Network adapter (again)

I have a Surecom network adapter.
Solaris 8_x86 didn't recognized it.
I've downloaded a driver for Realtek chipset, I've done everything written in readme, but it doesn't work. 2 problems: 1.after doing everything from readme.txt, ifconfig -a shows 2 interfaces and ping works only with numberedIP (not www.yahoo.com), ping. 66.218.71.198 the answer 66.218.71.198 is alive and ping www.yahoo.com the answer is unknown host. 2.After restart, the OS says bad address, even with auto-dhcp. It does not retain the interface; it retains only the loopback.
Am I doing something wrong? I have used touch reconfigure, but it doesn't work. I am waiting any sugestion.

The first problem is that your DNS is broken. You need to have a DNS server on your network somewhere (our externally), and Solaris needs to be configured to use it. Normally, this would be setup via DHCP, but without knowing the details of your network, I'll suggest the hard coded fix: Make sure you have "hosts: dns" in your /etc/named.switch file, and list your dns server(s) in /etc/resolv.conf
I'm not sure about the 2nd problem. Which address (MAC/IP/DHCP/etc) is it complaining about, and when does it happen, exactly?

  • Windows 8.1 Enterprise Evaluation- Strange behaviour of network adapter

    Hello there are discussions and questions around this community about network adapter dropping connection while system is running. But I have found unique problem with my network adapter driver.
    I have tried to state my problem as clearly as possible. Please ask if any detail is required.
    My network status shows no access on following occasions:
    1. On alternate system wakeups.
        eg:  
    a. System boots up 
    Internet accessible
    no problem
    b. I put system to sleep(first time) and wake it up
    No access to internet !!!
    When I check in network and sharing center not even adapter shows in disabled status.(See video from the link given below).
    c. Without restarting system or without installing network adapter again,  I put system to sleep again and wake it up (2nd time).
    Internet accessible
    d. I put system to sleep for (3rd time) and wakes it up.
    No access to internet!!
    If I put system to sleep again and wake it up definitly I get network access.
    2. If I switch off the modem before windows shutdown completely or in the process of shutdown, next time when I boot system, even though the modem is switched on before booting the system, No internet access tooltip will be shown on network
    sysbol.
    Another strange behaviour is on no internet access status, I start installing adapter, and it loads required files and prompt me to click "next" and "click" install.
    But the thing is before I go to "next" button, I will get network access as shown in this link
    http://youtu.be/sPlXVEiYBeo. Ignore virtualbox adapter. Same behaviour was there when there is no vbox adapter. Same was happening in Windows 8 Pro, but not in windows 7, so that there is no H/W problem I think. 
    Any idea on how to fix this or any alternate solution ? 

    Hi,
    Firstly, access your network adapter official website to get the proper driver applied to your system.
    Then going to Control Panel > Device Manager, right click your adapter > Properties. Under the Power Management tab, make sure "Allow the computer to turn off this device to save power" checkbox unchecked.
    If it still persists, try to disable "fast startup" as below steps:
    1.In Control Panel, open the Power Options item.
    2.Click the Choose what the power buttons do link.
    3.Clear the Turn on fast startup (recommended) check box.
    4.Click Save Settings.

  • Broadcom 802.11n Network Adapter not working on Windows 7 64bit

    As the title suggests, my laptop (Alienware m17x) is installed with the Broadcom 802.11n Network Adapter and Windows 7 64bit Home Premium.  I have had several other driver incompatibility issues with Windows 7, but those I have slowly been able to resolve.  This however just cropped up after two months of successful use.  Yesterday it started failing to connect to the internet, telling me that no wireless connections are available.  I live in a dorm, and everyone else on my floor has successful wireless, including my Ipod Touch, PS3 and XBox 360.  I called Alienware/Dell Support and we spent hours trying to fix the problem and all look well until I rebooted my laptop this morning and the same issue reappeared.  When I reboot my laptop, all I get is a notification that no networks appear in range.  If I uninstall the broadcom chip and let windows install it after a boot up it works until the machine is rebooted a second time.  I have tried over a dozen windows 7 drivers for the chip, and about half a dozen vista drivers and they all have the same results, works on the first boot, fails every time after that 

