networking problems - related questions

GooD

Hi , i am having serveral problems with my internet WIFI connexion. But the problems are not from the connexion itself cuz if i use a laptop i can connect to internet very well.

If i use my MARVELL onboard networking device i can manage to connect with my computer, sometimes it goes well, but i often see many problems emerge from no where, like lag pike, getting disconnected, being unable to connect, losing the network (no more flashing ligths on the MARVELL connector, red cross tray icon that tell me no network wire is connected...

I can understand that my onboard networking device is maybe bugged, thats why i've bought not one, but 2 others networking card (a linksys and a d-link). With both of them, when i plug the wire on i get the tray icon 'detecting network ip...' , thats cool but when i manage to connect to internet im unable to do it, i got a 'no answer from server' msg...

How can it work on another pc (laptop) ? work sometimes with my onboard networking device and NOT work with any of the 2 brand new networking card i've bought ?

Any idea of what can cause this ???

I was wondering if seomthing can interfer with my netowrking card on the PCI slot ? is the motherboard can have anything to do with it ? I know im using a beta bios (510-2, well known and use by many users tho...) can this cause a problem like that ? Everything else is working great on my computer ...

Problems are growing in numbers each week when i continue to use MARVELL onboard device... i defenetively want to use my PCI network card =( The first month i was using my MARVELL device and it was doing well... thats soooooo weird...

I've formated and it didnt change anything...

any help or tips will be appreciated... im running out of ideas....

I have submited this problem to my ISP and since its working very well with another computer im waiting for a 'its not our problems' answer :Pwned:

Are you connecting through DHCP or a Static IP to your router? Do you have a lot of other wifi equipment that you are using in the are like a cordless phone? Also have you got any encryption enabled on the router. If you have multiple wifi cards in one computer that will also cause this as they are all trying to compete for the same connection. You need special drivers for that to work propperly and there is no point in doing it unless you have seperat networks you are connecting to with seperate IP's.

I said its a WIFI connexion and i hope i am not wrong, its a PPPOE internet connexion, i have no routers, no WIFI stuff on my computer, i have a wire that go from my network card to a little device (decoder ?) then go straigth to the antena. (it use an antena at the end, thats why i said it was WIFI...)

The antena is on top of a 60' tower , see this thread for more info about this , so theres realy nothing that can interfer with the signal now lol

Cards are not wifi card, my linksys and my d-link and my onboard networking MARVELL device are all 'normal' networking card that need a wire to be working :P

I am not using my linksys and my d-link at the same time, for now i have my d-link in the PCI slot, i've buy the LINKSYS first but it was not working so to be sure it was not the card that was bugged i bought another one , the d-link, to be sure of that... and the two of them are working in the same way, detecting my ip when i plug the wire in, but im not able to connect...

I've formated to be sure that drivers from my onboard networking MARVELL device (and anything else that could interfer or cause problem) are not installed, i've install my video card drivers, then my d-link drivers, and its the same problem...

Again, everything is working realy well if i plug the wire in a laptop that use XP PRO, the same OS i am using...

English is not my primary langage so forgive me for my wrong spelling

Hope things are more clear now :o

GooD

Another thing the need to be specify more clearly maybe is that in the first month of using, my internet connexion was working great with my onboard device, now that its getting worst day by day, i want to use another card but its not working

GooD

I got the answer from my ISP, they told me to try to use a router, otherwise that it was probably a hardware problem...

In other words they want me to buy a router and if its not working, thats still my problem... and i'll have to put my computer in repair for a networking problem that they will maybe not be able to reproduce without trying to use my 'WIFI' PPPOE connexion...

Do you think a router resolve this problem ???

Im so good to have the weirdest problems in the world

Do this:

Get internet working on your laptop and then go into command prompt (Start > Run > cmd). Type "ipconfig /all" (no quotes) and you'll see the IP configuration for the laptop. Leave it open and then plug in the desktop and wait for it to finish with the IP. Then also type "ipconfig /all" (no quotes) on the desktop and compare IPs between the laptop & desktop.

