Re: Satellite C660-115 Very strange Wifi problems!

I've been busy solving a wireless problem on a C660-115, still without success.
Satellite C660-115
Windows 7 - 64Bits
The case:
- Laptop is connected to the power supply: Wifi works fine, no problems
- Laptop disconnected from power supply: Wifi won't work, although there sometimes seems to be a connection with the access point/wifi router.
No internet/network communication
- Laptop connected to the power supply --> wifi works, unplugging the power supply --> after a 1/2 minute or so, no internet connection...
I tried to find a new driver, but we already use the latest version.
Then i switched off the "This computer may switch of this device to save energy" function, without succes.
Ideas anyone?

I had same problem with C660 running windows 7 losing internet access but not network connection whilst using battery power, but no problems when connected to mains power.
Solution; Change power plan to high performance. I found this sovlved the problem instantly.

System Restore problem on Satellite C660-115

Hello everyone,
The Satellite C660-115 my niece has a problem and I would like to make it serviceable for his Christmas.
Turning on the computer's voltage giving as final result the message: * Can not find the operating system will ", so I tried System Restore by first pressing the 0 key, and after many tests, changing the order of the boot and the other (with F2 or F12) ... But there was nothing.
From there, I realized that I could not go further without original recovery DVD from Toshiba. So I ordered last Saturday and got today Thursday. After as indicated by Toshiba (boot sequence beginning on CD drive), the system begins to upload (Windows is loading files ...) and then propose, on a nice table, the available languages, and choose .. .dropoff window
If, until then, everything seemed to unfold as it should, that's that clicking the "next" button to validate my choice of language an error message appears in a dialog box named RecoGUI:
ERROR:. IOCTL_GET_DISK_LENGTH _INFO \\ \ PHYSICALDRIVE0 The device is not ready.
When I press OK, then it is in French:
The hard disk # 0 is not available or incorrect RAID configuration!
I still presses OK (I do not have much choice) and then present the following window restoration that requires me to validate the language of the operating system to install ... French (Windows Win 7)
and states: The current size of restoration is to: Expert Mode
Again, I click OK and a warning box warns me that: All hard drives will be completely erased. Would you like to continue?
OK ... and cmd prompt appears that says (in short)
Checking for Drive V: V Drive not mounted ...
Ckecking for Drive C: ... C: unmounted!
ending with: ERROR Copying of Recovery Base files failed!
Press any key to continue (if I do, I find the Toshiba screen, and another cmd prompt that says so;
Waiting for ODD To Become available ...
ODD Drive D: ready.
Check for medium in Drive D; ...
Continue ...
Drvload: Successfully loaded X: \ Windows \ inf \ battery.inf.
No RAID - Normally continues ...
Installation in progress ...
Press any key to continue ... which, if I do, then placed below:
X: \ Windows \ system32>
That's where I stayed, because I always come back to the same.
Could someone be kind enough to help me solve this problem?
A big thank you in advance ...

From my point of few we should consider two possible issues.
1) faulty image on the new recovery disk
2) problem with HDD as well as the partitions
In my opinion you should check the HDD firstly.
You can run some tests, for example you could try to install the Windows system using a clean Microsoft Windows CD (image)
Windows 7 Home Premium 64bit image can be downloaded here:
http://msft-dnl.digitalrivercontent.net/msvista/pub/X15-65733/X15-65733.iso
But of course, you will not be able to activate this system without a valid serial key
So you can use this image just for testing purposes.
In case the image installation would run flawlessly, your recovery installation problem might be related to the faulty recovery media.
In such case you should try to contact the recovery media provider in order to get another, new good working media.

