Just wondering if anyone else has had an issue with the built in wireless card the Atheros AR5007EG? mine seems to have died on me. On booting up it connects to the wireless network and then after a few seconds I cannot get any websites etc even though its saying connected if i then repair the connection it cannot re-enable the adapter then in device manager it reports an error saying the device cannot start, I then have to power off the laptop before it will work again and then the cycle repeats.
At the moment I have plugged in a Belkin 54g wireless adapter to get back on the internet.
Anyone have any comments on this? also wondering on sammys repair times or should I just get one of those intel N cards and replace myself?
I have updated the BIOS and checked all settings aswell as ran the samsung recovery with the same issues so pretty much guarantee the wireless card is faulty.December 30, 2008 at 9:11 pm #177261preetkkMember
My Samsung NC10 is fine but on my Desktop PC (custom built) I had a Linksys PCI Wirless N card in it and a NVIDIA 7300LE PCI-E graphics card. Whenever I installed the graphics cards drivers from supplied disk, windows update or from NVIDIA’s website (basically anything other than what comes with Windows it self when just have Windows XP or Vista installed and have basic graphics support) the wireless card would work fine for about 2 minutes and after that would just disconnect from the connected network and then never connect again or search for any other networks or work with any other networks. Then I would have to restart my computer for it the wireless card to work again.but once again it would stop working after a minute or two. But in device manager it said the card was functioning properly.
If I roll back the Graphics Card drivers to Windows own then restart the PC my PC would work fine except the fact then page scrolling would not be smooth, unable to watch videos and unable to play games.
I have two of these wireless cards and both work fine in another PC which has a ATI AGP Graphics Card in it. So I know the wireless card is not faulty. I do not have another PCI-E Graphics Card to try. Other PCI devices work fine with my Graphics Card I have a Ethernet Card & TV Card Both work fine in PC.
I tried the following and the problem persisted:
-Formatting hard drive & reinstalling windows
-Tried Windows XP & Windows Vista
-Tried Ubuntu Operating System
-Tried latest drivers for both Wireless Card & Graphics Card
-Tried Updating BIOS
-Tried changing IRQ to Graphics Card and Wireless Card
-Also made it so the Graphics Card had no pre-set set IRQ
-Tried a USB Linksys 54g Card and that works fine with my system
-Tried using drivers made for other wireless cardsJanuary 4, 2009 at 1:00 pm #177260RobertSMember
You are not alone. I have the same problem.
It worked ok when I first got it.
I restored several times and tried different driver versions when I encountered the problem.
I even opened the Sammy up and reseated the wireless card.
That’s when I discovered that the card is only recognised (e.g. wireless indicator light on when booting), when I untighten the screw used to hold the wireless card into it’s position.
It seems the card and/or the mainboard connector is faulty.
I might try a different card before returning it to Samsung.January 4, 2009 at 2:14 pm #177262preetkkMember
Now this is weird after posting about my Desktop PC as above NOW my NC10 is having the same problem as you two.
EDIT — I downloaded the drivers from the Samsung website and reinstalled them now mine works again.April 29, 2009 at 9:14 pm #177264kh80760Member
I truely believe that I have a solution to this and it is called ‘Atheros Client Utility’ which comes bundled with the Atheros Driver available from the Samsung website. After spending about 4 days of my life working on this, you will have to read my story to get the full answer, or just go to the end of this post and read the last paragraph!
About 1 month ago, I took delivery of my new Bacl NC20 about 2 weeks ago. As an IT Consultant (Unix), and a Windows user for around 15 yrs, I felt quite configent that I would have it running quite quickly and I was not wrong.
Out of the box, I went through basic configuration and accepted the offer to take and initial install using Samsung Recovery Solution III. I setup the look and feel of laptop the way I like it and copied my files to the hard drive. I Installed Open Office and a few other programs. I then Installed and configured Mozilla Thunderbird & Firefox and copied my email, contacts and bookmarks, all of this using a wired LAN connection.
Once things were as I wanted them, I turned my attention to the Wireless connection and was able to quite quickly connect to my Wireless Router (Netgear DG824M) usinga WEP 64 bit shared key (my old laptop does not support WPA), I was letting Windows control the Wireless Network Adapter. I continued to use the laptop with wireless only in the house for then next few days with no problems and then took it into the office for the first time, where I used it for a few more days, no problem. So, by this time, things were looking very good, then my problems started.
