Lan problems on P55-GD80

Hi,
I'm on my second one of these motherboards and they both exhibit the same fault with the same workaround. On boot the primary LAN devices are not visible in the device manager under Vista, sometimes both LAN devices can vanish. I can get them back by shutting down and clearing the CMOS using the button on the board. I thought it was a Vista issue but if I boot a standalone backup environment, Linux based I think, that can't see the LAN devices either. I think the effect seems to be triggered by running any non windows environment, Acronis or Paragon backup seems to sometimes trigger it. However I have seen the devices just disappear when windows was running.
I did find an entry on a German website, from what I could understand there was a similar issue with a similar board and a BIOS upgrade fixed it.
I have logged a case with MSI, I'll let you know how I get on.

Lan Problem

I'm having a lan problem, which I already made a post on this forum
SEE THIS LINK
Well, it's back! I get disconnected from the Internet without any reason (my sister has no problem). When I go to Network Connections in Control Panel to disable enable the lan, the lan doesn't enable. When I try to roll-back driver, update driver, or uninstall in Device Manager, Device Manager only freezes.
Does anyone have any suggestion aside from RMAing the board because I live in Hawaii and shipping to RMA it would cost about $40 bucks!
I tried installing a pci lan before, but it was an old one so it was very slow, but no issues.
EDIT: I also tried double-clicking on the lan icon on my taskbar but the window that is supposed to appear only appears in a fraction of a second and then disappears.

last week i did a fresh reload of my OS for cleaning purposes, and i had same prob.. internet worked off and on, then froze.. other things froze it too like device manager.. this didnt happen with my last copy of windows, so i was sitting there like .. anyways... installed all driver updates, SP1 and all, nothing happened... i got fed up with it and just said screw it , and i reloaded again... now everything works fine... my friend and i were thinking it might have just been a corrupt install, or a corrupt install of some of my drivers/updates from windows... b4 you RMA board, try a fresh copy of XP (with just new drivers and SP1) and see if you have the same problem

K7D Master-L with LAN problems

I've just completed construction of my new K7D Master-L based machine and am running into LAN problems. The first K7D Master-L I received had a bad IDE controller on it, and now the replacement board has intermittent LAN issues.
WinXP Pro installed fine, and I was able to install the LAN driver from the MSI CD and get things up and running fine. After about 20 minutes or so, the LAN connection drops out and then comes back a few minutes later. This cycle repeats over and over. There are no duplicate IP addresses on the network, there are no errors in the XP system log, and all of the other systems on the network continue to work fine during these down periods.
I checked on the MSI website, and there are no drivers available for the Intel 82551QM lan controller that is on the K7D Master-L board. Does anyone know where I can get an updated driver to try? These types of problems are most frustrating to debug.
Thanks,
Norm

Just an update to this:
The problem is definately the onboard LAN controller. I've tried a Netgear card as well as a real PCI based Intel Pro 100 card and both are working great. When I take the PCI cards out and try to use the onboard LAN, I still get intermittent outages.
Very strange. If any MSI engineers are listening, I'd love to hear your opinions. According to the OS, there are no IRQ, memory, or other conflicts that might be to blame.

