Linksys WRT54G doesn't play nice with BitTorrent

Well I originally posted this as a reply to a thread about Linksys vs Dlink router but decided that perhaps more enlightened AT members can help me out with this problem.

I bought a WRT54G to replace my Dlink 614+ so I could get wireless-g + use the hacked firmware available for the Linksys. Well, everything installed fine, flashed to wifibox firmware, and everything was humming along fine. an hour later, internnet connectivity is down. Scratching my head, figure maybe it was the firmware? But anyway, reboot of router, internet connectivity back up. An hour later, same story. I spent about a day trying to figure it out, went to sveasoft firmware, then went back to stock firmware, same thing. After a couple of days of testing I narrowed it down to bit torrent traffic. I use Azureus, and tried the slow connection method, tried limiting global connections, and that worked (but i have to limit to something ridiculous like 10-20 or it will still bring everything down). So basically now what I'm doing is putting the Dlink in front, and I have the Linksys connected to the Dlink to provide the wireless services. All the hackable features are pretty much useless since it is no longer my main router. The D-link has been working fine ever since, no more network issues.

At first I thought it was an SP2 problem with the TCP connection limiting issue that I've read about, but that didn't turn out to be the problem. The Dlink has no problems whatsoever in the same conditions. It seems like the router is getting flooded somehow. Perhaps I just have a bad router, I don't know. Kind of weird though that if it was a router problem it would only manifest itself when it's bit torrent, that seems more of a software bug to me anyway. I've connected to mirrors to download linux ISO images (I usually max out my speed, and the files are large enough that the transfers are sustained for hours at a time). and I don't have any problems with surfing the net (it will be slow, but everythign won't go down and the FTP session continues to go).

I've tried the latest sveasoft from linksysinfo. tried wifibox, and also went back to stock. I can't figure out for the life of me what needs to be changed to allow torrents to work properly through the router. Other than the 54g connectivity I would've also loved to have all the features that the custom firmware provides (ssh, qos through packet shaping, bandwidth management, and all the other nifty things that I don't know what it does but I'm sure it could be handy 🙂 )
 
Hmmm... I just got that same router last week and haven't seen that problem with BT yet. Seems to run fine from what I have seen. When I got it, I put that sveasoft firmware on there and seemed to have problems keeping a good connection, and going back to the latest linksys firmware cleared that right up. Other than that I don't have any other suggestions for ya, but hopefully you will figure it out. I assume you have your BT ports forwarded and everything?

did you reset to factory defaulst after firmware upgrade? then reset and disconnect power?

you set the port fowarding right?
 
yeah i have the ports forwarded, though the problem is not with BT itself, my whole network seems to lose connectivity to the internet until the router gets rebooted. It seems like something is causing the router to flood itself.

I really cant figure it out at all, if there was a general problem with it and BT im sure it wouldve went around the internet by now, seeing as how popular bit torrent has become.

I've tried factreset and stock firmware already too.
 
really odd. do u have a friend with that router? test swap? because mine certainly works with bt.. or maybe contact linksys for an rma.
 
Hey, I have the GS version of that routher and had the exact same problem as you're having. As soon as I started using Azureus, surfing web pages practically stopped, no matter how many open connections I minimized in Azureus, it still happend.

The cure, I downloaded ABC Torrent and it works flawlessly, doesn't suck up cpu power like Azureus did.
 
cctyler thanks for the tip i will try using an alternate BT client, i think azureus is on all the computers, i like it a lot (even donated money 🙂 ) anyway its just so weird cause it works fine on my dlink so i dont think its hogging CPU, maybe the way it handles BT traffic is not to the Linksys's liking.
 
hm, if surfing web pages stops its because yhou've flooded the upload. i use azureus and it works fine. as long as u limit the upload so that its not all ur bandwidth
 
Yeah I've capped my upload to 20K/s (my total upload is ~ 45K/S). It also doesn't explain why it works fine (no change in settings) from behind my D-Link router which is where it's at right now.
 
I am using bit tornado, and edonkey. And I am having the same problem. I have a wired linksys router. and after a while of downloading, my internet crashes. its very frustrating.

I will also try the alternate BT and see how that works.

If I remember correctly, I used to have the same problem when using kazaa. What I found out was that when I connect via the "Primary connection" it would cause my internet to crash. When I switch it to the "Secondary connection" it would not crash, but my downloads are very slow.
