Satellite A200 can't see wifi

Hello,
I meet strange problem, till now my wifi has working good, but today, i don't know why, my laptop can't see any wireless networks, like the antenna was turn off. Of course it is on, i see orange light that signalize that. I try to reinstall drivers, but it didn't help.
LAN is working.
My computer: Satellite A200 1M4, Windows XP Professsional SP 2

First of all you should check if the WLan card is still recognized in the device manager.
If yes -> you could still try to remove and to update the WLan driver.
Furthermore reset the WLan router. The router reset is necessary and mostly it solves some strange connectivity problems.
Last but not least use the FN+F8 key combination to enable the WLan antenna

Hi folks, you might know how to fix this: my wifi shows (no hardware installed) then I went to system preferences and deleted the wifi connection, I went also to system information and I can not see wifi listed on Network, how can I create a new wifi ?

Hi folks, you might know how to fix this: my wifi shows (no hardware installed) then I went to system preferences and deleted the wifi connection, I went also to system information and I can not see wifi listed on Network, how can I create a new wifi or simply solve this, I have tryied shotdown pressing keys like P and R, option, etc. Please help me .

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Error message on Satellite A200: Can't open ACPI ATK0100 Kernel Mode Driver

Hi,
I have Satellite A200 laptop
When i start the windows(vista) I get the following error: *"Can't open ACPI ATK0100 Kernel Mode Driver.* " !!
I've installed all drivers and the error remains.
I've installed all the drivers from the Toshiba website , but the issue remains.
Device manager shows me that every device is working properly.
Has anyone got an solution?
Thanks

ACPI is the power management facility for your Windows Operating system. If this is failing you may have to run a system recovery on your computer. You can do this with the hidden partition on your hard drive, however this will erase all of the data on your machine. If this doesn't solve the problem, you may have to consider getting your hard drive checked for bad sectors as this may have failed.
Hope this helps. :)

After install of 2.0 Playbook can't see WiFi and Bridge Apps won't execute

Last weekend I finally bit the bullet and installed 2.0. I installed over WiFi but after the install the Playbook could no longer detect my D-link router (DIR-825). My Bold 9700 WiFi connection is fine. Also, I updated the Bridge software on my phone and the Playbook recognizes the connection but none of the Bridge Apps activate when I touch their respective icons. I've rebooted (3 finger) several times to no avail. I also tried manually connecting to the WiFi but without success. There also seems to be considerable battery drain compared to the 1.0 release despite keeping the Playbook in standby. I assume I'll have to re-install 2.0 and would appreciate any other suggestions as well as any guidelines on re-installing to ensure success and to avoid loss of apps and data. I did a full backup prior to the 2.0 install and will do another data backup prior to reinstalling.

Since we upgraded the software, nothing but trouble. Can't see wireless network, can't connect manually to the computer (to copy files off), can't connect to wireless manually. Totally useless.
Can ANYBODY help?

MacBook can't see wifi network

Hi there,
Please help! I'm setting up a wireless network and my macbook can't see the wireless network.
The bizarre thing is that my friend's macbook sees it and connects with no problem. My macbook sees other wireless networks, but not mine! What's going on?!
I have done the following
- checked that it's turned on. (turned airport off, and back on, and restarted the computer)
- checked that the router is broadcasting the SSID
- checked the network name and password are correctly entered.
- tried entering the name/pwd directly into the "preferred networks" setting of the Network Preferences pane
what else could I do? I'm at a loss.
Please help.
thanks!

Solved my own problem.
Although the wifi router was set to broadcast the SSID (and only one of my macs could see it), I changed the settings so it was NOT broadcasting the SSID, then plugged the appropriate settings into the System Preferences pane, and it worked.
crazy. but it works.

Can't see wifi network

Today I got a wimax modem with built in wifi (greenpacket DX230). There is no customization of the device at all. The SSID and password are already printed on the device and are supposed to work without setup. However, I cannot see the network from my macbook running snow leopard, even if I am right beside the device. I have checked several PCs and they can all see the network, and my iPods can also see the network. I have yet to try another mac (will try tomorrow).
Does anyone know why this would be? I thought wifi was a standard and that there is no deviation from it? Why would my ipods be able to see the network but not the macbook? Kismac doesn't even show the network

It might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort menu bar item to turn AirPort off, then on again.
2) Try to select your Wi-Fi network from the AirPort menu.
3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease".
6) In the folder /Library/Preferences ( not <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
They may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

Satellite A200 - Can't find Sleep & Charge option in BIOS

I have been told that turning "Sleep to Charge" on in the bios of my satellite A200 will help my iPhone connect with iTunes without freezing it. I have downloaded the latest bios (2.50) and cannot find anywhere in it that will allow me to turn on "Sleep to Charge".
Can anyone help?

