    [Info required please read!] Advanced Centrino N 6235 Problems/Issues.

    TechMGR

      Currently we have many reported issues regarding the Centrino Advanced N 6235 card.

       

      So far Intel, IT Manufacturers & Router Manufacturers all pass blame over to other parties.. But It could be down to any of the following.

       

           > Intel N 6235 H/W Issue?

           > Intel Software (driver/firmware) issue?

           > Laptop/PC Manufacturer issue?

           > Router (Chipset/Firmware) issue?

       

      I need your help to build a bigger picture of Hardware causing issues, please include Hardware Vender info in your reply.

       

      Keep it basic as per below.

       

      [Basic Issue]                  = Signal Strength or Connection Speed

      [Standard Used]            = 802.11n        

      [PC/Laptop Vender]      = Samsung/Dell/Toshiba etc..

      [Router Vender/Model]  = Asus RT-N66U Dark Knight

      [ISP Provider]                = SKY / BT

       

      Please help to make awareness of this post in other Forums.. It 's important we gather as much info as possible

       

      Thanks TechMGR

       

      IMPORTANT: If using 802.11n (High Throughput) Router - Performance issues will occur if using "WEP" or "TKIP" encryption.. Encryption default should be AES or AP mode. Please check settings.

          [Basic Issue]                  = Signal Strength, connection dropout's (I can't download), several package loss (I can't play online games).

          [Standard Used]            = 802.11n       

          [PC/Laptop Vender]      = Samsung.

          [Router Vender/Model]  = D-LINK DIR-600 (Home), Linksys TL-WR941ND (Work) and all others, but I don't know the model/manufacturer.

          [ISP Provider]                = Telefônica (Brazil), NET (Brazil)


          Aditional info: If enables N mode and  bluetooth amr, the ping on gateway, the ping is too high (300~500ms). If I disable bluetooth and N Mode, the ping normalize in 1~2ms. But I have sporadic package loss (0,5 to 4%), and I can't to play online games, for example.


          If I set wifi to full resources, the connection drops in every 2~10 minutes.

              [Basic Issue]                  = Connection loss, also Signal strenght is low (To fix it im in direct visibility of router antena 8m away)

              [Standard Used]            = 802.11g

              [Driver]                         = now 15.3.1.2, was tested also with 15.1.1, 15.3.1, 15,8.0

              [PC/Laptop Vender]      = Samsung NP700Z7C-S01UK

              [Router Vender/Model]  = Mikrotik 493G, WiFi card: Wistron DNMA92 using Artheros 9220 chipset,

                                                     the same behaviour with FritzBox 7140 and GemBird WNP-RP-001 repeater

              [ISP Provider]                = Giga Internet (altough it doesnt matter as LAN connection is dropping as well)

               

              Tried all different drivers from Intel , new ones, old ones, Dell ones. Cannot rollback to MS driver (is removed from PC and have no other source).

              Other hint: maybe overheating issue: after disabling the card is wokring for about 30 minutes. Then connection start to drop more frequently.

              With newest driver version additionally Im getting extreeme long ping replies every few minutes - times between 500ms to 2s and more when playing online games (=many small packets being sent).

                [Basic Issue]                  = Connection stability (frequent dropouts), Signal Strength and Connection Speed

                [Standard Used]             = 802.11n       

                [PC/Laptop Vendor]        = Asus (UX32VD-DH71-CB)

                [Drivers]                         = All drivers (including 15.8.0), but currently on 15.5.6.48 with latest PROSet software

                [Router Vendor/Model]    = Asus RT-N53

                [ISP]                 = Videotron (Montreal, Quebec, Canada)


                No problems when 802.11g is used, but I'm not satisfied with this workaround.


                Thanks for taking the time to fix this. Hopefully we'll find a fix soon.

                  [PC/Laptop Vendor]        = Samsung Tablet model - XE700T1C-A02AU running Windows 8 64bit

                  [Drivers]                         = All drivers released so far from Intel and Samsung. Only driver I see stability for most of routers used is the original windows drive that I rolled back to by deleting all other drivers. Even here I see stability issues when running N against a work TP-Link AP (nobody on the network has issues). At home the windows driver is mostly fine on Cisco Access Point (AP only) and 3COM Access Point/ADSL router although on streaming media over N it's a bit choppy.
                  [Router Vendor/Model]    = Using windows drivers - TP-Link - problems. Cisco - mostly okay. 3COM - mostly okay.

                  [ISP]                 = Not relevant but World Exchange New Zealand.

                   

                  When I hit the problem the following error is seen in the computer event log:

                   

                  >>>

                  The description for Event ID 5060 from source NETwNe64 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

                  >>>
                  The following information was included with the event:

                  >>>
                  \Device\NDMP6

                  Intel(R) Centrino(R) Advanced-N 6235

                  The specified resource type cannot be found in the image file

                  >>>>>>

                  This cycles every 30 seconds or so. Generally it seems the card cannot bind N on my installation of the drivers.


                  I have replaced the card with a Broadcom and the laptop/WiFi works a treat.

                        Brand New laptop.  Will only connect with router within 20 feet.  Once connected can move up to one room away, but spurious disconnects increase.  Will disconnnect when sleeping, and will not reconnect until returned to the area within 20 ft of the router.  Reports anywhere between 1 and 150 Mbps - while sitting in the same spot next to the router. Also shows corresponding signal strength variations between 3-5 bars,  while sitting next to the router. 

                         

                        My old laptop is still on, sitting acroos the house, reporting full signal strength and 300 Mbps.   Atheros network card on that one.

                          [Basic issue] Drops connection, Never auto reconnects when this is enabled, low signal strength, slow speeds

                          [Standard Used] 802.11g

                          [PC/Laptop Vendor] Samsung NP700z5c-S03UK bought Feb 2013.  Windows 8 64bit. Windows 8 is so awful that I installed Classic Shell. Microsoft deserve to be severely burnt for producing such cr*p.

                          [Drivers] Have used Samsung SW update to update when prompted. Update today Failed.  Device Manager then showed as 15.8.0.5. Unistalled driver and rebooted following comments on web. It then rolled back driver to 15.6.1.20.

                          [Router Vendor/Model] Buffalo WHR54G running ddwrt

                          [ISP] Virgin  UK

                          Drops connection when all other computers in house have no problems. Always seems to drop if downloading large file, usually near the end. Shows "Limited" connectivity but it is actually non-existent. Have to disconnect and reconnect. Automatically reconnect is often not shown ticked even if it set in Properties or has been ticked previously. It always reconnects. Icon does not show connection speed like my other laptops which seems a retrograde step. Are Intel trying to hide something.

                          Cannot run BBC iPlayer without breaking up even when in same room as router.

                          Contacted John Lewis Support who seemed to be unaware of this problem.

                            No drivers fix the issue, but changing some router settings made me get a much more stable connection with less dropouts.
