Wlan Access Point Problems

Sun Jul 23, 2006 2:25 pm

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...

No, it is my own AP. I entered the code and I see the MAC address of the laptops on the AP's admin page.

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.

Are you by any chance using the default ID name for your signal?

The signal is strong and excellent.

I updated the WLAN card's firmware; the AP has the latest firmware.

You mean the default name of the AP? Nope ... I gave birth to a really creative name. *g*

There is some rumour that the built-in Intel WLAN chipset does have hickups with some Access Points. Maybe it's this.

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.

As an added security feature.

I have fixed IPs and don't use DHCP.

I will test the laptop again in a different environment to see if it's not the WLAN NIC.

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.

Checked, re-checked, and checked again.  wink  This was my first thought.

I found an article in Intel's knowledge base http://support.intel.com/support/wireless/wlan/sb/cs-006205.htm that may help.

Just for reference purposes I have an Intel PRO/Wireless 3945ABG NIC and a Netgear WG602 AP.