    Just registered to say, on an Alienware M17x system as well running Windows 7 Ultimate, here is a link to a solution that worked exactly for me:
    http://forum.notebookreview.com/alienware/436486-guide-properly-solve-wireless-connection-problems-m17x.html
    All I did was section I.a. If the link is down, I copied the only section that I needed to follow out of this guide, in order to get my wireless to work repeatedly without having to uninstall the wireless driver every single reboot. Now it works perfectly,
    already connected to a wireless network on startup.
    I.a. Disable Device sleep on disconnect
    Some newer Nvidia Ethernet drivers have a feature called Device sleep on disconnect. This is the culprit. Normally, it should only put the Ethernet adapter to sleep when the cable is disconnected, but it's buggy and thus kills the wireless connection as
    well.
    Follow these steps to disable this feature on your Nvidia Ethernet Adapter:
    1. Open the Windows Device Manager by hitting Win+Pause, then click on Device Manager on the left side.
    2. Double-click on Network adapters.
    3. Double-click on NVIDIA nForce Networking Controller (yes, that's the wired Ethernet adapter indeed).
    4. Click on the Advanced tab.
    5. Select Device sleep on disconnect.
    6. Set the Value to Disabled. 
    7. Click OK and wireless should work again (might require a reboot afterwards, but probably not).

  • Update to iTunes 10.6.3.25 disables network adapter

    I am having a very difficult time trying to update to iTunes version 10.6.3.25 on 32-bit Vista Home Premium.  The installer completes successfully, but about 2/3 of the way into the install (I am assuming when the Apple network adpaters are installed), I lose my internet connection.  It doesn't matter if I am WiFi or if I am plugged into ethernet.  Not a problem, except that I can't re-establish it after the install is complete. 
    My initial update attempt was done using the Apple software updater.  However, that install crashed.  I removed iTunes completely and now have been using the installer program from the iTunes website.  I have downloaded the installer multiple times, each time with the same result.
    The real PITA is that a simple uninstall won't restore the network adapter performance.  I have to use a restore point to get back to where I can connect to the internet.
    Any suggestions about how to fix this problem?
    - Pete

    I'd try the install again, and then apply TG10987's instructions from the following post:

  • Surface Pro 3 / "Windows did not detect a properly installed network adapter"

    Hi all,
    I've been running the Windows 10 Technical Preview (9926) on my Surface Pro 3 successfully
    since January. Unfortunately, I lost all internet connectivity today.
    The problem started when I noticed the type cover wasn't working (pressing keys on the type
    cover wasn't registering any typing on my screen) and my USB mouse wasn't working either. I tried removing and reattaching the type keyboard but this didn't fix the issue. I had to use the accessibility on-screen keyboard to sign into Windows (thankfully touch
    was still working). Once I signed in, I still didn't have typing or cursor ability, so I decided to restart the computer.
    Then it got worse. I noticed the Surface Pro 3 was stuck on "restarting" and wouldn't
    actually restart. Since it wasn't responding, I held down the power button for about 10 seconds until it turned off. When I turned it back on, the type cover and mouse started working again.
    Unfortunately, this is when the WIFI problems began. I had WIFI for a few seconds, and then
    I lost internet. I disconnected/reconnected but there was a yellow triangle telling me there was some sort of problem. So I restarted the Surface Pro 3.
    When it came back on, there were suddenly NO connections available at all. Opening the "Network
    & Internet" settings page gave me the message "Windows did not detect a properly installed network adapter". And here I am, without internet on my Surface Pro 3, borrowing my friend's computer so I can type this message (he is also running
    Windows 10 build 9926 on his laptop and is able to connect to my WIFI with no problems, whereas my Surface Pro 3 cannot even detect any networks). I have not dropped or damaged the SP3 in any way, and there have been no storms or power outages or anything
    of that sort. Any ideas what could have happened to the WIFI on my Surface Pro 3?
    Thanks for your help...

