I'm 100% sure You'll see improved performance with a faster CPU.

I have good experience with an Intel Pentium M solution with 1.8GHz.

Do a search on this site and you'll end up with a lot of information regarding this issue.

Good luck!

You can of course allow all IP's from your client network and deny all others.

Or you can enable SMTP Auth:

We've had the same problem in some of our Access Points. When we changed the radiocard with a new one (same brand, same model) the problem disappeared.

EIRP should be about 30dBm. If it's a 2.4GHz link the RF should be about -60 and with a 5.6GHz link the RF should be about -66.

Unless I've made some bad calculations, this should not be a too strong signal.

But you could try sifferent TX-values. What is your ACK-setting?
