Hi,
I connect to a wireless homenetwork. I recently port forwarded bitTorrent to port 60000 on the BT Voyager 205. I found that the connection kept starting and stopping in short bursts. This made browsing impossible and I kept losing my MSN Messenger connetion. iTunes couldn't download a podcast before it dropped. I then forwarded the relavent ports for MSN Messenger (1863, 6891-6901) and iTunes (3869) and it seemed that everything worked fine therafter. However, a few days later I'm still having the same connection problem. I know that bitTorrent can cause a connection to drop if the download is too fast but this is happening at slow donwload speeds <30Kb.
Do you think I have messed up the settings or that this is connection problem is unrelated to bitTorrent. I know I forwarded the ports correctly but could this have anything to do with my problems? I have no firewall...

Try using another client like uTorrent. Some clients don't share well. I do know under certain circumstances I can't use my client and MSN and mIRC all at once. SOmetimes it's a software conflict. But try the small and simply uTorrent client and see what happens.

I have a similar problem. Sometimes when I test my port using uTorrent's speed guide, it says the port is closed and sometimes it says it's open. I have a static IP.

I got BT to do a linecheck. They said it was fine and bizarely everything has been working great. This suggests my settings are fine. I think when they do a line check it somehow clears the line

The plot thickens.
My Dad just logged on to the network and now things have slowed down quite a bit but I'm sure this isn't a bandwidth issue. Now as the connection problems i had before the line check were present whether I was the only computer logged on to the network or not.
What I really need to know is that can forwarding the ports that I have effect the way the network runs when others are logged on? For exampe I have forwarded the MSN Messenger ports. Will this cause problems when my Dad uses MSN Messenger on his computer where there is no port forwarding set up?

Sorry I didn't post all these in one message but I get carried away.
Anyway I tried downloading uTorrent to see if it was a software issue as mentioned in the first reply. I set it up forwarded with the same port (60000) and it slowed down my web browsing when uTorrent was running even though it wasn't downloading. I closed it, web worked fine, openend it web stopped, closed it web worked fine...
The crazy thing is I have had bitTorrent, MSN Messenger and web browsing all working wonderfully in parallel. What can i do?!?!?!?!?!?!?

Sorry again for not thinking of this in my last post. I wont post again until there are some replies.
I recently installed MSN Live. During that process it SPECIFICALLY suggested that I close bitTorrent so that the installation process would work. This suggests a conflict in the software. Any solutions?

Wireless can be tricky.
First, I dunno what MSN live is, but I'd get rid of it. I don't trust much w/ the letters MSN in front, lol.
It doesn't so much suggest a "conflict" as it suggests a "microsoft doesn't like this" or...well, I dunno.
Just because you have a wireless connection, and you didn't tell us what type I might add, 802.11a/b/g?
Even though you might be able to download w/ high speeds, you're capping out the throughput of the wireless connection, NOT the internet connection, if that makes sense.
I would shut down router/modem for about 5 minutes. Restart modem, wait till it powers up. Restart router, wait till the lights stop blinking, and reboot the computer.
Lastly, if your wireless connection is not secured, there is a GREAT liklihood that someone is leeching your connection and raping all your bandwidth. I'd also point out that just because your connection is secure, if you don't change the default router password, you might as well leave it insecure.
You can generally check this by logging into the router and finding the DHCP clients table...and looking for systems you don't recognize, and then booting them.

Hi thanks for your reply.
Well MSN Live is just the latest Messenger. I quite like it but i guess i could use the web based version.
The connection is 802.11g
The reason I don't think it is a bandwidth problem is that I have downloaded at much higher speeds without the connection breaking when things were working (100KB+) I have set the upload limit to 22KB.
AS i said with uTorrent just opened the web stopped working properly even when no downlaoding was taking place. At the moment I have no torrent client open and evrything is fine even if downloading with Ares (Rapper's delight - what a song!). Incidentally i don't have ares running if i'm running torrent.
The connection is secured. Admittedly the encryption has not been changed in a while but where I live I can assure you it is highly unlikely that anyone has been stealing bandwidth.
I have never seen an unwelcome ISP on the DHCP list.
It looks like the conclusion MSN has troubles with torrent but the big problem for me is that i have had both running in perfect parallel at times.
I have asked before but what i really want to know is can the port forwarding i have done for my static IP upset other users of the network, say if they were using MSN at the same time?
Hope someone can help, cheers.

