xp with vista n/w ing

[anurag_nagpal]

My first (formost) problem is:-
I have a Dual Core 3.4GHz PC with windows XP SP2 as OS. Other spec are RAM 1 GB, Intel Org 946ZIS Board onboard ethernet port. I have a Laptop HP Pavilion DV6345US with Windows Vista Home Premium as OS. Now I'd like to connect both of them using CAT cross cable (I have CAT 6 UTP 219888-7 05-24 cable). Well I tried to connect them, but failed. I can ping from Laptop to Desktop, but vice-versa is not taking place. Sharing I've done but not visible on other system. Pls help. I need every step to be explained, please don't mind.

My Second problem is:-
Along With the same setup I have Beetel ADSL2 Router Modem having ethernet port (I have BSNL broadband connection) and a Buffalo Wireless G Air station WHRHPG54 having one WLAN port and four ethernet ports. I can connect to internet via my Laptop wirelessly also I can connect to internet via ADSL2 modem using ethernet. But every time I've to change/switch cables. If i connect the o/p of R.modem to W/L router WAN port and CAT cable between any port of W/L Router and PC ethernet port, I can connect to internet through Laptop and PC is immuned to Internet (I know connection to both is not possible, I am talking about Laptop is not connecting, only PC is connecting).
If I connect o/p of R.Modem to any port of W/L Router and CAT cable between any other port of W/L Router and PC ethernet port, I can connect to internet via PC. Now the Laptop cannot locate any Wireless Network available.
So, I have to switch the cables every time as per use. Will you please help me out this situation i.e. I want the cables to be connected permanently and I'll use the PC or Laptop as per my convinience.

Is it possible to use same connection on both Pc and Laptop at a same time?

Thanks

I have just successfully configured my wireless network using the Netgear DG834Gv3 modem /accesspoint/ Router.
The networked PCs are the main desktop (XP SP2) and a DELL laptop(Vista Home basic)with builtin wireless adapter.
Folder/file sharing from the Vista lappy to the main Desktop(XP SP2) posed a little problem but after going through the Vista Help files and other articles, I got the right way and implemented it successfully.A seperate post will deal with it.
The basic setup is like this:
ADSL line after the splitter feeds the Netgear, with one of its LAN port directly connecting to the Main desktop ( using a normal cable - not a crossover cable).The Dell laptop(Vista) wirelessly connects to the Netgear.

I presume your final aim is to have such a setup as everybody would like it to be.The only difference in your case is, you have a seperate modem/router + accesspoint/ Router and there should be no problem in acheiving a wireless connectivity and network as in my case.

Your post is a little confusing but I presume that there is some conflict when using the modem/router + accesspoint/router which could have been avoided if you have used the modem/accesspoint/router(all in one) device.(No doubt your Buffalo is a widely acclaimed accesspoint/router)

You may have to reconfigure your modem/router to act only as a modem with other functions like PPPoE/DHCP/DNS/firewall taken care of by your Buffalo accesspoint/router.These are my first thoughts.

I have already downloaded your Buffalo's user manual and let me have the manufacturer/model number of your modem/router. If I could get its user manual from the internet, I may perhaps be able to analyse and suggest a solution.
I am not a networking expert but I have learnt quite a lot ( no help from Digiticians ) while successfully networking my PCs. ( I do not know honestly what is meant by razz but hope that fits in here)