Hi
If you cant find this option in BIOS your notebook doesnt support this feature. With this feature you can only charge USB devices while the notebook in sleep mode. It has nothing to do with the connection while notebook is running.
So I doubt that this can solve your problem. You have to search for another solution.

Playbook OS 2.0.0.7971, Android Player can't see WiFi

Hello Everybody,
Yesterday I got my Playbook. During setup I got updated to OS 2.0.0.7971. Visited Playbook appstore and installed Wattpad (which apparently is an android app that runs on the integrated Android Player (not available as a separate app anymore)). Everything works all right except that it cannot see my WiFi connection and hence, cannot do anything useful. I also sideloaded Kindle, Pulse reader, and some other apps that run on the Android Player. NONE of them can access the internet (can't see the WiFi). As a result, I cannot even register my Kindle app.
Anybody having similar issues on the OS 2.0.0.7971? I think my Android Player version is 2.0.0.56 (that is what it shows at the bar below). Please suggest what I should do to fix these. Without the Kindle app, the whole Playbook thing kinda becomes pointless to me :-(
Please help.
Thanks and Regards,
Aditya

IPhone 4S - iOS 6 - can't see WiFi networks

I have a strange problem with my iPhone. It's a locked iPhone, bought from Vodafone from my country. I use it locked and un-jailbreaked. I went in France for 2 weeks where i had my Roaming active, but i didn't used cellular data, only WiFi. Now, back home in my country, it seems that i can't see wireless networks. I tried to reinstall, update to the last firmware, it seems that wireless appear for 1 second when at first start, then it disappears and i can't see no more WiFi networks in list, tho there are like 10 networks around me.
Any ideas? Or someone else had the same issue?
Thanks,
Nick

i went to Vodafone. They said they will replace it. It seems like a manufacturing defect.

TS1398 after upgrade to ios 6.0.1 WIFI is very weak or can not see WiFi networks (iPhone 3GS)

Is there a way to restore the WiFi functionalilt of the iPHONE 3Gs after itw was upgraded to IOS 6.0.1 ?
I see there are lots of things on the internet, but nothing that actually works !

Thanks Chris for your solution.
But just for you know that I bought Apple to get the 'after service', they should've warn the users not to upgrade to a higher OS if it can caused the phone 'dead'. Mine was totally unusable when it's just been upgraded. It stayed in the recovery mode and couldn't be restored. So I brought it to the nearest store and they did that to me, and eventually the phone is working, only it cannot detect my SIM Card...
The problem is not about upgrading an iPhone to a newer version of iOS. Your problem was upgrading a hacked phone, one of the well known consequences of which is re-locking and/or bricking the entire device when restoring in iTunes. You chose to hack your phones firmware and operating system, so you must accept the consequences of going outside the bounds of normal use that Apple prescribes and supports.
Had you not hacked it in the first place, you likely would have never had a problem, and if you had, Apple would have offered support to deal with it. Your choice, your decision, your consequences.

Can't see wifi networks?!

Unlike any phone I've ever had before, whenever I switch on wifi on my E4G, I cannot get an automatic list up of available networks in the area. Instead, I have to go to Settings/Wifi/ to see what is available and THEN choose from them. After that, I can connect no problem. I've never had this before and am presuming it can't be built so that you have to do that every single time whenever you switch it on?! I'm used to switching on wifi and, unless you have a saved network in range which it connects to automatically, a screen pops up showing you all networks within range so that you can then select one, which is the normal way of choosing a new one when you go to a pub/restaurant etc., so that you can then put their passkey in to store it for future visits. Please don't tell me this phone is so backward that it's missing what even the most basic phones do as standard for something as important as wifi?? The only thing I can presume it might be is if I go into Settings/Wifi/Menu/Advanced, there is a tick box at the top saying Network notification. I am a bit loath to think it's this as there is smaller text underneath saying 'notify me when an open network is available'. To me, that reads that it'll tell me when an unsecured network, free to simply use at will, is available but am I reading that incorrectly and an open network may well be locked/password protected, and not just one that's free?

This phone is designed to connect to trusted/saved WiFi networks by default and will do so whenever WiFi is turned on. It will not show a list of available networks when WiFi is turned on.
The setting you've found (Setting/Wifi/Menu/Advanced/Network notification) will tell you when a unlocked/open network is available - it won't tell you if a network is available if it's protected with for example WPA.

