networks. But after about half a second (which is NOT enough for me to find and click another network I need to hook into) the list disappears, and truncates to the one I am already on.
So from there I tried "Join Other Network" and it opens a new window, asking me to enter a Network name and what not. When I click on "Show Networks", it used to display all the available networks, but it displays NOTHING - not even the network I am already connected to, using fast and normal internet.
So basically I need to turn my Airport off, open the preferences, change the order of preferred networks on the list of saved networks, and then turn it on again.
Now here's the killer - 50% of the time, after reconnecting, or after waking up from sleep mode, my laptop will FAIL to find internet connection from any of my two routers (while my roomates are doing fine) even with the proper IP addresses and Subnet masks assigned. it basically looks like a healthy connection but I get no internet browsing, email, MSN, nothing.
So basically every time I move from my living room to my bedroom, there's a 50% chance I need to reboot my computer. And there's a 100% chance I need to stumble around settings to make sure my computer finds the right router.

Try the following:
1. Delete Preferred Network(s)
o System Preferences > Network > AirPort > Advanced > AirPort tab
o Under "Preferred Networks," delete the network(s) you regularly use from the list.
2. Delete AirPort Keychain Entries
o Launch the "Keychain Access" application located in Applications/Utilties.
o Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
o Restart, or log out then back in.
3. Add Preferred Network(s)
o System Preferences > Network > AirPort > Advanced > AirPort tab
o Add the preferred network(s) using the "+" button.
o Restart or log out then back in.

[Macbook] Wireless networks don't appear, or appear then disappear

Two windows vista laptops can scan and find several wireless networks and connect to one (unsecured). However my Macbook, sitting inches away, does not list any networks to connect to. Sometimes, upon restarting, the networks will show up, but when trying to connect it says "Connection timeout". Then, the networks will disappear from the list. Has anyone had a similar problem?

when you are searching for access points is your location set to automatic... if you have an local static IP entered into the laptop then the laptop will only seach thoes networks...

Added a scanner with Secure Easy Setup and my wireless network has disappeared?

I just replaced my fax/scanner. I have a secured wireless home network. I installed the fax/scanner with Secure Easy Setup. The fax works - but my home network as disappeared!!! Where did it go? Do I have to start over and reinstall my whole wireless network? It took me forever to get it working the first time! HELP!!!

when u run easilink again it will give you the chance to change some settings wirelessly, it could be that you have changed some settings and missed that part...
you could check that by accessing the set up page of the router 192.168.1.1

Disappearing hotspot wireless network

Background:
Connecting two devices to an iPhone 4 Hotspot (AT&T).
Problem:
The wireless signal disappears and the devices lose internet access.
The iPhone still displays "2 connections", but the devices themselves do not see the wireless access point.
Attempted troubleshooting:
Turning the Hotspot OFF/ON makes no difference. The wireless signal does not appear.
Rebooting the iPhone does fix the problme. The signal reappears.
What's the cause? What's the solution?

I would suggest you to readjust the wireless settings on the router...
Login into the Linksys GUI by typing 192.168.1.1 in the address bar...Click on wireless tab and change the Channel Width to 20MHz only and Channel to 11>>>Click on save settings.Under Wireless tab click on subtab Advance Wireless Settings tab and Change the Beacon Interval to 75,Fragmentation Threshold to 2304, RTS Threshold to 2304 >>Click on "Save Settings"...

Time capsule blinking amber and my wireless network has vanished after factory reset

Hello,
I have an Apple Macbook aluminum body with a Motorola cable modem hooked up to the Time Capsule which acts as my router. After turning the power off in my home, the internet has not been working. The light on the TC was green, but I had no internet because Airport had a "self-assigned" IP address and may not be able to connect to the internet. Then, I decided to do a hard reset and restore my setting to factory. The light on the TC is blinking amber. When I go into Airport Utility, it gives me this message: "Airport Utility was unable to find any Airport wireless devices". On top of all this, when I did the hard reset, my wifi network is not on the list of Airport networks in my range. It has completely disappeared. I have all the wires connected properly to the router and TC. Please help, this scenario is very frustrating.

If you performed a factory default reset, the TC is now broadcasting a wireless network with a name like Apple Network xxxxxx, where the "x" could be either a letter or number.
You must first log on to this wireless network (there is no security or password) and establish a connection.
Then, if the TC was reset properly, you will be able to open AirPort Utility and re-configure the TC.
When you click Update to save your configuration settings, the TC will "dsiappear" from AirPort Utility. This is normal. Close AirPort Utility and wait for the TC to restart.
Then log on to the "new" wireless network that you named during the configuration.

MacBook Pro Can't find home wireless network

I've been having some issues getting my macbook pro, running OS 10.7.5, to find my home wireless network. The network doesn't show up when it searches automatically, and when I type the network name in to find it manually, it says no network found. The computer connects to all other networks and finds then with no issues, and other MacBooks are able to find my home network and connect to it again with no issues.
The computer used to be able to find the network, and then it just stopped working. I have tried all the standard fixes, resetting the router, computer, PRAM, forgetting the network, deleting the key from keychain, but nothing seems to work. I tried googling the issue, but wasn't able to find a problem similar to the one I have.
Any advice would be greatly appreciated.
Thanks

Still having problems with this.
I have upgraded to Mavericks, hoping that the problem would be fixed, but it hasn't. I still get all networks completely disappearing - even if I search for them they are not found.
But I reboot the computer and it works! But when I am in OS or Bootcamp mode and put the Mac to sleep, it does not see the networks again! I have to reboot the computer for it to work.
I have even got a new router which can receive the b,g and n signals etc. as I was told by a Mac techie here that Macs 'look' for the n signal but can also work with the b and g signals and THAT maybe my old router only transmits b and g or something like that .
This, to me, sounds like a Mac software problem. I had a similar problem on a previous Mac on my "old router" and a totally different router in a different country's telephone system.
I now have the same problem with a new MBP on a new router!

