Ideapad U330 causes network crash

Hey everyone,
I have a friends ideapad that is having a wierd network issue. Whenever I try to connect it to my wireless network it causes the whole network to loose its connection. I have tried it on three different routers and it has the same effect:
Network is working fine with other computers connected and able to browse the network. I boot the ideapad and turn on wireless. It sees the wireless and asks for WEP key and connects. As soon as the ideapad connects then all other computers on the network can no longer view websites.
I have also disabled the wireless card and tried to hard wire into router with same result. Network card drivers apear up to date. I have only ever been able to connect if I remove the router and plug directly into the cable modem.
Can anyone give any ideas for a solution?
Thanks,
Eric

IPod touch 4G causes home router/network crash

Hi. I have an iPod touch 4G, version 4.3.4 (8K2). Everything was working fine.
-One morning I wake up and my home internet connection is down (LAN/WLAN), I cannot even access my router web interface. I restart (power down and up) my modem/wifi router (2-in-1) and everything works again for a while before going down again. This keeps happening - sometimes lasts 20mins, sometimes a few hours. I call ISP tech support (check the line, factory reset router), read router forums etc. etc. Nothing solves it.
-In the mean time, my 4G has a lot of trouble connecting to the home network. Takes a long time to get DHCP and has the wrong (auto) DNS assigned, just doesn't "instant connect" like it used to. Even when I assign a static IP and manually enter DNS, Router etc. it has a very hard time. I have tried "Forgetting Network", resetting Network Setting on iPod, restarting the iPod and rediscovering the network doesn't help.
-Every other iOS (iPad, MacBook Air) and Windows or Android wifi device connects to the home network fine.
-Because of this I unconciously leave my iPod switched off - network starts to behave. One morning, I switch my iPod back on and try to connect - instantly my home network goes down. All the other wifi enabled devices simultaneously drop connections and the wifi SSID is gone. I cannot connect to router web interface (via LAN) until I restart the router.
-So I seem to have isolated it to the iPod and investigate more. I see that when I try to connect with the iPod, the DHCP takes forever and when it is "trying" to get assigned, the network is not accessible to any device. Most of the time the network crashes as usual. A couple of times, after a while the network comes back up and the iPod connects but then sure enough it crashes again soon.
I have tried everything short of resetting the entire iPod and buying a new router. Has anyone else had this problem? The only reference I have found in these support forums is here and there doesn't seem to be much noise on the topic and it's now quite old.
https://discussions.apple.com/message/10853567#10853567
Any help appreciated.

Yes. I tried this the first day when I thought it was a line problem and contacted my ISP. They suggested I try this and we went over it on the phone. The internet did come back on and I naiively thought it was fixed but after a while it went down again. At that time I did not know that it was my ipod that was causing the problem. That was only after looking back on the whole thing that I realized that.
Actually whilst googling the problem I found a youtube video of the exact same thing happening to someone but there were no solutions or comments on why this is happening.

OVM 3 Generic Storage Plugin. Acess Group configuration causes server crash

Our iSCSI management is currently entirely done manually at the servers console, because we still don't have a SAN Equallogic storage plugin.
At OVM Manager interface, what we thought being just useless in our case (SAN Access Group), is the actual iSCSI connection (and disconnection..) management for servers.
Following the upgrade to 3.2.1, setting up the SAN did nothing more than what we do manually. But undoing part of it caused the crash.
All over OVM Manager, any operation/setup that could impact running VMs is denied... Except there, at the real root of everything.
Removing a iSCSI initiator from that panel disconnects abruptly the iSCSI disk, !!!! without warning !!!!.
Then, after the 60s timetout, the physical server reboots.
It is still not clear if we get a benefice to setup that "Access Group" of the SAN or not. At least, once setup, we know that we'd better keep it...

Updating OVM 3 host to use "brbond0" vs "xend" managed bridge to allow direct hosting of OVM Manager VM.

Vodaphone dongle causes panic crash. Help please?

It is essential for me to use a Vodaphone dongle for certain work purposes. After installing Snow Leopard, dongle caused panic crash in my MacBook Pro. 4 panic crashes and reports to Apple later ... alert message appears as follows.
" System/Library/Extensions/USBExpressCard can't wake_Huawei.kext"
Check out support and hit on Welcome Wake Up issues. More like Unwelcome! Is this the problem?
Have reinstalled Leopard since this dongle is the only way to connect at work.
Any ideas?

