I guess you were right. My problems with NP900X4C are not over. After Samsung service replaced the dreadful Centrino Advanced-N 6235, there ware no problems simple surfing Internet (using 802.11n). Streaming (for example youtube) was much better than before. I was so sure the problem has gone.
But yesterday It disconnected twice. Today I used the ultrabook with router which caused the least trouble before, but there was again a single connection dropout (with wi-fi icon with * as usually). I managed to test large file transfer. It causes the wi-fi to disconnect (yellow exclamation mark). Then again I had to manually turn the wi-fi off and on.
I'll give it chance tomorrow again. If it persists I'll give it back for service again. But then what? I see that Samsung keeps selling NP900X4C-AO2PL and newer NP900X4C-A03PL, but both have the same Intel® Centrino® Advanced-N 6235. Don't they know the problem or is it solved?
An option would be replace Centrino and lose guarantee - risky. Is the wi-fi card removable or soldered in ultrabooks?
My opinion is manufacturers should let customers chose: money back or replacing wi-fi card with something else than this rubbish.
Do you know any other good ultrabook suitable for working (which means - with at least 15 inches screen) without hopeless Centrino Advanced-N 6235?
...and I have other problem too, after my Notebook wakes from sleep-mode, no Wifi and must wait 50-60 sec for reconnection. On my other Notebook (Broadcom wifi) it takes 1-2 sec.
(Unchecked "Allow the computer to turn off this device to save power" under Power Management, Power Plan "Maximum Performance" and 2 MS Virtual Adapters are denied)
I hope this doesn't throw everyone for a loop but, just like you all, I'm experiencing the same problem. Oddly enough, my wife's laptop (which is equipped with an Advanced-N 6250) has never experienced any of these issues in the 3 years we've owned it (Dell XPS 1645). Her and I both are using the latest wireless adapter drivers from Intel. The difference is she is using the Advanced-N 6250 on a Windows 7 64bit platform compared to my Advanced-N 6235 (MSI GT70 Laptop) on a Windows 8 64bit platform. Same location of the house (different times of course)
My laptop originally came with a Wireless-N 2200. After experiencing these exact results, I opted to upgrade to the 6235 hoping that would fix the problem. No dice.
I just wanted to share. I'm thinking I'll try and disable the Wireless N and see what results I get.
Ok, after a few weeks of reasonably good behaviour on the 15.6.1 drivers, they're now exhibiting the same behaviour as earlier versions. No settings have been changed on the router or the drivers. It's enough of a problem now that I have to remove them and try the basic Win8 drivers that others are using.
Just signed up to this community to register the same complaint, hopefully Intel will keep track of us and offer a fix, though I doubt it. My former partner used to work at Polaroid and when they started designing digital cameras they would rush products to market and then correct mistakes or unresolved issues in the next generation of camera, without fixing the original models.... PLEASE Intel do right by your customers.
I bought a Samsung Series 5 i5 Ultrabook in February and have the same problem with a stable connection to wireless - it says Limited Connectivity about every 3 hours and I get it back by rebooting; and intermittent strength of signal, causing pages to load slowly (with a FAST laptop?). I moved in April and connected to an older router which I thought was the problem with much slower downloads, but when I connect directly to the modem my connection drops and it says "unidentified connection" - huh?

Hi, I have got the same issues on Dell Xps 13 bought a month ago. I have tried all suggestions but they don't solve the problem, but the connection is better. I've just discover that when the wifi freezes I don't need to reboot the pc, I simply activate the "airplane mode" and then turn off it, it works...
------------------------- PLEASE READ THIS: ---------------------
I don't know if this is problem is hardware or software (I hope this one) but I want to know the answer. I am not an expert, as many of you, but I've a suggestion... We should write to computer magazines (I send emails to two magazines, until now no answers) and ask for investigate this issue. I think it's useless writing in this forum... Intel isn't reading our complaints. BUT If they publish something, I bet intel will work hard to find a solution.
In addition they have tools to test pc accessories and they can establish if this problem is software or hardware. So PLEASE contact a magazine or a site (like Which?.co). I hope we will solve the problem!
I think I'll wait a month and, if no solution are found, I will buy a new card... Has anyone replaced this intel card with another??? Are there problems with Windows 8 and secure boot?
Hi Melissa, we have the same issues (wifi freezes, need reboot, high/low signal in the same position...). I think in my case airplane mode completely turn off the card, maybe in your case this isn't true.pheraps my previous post isnt clear, when my wifi freezes I turn on-off the airplane mode, not when it's "working"... This issue is absurd: wifi card costs nothing (search intel n6235 wifi on eBay... 30$!), my computer costs 1300€! That's why I will call dell to have my card changed.
I have absolutely had it. Back and forth with Samsung past 5 days, on hold for hours, no one listening to me when I explain the problem and now to the point where they are outright REFUSING to do anything more for me.
The latest driver is still no good for me. I don't have the rollback option either (it's greyed out) someone please help me get rid of this driver and try the generic windows driver.
I purchased a 6230 but just can't get this laptop apart. There are no guides available for it online (NP700G7C-T01CA) and the adapter resides underneath the keyboard.
By the way, A Samsung manager just hung up the phone with me moments ago. His final answer to me was "the service center replaced the card and reported it fixed so there is nothing we can do for you" after reiterating to him about 12 times to stop calling it "fixed" because if it was I wouldn't be calling you right now, he hung up the phone on me.
Before I go absolutely bezerk over here I want to sever any more communications with Samsung regarding this issue as it is not good for my health. It is concluded that getting them to acknowledge the problem even exists is useless. And to be frank, Intel, I blame you for that because they state there is no information in their system to state that there are any known problems/recalls with any of their products so obviously all this here was never communicated to that company.
By the way Intel, you instructed us with issues to take it up with the manufacturer especially those of us with warranty, I did just that, endured a month without my laptop, and now have spent 2 weeks chasing Samsung for the results I have described and ZERO solution. So now the ball is in your court.
So can anyone provide me with a reference for dissembling this laptop? Or instructions to completely remove the intel drivers and try the windows drivers?
7 Series Samsung NP700G7C-T01CA
With 'N' mode disabled the card is stable otherwise connection drops, limited connectivity, etc etc.
Already sent in for service to Samsung once, they replaced the card with the same faulty card and problem came back after about 10 days of use.
So have we recieved any further updates?
I joined and completed the info for Intel, fortunate that i no longer get drop outs whilst using the laptop however i still have other issues.
1. Speed of laptop as dramatically reduced.
2. When laptop goes into sleep mode or battery dies, there is no wirless connection. I have to start the laptop up, find no connection and then restart the laptop again. Once restarted it takes the wifi about 1-2 mins to actually locate and connect to wireless.
Thanks for the information.
I've filled out the form last week and got an automatic response from the wireless team, which I did not quite expect...
I have the Samsung NP770Z5E. Not sure what version 15.5.6 they are talking about in that answer BTW.