I have a feeling that your desktop isn't getting an IP from the ISP (for whatever reason) and is defaulting to Windows' private IP (169.x.x.x). If that's so, reply back and tell us.

Some ISPs will only allow one MAC (identifies the network card) per IP without waiting for a timer to expire or them resetting it, thus, switching from computer to computer often one works and the rest don't.

This can be solved with a router simply because the router would consistently be connected, looking to the ISP like it's one computer. Then internally the router would connect your multiple PCs to the internet.

GooD

That make sense Park_7677 !

Im at work for now but as soon as i get home im gonna check this out

Maybe you've put some ligth on my problem Thank your for that

I'll post some feedback as soon as i get home !

I'll probably buy a router tonite as i realy want to fix this out no mater the cost lol And even if for now i have only 1 computer at home, well if one day i've more i'll need a router anyway

profdlp

I'm betting that Park_7677 nailed it. :thumbup

Unless you pay extra for them, most ISP's give you one IP Address. The first computer which logs on grabs it and the rest are SOL. A router will do NAT (Network Address Translation), allowing multiple computers to share a single address.

GooD

What i found weird is that my ISP did not told me that... They know exactly my problem and if this is the case they should have told me this a long time ago lol

Well, maybe they're just dump



... To be continued tonite ...

GooD

:shakehead

I've done more test and im not about to resolve this problem it seems :thumbsdow

First, i've try my D-LINK networking card to see if i have a normal IP after the 'dectecting my ip' phase, and it was like 169.x.x.x.x so i figure out it was not receiving an IP and this is why this card was not working at all...

After that, i've buy a D-LINK router (DI-604) to see if it will get my problem fixed... After the installation :

good news :

-with both networking card (onboard MARVELL and PCI D-LINK) im able to configure the router, this mean that both card work correctly, or at least are able to comunicate with something lol

-my router is able to connect to the internet, i recieve an IP, DHCP is working so my computer is getting a IP from the router...

bad news :

Internet on my computer is still not working, well, it seems like its working, i can ping the 2 DNS ip that i can found in the router when he's connected to internet... I can also ping internet website like 'ping www.google.ca' and i got an answer MOST OF THE TIME, why most of the time ? because i've done more than one ping and sometimes i got 100% send/recieve rate, but i also sometimes got like 75%, 50%, and one time 25%... So it seems like its working, but its in bad shape...

In internet explorer i tried to hit www.google.ca and it was veryyyyyy longggg and i couldnt see anything load, i've made some close/open of IE and one time i've hit the website, the site was loading but the loading never ended... I mean, i could see the site, but the picture of 'google' was like 75% loaded and would not load anymore even if i wait...

I don't have the laptop anymore (its a laptop from work that i kinda 'stealed' for one day heh) so i was not able to test the connexion with my router from another computer... But im sure that if i get my laptop back at home it will work...

Weird thing : if i plug my onboard MARVELL device in the router, it seems that sometimes it makes it lose its internet connexion ! Sometimes The wan ligth are not flashing anymore on the router, even if i reset it wont connect again, until i unplug the rj45 wire from my MARVELL card... Then if i reset the router the ligths comes back and im able to connect... :wow2:

This problem did not happen with my D-LINK networking card in my test... So i believe my MARVELL device is realy f*cked-up... Man this is weird...

My ISP told me to try this : DOWNGRADE the version of firmware from 3.51 to 3.36, they told me it was a more stable version... but hey, i really dont think it will do any difference...

You guys are my last chance lol, i'll try the 'downgrade' version trick tonite but if it doesnt work the only thing i can do next on my own is to give my CPU back to where i've buy it (its still on the 1 year warranty) and see if they can find something...