Strange wifi problem on a brand-new MacBook Pro

Hey there, I'm new here. Desperation has got the better of me, and I hope I can get some advice.
So, last sunday I bought a brand new 13" MacBookPro with 2.8g i7 processor and 10.7.2 OS (I can't update to 10.7.4 because System Update tells me the download has been tampered with or corrupted after I waited 2 hours for it to finish, but I'm trying a direct download from the website). Here's the exact product: http://www.amazon.com/Apple-MacBook-MD314LL-13-3-Inch-VERSION/dp/B005CWIZ4O/ref= sr_1_5?ie=UTF8&qid=1340301247&sr=8-5&keywords=macbook+pro+13
Everything is all perfect except for a strange wifi problem. Note that the wifi does not turn-on or off, it doesn't disconnect after 'sleep', it doesn't get less speed, it doesn't constantly leave a preferred connection (once I chose my home wifi it always connects to it no problem). The wifi bar is always full. What is wrong is that the internet is kinda 'glitchy'. The best metaphor I can think of is that it's like a car that has to be pushed down the road before the engine can start. Please, bear with me because this is kinda hard to explain and I'm not good at tech lingos.
One of the symptoms is browsing can get really slow and inconsistent, almost as if the wifi gets turned off in the middle of browsing. For example: if I look something up on Google and then open 5 new tabs, probably only 2 or 3 of those tabs will eventually load while the other two will not get past the long 'http:.......google.....etc etc' address and will eventually show one of those 'error loading page because there's no Internet connection' notice. This happens a lot. Sometimes I have to refresh/retry loading a page a couple of times before it finally loads, then usually everything will get back to normal and I will be able to open multiple tabs with no problem, but in a couple of minutes I would try to open another site and the problem will start again.
So I tried to see how it does with downloading using iGetter. Fortunately I also have a Macbook (white-plastic casing one) and my brother has an old 2006 MacbookPro so I can compare. With those two older Apples iGetter starts receiving data in less than 8 seconds after I click Start, while my brand-new Macbook Pro can take up to 15-20 seconds, sometimes it doesn't even start at all and I have to re-click the start button. But once the download actually starts (on my new MacBook Pro), it downloads like normal, it doesn't stop and the speed is also as good as I can get. Strange huh? Hence, like a car that has to be pushed before the engine starts.
I also tried 'speed testing' from a website with all 3 laptops. On my old MacBook and my brother's MacBook pro, once I click 'begin test' it takes only a couple of seconds of 'ping' before the download/upload speed measurements start, but with my new MacBook Pro (just like with iGetter) it takes up to almost a minute before the measurements start, sometimes it won't start at all and I have to re-start the test.
Well, thanks for reading. And hope you can help me shed some light into this. Because it is really preventing me from really enjoying my new MacBook Pro. And if this is most likely a hardware problem, I'd better get back to the store and try to get it replace or something while it's only been 5 days. *cheers*

Hey guys.. Thanks for the replies. Unfortunately, I bought the MacBook in Indonesia where there are no such thing as an AppleCare. The only option is to leave the Apple product to one of the 'Authorized Apple care centre' and have whoever do whatever to it without guarantee of success. As for returning it and getting a brand new one, I also don't know if there is such a deal here, but that's actually a good idea, will try to go to the store tomorrow. Although, I'm worried that the problem might be with OSX Lion or something and getting a new one won't help.
mark75090, I've tried resetting the router when I first noticed te problem, didn't work though. I've checked my new MacBook's wi-fi (option+click wifi bar) and it says 'PHY Mode: 802.11g', so does my MacBook and the old MacBook Pro. I don't know what those mean though, and I don't know whether or not my router is an N., can you tell me more please.. I have tried with the other two turned off, and only the new MacBook using the wi-fi but the problem persists. I have also tried connecting directly to the router, but as I described, the problem is too subtle for me to notice the difference.
Also, if I create a brand new Wi-Fi connection in network preferences and connect to my router through the new Wi-Fi profile, the problem seems to be gone for an hour or so, then it always comes back though. I have also just finally installed 10.7.4, but it doesn't help either.