Satellite L655 - Can't see the FN button on top of my screen

Hi ,
I have a L655 and when I press the FN button I dont see the help on top of my screen that I use to see.
Can you tell which of the TOSHIBA Help programs is the one that saws me the fn help bar on top of the screen?
Thank you.

Hi iznogood,
The FN bar that you mean is called Flash Cards. They appear if you press FN key or an FN key combination like FN+F8.
The Flash Cards are controlled by Value Added Package and Flash Cards Support Utility. I would recommend reinstalling both tools
That means remove both tools, restart your notebook and start with installation of VAP and then Flash Cards Support Utility.
You can download both tools here:

Can't see wifi networks or connect to my own?

I'm going to start by saying I have an iPhone 4s and it's not that old, and the version is 6.1.3. So about two days ago, I started to notice that my wifi wasn't on. I was using my data in my house. I went to go turn my wifi on and off, and then I noticed I couldn't even see the networks around me, not even my own. So I waited to see what would happen. It came back by itself for about a minute, and then I was using my data again. I went and I updated my phone to the latest version, because I haven't done so in forever, and it didn't work. I reset my network settings or whatever, and that didn't work, instead it just dimmed out the wifi so I couldn't turn it on, but I waited for about and hour and it was fine. I went back into the wifi settings and the networks were back, so I tapped on mine, enterend the password, and it said 'Unable to join.' I tried it several times, I even checked if I put the password in right and I was. I also tried turning my phone off and on, and it didn't work. I really just want to throw my ohone at the wall. This is making me extremely angry because I don't know what else to do. And I am not about to contact Apple Support.

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
If the problem continues, take the device to Apple for evaluation and possible replacement. Honestly, it sounds like the Wi-Fi chip is failing.

Can't See Wifi Network At All w/ iBook..No Prob w/ Windows

The computer in question is a 12" iBook 1.33GHz model. There are several computers connected to a 3rd party router, and the iBook is the only computer not seeing the wireless network at all. Everything worked fine up until 4 days ago. No changes were made. Is the a firmware update or anything I need to do my my Airport card?
Everything has been reset with still no luck.
What else can I do?

This is actually for a friend, but she has not been around another wireless area. We can see the Airport Card in the system profiler. The firmware version is 404.2(3.90.34.0.P16).

Satellite A200 - can't use Vista after Product Recovery

Hello. I hope someone can help me with the following... This week I've had various issues with my laptop following a Vista update that System Restore did not fix, so I decided to go for a full Product Recovery (as I have a full backup of all my files).
So far I have used product recovery on my laptop in each of the 3 ways I can see (and more than once): without changing settings, changing settings and maximising the partition, changing settings and selecting the advance / expert option.
Each time I was able to complete the initialisation of windows, creating a new user account, etc. Once the desktop has been set up, I get a small window with a progress bar and when this completes I click the 'restart' button...
After restarting I get to the black screen that says Microsoft Corporation with the green progress bar, but it stays there for what feels like 'too long'. After a while I get a black screen with a cursor and then a blue screen for a crash dump.
If I use F8 and start in Safe Mode, the system stops at the CplIR.sys file, although hard disk activity seems to continue. After 10+ minutes I switch off.
If I use F8 and then select Repair Computer... this is what happens with each option
- Restore the complete windows operating system: after clicking OK nothing happens.
- Memory diagnostics: there are no problems with the memory
- DOS prompt: I have run CHKDSK and there are no problems with the hard drive
- Startup Repair: there are no errors,although the diagnostics say 'failed' when it sees there are no system restore points
Then on restarting I either get the black screen with cursor followed by the crash dump OR if I manage to sign in and get to my desktop, I get the crash dump as soon as I try to do something (like open the control panel).
Following instructions found elsewhere, I've tried this after removing the battery and then changing the power management options immediately after windows initialisation (ie. before clicking the restart button). No change.
I've even ignored the restart button! But still get a crash dump when I try to do something.
Any ideas?? I have spent (ie. wasted) so much time on this and don't understand what can be wrong after formatting the drive and re-loading windows image...

Hello
It is very interesting story. I have recovered several notebooks many times but I have never noticed something like this.
I must say that all you have done right and you think in right way. If I were you I would try exactly the same steps to get it work somehow.
I don't know which various issues you had before but I presume there issues were just software issues and not relevant for hardware functionality.
It is really hard to say what the problem can be. What you can try is obtain somewhere Microsoft Vista installations disc and install naked Vista to see if the same will happen again.
Anyway, the fact is that recovery images are tested and adapted for each notebook model and if the hardware is OK there is no reason for such behaviour.
Try with clean installation using Microsoft installations disc and let us know what happen exactly.
