two pc sharing same router with rj45

[matabhaine]

i have read posts but sorry techno fear has got the better of me, i have two pc's, one upstairs and one downstairs, the one downstairs is online with virgin media, i have it running through a router via a rj45 cable, the other pc is running through a rj45 cable also, i cannot set up the pc upstairs it doesnt recognise the pc upstairs, so if any one can nudge me in the right direction, a faq or earlier post i would appreciate it, i was reading about setting up both pc's on the same workgroup, but it starts asking for disks and running on all pc's thats when i bailed out and decided to beg for some help, thanx

Hi Matabhaine

 

From what you say it sounds like you using XP on both your computers!

 

but because their are slight differences between XP and Vista could you please tell us what operating system you are using so as to avoid any confusion?

 

Thanks

just spent ages getting back on line, tried to set it up, changed my ip address and could not connect, set it back to find ip automatically and thank goodness i got my signal back, any way iam using to separate copies of xp home basic, it is a tp-link TL-WR340G 54M wirless router but i am trying to use rj45 cables, i manage to get the pc downstairs through the router and the upstairs one appears on the downstairs one and says its connected but the upstairs pc still wont go online, hope this helps with clarifying my problem thanx

What I would like to do is clear up exactly what is is that you want to do that you cannot do. If I understand you correctly, all you want to do is be able to connect to the internet from both computers using the same router. Is that Correct?

 

Or, are you trying to network these two machines?

If the upstairs PC can be seen in the network from the downstairs PC then the local network settings must be correct, ie your upstairs PC has an IP address and subnet mask.

 

Perhaps the DNS and/or Default Gateway are not correct.

 

On the upstairs PC, make sure all the network settings are set to Automatic - that includes DNS and Default Gateway.

 

Can you click Start>Run and type cmd, then press enter.

 

A black box will appear, type ipconfig /all, then press enter.

 

Lots of information will be listed. You are looking for the info for the Local Area Adapter.

 

Look for the IP Address, then the DNS Servers and Default Gateway - post back that information.
