Iwconfig reports many errors
 
Having a strange problem. I have one laptop running under Windows and another under Linux. I can access and surf the internet on both computers. But the Linux laptop is painfully slow.

If I ping my gateway the Windows lappy does in in 1 ms but the Linux in 20ms. iwconfig reports errors under Rx invalid crypt, tx excessive retries and huge numbers under invalid misc, and nothing on the rest.

The router is encrypted with WEP and iwconfig reports the correct key.

Any advice?

Not Encryption
 
I turned off encryption on my router and rebooted then reconnected the NIC.

Same issue. Nothing changed.

Have you confirmed that you are using the proper driver?

You forgot to say:
1. what wireless card on laptop do you use?
2. What wireless driver do you use?
3. Is IPv6 enabled?
4. What is encryption method?

Thanks

As I said above, I turned encryption off. So that means encryption method of none.

IPv6 enabled? No.

Card: Using a Marvell 8386 with the latest drivers from the Marvell website. 9.7.

Can you post the link to the page you downloaded the driver from as I'm not finding one on marvell's site specifically for your card. Also what distro are you using as well as what is the laptop make/model. It looks like the libertas driver is the correct driver for your hardware, but I'm finding some "distro-specific" instructions for the firmware.

Finally depending on the distro and hardware ndiswrapper, which uses windows drivers, is SOMETIMES a good option.

Sorry, that was a typo on my part. It's the Marvell 8686 and it's this driver which is the one specially mentioned by the computer manufacture.

http://extranet.marvell.com/drivers/...o?driverId=203

However, it is possible that the manufactures website is out of date. I have an e-mail into customer support there and perhaps (just perhaps) they might respond.

What is your distro?

What is the output of
Code:
lsmod
or
Code:
sudo lsmod
depending on your distro. Also give the output of
Code:
lspci
