Title: All internet connections are not the same...
Post by: gigabytecoin on April 04, 2011, 06:49:36 PM
I made a post a week or two back asking what your number of connections on the bitcoin client was showing.

Now I have something quite odd to share with you.

I have ~5 dynamic IP addresses allocated to my apartment.

I was getting ~40 connections max after a few weeks with my windows 7 computer plugged directly into the wall.

Unplug that same computer, and hook it to the internet via Wifi and I have been seeing a steady 8 connections for the last few days. 8 seems to be it's limit for some reason..? Anyone know why?

I ran bitcoin on an ubuntu box in the same apartment and it immediately jumped to 60 or 70 connections within minutes of starting it up.

So I can safely say, that all internet connections (when it comes to bitcoin) are not treated equally.

The real question is why?

I can connect to the same number of seeders whether I download a torrent through my windows computer or my ubuntu box.

Are you NAT'd on wifi and not ethernet possibly?

Aren't we all?

Did you point your external IP:8333 into your internal W7 IP:8333 for both ethernet and wifi?

Stopping at 8 connections implies that inbound connections are being rejected.  If all you did was add the wifi router into the mix, it's probably configured by default to deny incoming connections on unknown ports.

creighto is right. routers come with ports closed by default(with maybe couple of exeptions - dns, www, UPnP). I just tried it on one of my machines. If I use wireless router with default config, I get steady 8 connections, but if I enable port forwarding, number of connections encreases to 32

You were correct!

It was because I did not forward the ports properly.

However that still leaves me with a question about platforms.

Why does bitcoin on linux jump up to 60-70 connections within minutes, and bitcoin on windows 7 takes weeks to get up to 30-40?

Because Windoze sucks?

I can't help you here, as I don't use Windoze if I have a choice.
