I've had a hair-pulling week trying to setup a couple of new wireless access points in the office.
Using the default of auto-channel selection on the AP, it selected channel 1 to be the cleanest channel. However, all our Dell Latitudes D610/D620/D630 did not manage to "connect" to the AP when using the internal wireless card.
My mobile phone could connect fine, so did an external adapter. Only the internal wireless didn't work.
I brought the AP back home, and it could connect flawlessly. I brought it back to the service center, and it worked too.
Then I tried changing the AP channel to some other channels and I was able to connect. Is there something with older Dell Latitudes with working on channel 1?
