Hello,
A question for our resident WLAN technicians/expert. I have a WLAN at home which is access control restricted (based on MAC addressess) and WEP-key protected (my Access Point only has WEP).
My old laptop has a PCMCIA WLAN card and works fine withe Access Point. Now my new laptop has a built-in WLAN card and here the oddity begins. I get a connection to the AP and have good reception and everything. However, when I, let's say, want to load a.net there is no traffic between the new laptop and the AP; hence, the site loads very slowly or gets a timeout. These timeouts make it impossible for me to use SSH to my remote server.
I tested the laptop in a different WLAN (a public one), and it works flawlessly there. Thus, I don't think the built-in WLAN card is faulty.
It's really weird. Anyway, I am turning here to see if maybe some of you have an idea what the trouble might be.

Are you certain you've connected to your own access point? Did you enter the login information for your own access point?
Maybe your own AP simply doesn't show up and you've been surfing through a neighbour's WLAN all this time...!
That might explain both why it's slow (weak signal) and why there doesn't seem to be any traffic through your AP...

I'm not using WLAN myself at this point, but in that case it looks a lot as if reception is very poor. This leads to automatic down-scaling of the connection speed and in severe cases can lead to spurious or altogether interrupted data transfer.
Besides a bad antenna or defective RF components in your access point I would expect interference from other WLAN networks or other RF sources being a potential source of your problems. Even the firmware of your access point could cause those problems, so you should check if an update is available.

Why have you locked it to your MAC address? I never felt the need to do that. I created a 13 word WEP key and that works fine. You also have to make certain that your DHCP is enabled, to assign the correct IP address.

Check on your network authentication protocol. It could be open, shared, WEP, etc. They all have to match for the wireless to work. I have two laptops, plus a PDA, that use wireless. I had to make certain the security protocols matched all devices.

This was my first thought.