I feel like if i was running after an invisible monkey, he's hidding and he laugh at me all the time :banghead:

GooD

Another thing is still in my mind, a simple question : do you think a bios could interfer in any way with this problem ? this is the only thing i know i've realy play with... Im back with 'default settings' in bios but if the bios can affect this problem i will try different bios versions, i use a beta version but its a version that is used by many users and its the version that was working the best with my hardware so i've keep it.

GooD

I've maybe found something...

http://www.dfi-street.com/forum/showthread.php?t=1198&page=1&pp=15&highlight=hal

This guy on DFI-Street seems to have resolve his LAN problems in windows ! He has updated his ACPI Uniprocessor drivers !

Device Manager >- Computer >- Expand >- ACPI Uniprocessor PC >- Right Click >- Update Driver >- Install from List... >- Dont search Let me Choose >- Choose Advanced Configuration and Power Interface (ACPI) PC.

ACPI Uniprocessor PC, Halaacpi.dll
Advanced Configuration and Power Interface (ACPI) PC, Halacpi.dll

2 differents dll, almost the same thing but one that work great with lan.

I'll try this out tonite to see if any of my 2 onboards lan device work now (I have a onboard Nvidia VIA lan device too but i always had problem with this one... the only one that was ok was the MARVELL)

I have nothing to lose now...

Park_7677

I hope that driver fixes your network card problem. I think your lost packets (ping is not 100% successful) is something wrong with your ISP. However, until your home network is stable we can't say that for sure.

Once the NIC works you should be able to ping your router and your other computers 100%. Does your router have the ability to ping from the web interface? I'm not familiar with the DI-604 web interface specifically, but is there a Diagnostics page or something similar? Doing that you could ping www.google.ca and bypass your faulty desktop NIC to see if the connection between the router and ISP is good.

GooD

For the ISP problems because of the 'ping www.google.ca' that not always work right... It was working great on a laptop... and my friend have this ISP and its working great too for him, my ISP told me im the first one to have that kind of problems

I did not noticed any kind of diagnostic tools in the router but i think there's some (http://www.dlink.com/products/?pid=452&sec=0) so i'll give it a try !

BTW : i've take more than 2 hours to look on DFI-Street forum and there's a lot of people having problems with lan and network related problems, not as big as mine but in the end many of them just not answered anymore... I've post a similar thread a this place and was not able to get any constructive answer from anyone

I must work now, but my head is away , at home trying to fix this problem maybe...

Feeling listened here is a good feeling , it makes my anger and desperate feelings go away

Thankx for the support ! SM

GooD

I write you now rigth from my computer (woot), but im connected in my MARVELL card and im not using the router (dahhh lol)

It must be one of the time that my MARVELL card manage to do something good with this load of problems...

I've found a place to ping a IP or a host from the router, and when im using the router and the router is connected to internet, its working... it said 'ping successful' after the process (post-back). So i guest everything is cool on the router side...

I've done some of the things that my seach lead me on today :

1) disabled windows firewall
2) put all my NIC on FULL DUPLEX 100 mode
3) downgrade my router firmware from 5.x to 3.36
4) install a new driver for computer (Device Manager >- Computer >- Expand >- ACPI Uniprocessor PC >- Right Click >- Update Driver >- Install from List... >- Dont search Let me Choose >- Choose Advanced Configuration and Power Interface (ACPI) PC.)

Nothing in this have resolve my problems. I still can't go on internet from my router. And the only NIC that can get me online sometimes is my MARVELL one. I've installed the Nvidia VIA onboard networking device too and give it a second try, i manage to connect (without router) and for 10 seconds it was working, after that i got d/c and could not connect anymore...

Side note : the 4 did something great to my computer i think, its weird but it seems to run a little 'faster' and 'smoother', on PC startup (windows loading). Maybe its just me... :rolleyes2

Park_7677

When you get your internet to work finally you should write down all the information (IP, subnet mask, gateway, DNS, etc). If you get in a situation where you need information, you'll have it.

