There is also a version 2.0 and 3.0 of the W722N out there that does not use the friendly Atheros chip--it's got some Realtek chip instead that I don't think has a driver in the kernel yet, I believe. So be very careful of what you're getting.

Indeed. I have 2 WN822N dongles. The first one, v2, has Atheros chip and works well with just firmware-atheros required. The second one, v4, I bought because the first one worked so well, only to be disappointed that it contains a Realtek chip which only works after building a driver from Github and is not 100% reliable even then.

they could a pain for Linux, for sure,, so far the WiFi dongles, that I've obtained,
have worked on some of the later kernels, but I've not tested them on the very latest kernels.

the one that I've been using,, the TL-WN721n is working okay on my Kde Neon machine,
& which is one of the few desktops, that I've recently obtained :happy:

Thanks for these good posts. There seems to be little knowledge on the web about wifi compatability especially the changes in chipsets.
I have resolved at least part of my problem with my built-in wifi card. Some of these older ThinkPads are restricted in the use of installing other wifi cards giving an error message when trying to boot with them ie; "1802 Unauthorized network card is plugged in. Power off and remove the Mini PCI network card." As described here> http://thinkwiki.org/wiki/Problem_with_ ... twork_card I have a Broadcom wifi card that I installed and received the Error 1802 message, so I used the CMOS work-around described here> https://command-tab.com/2006/02/26/thin ... error-fix/ and was able to use this Broadcom Card. I used the files from that website as well.
Anyways, like I said, part of the problem is fixed as the Broadcom card is much more stable because I no longer keep getting constantly disconnected from the network as I was with the Intel ipw2200 card that came with the ThinkPad. I don't know if it's a problem with the Intel card or the drivers for it.
I still have weak signal issues though and so I am still interested in going with a good Dongle. Apparently this ThinkPad X40 must have crummy antennas in it. So I am now looking specifically for dongles that have a cable so that I can place the antennas remotely for best reception, with a good compatible chipset of course....Thanks Again I am learning a lot! ;)
The card that I am now running is

Code: Select all

Card-2: Broadcom Limited BCM4318 [AirForce One 54g] 802.11g Wireless LAN 
           driver: b43-pci-bridge 
           IF-ID-1: wlan0 state: up mac: <filter>

A USB extension cable costs a couple of bucks.

You are rocking a pretty old Thinkpad. These things are hard to kill :) If you shop around you might be able to find a used Thinkpad for not much more than you invest in a wifi dongle. I got a T400 for $35 on ebay. It needed a little work but nothing too serious. Many of the used Thinkpads 10 years or less old have pretty solid wifi support. Most of mine use the iwlwifi driver and have solid wifi.

Hello Sunrat,
A USB extension cable costs a couple of bucks.
That is very true. I might even have one somewhere.

:cool: :happy: Thank you I'll check them out. This X40 was a gift from an older Neighbor lady in like-new condition although the battery has only %23 life left since it sat around for so long.

And thanks to you too Joe good to know.
The other links that have been posted on this subject I have found very informative and useful too.
Cheers!

Sometimes the disconnect issues can be solved by setting a conf file for the iwlwifi driver that disables the automatic power savings. Usually doing a web search will show the procedure for your particular card.
