OT: Intel Wireless WiFi 4965AGN stuck at 54.0 Mbps

[smlunatick]

Does anyone know why a HP Compaq 6820s laptop that has an Intel Wireless WiFi
4965AGN mini-PCI adapter be constantly stuck at 54.0 Mbps when within 3 feet
of the 11n router? I have followed the recommendations of Intel and set the
router to WPA(2) with AES encryption. The card was warranted replaced and I
have tried both the Intel Pro management software and Wireless Zero
Configuration. Neither will get the Intel card to exceed the 54.0 Mbps
speeds. The router is a TRENDnet TEW-631BRP and I know that the 802.11n
signals are working since there is a D-Link RangeBoost N (DWA-142) USB adapter
two floors up (router in the basement, D-Link on the second story of the home)
which is connecting at greater than 200Mbps.


BTW: Does anyone know if the number of wires connected to this model of
mini-PCI wireless card is important? This one only has two connected to
"port" 1 and 3. One is completely "non-existant" / not connected (port2.) I
fear that HP has lamed this adapter since I found several references that this
card needs all antennas connected but it seems that there is only one in this
HP.

?? What do you call ports or wires - the antenna connection points?
For N mode you need to connect all 3.

The small internal mini-PCI adapter has three snap on connector but only has 2
wires connected. I did not see any "third" wire for the middle connection.

Too bad. Ask HP how to connect the 3rd antenna.
Temporarily you can try and connect any suitable external antenna.

Can you guide me to a suitable antenna or are you confusing an
internal mini-PCI laptop wireless adapter with a standard PCI /
cardbus card.

Mini-PCI adapter is completely internal to the laptop with the wires
goin to a connector that looks like a pants snap fastoner.

When I checked the product page on the Intel site, it said the mini-pci
design in question, is compatible with two or three antenna systems.
It could be, that whatever software/firmware controls the device,
can be configured to not use the third antenna.

From product brief -

"On-board diversity support for systems designed with two or three antennas"

For Wireless_N, there are various options for how the antennas can be
handled. For example, according to the naming conventions here, your card
might have options for 2x3:2 or 2x2:2. Meaning the third antenna connector
might be receive only, for example. (If it was my card, I might try
tracing down the chip numbers on the card, and see if there are specs
that identify how many radios the thing has and so on.)

The fact that you're running at 54, suggests it isn't even in "N" mode
right now. The user guide from the Intel site, lists this.

"Supported Data Rates

* 802.11g: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54
* 802.11b: 1, 2, 5.5, and 11
* 802.11a: 6, 9, 12, 18, 24, 36, 48, and 54
* 802.11n: 300, 270, 243, 240, 180, 150, 144, 135, 130, 120, 117, 115.5,

Yes, I'm talking about the 4965 AGN mini-PCI express card with 3 tiny snap
connectors.
All 3 connectors should be connected to antennas for best results in N mode.
Sorry I don't know where to buy the antennas, I've used whatever we have in
our lab.
AFAIK almost any antenna will work, it 's much better than leave it
unconnected.

Then can anyone confirm that the HP Compaq 6820s comes with three
antenna wires? The unit I dealing witth only have two wires with the
middle connection "empty." Does this mean the laptop has a
manufacturing defect??
