Different wireless devices reacting differently to wireless signal!?

besty

Hi,

I'm having some trouble with my wireless broadband at home.

A couple of days ago, I changed from Eircom to BT. I changed the modem/router and am now having some problems. The Modem is connected to the downstairs PC but there is no internet signal (wired) on that computer.

Upstairs, I have another PC which uses a USB wireless receiver. The internet on this computer works fine.

My dad's laptop picks up the signal without any problems.

My laptop will not connect to the signal properly. The connection is an "Automatic Private Address" and it is not assigned by DHCP. Therefore, my laptop will not connect to the internet although it shows the wireless signal.

I hope I have phrased this clearly and would really appreciate some help!

Thanks

Check the passphrase is entered correctly. You are not getting authenticated by the security on the router. Turn off the security to test to see if you can connect then you'll know.

Why doe the machine that the modem is connected to not have any signal??? WTF

OK, heres where I stand now.

My wireless on the laptop still doesnt work. It's still an Automatic Private Address - no Default Gateway is assigned. When I connect via ethernet to the router however, it works fine.

I installed the USB/Ethernet converter on the PC connected to the router directly and it will now connect to the internet.

The wireless signal will no longer pick up the router and I can no longer connect to the signal with the upstairs computer.

The lights which are flashing on the modem/router are the "internet" one and the lan port number 1. This is the port used to connect to the downstairs PC.

Any bright ideas from anyone by any chance?

Im confused - why cant you just set both the router and your laptop up to use dhcp? Once that is sorted then you can try messing arround with fixed IP's.

A couple of things.

Do you still have the eircom modem, or did you send it back? If you still have it, put it back in place - it will work just fine with BT, you may have to change the PPPoE userame and password on it.

If you dont have the old router, the first troubleshooting test is to disable encryption on the router and the wireless client. If you still can't connect with any of the wireless devices, assume the router isn't working. If you can connect with some of the wireess devices, but not others, assume the router is okay, and the the non-connecting devices are the problem. This sill at least allow you to focus your troubleshooting in the right direction.