Very Strange Internet Problems

I own a MacBook Pro 15.4 Inch that I purchased about a year and a half ago. I recently upgraded to Leopard and have all the latest updates. I am from the US, and when I am home my internet works fine. However, I am on travel to Seoul, South Korea right now and am having a very strange internet problem.
As far as I can tell, the URLs that I type in to my browser are, sparodially, not translated correctly into the webpages that they are supposed to represent. This problem is probably effective 75% of the time, and the rest of the time my internet works roughly correctly. For instance, when I enter http://www.google.com, instead of being taken to the Google homepage, I am taking to the homepage of Jammin Beats DJ Service, an obscure website about a company in northern Pennsylvania. The actual URL of this website is http://www.jamminbeats.com, but when my internet is malfunctioning, 'jamminbeats' is for all intensive purposes replaced by 'google' (that is, it applies not only to the main page, but to sub pages, so "http://www.google.com/weddings" takes you to "http://www.jamminbeats.com/weddings" and etc). For most other webpages, one of two things happens. Either I am taken to the correct page but it is displayed without any images or frames (just the html text and links), or I am taken to a blank page with the header "Under Construction", which I assume is the default for a page that doesn't exist. This is why it seems as though the URLs are simply being interpretted erroneously.
This problem occurs when connecting both to the wireless and the wired internet at my hotel, and it occurs on both Safari and Firefox, so it is not a connection-specific or browser-specific problem. It may be a problem with the hotel's internet, and as of yet I have not had a chance to test the computer at another location. However, a colleague using an IBM computer has had no problems, and I am currently on a Samsung machine in the business center of the hotel and it is working correctly as well. I have searched extensively online for a similar problem but have come up empty handed, and more than anything, I am confused about what might be causing this problem. The strangest thing is that a fraction of the time, the internet functions normally, but it is usually roughly 15 minutes out of every hour, and eventually I am inevitably taken back to Jammin Beats.
I am a computer science graduate but I still have no idea what would cause this problem. At first I thought it might be a hacker, but if it is, he or she has been at it consistently for 3 days now, and only seems to be targeting my computer. Any ideas or solutions would be greatly appreciated, as I have been forced to resort to the hotel's business center for checking email, doing work, etc. Thanks in advance.

I did consider that, as I was in Beijing last week and there are a number of censored sites. However, in Korea I have had problems with very basic sites like facebook, wall street journal, google, yahoo, Korean google, my hotel's webpage, etc. Further, I have successfully gotten all of these sites to load seemingly at random, and can access them without problems on other computers. The only disconnect seems to be between my MBP and the internet, not between Korean internet and the web. I have toyed around with the network settings, and although sometimes after switching from "Automatic" to a fixed connection I get some sites to work, it usually only lasts a short time and eventually the same sites stop working. I reset my cache regularly to make sure I'm not getting sent to cached sites, but this also doesn't help. Further, my Apple Mail, Skype and AIM accounts jump between being connected and disconnected randomly as well. Again, this is isolated to my own computer, which is why I'm so confused.

Have never heard of that problem before so can only give you an idea of some things to check.
Check in the Homehub management that it is not set to block access to the mobile devices. If you did a factory reset of the hub then it should have cleared any settings but it might be worth checking.
Have you checked that they are connecting to your Homehub and not to BTWifi which would require further log on to get internet access.
What exactly is happening with the devices when you try to connect to the internet. Is it all things to do with the internet or can you connect by 3g?
Have you tried to connect using another router such as at a friends house?

Very strange power problem...

Hey guys (and girls ofcourse),
I'm having a very strange power problem with my late 2007 2.2Ghz santa rosa macbook.
Can you guys help me determine what the problem could be?
Here's what happened prior, when the macbook was still working. I got home from work, plugged my adapter into the wall, and it started charging. I left it on the table, and when I came back from the diner table I continued working, but suddenly noticed my macbook wasn't charging anymore. (the orange/green led wasn't lighting up but i was able to work on battery power)
I thought it was the poweradapter, so I went to the apple store the next day to lend one to test it. That didn't work, so it's not the adapter.
So then I started thinking it must be the magnetic DC connector. So I ordered that from the guys at ifixit, (since it's out of warranty) but I replaced it and it's not working.
I don't think it's the logic board, because I was able to continue working until I ran out of battery power. And I also don't think it's the battery connector, because if i'm not mistaking, the macbook can run without battery as well, but mine can't anymore.
Now I can't get any life out of my mac anymore...
Might there be something I overlooked?
Any suggestions are definately welcome!
Thanks a lot.
Timo from Belgium.