Have you tried hooking up the router to the "decoder" box (what you described it as) with everything off? Hook everything up (Box <-> Router <-> PC) and make sure the power is off for at least a solid minute before restoring power.

There's no reason your setup shouldn't be working. It's just a matter of figuring out for what corky reason it's not.

GooD

Hahah, weird you tell me to do this, because that's what i did !

I took a screen short of 'ipconfig /all' when i was with my MARVELL and finaly got connected last nite. I was thinking it could be usefull to have that. Most of the time the problem with my MARVELL is that ligths are not flashing on the connector and on windows it says 'no network wire is connected' and the tray icon shows a red cross.

I'll post the screenshot here tonite if i manage to connect. Maybe you will see something that i don't see.

I'll also try the total POWER DOWN for 1 minutes... I've already try it but it was a while ago.

GooD

Ok, i did not tried the POWER DOWN thing for now.

But since i was in need to connect to internet friday night, i tried to connect with my MARVELL onboard device (without router) and it worked. And guest what ? Im still connected ! No d/c until now !!!! I did not close my computer as it was too good to be true and as i was wanting to play at WoW this week-end lol

Maybe it's just temporary, maybe when i'll close my CPU for a day it will come back... But its never have been that stable ! So i guest its a good thing I'll close my computer tonite and see if the problems comes back.

Its still weird that i can't use a router, or use another PCI NIC. But if it's working that's all i was asking for.

I'll post back tomorow to tell you if problems have come back after some hours of CPU power down.

GooD

:celebrate

It's been a week now, with some shutdown and reboot, and it's still working :bigggrin:

install a new driver for computer (Device Manager >- Computer >- Expand >- ACPI Uniprocessor PC >- Right Click >- Update Driver >- Install from List... >- Dont search Let me Choose >- Choose Advanced Configuration and Power Interface (ACPI) PC.)

It seems like this have realy solved my problems with my onboard NIC. it's really stable now. It's weird that it took some reboot (like 3) for the problem to get solved. Right after i did this trick it was not working, 2 reboot and it was not working either. Then a shotdown for the night and after that... IT'S WORKING

Thankx for your support Park_7677, you really help me to 'keep trying things' on this one

GooD

God dammit !

I wake this thread to give you some news about my situation.

It has been a while since my last post on that thread, the situation was okay and i was able to connect to the internet. I was having some occasionnal problems but switching from my NVIDIA NIC to my Marvell NIC (both onboard) always allowed me to be able to connect to internet within 5 mins.

But, my computer was running slower and slower and it was time for a FORMAT... i formated my computer and now i'm almost crying, the problem is BACK ! Whatever i do i can't manage to connect to the internet. I don't recieve a IP from my ISP when i plug the wire. It was working before the format so i'm very confuse. Since the format it seems like one of my on-board NIC do not work anymore (???), I plug the wire into it and there's no flashing and no connection or IP detection thing. On my MARVELL onboard NIC i have a IP Dectection but in the end it leads to a 169.**.*** IP (local ip) so its just not working.

I did everything i did last time to make it work... and its not working...

Im thinking about throwing that damn DFI BOARD on the wall. Im sure it's all related to my board for a weird reason. =/

I still have my 2 brand new NIC card that i plugged into a pci slot they both never worked, the only NIC that allowed me to connect to internet in the past was my 2 onboard NIC. Sometimes one of them was not working well and i was switching to the other one and so on...

I don't know why but im about 80% sure that if i change my MB for Asus A8N or something like that, this weird problem will go away. Unless one of you have a great idea, i guess that's the only thing i can do now :shakehead

GooD

That cannot be a MAC problem, since i was switching from one NIC to another all the time when i was having problems in the past.

That looks like a driver problems, but i installed every newest driver for everything. And that does not tell my why any brand new PCI NIC i tried does not work at all. The light is blinking but i've never been able connect to Internet when them.
