MX connectivity degraded with WPA2

#1 Postby uncle mark » Fri Jul 04, 2014 9:46 pm

I pulled out this old (circa 2001) Dell C600 laptop today to play around and do updates. Wireless connectivity was completely degraded; signal strength showed 1%, and pages wouldn't load. Between now and the last time I had this thing out I had a router fail; I replaced the router, rebuilt my LAN, and bumped my wireless encryption to WPA2 from the old WEP setup I used to have. With the old WEP connection, this old beater worked fine. After running into this diffuculty today, I set up the Guest network that my new router makes available, left it unencrypted (but hiding the SSID), and wireless connectivity is now good and strong. That's fine and dandy for here in my home, but if this thing were to have any usefulness anyplace else it needs to be able to use WPA2 encryption.

The wireless adapter in this thing is an equally old Realtek PCMCIA card. I suspect WPA2 encryption is beyond it's capabilities. I do, however, have a nearly new Linksys AE1200 USB adapter in my collection of miscellaneous stuff, so I gave it a shot. It's not even detected. My guess is that it requires USB2 (says so on the box), and I believe this old machine only has USB1.

Code: Select all

00:07.2 USB controller: Intel Corporation 82371AB/EB/MB PIIX4 USB (rev 01)


I'm open to thoughts or suggestions. This old beater is not worth putting much time or any money into, but if it no longer can connect wirelessly using today's standard level of encryption, then its usefulness has probably, finally come to an end. That would be a pity.

I've got an old Compaq Armada of that vintage - usb1 & pcmcia and the Netgear WG511u v2 (aka WAG511u) card works well connecting with WPA2. They're available for $15 or less in a number of places.

The TEW-421PC adapter found for < $10 at Tiger Direct is also reported to work well with the standard linux kernel drivers and supports wpa2, although I haven't tried that one.

I have an IBM Thinkpad T23 of similar specification that has only USB1. It works fine with a tiny adaptor that claims to be 'USB2'.

It's possible your adaptor uses a Broadcom BCM43xx chipset; if so, a look here might help:

On my T23. It works out of the box and is wireless N.

I know this is more towards using USB 1 hardware, But I have fould that moving my laptop by 6 inches I can increase the strength of my signal by 30%.

Very strange. This made no difference. Does this mean it has to be a software problem of some sort, or is there something else at the hardware level that would cause this?

Again, I had good speed with WEP; now, with my rebuilt network using WPA2, wireless connectivity is there but is so slow as to be worthless -- the plain Google search page takes forever to load. However, same hardware works great on an unencrypted guest connection.

Note that this is only apparent with this old Dell C600 running MX. All other wireless devises (laptop, Roku, cheapo tablet, etc.) are fine.

And now it's even stranger.

I'm now posting from MX-14.2 running live from the CD. WPA2 encryption is working fine and the browser performs adequately with the old RealTek card. With the new card (no idea about the chipset) it wouldn't connect at all -- but the new card actually would connect on the installed MX-14 original version, poorly with WPA2 and fine with no encryption.

These contraptions is just plain screwy.
