Satellite L300-135 sees WLan network but won't connect

Well, (new laptop) initially it worked with my BT hub at home... then decided to stop working - recieves no signal or response from the router - even though other laptops in the house can connect without any problem
and now the wireless does not work - ie. I can see the wireless connection but cannot connect.
I'm sure the wireless is not switched off (before anyone suggests so)
I searched for more up to date drivers but nothing seems to work.
Please help!

Hi
First of all you should check if your WLan card has been recognized properly.
I mean you have to check it in the device manager!
Your WLan card should be the Realtek 802.11g(RTL8187B)
Download and install the newest WLan driver from the Realtek page.
Then update the BIOS.
Finally configure all the WLan settings again.
In device manger -> WLan card properties -> Advanced tab disable the power saving settings and check other settings which could affect the connectivity.
Good luck

Not able to connect to wifi using iPhone 4 with OS5, sees the network but won't connect.

Recently upgraded my iPhone 4 to the OS5 and I keep having sporadic issues with connecting to my home wifi, it sees the network but never connects. I turned of Location Services and Cellular Data for that had worked sometimes, but now it just keeps spining and never connects. I tried to reset network settings, reset my wifi router and reset my phone and nothing, it will connect at my church for example and other places but not at home. I have MAC addressing security set on my router and I verified my iPhone MAC address is authorized. Any other suggestions?

Try restarting your router first, turn it off for a minute then back on. then go to settings on your phone, then wifi, tap on the blue arrow to the right of your wifi 's name, then tap forget this network. Then go to the home screen, Then hold the home and off button down until the apple symbol comes up. Then go back into wifi and try to connect.

IPhone 5 Wi-Fi problems: "sees" the network, but won't connect

Hi everybody,
For the past 3 days I've been having sudden problems with my brand new iPhone 5 (version 6.0.2 {10A551}).
It just won't connect to the internet, no matter what I do. It actually "sees"the availble networks, but when I put the password in, it says"Unable to connect to the network".
I tried Resetting Network settings and All Settings, to no avail.
The irony is that I get Facebook notifications, App of the day Notifications, occasional mails, but nothing else. Email sync is erratic, and always with the little round circle where the WiFi icon should be. No Whatsapp, Viber, etc.
I'm totally baffled and equally desperate.
Can anyone help me please?
Many thanks in advance and Happy New Year to all thread readers.
Joyce

After connecting to Bluetooth keyboard, iPad 2 will not connect to Internet (wifi) at all. Wifi is ok, have tried turning off bltooth, wifi on iPad. It sees the network but won't connect. Help? Have also reset network settings etc

My iPad wifi was working great until I I connected it by Bluetooth to a keyboard (zagg). It was the first time I'd used Bluetooth
Immediately Internet was dropped on my ipad. My iPhone was and is still connected no prob. And I cannot get the iPad wifi to work again....at all!!!
This is major as I am away from my desktop for three months. Any fix cannot involve being at my desktop with iTunes which is 10,000 km away
So far This is what I've tried based on other discussions-
-turned Bluetooth off and unpaired to keyboard which was also turned off
- turned iPad wifi off and on (several times)
- forgot the network I useArrive Jul 19 depart Aug 25th. Originally it was Sept 9.
-- reset network settings
What happens is that the iPad sees the network and I enter my password. But, instead of getting "check mark" indicating a successful connections it keeps "circling". Sometimes the airport bars will show, but disappear or flicker. It never connects with a check noted in settings. Any attempts to use internet confirm there is no connection
My network is not a cafe or public network. It is one I regularly use here at my family's home where I am visiting
Any ideas!

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Windows XP laptop sees wireless network but won't connect

I set up a wireless network on my airport extreme using my MacBook. The McBook runs great on the wireless network. My old Dell laptop running Windows XP sees the wireless network I created (with full signal strength) but every time I hit "connect" I get the following error message, "Windows is unable to connect to the selected network. The network may no longer be in range. Please refresh the list of available networks, and try to connect again." When I referesh the list, the wireless network is still there, and i still cannot connect, getting the same error message.
Any suggestions?

Hello apetera. Welcome to the Apple Discussions!
Per chance are you using WEP for your wireless encryption?
If so, one of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
In order to make things easier, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling the use of simple easy to remember WEP password rather than lengthy HEX keys. The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AEBS will be hashed differently on a non-Apple client and vice versa.
You may find the following articles helpful:

o Apple article, especially the part about "Third-party client to Airport".

I installed a new wifi router and airport will not connect automatically to it. It sees the network but will not connect unless I tell it to.

