You should also download the latest client utilitiy software. I found
almost the same results. After upgrading my PCI 3400 firmware, the client
utilities also gave me strange results.

> I came across a weird problem while I was installing the wireless service
> to a customer.
> I set up a PCI 340 card and connected it to a 6 dbi patch wall mount
> antenna using low loss cable. Everything, card, cable and antenna are from
> Cisco. On the other hand, there is a perfect line of sight between the
> antenna at the customer´s site and our 12 dBi omni 700 meters away.
> Here is a brief description of the problem:
> Link status meter showed 100% signal quality and 46% signal strength,
> however ping tests failed. 100% packet loss on all probes.
> So I upgraded the card firmware to version 4.25.5 and LSM then showed 20%
> signal quality and only 1% signal strength. Under these conditions there
> were a few successful ping tests. So, I slowed down the speed to 1 Mbps.
> ACU instead of letting the card assign it dynamically and found that
> improved a lot, for example ftp transfer rates of 60 Kbps. All this at
> approx. 20 % signal quality and 1 or 2 % signal strength !
> The problem I wasn´t able to resolve is that when the signal strength and
> quality (randomly) improve (say 30% or more signal strength and 40% or
> signal quality) data transfer stops. Absolutely no single bit comes or
> out. I tried changing some settings in ACU (such as speed and radio power)
> but nothing improved.
> Does anyone have a clue why this may be happening?
> Good transfer rates with poor quality and strength and no transfer at all
> with better quality and strength? I have no explanation for this.