Belkin wireless modem and Airport Express lan problems

Let me preface my problem by stating the obvious - I'm not very technically proficient!
That said, I've had an AirPort Express wireless lan connecting three computers on my home/office network for the past 8 months without any problems at all. All machines on the network have been able to access the internet via a Thomson SpeedTouch 530 ADSL1 modem that connects via an ethernet cable to the AirPort Express. No problems.
The network consists of my G5 iMac (ALS), my husband's Mac mini and my Sony VAIO laptop (XP Pro SP2).
I should also mention that half-way between my office and my husband's office there is a second AirPort Express that 'boosts' the signal to his office.
I recently changed ISPs to a provider that offers the faster ADSL2+ service. This meant that I had to get a new Belkin ADSL2+ modem. This is my problem. I cannot connect my AirPort Express network to the internet using the Belkin modem. The Belkin modem connects without any problem if I just have it connected via ethernet to my iMac but that's not what I want to do.
My existing AirPort details are -
IPv4 Address: 10.0.1.3
Router 10.0.1.1 (this is the SpeedTouch 530 modem)
Subnet Mask 255.255.255.0
I thought I could change the new modem's address(?terminology?) from 10.1.1.1 (which is how it came) to 10.0.1.3 and that everything would work but it doesn't.
Belkin tech support said 'the problem is with your AirPort Express' (what else would they say)?
Do I have to keep the 10.1.1.1 and change my AirPort addresses? Or should I try to set up a new network?
2GHz 20-inch iMac G5 (ALS) Mac OS X (10.4.4) Mac Mini; 12inch PowerBook; 120GB external firewire hd; Video iPod; iPod mini;

No ideas?

LAN problems in bootcamp

I've been playing Company of Heroes with several friends over LAN (3 macs and a pc), all have the latest patches to the game and are running Windows XP SP2. However, 2 of the macs seem to lag sometimes, enough that the game is almost unplayable on that computer. The imac will lag maybe 1/10 games, but it otherwise plays COH perfectly fine over LAN or even online. The other, a macbook, will lag 4/5 games even though the graphics settings and resolution are all set at either off or the lowest setting. But that 1/5 game it will not lag at all and the game plays smoothly. While either computer is lagging it will say "your video/audio settings are too high" but that can't be the problem because usually they run the game completely fine. This might be related, but I believe the one time that the macbook played fine was when the pc hosted.
The imac that has sporadic problems is a 2ghz intel core 2 duo with 1gb RAM and a Radeon X1600 graphics card. The macbook is a 2.4ghz core 2 duo with 2gb RAM and a GMA X3100 card. Thanks for any help...

It sounds as though you need to download the Windows drivers. They are included on your Leopard CD. Once you insert the disk, Windows automatically installs the necessary drivers. It works.... I've done it several times now.

Running VOIP phone from shared LAN on iMac 27" running latest OSX Mavericks

Hi, I´ve got a mid 2011 27" iMac which has been updated to the latest version of OSX Mavericks.
I connect to the internet over WIFI from the router and have shared the WIFI internet connection with the ethernet port to connect my Aastra 6730i VOIP phone.
I work from home and I am able to make outgoing calls no problem but cannot receive any incoming calls and the phone displays a "no service" message on the screen.
I do not know if this is a IP configuration issue with the ethernet port on the iMac or if it is to do with the config of the phone itself.
The ethernet is configuring the IP address on the iMac using DHCP and currently gives a self assigned IP of 169.254.xx.xx with a subnet of 255.255.0.0.
The IP address programmed to the phone is 192.168.2.6, subnet of 255.255.255.0, gateway of 192.168.2.1 and primary DNS of 192.168.2.1.
I used to have this working fine and able to make and receive calls without any manual configuration, the only things that changed recently are I updated to the most recent OSX Mavericks (10.9.4) (was running Mavericks 10.9.3 previously) and that we moved house, same iMac, same handset, same LAN cable, just unboxed it all and connectd it all back up same as before.
I am no networking pro and have tried everything I can think of so far, if anyone out there has more experience or knowledge and has any suggestions it would be greatly appreciated! (and no running a LAN cable from the router direct to the phone is not an option)
Thanks in advance

A few days after I originally posted this and I have just solved the problem, nothing to do with the iMac or the VOIP phone.
I figured out that I needed to do some more configuration to the router I received from my new ISP in order to disable a hidden SIP setting hat otherwise prevents VOIP from working properly.