Hi everyone
Vodafone really have not excelled here but today tracked down a solution using the GlobeTrotter application to intall the right modem driver (not sure but I think this was the problem causing kernel panics)
Here is how to do it...
1. Make sure you delete any extension from the System/Library/Extensions folder containing the word "Huawei" in the file name
2. Restart
3. Download latest version of Vodafone Mobile Connect (which by itself will still cause kernel panic if you install and then plug dongle in and install.
4. Download latest version of GlobeTrotter Connect (http://support.option.com/att/index.php?title=GT%20Connect%20for%20Mac%2010.4.11 ,%2010.5.x%20and%2010.6.x%20and%20Manual&action=module20/index)
and install it.
If asked to confirm new network preferences do so - this I think installs the updated modem driver which I think was the source of the kernel panic previously.
5. Then insert USB modem - should not cause kernel panic!
6. Then run the Vodafone Mobile Connect software and press Activate
It works and does not crash!!
Good luck!

Why does my airport extreme network crash once each evening around 6 P.M.?

Like clockwork, every darned day, my network crashes with no known cause. I'm with Comcast as my ISP but they seem to have no clue - or won't admit it if they do 1 about my crashes. Every service tech they send out has a different possible remedy, like the likelihood of a switch being activated nearby that causes my network to crash so routinely.
Anyone have any experience like this before?

One of the problems with Air Radar and other utilities like this is that it will not display the signals of cordless phones, security systems and even other "closed" networks around you.
As you know, a "closed" network will not display the name of the wireless signal when you scan looking for networks.
This is a popular feature with many users and you can probably safely bet that there are at least 3-4 other networks around you that Air Radar cannot "see".
Other wireless routers are continuously looking for a good channel to use, so while you may have a "good" channel for a time, in a crowded area, some other router will likely jump on the same channels.
Cordless phones change channels continuously so even if you could "see" their signals...(and you can't with Air Radar)....they are tough to avoid.
Did you try different locations with your AirPort Extreme?
Can something from within my iMac be causing this calamity of networking failure?
Nothing that I know of.
Most wireless networks operate on the 2.4 GHz band. A newer Apple router and also routers from other brands will operate on both the 2.4 GHz and 5 GHz band. There are very few networks using 5 GHz so that might be something to think about. The problem here is that your G4 will likely not work on this frequency.
The other thing to think about is having a professional IT person come out to your house to run some scans using pro equipment. I can't say that this will help, but if Air Radar shows 4-5 other signals, you can bet that the pro equipment will probably display over 20 possible sources of interference in your area.

I have files that freeze my programs whenever I try to open ANY file. Is there a way to find the exact files causing the crash?

I have files that are freezing my programs (adobe; after effect and photoshop, as well as maxon cinema 4d). Whenever I try to import ANY file from within the program it doen't even let me select the file I need before freezing. I have moved all files off my desktop and into my dropbox, and it now allows me to import files/search for files on the desktop but NOT dropbox, once I go to dropbox it freezes again. I am assuming there are files within dropbox now that are crashing my programs. The problem is I have a lot of files in there and would like to remove the corrupt ones so that I can use my programs without freezing. Is there a way to find the exact files causing the crash?
This has happened a couple of times and each time I have to move all my files off my desktop, so there must be a type of file doing this, I just don't know what files they are.

ANY help would be greatly appreciated! It is making it really hard to get work done. THANKS!