Hi Timo,
I think i have the same problem, my mac is not working without battery in it. and it wont charge it.
i wrote a post here http://discussions.apple.com/thread.jspa?threadID=2105648&tstart=0
let me know if you have fixed the problem
thanks

Very Strange Focus problem

I've encountered a very strange focus problem that I hope someone can help me
with. In my frame, I have a toolbar and some JTextFields. When I press one of
the toolbar buttons, I do whatever and at the very end I use requestFocusInWindow()
to set the focus to one of the JTextFields. Now here's the strange part. If I don't
touch the keyboard or the mouse, I can see the caret in the JTextField as expected.
As soon as I move the mouse or touch any key, the focus changes to the next
toolbar button. Makes no sense to me. By the way, I'm running 1.4 on Windows NT.

Create a new class ToolbarButton extends JButton where you have the following method:
     * Identifies whether or not this component can receive the focus.
     * A disabled button, for example, would return false.
     * @return true if this component can receive the focus
    public boolean isFocusTraversable() {
       return false;
    }This prevents the buttons from getting keyboard focus, this makes only sense for toolbar buttons.
Cheers,
Taoufik

Very strange MRP Problem

HI ALL
I am having a very strange mrp problem and that is
I created a material with all mrp1and mrp2 requirement,created the info record and source list for that material.I created a reservation for that material which in turn created the deficiency when I did the MD04.I run the MD03,as per re-order point and fix lot size two Preqs created( vendor was not shown in the Preqs even though I established the source list for the material?).I change these Preqs into PurOrds and did the Gr.Every thing fine till here all changes happened in material requirement list(MD04).Now I did one more reservation and created the deficiency again and run MD03 again with a message that mrp done but this time when I went back and checked MD04, there is no Preqs shown and deficiency remained same as was before. I did the same exercise on several material and every time I am having the same problem as the 2nd time the Preqs don't show in MD04. Please help me as I check upto my knowledge but unable to resolve this one.

what is the control parameter of the MRP run that you select.

Very Strange Bluetooth Problem

Hi There
My mac seems to have developed a very strange bluetooth problem. When i try to connect my mighty mouse, it 'connects' then a couple seconds later disconnects, then connects and disconnects etc. during the time that it is apparently connected, the LED on the bottom of the mouse keeps flashing in the way it does when it's searching for a connection, which tells me it ain't connected at all.
Thinking this was just a mighty mouse problem i try connect my iPhone, same problem. This time I do it with the bluetooth preferences open i notice that the status of the iPhone connection has gone funny (like it has not connected on top of the word connected in the status, one atop the other) this weirdness happens irrespective of what you connect, and only to the iPhone status, even if it's bluetooth is off.
This weird status thing has happened before, when i was messing about with bluetooth tethering on my iPhone. So, naturally, i assume the iPhone's buggered up the system somehow. I remove it from the list of paired things and try the mouse again, no luck. I try to re add the mouse, but the pairing process doesn't complete itself before the mouse drops signal again. I can't re-pair my iPhone either for the same reason.
how can i fix this?
Cheers, Joe

Hey there,
Navigate to HD > Users > Your Account > Library > Preferences.
Locate, and move to the Trash, this file com.apple.Bluetooth.plist.
If still no luck, try zapping the PRAM to see if that helps. Instructions on how to do that can be found [HERE|http://support.apple.com/kb/HT1379].