Problemi Imac g5 in rete

Ho un Imac g5. OSX 10.4.6. Da questa macchine posso connettere un altro mac, (portatile OSX 10.4.3) e vederne tutti i contenuti, ma se connetto un amacchina Win XP pro riesco a vedere solo la cartella condivisa.
Se sulla macchina Win cerco di condividere tutto il disco sul mac vedo solo l'alias del medesimo. E non lo posso aprire.
Inoltre il mio g5 non si lascia collegare in nessun modo, ho la consiviione files attiva, la macchina sivede da altre postazioni ma al login rende un messaggio di errore (usn o pwd errata). Pwd mai impostata su nessun computer in 15 anni usn sicuramente corretto. Finchè usavo il 9 non ho mai avuto di questi problemi, archiviavo mezza reba sui PC!
Qualcuno può aiutarmi?
Grazie
Andrea

Yes, I supposed that tis forum is mayorly in english.
Now, my english is quite terrible, and I hope in the italian users.
May be in italy there are few Mac users.
So I retry in english.
Please do not laugh.
I have a Imac g5. OSX 10.4.6. I can connect it in Internet, upload and download, I can connect an Ibook (OS 10.3) and see all volumes on it. Connecting a PC (win XP pro) I only can connect to default public folders. If I try to share all HD (C:) from g5 I see only the alias (or win name) of c: ; c.ink and I'm not able to browse this volume.
Moreover, i cannot connect my g5 from any computer, Mac or Win, on my LAN, I see it, but the login is unsuccessful.
USN and PW are of course correct.
Until I used OS9 I never had any problem.
Can someone help me?

790FX-GD70 LAN Problems

Hello all;
I recently purchased a bunch of components on NCIX, and assembled the computer together, and everything is working extremely well - minus the LAN connections. I've never seen the LEDs light up, and all I'm ever getting in the windows properties is a network cable unplugged message in the adapter settings. I HAVE read the other postings on this board and don't think I have been helped.
I am running Windows 7 (64bit)
790FX-GD70 w/ Phenom II 955 (3.2GHz)
2x4GB Mushkin Stiletto 16000 (1333) DDR3 Ram (Upper end but not overclocked)
2x1GB Asus EAH5450 Silent Video Cards in Software Crossfire (Works great and have had no issues)
ModXStream 700w PS
Antec 900 Case (with all fans so it has adequate cooling)
I also have set up two RAID 0s (may have been overkill) But I have two SataII 250GB hard drives for the OS drive (allows me to upgrade to a SSD in future) and 2 2TB Green Drives for Data, Movies, Music, etc.
ANYWAY, everything was installed and working perfectly, but have got no response from the LAN, so a wireless stick was installed on the front bus.
I've only ever used the drivers from the site, but MAY have originally installed the disc drivers for the MOBO.
I have tried turning off the LAN in BIOS, uninstalling and reinstalling and returning on the LAN (along with doing the above with and without the cable installed) in every order and with every driver I could find. (The one on the site didn't work- so I tried MSI's Liveupdate and it found a different one - tried installing and running THAT one with the above - nothing). I've received no response from the LAN and even less from the MSI help/email system.
I've tried everything I can think of except:
a) I will try the above mentioned in SafeMode
b) I searched for these elusive REALTEK drivers that saved someone else, but I don't appear to be able to access them and viewing just the information I'd need to sign up for
c) I may try stripping all drivers off and retrying with the LAN off (in bios) since it was ON during windows install, but I've uninstalled every lan driver and deleted the device only to reinstall with the (newest MSI) drivers before turning it on SOO many times it makes my head hurt.
OH, also the cable is CAT6 (50ft) and worked screamingly well for the last computer I had hooked up here, so there should be zero issues with firewalls or router/modem configurations (though I've looked)
I've included everything I can think of, any help would be greatly appreciated. I'm trying to move a few TB of data off a main computer to mine, and it's taking a lifetime through the wireless. Thanks for any help/comments you can offer.