Can't connect to wireless network on bootup like before

Hello all. Well, I seem to have run into some difficulties here while configuring my system. The thing is I cannot connect to my wireless network on bootup anymore. I stayed about 4 months without using Arch Linux, then I decided to reinstall it from the ground up on the SAME machine, which has suffered NO changes; it is the exact same computer. The only change since then is that I changed my WEP encryption key on my router. I had a functional rc.conf file which I keep just for taking a look at while I'm configuring the system. The Networking section follows:
# /etc/rc.conf (NETWORKING Section)
HOSTNAME="ArchPC"
wlan0="dhcp"
wlan_wlan0="wlan0 essid MySpot key 0123456789ABCDEFABCDEF1234"
interfaces=(wlan0)
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
The only thing I changed from my previous rc.conf was my WEP hex key, which I have already triple-checked. I used the same hostname (which is also correctly configured in /etc/hosts) and the essid is the same. In 2 years of Arch I used this configuration file and it worked flawlessly, but now it simply does not work anymore for boot-up connection. I simply get a FAIL after about 30 sec in '::Starting Network' on bootup. Then, by issuing 'iwconfig', I can see that my interface (wlan0) is up and the ESSID is set to "MySpot", but the access point is not associated. I do not know what is going on, as it never happened before. However, it works just fine if I do the step-by-step manual configuration from command line after my system is up and I can get internet access in such a way without any problems. Never did it before (so I do not know if this was the case for my previous installations), but by running 'lspci | grep -i net' I do not see my wireless extension listed, although 'iwconfig' shows it just fine. I am trying to make it work using rc.conf just as it did before. As I mentioned, my network connection is working, but not from bootup as it did before, so I do not know what to do. Did anything on Arch radically change since then? Couldn't find anything on the wiki pages besides using another network start method. Any help is greatly appreciated...
Edit: I just found out that my wmaster0 is missing...could that have anything to do with my issue?
Last edited by gabscic (2010-04-04 06:45:23)

Just for the sake of not letting this go without any answer, I've just done a full system reinstall and now I've got back my wmaster0 (the driver module for my wireless network card is rtl8187). Searching the internet, it seems that wmaster0 is an internal master device that is to be used by the module, and not the user. The lack of wmaster0 may indicate that something is amiss on the driver installed on your system. Now that I've got it back, my rc.conf file (described on previous post) works like a charm. However, I remember I did have wmaster0 on my previous Arch installation and it just disappeared all of a sudden. So far the only thing I've done different is that I have not yet upgraded my new installation, so my guesses are that something on the upgrade procedure is breaking the driver in some way. Maybe all those package renames and such? I'll upgrade my system later (don't have the time now) and I'll get back here with any new findings. Regards...

Connecting AX to mixed wired/wireless network

I've got a networking issue that I can't seem to solve and could use some help. I have a old house that, while not terribly large, has very thick, radio opaque walls.
I use a cable modem connected to an Airport Extreme which creates a wireless network within the house (which I extend around the house with a couple of Airport Expresses). I also have two computers wired via some VERY long CAT5e ethernet cables to the same Airport Extreme - a MacMini in my kitchen and a MacPro in my office (which is detached, across the yard from the main house). Right now I also use an Airport Express in my office to extend my wireless network for my clients who come to the office with laptops, etc. and also for my iPad. But the wireless signal is so weak out in the office that even with the Airport Express repeating it, it's very slow and spotty.
So, I bought an Ethernet switch, thinking I could split the Ethernet coming into the office and run one directly into the MacPro and the other into the Airport Express. I figure it's not hard to configure the Airport Express to create a NEW wireless network with the data coming in via Ethernet. However, what I want to do is create a node on my EXISTING wireless network (so my devices can see each other), just using data coming from the ethernet port instead of repeating the weak wireless signal that's reaching the office from the house. Is this possible? If so, how do I do this?
By the way, I have both old (G) AX's and well as a couple of new (N) ones. Right now the new ones are in the house and an old one is in the office, but I could move things around if it made things work.
Thank you.

Hey Bob,
I set up the Airport Express as you described and, while it worked at first, I'm running into some difficulties. Basically, the AX unit tends to disappear from the network after about an hour. It's very strange because, like I said, it works at first and I have great signal out in the office then... poof!... it's gone. And it doesn't just disappear from the wireless network. Both my MacPro and MacMini (which are connected via ethernet) can't see it either. I have to unplug/replug the unit to get it to show up again.
I thought it might be the particular unit. But I've tried two AX (G) units and my old AirPort Extreme (G) UFO shaped router all in the same bridge configuration and they exhibit the same behavior -- working at first then dropping off the network and requiring a reboot to reappear.
Do you have any thoughts? I'd be most grateful.