    Hi Ethan,
    Currently, there are a few compatibility issue between the current hardware and Windows 10 Technical Preview (9926 build), this is mostly related to driver compatibility issue.
    I suggest you download the latest network adapter driver package to install, when it is finished, check if it appears under Device Manager.
    Surface Pro 3, Surface Pro 2, and Surface Pro firmware and driver packs
    https://www.microsoft.com/surface/en-us/support/networking-and-connectivity/install-wireless-drivers
    You can check if you can install the latest firmware package for your device.
    Here is an article to talk about such things:

    Hi peye,
    I don't believe the problem is necessary the platform service, but a combination of your Anti-Virus and the Platform Service.
    Try this:
    Change Platform to Automatic again. Disable or temporary uninstall your Anti-Virus and see what happens.
    Report back.

  • No network adapter or drivers seen in windows 7 after Boot Camp 5.0.

    Mac Book Pro (newest). I Did a boot camp install of windows 7 home premium. Allowed 76 Gigs for that partition. Thought that would be enough. Did just fine.  Got all done and I cannot access the internet wifi or eithernet in Windows, when I trouble shoot with network diagnostics in windows it states no network adapter present, let alone the drivers for that adapter. I thought Boot Camp 5.0.1 did all that for you. There was no instruction to install drivers to a disc or thumb drive. Whent back to the MAC side and made shure I was sharing eithernet and wifi. When i do select share eithernet and WIFI I lose internet on the MAC  totally. I am about to lose it. I've been looking all day for the solution. Can someone help me.

    It appears you did not read and follow the Bootcamp Installtion Guide. The guide was the first menu item when you started Bootcamp Assistant. You did not download the Windows drivers when you ran Bootcamp Assistant. You then did not install these downloaded drivers when you first stated Windows.
    Start Bootcamp Assistant again. Select only the menu item to print the Bootcamp instructions. Read, and follow the instructions.

  • Atheros AR5007EG Wireless Network Adapter - With any driver: "The device instance name is invalid"

    Hello there,
    I was trying to install various "Atheros AR5007EG Wireless Network Adapter" drivers, with versions ranging from 2007 to 2010, both from the manufacturer and specifically for this computer (a Fujitsu Siemens Esprimo Mobile) and others from here:
    http://www.atheros.cz/atheros-wireless-download.php?chipset=22&system=3
    All of them are for Windows Vista 32bit.
    The computer had previous drivers installed and working, but also had a network problem. In the process of figuring out what was causing it, I tried to install newer drivers to see if that was the problem. It turns out the network problem was due to a different
    thing that is now fixed (some dependencies of the WLAN Configuration service were turned off), but I'm still stuck installing the new drivers.
    TL;DR:
    However, every time I install new drivers, after install, Windows says that
    "The device instance name is invalid", regardless of what drivers I install. I even tried to install drivers for different hardware in that slot just to see what it told me and IT STILL gave me the same error. I also tried to uninstall the
    current driver, checking the box to delete the driver's software, running CCleaner and then deleting
    "athr.sys" from the Windows/Drivers folder and
    "oem8.inf" from Windows/Inf as those files were referenced in the driver's properties. The install still gives me the same error.
    The fact that it gives me this error with any driver leads me to believe it's Windows' fault and not the driver's.
    Note: I am translating from the original in Portuguese. "The device instance name is invalid" is the closest/correct translation and seems about right with the info I find online regarding the english version of Vista and how it refers to devices.
    This (https://groups.google.com/forum/#!topic/microsoft.public.development.device.drivers/yFa_XnlcLJQ) and this (http://finderr.net/windows/pt-PT/O-nome-da-inst%C3%A2ncia-do-dispositivo-%C3%A9-inv%C3%A1lido-/2082573452) also seems to confirm that, though it
    doesn't help me. It may be that the text is actually different in english Vista but I also searched for driver instead of device or stuff like "The device instance name appears to be invalid" and can't find anything either.
    I also did SFC /SCANNOW a while ago and it found no errors.  I then repeated it again after this problem and this time, SFC found errors BUT it couldn't repair all of them. Here is the CBS log:
    https://www.dropbox.com/s/bayum2rsezxpmre/CBS.log
    Thank you for the help!
    EDIT: The Notebook model is a Fujitsu-Siemens ESPRIMO Mobile V5535 and their support drivers can be found here (after specifying the OS and model):
    http://support.ts.fujitsu.com/download/ShowFiles.asp
    EDIT2:
    The last SFC /scannow scan repaired everything left to repair. The system restore option can't be used because the earliest one still has the (suposedly faulty) drivers installed.
    This computer has a Win Vista serial number, but no CD and the second partition doesn't have any kind of backup. The second partition is empty though. So, as a last resort, if I really don't have a choice, I'll try to do an upgrade install to see if that fixes
    it and if that still doesn't fix it I'll have to move everything in the users folder to the second partition and format the first which is a bummer :/
    EDIT: Here is the setup.api.log that was inside C:\Windows\Inf and details the instalation process of all the drivers:
    https://www.dropbox.com/s/tyxs1e4r7rxofch/setupapi.dev.log
    I'm still trying to read into that setup.api.log file.

