Network problems ?

[klw]

The router default setting will allow many computers to connect. Again, without having the computer in front of me, I'm at a lost.

 

It may be the network card. Can you purchase and install a PCI network card? I'm not saying that's the problem, so make sure you can take the card back.

Hi Tony -- The pc is only 3 weeks old max. It may be the card and if so I will contact the shop I bought it from.

 

I can't get it out of my head that it's a conflict somewhere but without the knowledge or experience I can't tackle it.

 

Pc B also has a satellite card ( which is classed as a lan I believe ) I wonder if it has anything to do with that ?

 

 

Thanks,

Okay let me rephrase if I may.

 

PC A (was working but no longer, no changes you're aware of)

PC B (currently working okay)

PC C (currently working okay)

 

Router Make/Model is: ??

 

PC A (what operating system)??

 

All computers are hard wired and none are using Wireless connections.

 

 

Please answer or correct any of this information.

Hi Advanced --- PC A you are correct.

B is currently ok

 

These 2 are both hard wired.

 

C is working ok and is connected wireless

 

 

Thanks,

I would like to re-ask a question that I asked at the beginning. Does pc A have to connect via a network? Under IE - tools - internet options - setup there is an option to to connect to broadband ( PPoE ) . Is this a direct connection that by passes the network card which seems to be the problem here ?

 

Does a pc need a network card to connect to the net ?

 

 

Thanks,

Just realised in response to my last post,my ISP setting on the netgear set up was " encapsulation = PPPoA " So that would rule out the broadband ( PPoE ) option as I seem to remember that my ISP doesen't support this.

[AdvancedSetup]

Okay it could be that for some reason on PC A that it needs authorization from you to enable the network card.

 

Yes, you need a network card enabled in order to gain access to the internet or other local computers.

 

Don't have a Vista PC here in front of me at the moment but will try to assist a little later on in the day when I get on one with Vista.

 

They made it a bit different getting to the actual hardware modification part on Vista as compared to XP.

 

Basically if it does not trust your local connection it will not enable it (might be the issue) why it would change though is unknown at this time.

Hi Advanced -- It seems to enable the lan ( in theory ) as when you right click on it later it gives you the then default option of disable. It then chuggs away and comes back as unidentified network.

 

Anyway I really appreciate all the help I have been getting,it's been a very stressful day so far.

 

I will give Netgear another try,they weren't very helpful last time as my router is a couple of years + in age.

 

Many thanks,

Just pleaded with the Netgear support guy and he reluctantly helped me out. When you try to ping the router it comes up with " transit failed error code 1231 " He diden't have any information on this and has referred me to my supplier which I will do in the morning as it's getting late here in the UK .

Found this just now http://www.andornot.com/about/developerblog/2007/05/virtual-pc-2007-and-nvidia-nforce.aspx

 

 

Even better maybe is this :-

the third page seems to offer some solutions, would appreciate someone taking a look if they get the time as my head is almost mush after all this.

 

The thread is July last year. I'd have thought it would have been sorted out by now,but who knows how long my pc has been sitting in a shop right ?

 

 

Kelvin .................

Well I would try this fix from Microsoft as it shouldn't bother the other systems either.

 

On PC A follow these instructions from Microsoft. If you're not sure of something then please ask us.

 

Windows Vista cannot obtain an IP address from certain routers or from certain non-Microsoft DHCP servers

 

Also... thought it was said or asked before. Do you have the Firewall disabled? What Antivirus application are you running on PC A ?

[klw]

Hi Advanced -- I only use the windows firewall which is enabled and AVG 7.5 from Grisoft for anti-virus. Thanks for the link. I will have a look tomorrow now and thanks for everything again.

Hi Advanced -- Just looking at the link you gave me,it's pretty advanced stuff for someone like me and it's littered with all sorts of warning messages. Not sure if I fancy tackling that. My vista was pre-loaded so would not be able to re-load it if anything went wrong or am I worrying too much ? I am sorely tempted to just take it back to the shop and tell them it isen't working and get it sorted or give me my money back. That still doesen't solve the problem though as all pc's are loaded with vista now and I'm just going to get the same thing if I had a replacement.

 

Any guidance is welcome.

[AdvancedSetup]

Well it's up to you. I can try to walk you through the change, or you could print out that article from Microsoft and take it with you to the shop and have them look at it.

 

Let us know.

[klw]

Hi Advanced -- That's a very kind gesture you offered me. I'd like to give it a try. Would you be able to do anything in real time ? I use skype ( voice only ) , ICQ , or MSN messenger or good old fashioned phone.

 

 

Many thanks,

or via this thread is fine as well.

[klw]

ERR You are not going to believe this but A has connecting to the web again. I know ! I know !

 

All that has happened is that B has been re-booted ( this pc is left running 24/7 as I have mentioned in an earlier post it has a sat. card ( which is listed as a lan )) and collects continuous data ). The electricity guys came knocking to say that the power had to be switched off for a short while for some local maintainence and after re-booting B , A now works.

 

A now " sees " B , C and the netgear router.

 

B now sees shared docs on C , the netgear router and has an internet gateway listed but nothing to say A is visible unless it is the internet gateway.

 

C doesen't see anyone else.

 

I would like them to be independant of 1 another i.e cant see each other,can anyone assist in tidying this up ?

Just to add A runs on vista , B runs on XP pro and C is windows 2000 based I believe.

[AdvancedSetup]

The easiest thing to do for them not to see each other is to do two things.

 

1. Make each computer a member of a different named WORKGROUP

(the name doesn't really matter just as long as each computer has a different name)

(no spaces in the name and no special characters)

 

2. Block via the firewall

 

3. You could also disable all file sharing if you want.

[Tony D]

I'm wondering if computer A was using an IP address that one of the other machines was using?

 

Can you go back and START/RUN/CMD and run ipconfig /all on each of the machines and note what IP address they have.

 

Also now that things are working, you can see how the following are supposed to work...

 

type in PING http://www.yahoo.com and then press the ENTER key.

 

also try PING 192.168.0.1

 

also try PING 212.135.1.36

[klw]

Hi Advanced -- Thanks for that, will amend when I get the chance, have a very busy schedule for a while and will let things be for now to catch up on a back log of stuff to do.

Hi Tony -- Will do tomorrow