YES, port forwarding a program that doesn't hop ports will interrupt use for other users.
YOU have 62000 ports or whatever, so does every computer. So does the router.
So...since the router controls everything, if the router's already forwarding a specific IP (MSN, for example), it won't allow someone else to forward too.
I'm honestly surprized you HAVE to forward for messenger. Generally routers allow AIM/Messenger type programs through w/ no problem.
I don't honestly know beyond that. I know that sometimes they just do weird, buggy things, wireless and others. One of the wireless networks I run will flop all around speed-wise, even though it's very near the router. Sometimes loading AIM will timeout FireFox...sometimes I'm sucking stuff down at 400k. Could just be network latency issues, I'm not sure.

Okay well I actually forwarded the ports for MSN as I thought it might help my problem. With the usual intermettent style of computing problems I had thought that this would solve my problem as things woked for a while but that was probably just a coincedence. I'll reverse them as it were...
I also forwaded the port for iTunes. This was probably unecessary right? It would only be a problem if others were downloading podcasts at the same time so it's not really a problem.
Thanks again

Hi, Just one further question:
If I have forwarded a port for bitTorrent would it make a difference whether I have uPnp enabled? Could this have any effect on my problems that occur when running MSN Messenger and bitTorrent?

UPnP is a tricky animal.
It's supposed to be smart enough to be able to be run from several applications at once w/o interfering...all it does is automap ports on the router.
I used it for a long time until it crashed and burned and wouldn't work anymore for me.
I don't really undertand your problem...
IF you use UPnP w/i the torrent program, you have no need to forward the port @ the router. It shouldn't cause a conflict because the router doesn't know the name of the software you're forwarding to, but...it might, because UPnP is buggy.
If you're asking if you can use UPnP w/ several computers all using different ports on the same network, that should be fine as well, assuming that UPnP works correctly.

I was just wandering if once i have port forwarded whether the uPnP option made a difference - ie would it ignore the port i have forwarded it too.
Something else to consider: I have tried uTorrent and now Azureus and both really screwed up the connection (nothing really worked) whether downloading or not. I am reasonable competent and I believe I had them set up to the correct standards ie port forwarded and not too many ports open for connection to conflict with other programs.
Seeing as these 2 both cause the same problem and bitTorrent causes similar but less problems I wonder if that gives you any more clues?

okay we maybe nearing an end to this thread!
I tried Azereus again but this time through the sam port that i was using for bitTorrent. Before I forwarded another port (51234) in exactly the same way except that the forwarding test cam back negative.
At the moment FireFox, MSN Live and Azureus seem to be working in harmony. This has happend with bitTorrent before but I must live in hope that this is the end of it all - yeah right!
thanks again for all your help. Don't be suprised if this thread continues...

No this is crazy. This morning, as before, the internet stops when Azureus is running. When I say running I mean the program is open. There are NO TORRENTS downloading or uploading. In this situation I can contact my router no problem. Can I ask my ISP provider (BT) to do something or will they reprimand me for using p2p software?

I've read stuff about service pack2 limiting the number of connections at anyone time. I had Azureus set up to a maximum of 10 and still had problems.
think i should remove SP2?

I had similar problems on my network using Belkin wireless adapters.
I switched everything to linksys and dlink and now everything works great.
Try unplugging your adapter, waiting about 15 seconds, and plugging it back in when it fails. Check in the device settings to see that windows doesn't power it down.

Well I'm gonna give up and just accept that I can't chat on MSN when i'm downloading anything! Sometimes it works but most of the time it doesn't. I have the same problem with Ares P2P as welll.
Thanks for all your help anyway...
