Hi

I have installed 12.04 LTS on my toshib z835 and I had used it for around 3 weeks without any problem however yesterday suddenly my internet has stopped working.

Only change was my battery died while it was connected. How do I figure out what is wrong ?
Can any body help me here?

Wired and wireless both are not working and I am able to ping to my wireless router as well my desktop connected to same wireless router via its IP

done all this booted also couple of times. I wanted to verify that nothing has gone wrong from the hardware side so booted with from USB ( 12.04.01) and checked that internet is working so hardware issues is ruled out.
Is there anyway to check if some part of HDD is corrupted ?

I have seen some warning that some sector is bad while shut down or boot up sometime ago.

Please help I need to submit something by end of next week to client and without this wireless working I will die.

Check the smart data status under Disk Utility program (use Unity to find it), it will tell you the health of the HDD and if any bad sector. Post back the result here !

you have a bad drive that can not a section you might want to get a new drive in a portible case. that way you could install Ubuntu then put the old drive in the case and copy all the data over.
backup-ups or working copy of complete disks is a must have on any computer
with any operating system:rolleyes:

Hi

I have all the critical data backed up. And as this is Toshiba ultrabook so I am not sure if I can buy a SSD myself and replace it.

I am just curious that if there are bad sectors how come only this internet function is getting affected ( this is the 2nd install of the Ubuntu 12.04 and and both the times I have faced this same internet issue)

also is there any way to confirm this? And what about other people ?

Nikunder can you run the same thing over your machine ?

Probably because of the cache, which is written/read over many times when you surf (browser load data from web into the cache, then read the disk to render the page).

The machine is under warranty ? Will they replace the SSD do you have any idea?

operating files are normally do not get moved and end being located in the same location during install so same drive and same operating systen the same file will end up close or in the same location. in your case it is in a area that cannot be read but can be written to. the repair is the same a bad drive will always give intermitant operation and usually gets worse fast.

I gave it to toshiba service centre and (as expected ) they said that they don't support ubuntu. They re installed windows 7 and now with chkdsk there are no bad drives

bad spots in a drives can come and or go. while I would hate to trust a drive that failed once already. As far warr goes they will not want to replace anything unless they have to. I seldom use a warr for that reason
but we all hate to throw parts and money at new computer too. try it and hope it stays running. and keep a good back up just in case. :)

Yeah I guess that is true. However it is SSD so I have slightly high hopes and I keep all data backup always

thanks for your help.