---------------------
Alright - Thanks to all readers so far - I've been trying to diagnose this problem for some time and put in a lot of time yesterday to no positive result.
Because I was on a computer all day, I was able to do updates with what I was thinking, and different things as they came up - but they weren't always legible/comprehensible so I will try to explain everything better and condensed for any new readers.
New Computer Parts:
790FX-GD70 w/ Phenom II 955 (3.2GHz)
2x4GB Mushkin Stiletto 16000 (1333) DDR3 Ram (Upper end but not overclocked)
2x1GB Asus EAH5450 Silent Video Cards in Software Crossfire (Works great and have had no issues)
ModXStream 700w PSU
Antec 900 Case (with all fans so it has adequate cooling - Temp always <45C)
Windows 7 (64bit)
Original Installation:
Had no issues, but installed off the supplied CDs, then updated to the MSI mobo drivers.
I had the smaller drives running on Raid Array 1 (boot) so I can in future upgrade to a SSD and the two Larger drives as Raid Array 2 for a nice and large music/games/iso/Video drive
I originally tried screwing with it a bit, some reinstalls, then got fed up thinking the MSI email thing will solve it and started installing games, norton and the like. This lead to comment about additional uninstalls disabling norton, windows and anything I could find - This was not ORIGINALLY an issue, but came to be in later installations (Sorry for the confusion).
This computer originally had dual screens, but has now been upgraded to a Plasma Widescreen (it was my plan to have this as a media/gaming computer)
Through all driver installations, I've found the LAN LEDs light up in Startup, Windows goes to its loading screen, then to a blank screen (juuust before windows finishes loading) and then to windows - On the blank screen the LEDs turn off and stay off for the remainder of the PC being on. This is ALSO the case at the router. Light is on until windows hits and remains off.
Therefore I tried every possible combination of uninstalling the router driver, turning the LAN off in BIOS, installing with and without the LAN plugged in, enabling in BIOS, and then booting windows (with and without the LAN plugged in).
Prior to this build, there was a computer in the same case, on a much, much older board that utilized the cable and everything went extremely smoothly (Win7 64 bit).
Nothing has been OCd, and there are no strange settings that I can see on the BIOS (though I will post my BIOS settings shortly).
Other installation options have been using the installation wizard in and out of safemode, using the "silent install" in and out of safe mode, and once agaion all installation have been done with and without disabling the LAN in the BIOS and reenabling it after.
What shows up is under the Network Adapters is:
"Realtek PCIe GBE Family Controller"
"Realtek PCIe GBE Family Controller #2"
(This board has 2 Gigabit Ports and yes I've always been trying both)
Both say they're working correctly, installed with the most recent drivers, and despite my error in one post, say 7.41.216.2011 (a 2/16/2011 update-most recent)
It also says (on both) that a cable is just missing, but it has been recently used on a different system and I can see the lights on the PC and router.
In the mobo manual the LEDS can be explained as such:
L-Yellow-Off -LAN not established
-On S.S -LAN link established
-On pulse -Communicating with another computer on the LAN
R-Green-Off -10Mbit/s
-On -100Mbit/s
-Orange-On- -1000Mbit/s
So I am getting a pulsing Yellow and an Orange (on) meaning a thinking Gigabit connection, good. -> Until Windows Loads
