I have a desktop PC with RJ45 and two laptops with WiFi hardware and RJ45 in each.
This is for connecting two types of network {Ethernet (using RJ45) and WLAN (using WiFi)}.

All this trouble is for playing LAN games with friends.

What I have done till now :
-> Connected LAN wire between My PC to Laptop1 (Worked FINE, both of us can join each others game server)
-> Created an Ad-Hoc wireless access point in Laptop1 and connected another Laptop2 through it with WiFi.
I was thinking to make Laptop1 as central server for game.
Here problem STARTS - Either My PC or Laptop2 can gets able to connect to Laptop1.
That means even though Laptop1 is a central server for game and My PC and Laptop2 are connected to it with different mediums then also three of us can't play games in LAN.
-> Tried above process in reverse order i.e. Laptop1-Laptop2 and then MY PC.

I have a Switch with 6 LAN PORTS (not LAN to WiFi). But trying to implement kind of Hybrid network , but didn't worked .
Is it impossible to connect this type of networks with above mentioned H/W or I did some mistakes?

I can buy WiFi H/W for MY PC (but not willing to).
Please mention WiFi with internal antenna or EXTERNAL antenna will be better for desktop PC of same dbi (don't mention product or company name).
Purpose - Indore gaming within 50 meter.
How much antenna power in dbi is sufficient for this range.


Thanks to all of you I alter the title to:
Wireless LAN / WLAN party advice

You have more than one question.
You are asking:
1. How to set up an Ad-Hoc network.
2. Make a bridge from Internet into a local network.
3. Do this without using a router like every body else does.

Is this for you a puzzle to solve or do you want a solution?

In general, hybrid networks are hard to do.

As for gaming, at a LAN party the common thing is everybody get in with a wired connection via a Modem/Router unit. Wireless is said to be not as good and direct wired tRJ45 Ethernet.

Otherwise if everybody does Wireless in the same room you can have a good party. However, any player 50 meters away is at a slight disadvantage.

Have you read this?
http://www.wikihow.com/Host-a-LAN-PartyTake a look at this site.
http://support.microsoft.com/kb/299540

It says something about metric value of network adapters. Also says wired network gets preference over wireless network.
Others experts also saying about modification in metric value (Automatic to manual value) to connect WLAN and LAN at same time.

If anyone having detail knowledge on this topic please share.
If you suggest me to go with this, i will give it a try.