I installed a new wifi router and airport will not connect automatically to it. It sees the network but will not connect unless I tell it to. I can't find anywhere in the utility or network preferences that will allow me to choose this router as the default. How do I fix this? BTW I'm using Lion.

Are there any previous networks that you have used that have the same password as Molly? YES
Using System Preferences > Network > AirPort Advanced again, you need to remove any listings of previous networks that used the same password as Molly. Click the name of the network and click the - (minus) button at the bottom of the list of connections.
Also delete any other networks (except Molly at the top of the list) that might have used the same name...Molly in the past.
Delete any other networks that you no longer need so that your Mac will search for networks more quickly
Click OK, then click Apply
Open KeyChain Access and look for a listing of any old networks that you no longer need. Click to highlight the name of the network, then click the Delete Key on your computer.
Then look for any old networks that might have used the name Molly in the past and do the same for them.
Then look for any old networks that might have used the same password as the password for your "new" Molly network and delete them in the same way
Click the KeyChain Access menu just next to the Apple icon in the upper left corner of the computer screen
and then click KeyChain First Aid
Enter the main administrator password for the Mac you are using and highlight the Repair button. Then click Start. You will see a message that repairs have been completed
Quit Keychain Access
Power down the entire network...all devices...order is not important
Power up the modem first, then your main router, the other devices one at a time
Log on to Molly and see if the Mac remembers it after a few tries. If not, I'm afraid that you will need to change the name of the wireless network and password on your router due to corruption issues on the Mac. You have done everything possible without re-installing the complete operating system.

Glad to hear it is all straightened out. You are right about the upgrade cost. That is one reason why Adobe switched to monthly licensing—no more upgrade cost <g, r, & d>. Of course we do have nearly monthly product upgrades. It is almost like playing whack a mole.

Hello lucky3480;
I don't know what else to do. I'm thinking of possibly returning the unit and purchasing a wireless internet card to install in the tower. Any help you can provide would be great. Even suggesting a good wireless card at this point
Well it looks like you're not having any luck at all with this AX set up but please don't give on it just yet, it's a good choice for extending your Network. Your on the right path, just going backwards and in the wrong direction. You'll learn a lot about stuff this way but may lead to other issues.
Before I continue, let me know if you have returned the AX or still need help. Here's a link to Apple's PDF about [Designing AirPort Networks|http://manuals.info.apple.com/enUS/Designing_AirPort_Networks10.5-Windows.pdf] Click on it to open in Safari but then save it to your desktop. Now open it from your desktop and start reading Chapter 3, page 42.

Windows XP MCE sees network but won't connect

Hello
I've managed to get my AAEB working with two of my computers, one is a regular desktop which is connected through the wired outputs, this works like a charm.
The other is my personal laptop, an Acer Ferrari with Windows XP pro, this now also works perfectly on the wireless system.
Now I'm trying to get my brothers laptop to connect to our network and internetconnection through the AAEB. His laptop sees the network but when I try to connect to it it's not possible, I never even get to the part where I have to enter the password.
I'm using WPA/WPA2 for security and as stated having no problems on my own computer that's running WinXP Pro, but this one that runs WinXP MCE can't connect.
I've tryed disabling the security on the AAEB and when I do that it's possible to connect with the WinXP MCE.
Please help :'(

Thank you very much for your suggestion.
It might be me who doesn't understand fully what you mean but my problem is that I can't get the PC to connect to the wireless network.
If I plug in a ethernet cable everything works like a charm however. But I just get an error when trying to connect to the Wlan that the network might not be available anymore, eventhough I'm using it on my personal laptop at this very moment.
edit in response to your post also, I never get far enough for it to even try to recieve an IP

Laptop sees Photosmart on network, but won't connect

I have a Pavilion dv4 with Windows 7. I have a Photosmart C4795. My printer used to be hooked up to my desktop, but my HP Desktop has crashed and it's trash. So now I'm trying to hook my laptop up to my printer on the network. For two days, I was able to connect and download with no problems, but my laptop would never print. Wouldn't even do a test page. Uninstalled and reinstalled at least 10 times. I ran the scan doctor and it said there was nothing wrong with my printer, but it wouldn't print a test page either. It then had me do an internal test page and that one work, so it diagnosed that the software was bad.
All of that was yesterday. NOW TODAY, I uninstalled and reinstalled the software. It's the most up to date software and drivers from the HP Support page. Now, my printer recognizes that the printer is on the network, but won't install the printer. It did the diagnostics, then brought up the screen where it showed my computer on the left, modem in the middle, printer on the right. It gets about halfway through setting it up, then quits and says it can't complete. I ran the scan doctor again and it says that the full software version is not installed. I JUST downloaded it from the website and installed it twice and it won't work. The version I download from the website is around 146mb, but when I download it from the scan doctor page, it's over 200 mb. I run that software and it is exactly the same.
I have tried to set it up via usb. It gets to the 7th of the 8 steps, then it won't go any further. Again, the printer is detected, but it says the appropriate drivers aren't there.
I have tried to set up it's own port using it's USB and a different driver, but that gives me an error. Unable to install printer. Operation could not be completed (error 0x000003eb).)
Would someone please help me, and then if I reply with what it is doing next, please respond?
Please help me get through this. Two days now and I don't have a solution.
Just me, friebe13

