which mini-PCI card to use? Bill Kearney 06-30-06

I'm going to replace the existing mini-PCI card in my laptop. The question
is, which new card to get?

The senao, ubiquiti sr2 and wistron cm9 cards all look like contenders.

Which ones perform the best all-round under XP? With netstumber? Under
linux? With Kismet?

I'd be using this just as a workstation, not as a router, access point or
anything else. I'd be starting with just the built-in antennae that have
U.fl cables but will eventually hack the case to allow for attaching an
external antenna. I see that at least one card has a single U.fl connector
so that'd hasten my addition of the external connector.

So whose card should I consider? Which ones are a pain to use and should be
avoided?

And no, I do not want a PCMCIA card or a USB dongle. They're fine ideas but
I'm interested in having the card remain built-in.

Thanks.

My personal favorite is the Atheros AR5004G -- solid, stable, low power
consumption, and excellent range. Another good choice is the Intel
2200BG.

Which maker and model laptop? (Your original message didn't appear on
Newsguy). Be advised that current IBM, HP, and possibly Compaq
laptops all have a "feature" which prevents MiniPCI cards that have
not been type certified with the specific laptop from working. The
BIOS detects the card and won't let the machine boot. There are
workarounds but most are no fun.

Current favorite card is Intel 2200BG with Proset 10.x.

Incidentally, MiniPCI cards are much like WinModem PCI cards. The
bulk of the "intelligence" is in the drivers and not in hardware on
the card. The card determines the RF performance, but the drivers
determine how well it deals with errors, PAD (packet assembly
disassembly), retransmissions, user control, and such. Find the best
driver, and then buy the card that goes with it.

The one for most ThinkPads is dead easy. Google "thinkpad no-1802".

That won't be a problem. It's a Toshiba laptop and it's already had several
different cards in it over time. All have worked just fine. The only thing
the 'genuine' toshiba card can provide is support for their on-board wifi
on/off switch. But it's a software switch that only their driver supports.
I've lived without that for quite a while. It's had a Dell 1300 Truemobile
(b/g) card in it for a while an Intel 802.11b before that. I just
discovered they hobbled the driver upgrade process by fiddling with the
setup.ini file. Damned driver install wouldn't work until I whacked some
values out of the ini file. Idiots, tough to say whether it's Dell or
Broadcom to blame. I'm sure there's enough to go 'round. I can now control
which antenna it favors, so now I can add that external pigtail.

> Current favorite card is Intel 2200BG with Proset 10.x.

The Proset stuff is what my wife's ultra-tiny Sony Vaio uses, can't recall
which model card. It does seem to work well. That and her machine gets
amazing battery life. Mine's a beast that doesn't usually last more than a
hour on batteries. So I'm less worried about power saving issues. I want
better WiFi use.

Hmmm, so are there any seriously negative issues with the drivers for the
Senao and Ubiquiti cards? I looked at those for their power capabilities.
I've never been particularly thrilled with how the inboard antennae on the
laptop have worked. Getting a card with the possibility of more power holds
some appeal.

I find it somewhat odd that the miniPCI cards would be described similarly
to a winmodem. Given it's a PCI bus you'd think the cards would be as
capable as a regular PCI card, certainly more than a PCMCIA slot device. Is
that not the case? Or, much like modems, does it vary from card to card?