This error sounds to me like you have/had BootCamp Windows installed and then removed, posible ?
If so (and even if not so), try restating your MBA while holding down the alt/option-key until you get to the Boot Selection Screen.
Choose to boot OSX.
Once in OSX go to System Preferences then Startup Volume and set your OSX to be the default.
Hope it helps

Using Disk Warrior on external drive causes MacBook crash

I work on MacBook System 10.6.7, I back up to LaCie external drive, which I partitioned so that one partition is only for backup, the other is bootable. On this partition I have a clone of Disk Warrior (4.1), to use on the MacBook .
Today I ran DW from the MacBook on the external drive for the first time, because lately it happens that the backup partition does not always appear in the finder (still performs back up though). I applied it first to the boot-partition, and it told me there were some problems. When it got to replacing the directory, the computer crashed mid way.
I performed Disk Verify on that partition through Disk Utility, and it said that it needed repair, and then that it did repair it. Checked other partition, no problem.
Tried again to rebuild directory for the external drive, and both partitions caused the MacBook to crash. I then booted from the external drive to see if it works, and ran DW on the MacBook, and had no problem there.
Anybody can tell me if it is the MacBook that caused the crash, or if the problem is with the external, and if there is anything else I can try to sort it out?
thanks,

Use of discrete graphics causes hard crash - (MacBook Pro 2010 with ML 10.8.2/3)

I have a client with a Mid-2010 MacBook Pro. He was having crashes with Lion so I upgraded him to Mountain Lion 10.8.2. The crashes did not go away.
I troubleshooted and with the help of gfxCardStatus noticed that every time his machine went to use the discrete graphcis he got the gray hard crash screen and system had to restart. Back then I tried a beta of 10.8.3 and it didn't help.
I noticed that if I created another user account (profile) it would not crash when the discrete graphics card was called upon.
So, I re-installed the OS (to 10.8.2), created a new profile and manually migrated pictures, documents, keychain, mail, movies, music and re-installed the relevant Applications. Everything was working fine and my client went on a trip to Europe and soon the crashes began again. Then he upgraded to 10.8.3 and the crashes got even more frequent (it seems 10.8.3 puts more applications on the discrete graphics list so it switches even more).
I am wondering what could have caused the crashes to begin. It was before he upgraded to 10.8.3. Some application or something he was using must have changed a setting or corrupted something to cause the crashing to begin. I haven't done this yet, but I'm sure if I create another user account it won't crash on it.
Any ideas where to turn my attention to see what is causing the shift from his working user account to a crash-causing one?
He has iLife, Office 2011, Final Cut Pro X, iPhoto Library Manager, VLC, Audacity, DropBox, FileMaker Pro 11, Flip4Mac Player, Fuze, GotoAssist, Handbrake, Skype, iSkySoft DVD Creator, iSkySoft Video Convertor, Onyx and Skype.
I know there are *MANY* others having problems with the automatic graphics card switching and it seems some are having more problems when gfxCardStatus is installed?

Take a copy of the article with you when you go for service. They need to run a SPECIAL diagnostic to decide whether you have this problem. Do not leave until they run the special diagnostic. The "overnight run" does not detect this problem.
If they confirm you have the problem, they will replace the graphics chip, which is part of the motherboard. be prepared to hand over your Mac for depot repair. (Your backups must be up-to-date).

Is there a way to track down the cause of crashes in SAFARI?

Not long ago I was able to eliminate one type of crash I had been having in SAFARI by following a suggestion made in this forum. Those crashes, however, were of the type that generated a 'crash report.' So they left a kind of 'paper trail' as to what was causing them.
More recently I have been having frequent crashes that don't result in such reports. These crashes occur apparently randomly when I mouseclick on a link. The spinning beach ball appears on-screen and never leaves.
Is there a way to find out exactly what is causing these crashes?
Thanks.

Hello Michael:
I have not yet seen a
good approach to using that information (short of
deleting the account).
better search some yourself Barry <G>
if something runs fine in another account - one can isolate the cause to one of the plist files in the main acct Home/Library/Preferences/ or possibly an add-on in Home/Library/Internet Pug-Ins or ...Input Managers for example.
If there is the same problem in the new acct - you can discount anything with the main acct user library - plists,caches,plugins,input managers, the whole lot.
A useful tool is Console - found in Applications/Utilities/ keep it running while the 'problem' in question crops up & see if any messages pop up in either the system log or console log. Sometimes these will point straight at the problem area, other times no help at all.

Sticky Notes in a pdf file cause ie7 crashed.

