Buffalo Router (WHR-HP-G54) only allows 1 wireless connection

This has been going on for quite a while. Whenever I try to connect a 2nd laptop to the wireless router, it won't connect unless I disconnect the wireless connection with the first laptop. When the 2nd laptop tries to connect it will say "Acquiring network address" for a long period of time. Sometimes it will connect, but will say "limited connectivity" and web pages won't load at all.

Is there a router setting that will permit more than one simultaneous wireless connection? The Buffalo documentation doesn't provide a solution for this problem.
 
Welcome to the forums. Please tell us what encryption you are using on the wireless router - acronyms like WPA, AES, WEP, WPA2-PSK are what you're looking for. The make and model of your wireless router will help as well. What you are describing is some kind of encryption mismatch between your router and your wireless clients. The security settings of your router must match EXACTLY what your clients are.

 
I think the DHCP is setup correctly. It's setup to use default information as when I first installed it. Do the settings below look OK?

I'm using WPA-PSK with a 26 character key. The router is a Buffalo Airstation Wireless LAN Access Point (WHR-HP-G54). I've had the router for 1.5 years. One of my laptops is wired to the router 95% of the time, so It's only recently that I noticed the problem when I started using wireless on both laptops.

Oh, and this happens on my cell phone too (T-mobile G1), will fail to connect unless it's the only device trying to connect to the router wirelessly.
 
You using few devices and there is the IP of the Router itself.

So right now there 5IPs assigned.

Look at the DHCP configuration and make sure that it can provide more than 5 IPs.
 
Are you using the stock firmware or have you replaced it with a thirdparty one?

I ask that because I use Tomato and it has an entry for how many IP's it can assign through DHCP and a seperate entry on a different page for how many wireless clients can connect at a time. If you are using the stock firmware I don't know if it has these seperate entries.

I read once about AOSS not being able to be used on multiple clients at a time. If you are using AOSS from the stock firmware you might want to check the book about it.

 
I'm using the stock firmware. I believe it has the same setup such that you can enter how many IP's it can assign through the DHCP. Right now it's setup for 64 devices, but like I mentioned earlier I am only using 3 devices.

AOSS is enabled, but I don't use it so it's not active.

Any more thoughts on what could be causing this problem?
 
The only other thing I can think would be to do a little troubleshooting to make sure it's not tied up in what security you are using.

1. Enable a software firewall on the pc that is wired to the router.

2. Lower the transmit power on your router to the lowest that you can still connect wireless from just a few feet away.

3. Disable all wireless security on the router and clients, making it just an open connection.

4. Now test with your wireless devices to see if you can get more than one on at a time.

Thanks for the suggestion. Going through those steps actually fixed my problem. Once I disabled the wireless security, all of the devices connected just fine. So then I re-enabled the same security as before and, miraculously, all of the devices were still able to connect simultaneously. So I don't know what caused the problem in the first place, but it appears the router security just needed a little reset.
