I have the Netgear MA401 card working nicely on my laptop but it's going slow.

The fastest time I can get it to transfer to and from my windows xp laptop is around 200kb per second, so a 1MB file takes 5 seconds.

When the system boots and initializes the card, it says 11mb/s speed. I'm no more than 10 feet from my good 802.11b/g router which on my other laptop with a 802.11g card, works nicely. I tried to install dsl on my other laptop, thinking that the problem might be the laptop, but its the exact issue. Also, I when I go farther from the router, ie. downstairs, or in the backyard, the speed DOES NOT slow down. It stays the same. So this tells me that it's not bad signal quality to begin with.

I think it should be able to do at least 750kb per second (that's only 5mbps speed) but anything faster would be nice.

Please help if you have any ideas.

How are you transferring these files?

If it's on some media, does that drive have dma enabled?

The transfer is over the network and from Hard drive to hard drive. I've used different hard drives for the laptop and have tried the transfer to two different windows machines, and 200kb is my top speed. Never over and never under.

I don't know what else it could be other than the card. When i connect a usb flash drive on the linux box, the transfer rate is very fast, that tells me it's not that laptops hard drive.

If you suspect the network card then post the results of:

ifconfig eth0

Look at errors, dropped, overruns etc.

Hope you didn't buy one of those refurbished cards.

I have no problems with my 401.

OK, here's my results...

Link encap: Ethernet HWaddr *********
inet addr: 192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

When i run iwconfig, on the third line it reads:
Bit Rate=11Mb/s Tx-Power=15 dBm Sensitivity:1/3

Please help. It looks like there are some errors...is that the issue, and if so, what can I do?