Now, during windows installation ( I believe this is typical) it doesn't pick up the BIOS-configured RAID array as a drive until you install the driver (in the windows setup). So I had to do that on every installation, until it picks up the drive, and installation resumes. I do not know if the same conflict exists with Ubuntu, but it sure appears that that is the case as it will not pick up the hard drives. After booting linux, the PC will not re recognize the harddrives until a COLD boot is performed (not recognizing the drives on reset had me a little freaked out for a bit).
Back to linux, I tried my version of 10.10, the admin's version, and an above listed ~8.2 Golden Heron??? Version of Ubuntu. When BOTH the v10s were loaded, it appeared to be loading just fine, with the Ubuntu logo and progress bar/balls, then the black screen, and then it wouldn't come back. The start up sound would activate, but I could not receive any visual. I originally thought this MAY have had something to do with the fact that I'm using a Plasma TV through the HDMI connection, but if the load up screen showed up, I can't understand why it would flake out.
Anyway, to cover all bases, I then tried the v8 cd, and it booted (with a fair share of ugly flickering pre load). No hard drives, but it DID allow me to check out the Connections - and it picked out the same thing, same name, same location, cable missing and couldn't get it to work.
Now at this point a question was asked about my PSU as drives were "falling out" so I supplied specs:
OCZ ModXStream-Pro 700W
I thought that should have been more than ample for this set up, but I will check the Specs...
OCZ700MXSP
10A
Output
+3.3,25A
+5.0,25A
+12V1,25A
+12V2,25A
-12V,0.3A
+5Vsb,2.5A
+3.3V&+5V150W
+12VCombined,552W
Total Output, 700W
So I shouldn't have an issue with 4 drives, 1 DVD, and 2 sticks of ram.
At this point, I was getting tired and frustrated and tried some more Safe mode possibilities and Reinstalls, and in my frustration/orvertiredness I pulled off all ATI drivers that I thought MAY be conflicting (to install LAN FIRST) such as a RAID controller (stupid) and the Crossfire drivers (thought maybe PCI bus was overloaded or in conflict if the LAN is on the same bus? - I was overtired) Anyway, thinking I could get back into windows safe mode was a little optimistic and I had to settle for Windows repair (oh joy) and I COULDNT get the raid drivers to be recognized again - Found out later that the USB drive I was using to move drivers with had some issues with corruption..ANYWAY in the windows repair/select driver window I plugged in a 500G external and did the ol' Ctrl C Ctrl P and copied everything I needed on the raid array and blanked it to reinstall windows.
Now silly sleep deprived me couldnt get the main ATI driver to load (corrupt files and didn't realize at the time) and the ATI mobo driver didn't install, so I used the CD, but then I was just replicating the above test,as I installed the LAN drivers post ATI Mobo drivers (still don't know why I did that). Redownloaded newest drivers onto the external, and went to bed.
Anyway, on to today, reblanked the drive, installed windows WITH LAN OFF in BIOS, installed Windows again, installed LAN and reenabled in BIOS to the same results. Did a repair installation, with it enabled and plugged in, same results.
Post ANY installation, as soon as the LAN is enabled (if it isn't already) a message pops in the bottom right saying Drivers were installed correctly.
If it is installed with LAN off, a message pops up saying "The Realtek Network Controller was not found. If Deep Sleep Mode is enabled Please Plug the Cable."
But once, the LAN is enabled, on Windows boot it once again says it was installed correctly, but doesn't have a cable.
Right now I'm sitting with a computer with a fresh Win 7-64 install and LAN drivers, and I will try installing the mobo drivers and reinstalling the LAN again (if nothing works) but I'm fresh out of ideas. I'll see what I can hammer out in Linux too, but it appears so far that we're getting the same results (connected but no cable).
Anyway thanks for reading my novel, and once again, any help would be appreciated.