Strange wifi problem, laptops work fine, phones do...

we have a homehub3 and have just started having a very strange problem
The laptops in the house all connect and work fine over the wifi as normal, but as from yesterday our, ipad, 2 iphones and a samsung galaxy all connect to the wifi, but cant actually use the internet. we've tried restarting everything, forgetting the wireless connections on the phones and reconnecting but nothing appears to work. Any suggestions?

Hi dude
I would like to add some notice to msconfig:
msconfig should only be done by an advanced user who know what he is doing.
If the incorrect a service or statrup is stopped this may have sever consciences for the OS.
If you dont know exactly what single process is responsible for, then dont touch this.
But Ive got a tip for you;
You can also use google search function in order to get more details about the single processes.
I found very useful and interesting page about msconfig:
http://netsquirrel.com/msconfig/msconfig_win7.html
Now back to BIOS and windows booting time;
Are you sure that SATA settings in BIOS are set to AHCI?
Be sure that this is set to AHCI instead of compatible. If the option would be set to compatible then the HDD would operate much slower and this could be also a explanation for your issue.

Ipod strange Wifi Problem!

Hi Guys, I have a very strange problem with my Ipod: If i try to connect to Internet via Wifi the Ipod simply tells me, that he is unable to join Network xxxxxxxxxx. If i click the Network more often it sometimes connects, but only for like 2 minutes until it disconnects again without error message. I checked password and I'm only like 3 meters away from my router. I restarted my Ipod aswell as my Router, tried to change language to english from my native language. My Router does not filter Mac Adresses. My Ipod is on version 5.0.1 and always tells me that connection range is very good, but it simply is not able to join. Now about the strange things: I do have 2 Ipod's and both had a good working internet connection until last week. From then on both Ipods had this problem. And: IF I go to different spots in my house, I can join the Wifi Network, but it disconnects when I go away from them again, even though my ipod tells me that signal strength is always good. The Spots with working internet seem to be unaffected by distance to my router.
Thanks for your help.

as your ipod is 5.0.1 is still slow, because there is already 5.0.6, you can upgrade the ituneswith my did the same, but already upgraded. your iPod will be updated with aaltomaticamente tempo.e as you use at work you can block or the wi-fi with this problem.

Need your help with very strange Oracle problem..

hello,
At our office we have an oracle 10g database (don't have exact version on hand) installation that stores data for many of our applications. We are having a very strange, intermittent issue that is causing us lots of headaches lately.
The problem is, the database will be running fine, humming along, with clients connected to it, from different hosts, different networks, and using different technologies (PERL DBI::DBD, OJDBC, etc). Every so often (at intermittent intervals, no real patterns we can discern), it seems as though the database will just hang and not respond to requests for a few seconds. Outages have ranged from 1,2,3 seconds to sometimes 20,30,40 seconds (very rarely longer than 5-10 seconds though).
Over the last few weeks, we've done lots of work to try and rule the network out of the equation. Today, a java client i wrote that was running locally on the database host, connected via OJDBC timed out (my timeout was set to 5 seconds) running a simple query ("select sysdate from dual") at the same time as all our other remote clients.
I'm really not sure where else to look at this point. Our DBA department says they see no errors in the database, no indication of problems anywhere. We've ruled out our backend applications and the network at this point. The java test client i wrote was running from about 5 different clients, dispersed through many different networks. They all timed out at the same time as other network clients that run via perl's dbi/dbd framework.
Can anyone suggest what would be a possible cause for this? How could it be possible that network clients issuing "select sysdate from dual" would hang for over 5 seconds?
Thanks in advance for any suggestions you can offer.