    So, can I assume that the only way to fix this error is to download an iso of Windows Vista, unninstall my service packs, upgrade install Vista, run Vistalizator to change the language to Portuguese and then install Service Pack 1 & 2?
    EDIT: Alright, so I formatted the thing since the driver bug wouldn't give me a break. The details on that can be found searching for the same thread title either on tomshardware or vistaforums if anyone happens to find this looking for the same error.
    I have a real knack for bumping heads with errors that nobody else gets that somehow turn into unfixable bugs. At least if someone else searches for this problem they'll know what to do.

  • How can I set ne2000 network adapter in Solaris 8 for x86

    I am a beginner. I can not set a ne2000 compatible network adapter(isa) in Solaris 8 for x86.
    I do follows:
    write the file ' /kernel/drv/nei.conf ' with ' name="nei" parent="isa" reg=0x1,0x0300,0x1f interrupts=10 '
    and use the command: drvconfig -i nei --failed
    use the command: drv_add -i nei; devlinks; --there is no the command drv_add
    use the command: touch /reconfigure; reboot
    after reboot, use the command: ifconfig nei0 plumb --failed
    Did I miss something obvious, or what driver should I use?

    After backing up the suspect hard drive, I ran Disk Repair on it and found no problems. Then ran Disk Warrior again and no problems. It is a Hitachi, btw.
    As for the PrefPane issue: Repairing disk permissions on the main volume and on the partition that holds the system did not make any difference.
    Reinstalled the 10.5.8 upgrade, performed safe start and then repaired permissions again. Still getting a blank PrefPane for network.
    Next step is to try and trash the System Configuration plist and Network Interfaces plist.

  • Apple itunes installed network adapter and wiped my wireless out

    On Windows Vista x64, I tried to take the update for itunes and it said it failed, to try download only (which has not been working either for me over past year; I always have to uninstall and go to the site to download/install it myself).  But my internet stopped working 5 days ago (my wireless adapter inside laptop cannot find any networks ever; nor did my ethernet connection work to overcome this) and my first line of defense was to use sys restore; low and behold, there was an entry for the time period it stopped working that "apple network adapter installed" but no matter which restore point I tried to use anywhere around that event, it always came back with errors and stated no changes were made; still no internet either.
    I have uninstalled the hardware thru device manager and tried to let windows reinstall it with drivers, but that doesn't fix it either.  I even downloaded onto a flash drive the original driver that has since been updated by Intel for my Intel Link 5100 wireless adapter, but still it will not work.  The ethernet did start working once I installed the old original driver for it, but even last night I got the error while plugged into my router "limited connectivity" meaning no internet. I then tried uninstalling all apple programs and kept being blocked from doing so (sounded viral to me so I ran norton power eraser, spoke with support, even used couple other programs for spyware malware bootkit/rootkit etc).  Now I finally got all the programs uninstalled, cleaned the registry, and still I cannot get the wireless adapter to work.
    I have spent days on this issue, seeing other discussions over the past few years where this has happened before (an update with apple's network adapter installs and wipes out the actual hardware adapter) but each time it only affects certain models of wireless/ethernet adapters.  Guess this update got mine.  I am trying NOT to have to restore my computer to factory condition as it is over 2 years old and that will mean millions of updates to all microsoft programs, drivers, etc.
    Does anyone have any ideas that will fix this?  I can send you my specs if you need them.
    Sheila

