Solved: laptop only has 1 Antennal wire?
is this normal?

Acer Aspire 5733 connects at 65Mbps over wireless-N and only has 1 ariel/antenna internally (but has 2 ports)...does this effect range?

even my 6 year old wireless-G laptop has 2 ariels

thanks

Antennas are usually cut to the required length that is
required for the frequencies they operate on.
So range would more be determined by the power of the
reciever/transmitter hardware.
Having only one antenna should not really affect your range.
Your wireless G laptop may have also had a wireless/bluetooth
combo card/hardware that required another antenna.

thanks leroys1000

there was no bluetooth or anything other than wireless-G on old laptop.. its the first laptop ive seen with 1 ariel... and ive been inside many!!

my other sister has an old cheap celeron laptop and it has 2 wires and connects at 300Mbps...

2 be honest if it doesnt affect range/signal quality in rooms then im not so bothered about the speed

Some smaller wireless cards use an antenna printed on the circuit board.
Looks kind of like a square zigzag pattern made out of the traces.

ahh - it may have one as a 2nd one because it works in 40mHz mode (135Mbps)...you would think it wouldnt if it had just 1 ariel am i right?

It's running at 40 because you are connected to wireless N.
If you connect to G it will be slower.

I have the same laptop and am about to swap the wireless card out for an Intel Ultimate N 6300 and that requires 3 antenna. I'm gonna fit an additional 2. I will let you know the results with and without 3 antenna once it is setup.

Tested with a Cisco/Linksys E4200 router and the Acer Aspire 5733 (Using Atheros AR5B125).

High Signal Area

2 antenna = 6.7 MiB/s RX 6.5 MiB/s TX 0.9/2.3/1.4
1 antenna = 6.6 MiB/s RX 6.0 MiB/s TX 0.9/2.7/1.1

Low Signal Area

2 antenna = 4.5 MiB/s RX 2.8 MiB/s TX 1.0/51.9/3.9
1 antenna = 2.8 MiB/s RX 2.7 MiB/s TX 1.0/26.5/2.1

The transfer rates are average throughput using SAMBA and measured with Netlimiter. The numbers at the end are the min/max/avg for 100 ICMP packets between the laptop and the router.

The new Intel Ultimate-N 6300 does 30 MiB/s RX/TX actual throughput.

If you are thinking about adding an antenna or replacing the card then these might be useful.

The main difference is that the speed was greater at longer range. I don't know if it increased the range outright though.