Start up problems iMac 27"

Would anyone be able to help?
The power in the house has been down, and now my iMac doesn't start. (it is a bit more than a year old). When I push the power button on the back of the screen, the fan starts on quite high rev and go for a minute or so, then it turns itself off. Some times thescreen lights up and the tone signal goes off, but the it does again.
I have ahd this problem onece before, and the it was cured with a Power Conroler Unit something reset. I can find that instructions on the internet unfortunateley.
Can someone help?
Many thanks in advance Ove

The first thing you should do after getting the machine up and running is buy yourself a decent UPS, they can be for less than $100. Get one with a USB connection so you can connect it to your iMac and then control it.
I would recomnend doing a SMC and PRAM reset first:
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Fans run full speed on stand-by and burner problem iMac 24-inch early 2009

In standby sometimes the fans are running at full speed. Also with burning some CD or DVD's the burner makes an awful grunting sound.
For a 2 year old Mac I did not expect to have these kind of problems!
Resetting the iMac does not help. Might this be a Lion problem?
Optical Drive is running at 4800rpm, normal 798rpm
Hard Drive at 5903rpm, normal 1599rpm
CPU at 3598rpm normal, 1200rpm
The burning problem only happens sometimes, not with all.

What did you do to reset the imac? Problems like these are "sometimes" solved with an SMC reset.

LAN problems in Vista

Hi all, I have a computer running vista with NVIDEA LAN. For some reason it decided to add LAN points and now I get I cannot use LAN to get to the NET, radio works OK, I get that the LAN port is unplugged, My router says its not, the cable has been tested
and replaced with the other machine. I get that the LAN port is LAN 2 cable unplugged. (lights on computer also indicate connection. The router shows slow flashing light and goes red when computer shut down. All that indicates its a software fault / glitch.
I have tried to discover the reason and have discovered that there are siblings for LAN port all having the same irretrievable but in same location reg but added with sibling numbers.
I cannot "delete" the driver / item, which if I could would mean all LAN wiped but "refound" on machine restart. The machine appears to remove the LAN, but it does not.
Its annoying having to run the Radio connection as it reduces speed to the printers. Any body any ideas. This started after an MS update some 3 months ago.

Proxie_dk,
Also,
You might want to make sure that you have done the following to try and help resolve or workaround the problem more:
Make sure you have set the correct timinns and voltages for Mushkin memory in BIOS, more information at Mushkin website under support.
Make sure you have the latest version of the BIOS for your motherboard, as several manufacturers did release updates for the problems with NVIDIA and Creative compatability. Look at support section on the XFX support site.
Make sure you are using the latest motherboard chipset drivers available from NVIDIA. 5.25 is the latest, and the international package is here.
Make sure you are using the latest graphics drivers available from NVIDIA. 86.8 is the latest, and the international package is here.
Also, perhaps not as important as the above, make sure you have the latest Windows Updates installed using Microsoft Update.

Red light headphone jack problem iMac 27" 2011

I have a problem with internal speakers. I searched forums and I think is a problema about the connector, the red light in headphone jack is on. I cannt hear from internal speakers sometimes and now it's allways. I need to plug a headphone or external spekaers to get sound.
I buy the iMac about 2 month ago. May I send the computer to the store or can I fix it?

Wind PC barebones onboard lan problem

This is my fourth barebones I've built. The onboard lan does not appear to be working. There are no lights at the cable connection and windows says a cable is unplugged. I installed the drivers off the msi disk and device manager reports the adapter as enabled. Any ideas. i am currently using a wireless adapter but am concerned there maybe a mobo problem. Appreciate any help. Thanks

If the port does not light up when you connect a good known working cable, and device manager says the network controller is installed and working, then your network port may be broken, in which case there is not much you can do but RMA the unit for replacement.

K8NGM-V, Onboard-LAN problems

Hi, I'm having some serious problems with the onboard LAN card on my K8NGM-V board. I've been trying alot and I cant get it to work properly. I installed the latest drivers from nvidia (nForce 8.26) and the card is detected and installed as "nvidia nForce networking controller", after a reboot it is assigned an IP from my DHCP router, so far so good. But when I try to access the internet (or my router which I'm directly connected to) it's not working as it should. I'm only getting like 25% successrate when I'm pinging an hompage or a LAN device. It's going REALLY slow to connect to webpages, most of the time the connection times out.
Right now I'm using a PCI network card, which works great. So the problem have to be with the onboard lan.
If anyone have the slightest clue to what could be wrong, please post!

Some nVidea lans seem to have some problems. I'm not sure wether the follwoing will be a solution for your adapter, but trying won't hurt you.
Goto Device manager and look for the adapter. Select Properties -> Advanced and look for Offload Checksum. Set it to Disabled, restart and try your connection. If it doesn't do anything, simply set it to what it was.
Edit: also, check for adware/spyware/virusses and check your firewall settings. Do you have a sperate modem? If so, what happens when you skip the router and connect directly to the modem?