After about 7 days fo trouble free wireless usage, one morning I fired the laptop up and it would not connect to my home router. I had a ‘very good’ signal from where I was, and when I went to view Wireless Networks, I could see my Network there with all but one bar green. It did not seem to mater how close I went to the router, it would not connect. Out came my old laptop which connected no problem. At this point, I believe that the problem occurred after a Windows Automatic Update installed and I had no idea what the problem was or what the solution was.
Over the next few days, the problem continued either at home or the office. If I rebooted the laptop, the Atheros wireless adapter would connect initially, and then drop out. It could stay connected for 1 minute, 5 minutes, 30 minutes, 3 hours but it would always drop out. I could replicate the problem at will, even if I was connected and working, all I had to do was hibernate the laptop and then start it again and 19 times out of 20, it would not be able to aquire an IP address and sometimes it would even say that the network was not repsonding, but all the time the Windows Network Connection Manager displayed my Access Point (AP) and was never less then Very Good strength.
Since it started to go wrong, I have tried the following with no success..
– Downloaded the latest Atheros AR500&EG Driver (188.8.131.52 as of 29/APR/09) from http://www.atheros.cz/download.php?atheros=AR5007EG&system=1 and installed them from the Windows XP Home Hardware Device manager “Update Driver” option from 184.108.40.206
– Downloaded and installed the latest Samsung NC20 BIOS & MICOM (version 08MQ) from http://www.samsung.com/uk/support/download/supportDown.do?group=&type=&subtype=&model_nm=NP-NC20&disp_nm=NC20&language=&cate_type=all&dType=D&mType=FM&vType=&prd_ia_cd=&model_cd=&menu=download and upgraded from 06MQ
– Changed the ‘Atheros AR5007EG’ Power Save’ value from normal to off in the Hardware Device Manager ‘Advanced’ Tab
– Restored from Initial Samsung Recovery III Backup and reconfigured by hand. This was OK initially, but then consistently started to drop connection.
At this point, the laptop was practically useless to me as I need a solid network connection which does not drop out. So, With no particular idea what to do next, I decided to re-install the Atheros Drivers again, but this time I wanted to download them from the Samsung website. I noticed that when I extracted the ZIP file, the Samsung 220.127.116.11 contents were 10mb bigger (at 32mb) than the 18.104.22.168 contents. Although I had re-installed the 22.214.171.124 driver about 10 times, I had always used the Windows XP Driver Update option from the Device Manager. This time I decided to use the setup.exe which came with the ZIP file.
When I ran this, one of the first options was to ‘install driver only’ or ‘Driver and ACU’. Interesting! I chose the ‘Driver and ACU’ which is Atheros Client Utility. After installing and rebooting, I discovered that I was not able to view wireless networks through windows as another program was controlling the adapter, and If I did want to use Window to do this then I should change the advance settings to use windows to control it. I did this and although my adapter initially connected, it dropped out after a few minutes.
I decided to put the device back under ACU control and then started playing around with ACU. Basically, you create a profile for each location you want to use the wireless and then configure the connection through ACU. Not as nice as using windows, BUT IT WORKS! I have chosen to leave Power Save disabled and have also disabled QOS because I do not use it, BUT IT WORKS. It works at home, it works in the office, it works with my new Belkin54g Range Extender which I have installed since fixing this problem (same SSID as my Netgear Router). Don’t ask me why, but the Atheros Client Utility with the 126.96.36.199 driver supplied by Samsung works!
When I feel brave (which will be after this has been working with no problem for a bout 6 months), I may upgrade the driver to the latest available and see if it works with Windows. I may even set Power Save back to normal and enable QOS, but right now, I am leaving everything as is. In fact, the first thing I did was take a Complete Backup of the C: Drive using Samsung Recovery III so that I could restore if I needed.

I had the same problem with Atheros AR5007EG on my Sammy N310.
It started after I had deleted the recovery partition and had to make bootable usb with Windows XP.
Previously when I was using originally installed windows there was no problem at all, wi-fi connection was stable with strong signal – perfect. The problem occured yesterday when I downloaded all the newest drivers from samsung site. It was the same … my network (WPA2) was found by wi-fi manager but I could not connect to it. I tried many drivers, none worked.
I solved the problem today 🙂
Plugged RJ-45 into the socket and downloaded all the updates from microsoft update site.
After reboot it works like a charm 🙂
Check it out guys 🙂March 21, 2010 at 12:49 pm #177263jeepers01Participant