I am hoping you are not in a situation where your DBA said there's nothing wrong with database, your network admin said networking issue ruled out, your system admin said OS is normal. Yet, you as end user suffer and end up trying to figure out the issue by yourself while you didn't have expertise in any of these fields.That's basically the situation we were in for a few months here. It was, to say the least, extremely frustrating. Since we wrote the applications that were suffering the most due to this db/hardware issue, naturally, we felt "responsible" for taking the ownership to track down and fix the issue (after some perseverance ,we were finally able to narrow this problem down to a database storage issue).
After exhausting every other dba theory about DBI/JDBC/Firewalls/Networks/etc, we simply just failed over our database to some standby hardware that had some directly attached storage (as opposed to a SAN configuration like our primary db instance runs off of), and the problem has basically disappeared at this point. It's been about two weeks now. Whereas we normally see a handful of episodes a day, now we see none.
Our system administrators are looking into our SAN now and working to optimize its performance.
Hopefully this will put this mystery to bed. It's been a long year+ chasing this problem down and I'm glad to see it licked finally. Thank you all for your input. I've learned quite a bit about Oracle in the process and I sincerely hope our DBA team here has learned something valuable from this exercise too.

Very strange SQL problem

Hellou everybody,
I have very strange problem and I don't understand WHY.
when i run this query:
SELECT regexp_instr(nvl(trim('LDAPexport_20150429'), '^.*$'),'^\^[0-9]{2,2}_[A-9]{1,1}[A-9]{1,4}/') FROM dual; --ERROR
I always getting this error: ORA-12728 - invalid range in regular expression
but when I run this:
SELECT regexp_instr(nvl(TRIM('LDAPexport_20150429'), '^.*$'), '^\^[0-9]{2,2}_[A-Z0-9]{1,1}[A-Z0-9]{1,4}/') FROM dual -IT WORKS
My client version is: 11.2.0.1.0
DB version:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
"CORE 11.2.0.3.0 Production"
TNS for Linux: Version 11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 - Production
Please can somebody tell me what is the problem? Because I found this issue in production code and my collegues can run it.
Thank YOU

and i have created one transient field Static_cr_limit where i set default value using SQL option- which comes from another table. Can you tell us the expression you used to default this field. Also a little more details or a similified use case as ADF7 mentioned would help.

Strange Wifi problem

Hello all,
Im aware that most of you are not waiting for yet another wifi problem and I always try to solve them myself, but this time Im not able to do so. The problem is as follows. On my university, I can get a good wifi connection for approximately 30 minutes, (IP and data) but then the connection refuses to transmit any more data.
I've tried multiple wifi cards (Centrino 1030, Ralink RT5370) and dongles, they all give the same problem so I assume thats not the cause of the problem. Also in Windows the connection is kept alive continuously, so thats another confirmation the hardware is working fine.
My guess is that there is a problem in the configuration of my wifi connection on Arch. Two possibilities pop up to me.
1. There is some kind of threshold (time or amount of data), that blocks the connection after a while
2. The wifi connection needs to be refreshed each particular amount of time but Arch (dhclient / dhcpd) is not able to do so
My question is, do you have any suggestions how I could test for both theories or even better solve the problem. Its very annoying when Im working the internet connection stops working every 20 minutes or so. Thanks!

This seems the most likely to me - as this is how it works. But knowing which one of those tools you use would be helpful. When you connect dhcpcd and/or dhclient gets a lease from the DHCP server on the university network. These leases have a fixed lifespan (30-minutes sounds reasonable). When they are about to expire dhcpcd/dhclient should try to renew the lease. Generally, though, the DHCP server (as far as I understand it) will trigger the renewal a bit before the expiration time. Based on my experience at a few universities, however, university networks (at least in the US) often have malfunctioning dhcp servers which limp along mostly functional on most days. I don't know the workings well enough to understand why dhcpcd or dhclient would fail to renew the lease when they are supposed to - even in the absence of the early-renewal trigger from the server, but anecdotally, I see this happen occasionally as well.
And this is complete speculation but I wonder if it is possible for the DHCP server to send out over-estimated lifespans for the lease which then prevents dhcpcd from renewing at the appropriate time. I don't know these systems well enough to know if this idea makes any sense - but it would certainly fit with my experiences.