This is a very interesting bug.
System version: Windows XP with SP3
Adobe Reader Version: 9
IE version: IE 7
Files needed for testing:
a pdf file (note.pdf) with Sticky Note displayed.
a html file (note.html) which has a url link to note.pdf
Action which causes the crash:
1.       Open note.html in a new IE window
2.       Click the link to open the note.pdf in a new window or a new tab, then close it
3.       Click AGAIN the link to open the note.pdf in a new window or a new tab, then close it
Then you could see the error window popup, the ie7 browser crashed. This has been tested in 3 PCs.
Check the Error Event, it said:

KB3038314 causing IE crash

hey all,
hopefully i have the right forum for this question.
the IE cumulative update for the past few months has been causing IE to crash on one of our internal websites.
the March update (3032359) has a documented issue with table-based websites (which our internal site is); this issue isn't documented for the April update (3038314), however it's still crashing IE on this website.
if i understand the cumulative updates correctly, they're a roll up of individual IE updates. from what i can see, there's no way to uninstall these updates one by one.
my current theory is there's an offending update within the cumulative that's causing the crashing issue, but not sure how to isolate the offending update.
make sense? any help is appreciated.
thanks!

Hi Matt,
>>if i understand the cumulative updates correctly, they're a roll up of individual IE updates. from what i can see, there's no way to uninstall these updates one by one.
Yes, your understanding is correct. Please try to remove this update.
If this issue is very urgent, you may contact Microsoft Customer Service and Support (CSS) via telephone so that a dedicated Support Professional can assist with your request.
To obtain the phone numbers for specific technology request please take a look at the web site listed below:
http://support.microsoft.com/default.aspx?scid=fh;EN-US;OfferProPhone#faq607
Hope the issue will be resolved soon.
Steven Lee Please remember to mark the replies as answers if they help and unmark them if they provide no help. If you have feedback for TechNet Support, contact [email protected]
thanks for the response; is there a way to uninstall individual updates that are included in the cumulative?
it's likely that one of these updates is causing our issue, and until we determine the offending update, we'll likely continue to encounter this issue going forward with the cumulative updates.
i can contact Microsoft support, but if there's a way for me to uninstall each update manually, i can easily take the time to troubleshoot this on my own.
any ideas?
thanks!

Problem touch screen IdeaPad U330

Hi!
I know this problem might be posted before, but I couldn't find it.. So I'm trying it this way.
Since a few weeks my Lenovo IdeaPad u330 has a problem with the touch screen. When I start my laptop, it works perfectly, but after a few minutes - or maybe an hour (it's quite random actually) the touch screen stops functioning, and I can't use it at all. I've used my laptop for over 10 months now, and the problem only started occuring a month ago, I think.
I think it might have something to do with the fact that my apps stopped working and that I had to 'restore the system'.
For the record, I'm still using Windows 8..
Anyone's got a clue?
Thanks in advance!

We've just started having a problem with the touch screen. The screen becomes unresponsive and while the trackpad works the cursor flickers so you can only see it while it's moving. After a bit of playing with it I realised that it was registering some presses at the bottom of the screen- you could see the touch feedback circles. If I moved the screen a little, holding it at the top, more or fewer touches registered, so it looks as if the screen housing is putting pressure on the touch screen. If you hold the screen just right then no touches register and it goes back to normal.
I'm just getting ready to return it. Probably try to get a refund because it looks like a design fault to me. Shame because it was a great laptop (despite windows 8)

Hi,
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
If after reboot that doesn't help...
Open Console in Applications>Utilities & see if there are any clues or repeating messages when this happens.

Emptying iPhoto trash causes iP crash

and it rhymes!
Using latest version of iPhoto, I was deleting a number of photos a week ago or so when iPhoto crashed. When I re-opened iP after a restart, everything seemed okay, so I proceeded to add more photos to the trash folder and tried again. It crashed again. It's obviously doing something because all of the thumbnails for the photos in the trash are gone (nice little box with dotted line) and if I try to view a full size image, it gives me a big box with a small question mark in the middle.
The left info window shows the file size, date, etc of each photo still so it seems to me that the photo is still there, but not displaying, not to mention that I can't delete the 1 GB or so of images I have in there. I've tried doing everything in the ctrl-option window but to no avail.
Is there any way I can get rid of these photos? Thanks!

I can't figure out how to delete, so this has been solved. It was just one file from another persons camera that was causing the crashes. Removed that, deleted all the rest and then deleted the one photo by itself. MAGIC!