Hi,
If you are using AT&T wireless router to connect the Photosmart to network, you can refer this link for a solution :

Try restarting your WiFi router by removing power to it for 30 seconds.

Can see network but won't connect

I have three computers using an Airport Express base station. They've worked just fine until this morning, when I bumped up security by setting WPA/WPA2 Personal.
Since then, the Power PC G4 (OS X 10.4.11) can see the base station's network, but will not connect to it.
I've done multiple restarts, verified permissions, unplugged and replugged the base station and also the cable modem. Nothing has worked.
Please help.

Yes, if I set "Security" to "None," the G4 can connect. But I set it up after I found my next-door neighbor's shared files folder listed on my network this morning. He's an OK guy, but it made me aware of how vulnerable my network is.
My firmware is version 9.52. I've prowled the Apple site looking for an indication of whether that's the latest, but couldn't find one. My "Software Update" says everything's up-to-date.

Apple tv is connected to the network but won't connect to internet?

My apple tv 3 is connected to our wireless network but will not connect to the internet. I also cannot turn on home sharing. All the other wireless devices in our house have no problem with the internet. I have hooked the apple tv up to the computer and restored the factory defaults but that did not help. Any suggestions?

have you tried connecting using ethernet to see if it's a wifi issue ?
and have you verified that the required ports are allowed on the network ?

Airport card sees networks but won't connect.

I'm not entirely sure why.
Wired ethernet works fine, and our G4 Desktop's Airport card works fine.
Mine, however, is being a bit wonky.
I shut the computer down for the night about a week ago.
Brought it back up and got the "There was an error joining AirPort network *our SSID*".
Fine, sometimes it does that. I wait and it usually works in a few minutes.
Not this time.
We rebooted our Linksys WAP and our Cisco router, no good.
Shut the iBook down again, reseated the Airport card, fired it back up and paid close attention to the verbose boot this time.
Nothing abnormal, no errors.
Still no wireless connection.
I've tried connecting to other wireless networks around us, and we even defaulted the WAP back to out of box state (i.e. it was wide open and not passworded), but nothing. Every other wireless device in the house (G4 desktop, Dell laptop, and a Toshiba tablet) works just fine.
The computer can SEE wireless networks, but it can't connect to anything.
There have been no major system updates recently, and the only program I've installed in the past 3 MONTHS has been the World of Warcraft Burning Crusade expansion. Nothing else has changed, which is what's stumping me.
I'm starting to wonder if:
A) I'm overlooking something incredibly simple.
B) My airport extreme card is dying.

firstly, tesserax, a tremendous thank you for your help. unfortunately, i tried each step you suggested, but the problem continues.
step 1: i have tried and failed to connect to several different networks in a handful of locations (home, work, friend's house, local coffee shop, etc.).
step 2: i have disabled my own wireless encryption as well as the wireless encryption at a friends house, however, to do so i had to use their ibook, as my own either didn't list the base station in the AirPort utility (although it did list the base station in the AirPort status pull down), or it asked for a password even though the base station wasn't password protected (maybe this may add some insight into the issue?).
step 3: i have connected the computer directly to the modem using an ethernet cable and was able to go online - perhaps this means the problem is related solely to the card.
step 4: i moved the the com.apple.networkConfig.plist file and and the SystemConfiguration folder to the desktop and restarted. unfortunately, OS did NOT rebuild the files. instead, i had to go through the network diagnostics to rebuild them manually. while the files were replaced, the problem was not solved.
step 5: i reset the PRAM, but the problem still exists.
step 6: i reset the PMU, but the problem still exists.
i then tried various combinations of your suggestions, including moving the files out of the preferences folder and then reseting the PRAM and the PMU, but still nothing.
after having attempted every fix i could think of (and that was before posting to this forum) i did a full erase and install of the OS. since that's usually the cure all to whatever ails the computer, it's my assumption that the issue is a physical (hardware) one. that said, if you have any other suggestions i will be more than happy to give them a shot.
thanks again,
brad
