Think I finally nailed the problem; finally found an option for the thing's firewall regulation that seems to have done the trick.

It seems to have been doing some filtering of TCP and UDP connections... disabling those options seems to have solved my disconnect issue. Will update if this turns out to not be the case, otherwise... Thanks for helping, guys!

Doing a few tests to see. Will edit this post with the results as they happen.

In each, I'm going to connect, tab through the MUD's intro screens, then wait until it registers a disconnect.

First trial: 11'50".
Second trial: 3'32".
Third trial: 8'10"
Fourth trial: 2'19".
#5: 8'41"

So you see why I'm boggled.

I've been trying to quantify it (which is why I haven't been answering that question), but it's... kinda unpredictable, honestly.

Sometimes it goes out within a couple minutes of switching, other times it's made it ten or so...

I don't see how the router could possibly know which window is active.

Can you give a figure for the time it takes to drop out?

I'll point out that the one you linked is not precisely the same model as mine; you're looking at what appears to be mine, with an added dual-band feature, while mine is the plain single-band version...


Still testing some stuff. But at this point, I AM pretty sure it's the router, so... Hmm.

The odd thing is... The MUD stays connected much longer if I'm actually looking at it. If I switch windows, it drops faster... Odd...

Maybe that's the router prioritizing active traffic over the "idle" traffic?

The D-link DIR-615 router? I'm not finding any reviews with the keyword "timeout."

(I realize that's different from what I put in the OP, but the Amazon search pointed out that it's listed under a different title than "N 300".)

If you go to Amazon web site, search for your router, expand to "see all reviews" and look for "timeout" you see some interesting comments. Pretty much what I experienced with my earlier router. Also read some of the other reviews.

Two minutes I believe. I looked it up when I amended the "connection problems" page.

I think it would be independent of what you are doing at the time.

So I suppose if you sit there doing nothing, you would get a timeout (detection) with a granularity of two minutes (not necessarily from when you last typed something).

Hmm...


What is the interval on the tcp_keepalives?

And does that interval begin from the last command sent from that world, or does it follow its own internal timer irrespective of user input?

Now that you get the "disconnect by itself" behaviour, can you work out a pattern? Surely it isn't random? There must be some sort of time limit.

That sounds likely. If you're getting disconnected even with keepalives, it sounds like a bigger issue than simply dropping idle connections... If I were you, I'd explore the router firmware to see if there's anything relevant.

Hrm, it seems to be acting up again... except now, it does disconnect by itself.

What I think may be happening now is that the keepalive is causing it to recognize the disconnect...


Hmm...

Looks like keepalives is doing the trick, now that I actually have it going.

Thanks for the time... This is why I really like MUSHclient; the support is spectacular! Even over minor issues like this.
