#1628 — choice of wireless adapter

I know this is a FAQ, but despite guidance, I've only met frustration. 

I had a Netgear 802.11b which worked after I used the orinoco driver,
but then it began to drop the connection, requiring reboots.

I looked for a PCI card that would work with Debian out of the box
(kernel driver), and purchased a Gigabyte Wireless 802.11G Lan
Pci because it was highly recommended. Unfortunately the information was
old, and this model no longer works at all.

It seems the cards that work well are ones with RaLink chipsets. Do I
understand that the RaLink chip is on the Rosewill cards? I'm going to
try a Rosewill RNX-300x. Is this supported by a kernel module, or do I
have to install a RaLink driver?

I just bought a Rosewill RNX-N150PCe which uses the Atheros driver.
It does not work out of the box. Previously I bought an Asus card
which used a Ralink/Realtek driver and it did not work either.

According to what I have read, both cards were properly recognized
and the correct drivers were installed, but wicd did not see
any networks. All of my old wireless G cards work fine.

Good luck.

Did you try changing the interface? There's a stupid udev script which
associate an interface with the MAC address, so if you had wlan0, when
you use a different card it will become wlan1. Wicd is still trying to
use wlan0, so you don't see any networks. I get burned by this
idiocy when I clone a system to another computer. See
/lib/udev/rules.d/*persistent*.

Great idea. Now I remember that I was stung by and eth0/eth1 mixup
in just this same way. OK, I just booted up one of my problem
machines and, just as you suspected, iwconfig revealed I had
wlan1. I deleted the entries in /etc/udev/rules.d/70-persistent-net.rules
and rebooted the machine. Now I have wlan0 and wicd works.

Thank you very much.

I installed the Rosewill RNX-N300x, and before I knew that there was
already a staging module (rt2860sta) available in my kernel I downloaded
a staging driver for it and compiled it. It works fine (but see below).

I had to modify my interfaces file because the interface for this driver
is ra0. Then I had tell wicd Preferences that that was this name of the
interface. Until then, wicd-gui showed no network connections.

One anomaly is that wicd-gui reports signal strengh of only 34% (it is
now only a few feet from my router, but will end up at some
distance). Another AP in the building is 100%.  No idea why the strengh
is so low. However, when I hover my mouse over the wicd icon on my
desktop it says it is connected at 86% strength. Also the icon has now
acquired a vertical green stripe on its right, and I've no idea what
it means.