    Thx for the suggestion, but this is the post I originally found and figured out what went wrong, However, as I stated in my question post, I have not only uninstalled, scanned for hardware changes (w/o reboot) and rebooted and watched windows install device drivers for both lan & wifi, yet the wifi absolutely will not work now.  I have the ethernet working since installing the old original driver, and today I was able to actually get back up to the last wifi driver from intel I had before itunes wiped it out.  But still no wifi.  My intel program and intel's system checker I used on their website states:
    WIRELESS NETWORKING INFORMATION
    Wireless Networking Product
    Intel® WiFi Link 5100
    Driver Version
    13.4.0.9
    Intel PROSet/Wireless Version
    not detected
    Software/Driver Status
    Newer Driver Available
    Latest version available
    13.5.0
    Hardware IDs
    PCI\VEN_80​86&DEV_423​2&SUBSYS_1​2018086&RE​V_00
    and I can't get the Newer driver to install without errors stating it will not work with my ACer setup.  But at least I got from v12.0.0.73 today to the one above.  I reinstalled Itunes today hoping that would fix anything I'd removed and the version was like 10.3.x.x.x.  Then I uninstalled from device manager & rebooted hoping wifi network adapter would start working again, but alas, no..
    Hope someone can help me soon, cause I've run out of ideas.

  • Yoga 2 did not detect a properly installed network adapter

    Woke up this morning, turned my yoga 2 on, no WiFi.  So I used the troublsheeter and it told me there was no properly installed network adapter.  Does that mean my wifi card is dead?  Anyone else have an issue like this and find a solution (besides replacing a dead card?)
    I did:
    1) reinstalle drivers via usb from another machine
    2) used a system restore point from a few days ago
    Neither action had any effect.

    Well I just set it to airplane mode and while I had no wifi it never told me that there was no network adapter cofigured.
    Also, when you set it to airplane mode the wifi signal icon changes from bars to an airplane.
    I think the adapter must have stopped working and then.. started working again.  I can't figure out what else it could be.

  • K9VGM - network adapter occasionally failing

    Hi friends,
    I have a new computer based on a K9VGM board. Everything is running fine until after some random number of hours - between 6 - 80 hours, when the network adapter (on the motherboard) suddenly fails. It may have to do with the network load, but it doesn't seem to be related to the temperature in the room.
    When it fails, everything else on the machine is running fine, except for the network adapter. I can't control it all from inside windows, any "disable" or "repair" on the network connection or network adapter fails, and the window just sits there. It seems like the OS can't communicate with this piece of hardware at all. After a reboot the computer runs fine again, until it happens the next time.
    This is actually my second K9VGM motherboard in this machine - I returned the first one to the reseller, with this error. They supposedly tested it, and confirmed the problem, and sent me a new one - which has the same problem...
    All drivers and updates should be applied, according to the MSI live update tool.
    Any tips on ho wto proceed? I am not so keen on sending it back again, to receive another MB with the same issue. I am tempted to just buy a cheap NIC PCI card and put in the box...

    I have held off on doing anything on this - and now the machine has actually been running without any network problems for more than a week - so maybe it was just the previous board that was faulty, and the new one had a temporary hiccup (not reoccuring problems).

Maybe you are looking for
