Att Yahoo web mail does use pop3 and SMTP servers. But I use it because I can see it better and it's better formatted than evolution or tb which I have installed and set up. The seeing issue is overriding for me-:))

Well, anyway I think knetworkmanager is the same thing.

I'm beginning to think not. I just posted again on erratic behavior using firefox and web mail that covered the intermittent and stange
operation. Chris suggested I install
adblock plus which I did and things a little better but mouse pointer froze again so I ran top which I have many times on this same issue.  This time it showed that firefox bin was taking up 98*% of the cpu and I've never seen it above the 1-20% range.
It's now settled down to that range and no mouse freeze and typing shows up as I hit the keys. I've heard the firefox is a memory hog but have never seen cpu usage for it that high. Haven't posted a follow up on the high cpu usage but it most likely is the cause. I'm also beginning to think my lost connections are caused by not having a persistent connection and it is dropped when the browser is idle. I don't think I've done that since my dialup days but will check in /etc to see if I can fine something is pppoe or firefoxrc that may allow me to do that. My thoughts anyway.

The NIC card is always disconnected in normal use when using the machine as wireless in the other room. Nm must have set it up as I don't remember everdoing so. I think I should quit procastinating and rm netwrok magager as NoOp suggested and actually intended to but haven't yet.
Strange, I just again checked /etc/network/interfaces and nm and they both only showed a wireless connection. I had commented out auto wlan0 which was still there but another on was added at the bottom of the file. Also, the last time I looked at 2wire config early this morning, it has wireless disabled and wired enabled. Now it's OK again after resetting nm and restarting networking. If nm is causing all this I want to rid myself of it and can see NoOp's distaste for it. This is really wild for me and never noticed it before on gutsy 32bit. WOW!
