WiFi troubles

[Nezu]

Hello, for quite some time now, we've been having issues with our WiFi. Out of the four laptops and two towers connecting to the internet, only two laptops running Window 7 seem to connected regularly while the other two laptops are repeatedly being kicked off the WiFi for apparent reason what so ever. The two towers are connected through Ethernet cables. The router is only about four months old, having replaced it before hand for similar issues. Replacing the router had only seemed to work for about a month before the same issues reappeared. We are on a satellite internet connection in the middle of the desert so a clear view isn't an issue. There are power lines about 20 yards up and over the satellite dish but not all computers are being affected with this issue.

All the computers are being used for gaming through Steam and World of Warcraft. We've tried resetting the router, swapping out the cables, having the line professionally tested, bought a repeater unit, setting the router to reserve IP addresses for the computers, updating the routers Firmware and even moved closer to the access point. At this point, we're all ready to go with the beat it with a stick till it works option.

Model information
LinkSys E1000 Firmware Version 2.1.02
HP Pavilion DV6 Windows 7 Home Premium - Connected
ASUS N56D Windows 7 Home Premium - Random disconnects

The towers are custom builds that are older and running Windows XP Pro

There are 2 common causes of disconnects. DHCP lease issues so change the lease time to a very long time or put static in the PC. N/B/G compatible modes. The router will switch between b,g,n and sometimes drops connections in the process. The worst is B...you don't even have to be using B if the router sees anyone using it it convert to compatibility mode even if it is not using your router. Best is to use only N and then change the router support ONLY N. If you have to support G then you may be better off changing the router to support only G. It will run a little slower but it will not be switching.

Other than that it is most likely interference of some form. Could be anything and some devices are more affected than others.

Sorry for taking so long to reply.

Tried what you suggested but it ended up kicking the people who weren't having internet issues off the system. Bought a little adapter, gonna try that.
