        Samsung Series 5 (NP530U3C-A0ASE), same problem. Upgrading to latest driver (15.5.6.48) didn't help, neither did changing power settings. Disabling n-connectivity was a huge improvement. Not a dealbreaker for me since I don't rely too much on wireless, but a real shame it doesn't work as it should.

          Recently bought a Samsung Series 5 with Centrino 6235 adapter and Windows 8, and could not be more disappointed. I get kicked off wifi every 10-45 mins, requiring reboot, whether at home or elsewhere.

           

          Have spent probably 12 hours on phone with Samsung and Comcast customer support, have changed power settings to max, reinstalled adapter, changed channels, etc, to no avail. I returned the machine to BestBuy and got a replacement, only to have the same issue recur. I am totally disgusted with Intel, the Centrino product line, and Samsung.

           

          PS: I had to do this post three times as my wifi dropped repeatedly requiring reboots. No other web pages running. Totally unacceptable.

            Same problem here. Samsung 5 series, Centrino 6235.

             

            What has worked for me is turning the bluetooth capabilities of the wireless card off (it seems the bluetooth and the wireless don't work well together). In device manager, under the advanced tab of the Centrino card, look for a setting called Bluetooth(R) AMP, and turn this to disabled. For me, this allows the 802.11n mode to be re-enabled, and the wireless does seem to work fine. (Just to make sure, turn off any bluetooth device that you can find in device manager).

             

            This isn't a permanent solution, but may help until Intel actually bother to reply to this thread

              SGR,

               

              That sounds so familiar :-(  I found my personal fix, it was to return the Samsung Series 5 and get my money back. I am not willing to turn off 802.11n or Bluetooth on a brand new device. I think Samsung and Intel should be doing more. Well more than nothing I guess.  Pull the series 5 off the market until you solve this issue. I see nothing but posts from people having this problem and not from Intel jumping in. Maybe i missed something but it's obviously a big deal with this wireless radio and driver combinations. When I choose a new laptop I will look closely at what radio is installed (make/model). I wish you all good luck with this issue and have a Merry Christmas/Happy Holiday's (whatever you prefer) :-)

                I too have this issue. Drops seem to be completely random, sometimes persisting for 5 - 10 minutes of no connectivity. Here is all that I know:

                 

                My computer is a Samsung Series 7 Gamer (Model: NP700G7C-S02US) running Windows 8 x64 + the Intel Centrino N-6235 wifi adapter. My drivers are the latest release (15.5.6.48), but I also had this problem with a 15.x release dated from July.

                 

                My Wifi router is a Netgear WRG614v7 (B/G 2.4Ghz single band) using Channel 11 (but I've tried others channels and had the same problem). I'm using WPA2-AES encryption. Despite my neighbors, there are only 2-3 other units on channel 11 within range of me (neighboring signals are down in the -90db range). Using inSSIDer, I can see my router's signal loud and clear (-40 db) even when my wifi adapter is claiming it cannot connect. All of my other devices (2 wired, 2-4 wireless) work without any hiccups despite my N-6235 adapter dropping out. In fact, I have had this router for years without any issue like this, and I continue to have no such issue with any other device.

                 

                Here are some CSVs from the Intel Wireless Event Viewer that comes bundled with the PROSet software. These log entries are taken from the moment my wifi went from working flawlessly to not working at all:

                 

                (Time moves from top->bottom as new->old. Basically, start from the bottom and read up to start at the beginning of the problem):

                These entries then continue ad naseum.

                 

                Essentially, my wifi works fine for a period of time, then the laptop wifi suddenly fails to authorize (apparently). Then the cycle of dropping, reconnecting, and failing to authorize happens over and over again until it suddenly decides to work. Google doesn't seem to have any info on the error codes at the end of the messages, so who knows if it's an ecryption authorization thing or just a handshake "authorization" thing. It would seem that the solution lies in finding out why the card suddenly fails to auth, continues to fail, and then suddenly goes back to working.

                  OK I see i get entry number 50 ! Well I bought a SAMSUNG NP530U3U in Chile about ten days ago and like many of you I want to drop the thing from the top of my building.  My issue is a little different it connects to the WIFI fine but then after a while the wireless disappears totally.  When I look at Adapter Settings I have the LAN card only, no wifi adapter at all. Latest drivers installed, power setting changed to max and still the same issue.

                   

                  Does anyone from INTEL read this ?????

                    To answer the question "does anyone from Intel read this?" I would have to guess they do not. Or they do but don't care enough to say "hey this is Dilbert from Intel, try a, b and c and let me know what the results are". 

                     

                    What does Samsung tell you about this? They have to be getting a ton of support calls and I would hope they have some answer. Someone should give Samsung a link to this blog so they see how their reviews are going :-)

                     

                    Good luck to you all and have a Happy New Year.

                      Such a shame. Poorly played Intel. Poorly played.

                        I have an Asus Zenbook prime that came with Windows 7 installed.  The N6235 worked great until I upgraded to Windows 8.  Since then, I have experienced sporadic network drops, usually when on battery and after some amount of idle time.  I played with the power saving settings for the network card as others have suggested, with no change.  I uninstalled the Intel driver, which is the current version (15.5.6.48) and had been installed prior to the Windows 8 upgrade.  This can be done through the Windows 8 control panel, uninstall a program option.  Once the driver was uninstalled, my driver version reverted to the Microsoft signed version, 15.5.4.45.  I assume this is the version that is part of the Windows 8 installation.  Since the downgrade, the wireless interface is slightly different, there is an additional question when connecting to a wireless network asking if the network is private or public.  I have been using the older version of the driver for a few days now and the connection problems have disappeared.  One additional note, although I do not use the bluetooth feature, it is enabled without a problem.  I hope this helps anyone who is still having this issue.

                            Hello,

                             

                            I've got an Asus UX32VD with the Centrino-6235 and Win 7 64 bit. I use a AVM Fritz.Box 7320 as Router and a D-Link DAP-1522 as WLAN Access point. When my notebook is connectet to the Fritz.box via WLAN than I have no connection problems, but if i use the D-Link then I have the problems mentioned in this thread: sporadic connection problems to the access point.

                             

                            So this is probably a problem related to the router. Here must Intel begin to investigate.

                              Same issue here I'm afraid - not sure if it's Win 8, Samsung or Intel's fault...aaggghhh!

                                Well, I am running Windows 7, and considering there are people with other brands of computers reporting the exact issue we have, I would venture to guess it is Intel.

                                  OK, I have just signed up for Intel's forums specifically to join the numbers suffering through this nonsense.

                                  I encourage anyone else (like myself) who has googled just about every combination of ''Samsung Intel Centrino 6235 wifi issues connectivity problem fix'' etc etc etc.. Who has tried every combination of power setting, every combination of driver rollback...Who has sat on the phone being told by a Samsung ''tech'' to remove and refit the battery to fix the problem on a SEALED ULTRABOOK??...Who has suffered through Samsung livechat being given links to driver downloads for laptops that do not have the same network card, who later tell you there is nothing they can do for you, who then lie and tell you that there are no drivers available before dosconnecting you...On and on I could rant.

                                   

                                  ANYONE RECOGNISE THIS SCENARIO?? - Add your voice. Sign up takes two minutes. Power in numbers.

                                   

                                  I have a Series 9 (NP900X4C-A03CA), currently on latest drivers and have similar problems.

                                  I get the Samsung default software popping up telling me 'network connection disconnected'' (or something) and any page I try to view needs at least 1 (often 4) reloads before all elements(css,images,scripts) will load and a page is fully functional. (Imagine facebook, but with no CSS and comments not working or gmail loading bar never quite getting there unless you refresh a couple of times or a blog loading with all the photos showing dead links - that sort of thing)

                                  • It is NOT my ISP
                                  • It is NOT my router. All other devices work fine. Why can't the most expensive device in the house?

                                   

                                  After writing an email to the ''Office of the CEO'' on Samsung's website, I was put in touch with a real engineer at Samsung in Ontario. He was at least sympathetic (and a nice guy), but explained that he had never heard of such a thing. I guess this is what worries me most. Do Samsung / Intel just pump products out then NEVER look at the statistics on how many support calls they get on the specific product/issue? Do none of the guys at Samsung or Intel have a poke around the odd review site or even their companies own forum and see people screaming out for at least an acknowledgement of ''Don't worry guys...we feel your pain and will pull through for you eventually. Just bear with us'' - That would be fine. S**t happens, people make mistakes. Just please tell us that we are right and not making this up??

                                   

                                   

                                  Please?

                                    I was hoping to find a solution to this problem but it appears there isn't one to be found. The common denominator is the Intel 6235 module. Anyone know of a good class action attorney?
