jmelgin Posted November 28, 2005 Report Posted November 28, 2005 Need some help. Every time I run uTorrent, my cable modem will drop the internet connection. Sometimes, this occurs after a few minutes of activity; other times it will happen after a couple of hours. When uTorrent is running, I'm getting 50-100 kbs down and have capped the upload to 10 kbs. If I exit uTorrent, reboot my PC, and reset the cable modem, my connection is good forever.Not sure what's going on here. I've set the max connections to 100 and also have port forwarding enabled. FYI, the modem is a Motorola SB4220 and the ISP is Comcast. No complaints about the modem or Comcast. This appears to be somehow related to uTorrent.Is it possible that the modem is being overwhelmed with traffic and is missing some basic comms with the ISP at a maintenance level? I know I'm reaching on that theory but am out of ideas.Any other settings with uTorrent to adjust? Anyone else have similar problems? Open to suggestions!!
Firon Posted November 28, 2005 Report Posted November 28, 2005 There's been a lot of threads about this before. Either your ISP is screwing with you (Comcast SUCKS), or your modem is a piece of crap Reduce the number of connections per torrent and globally and see what happens.
SledgeDG Posted November 28, 2005 Report Posted November 28, 2005 Surfboard modems are not that bad...I'm here on a SB3100 and never had any problems whatsoever...perhaps it is not working properlycall Comcast and complain...they can read out error tables onlineThere shouldn't be any "basic commands on maintenance level" except for the poll to check if you're still online or if they could assign your IP to s/o elseMore likely your modem is annoyed with the fact that you cap your up at 10 while beeing on cable (j/k)otherwise it seems like your ISP is messing with youDo as Firon suggested and see if anything changes
Fevves Posted November 28, 2005 Report Posted November 28, 2005 Have you applied "Event ID 4226 Patcher"? If you are running Win XP SP2 without it, maybe it has to do something with half-opened connections.
Firon Posted November 28, 2005 Report Posted November 28, 2005 It doesn't have anything to do with it at all.
valium Posted November 28, 2005 Report Posted November 28, 2005 I know exactly what your problem is, I too once has a Motorola SB4220, this cable modem has a severe design flaw, that is why most ISP's like using this modem. Once you acheive your max uload rate on this modem it freezes, now see'ing as you cannot flash the bios on the modem itself cause the bios is only distributed to people who sells/lease the modems to ISP's you cannot fix this problem. Here is what you can do to fix this problem, Call your ISP as many times as possible and annoy the hell out of them till they are forced to give you a new modem and not the same model I did this and got the upgraded black modem from my ISP and it works like a charm. This crash on the modem will also work on IRC, AIM, generally anything where you upload.Sorry my P button doesnt work 100% of the time.
jmelgin Posted November 30, 2005 Author Report Posted November 30, 2005 Update - I ended up setting the "number of upload slots per torrent" to 1 and it has worked just fine. I have increased the max connections to 200 and max per torrent to 50 without any problems. Upload rate is uncapped and averages 28-30 kB/s; Download rates vary from mid-40's to around 100 kB/s.It does appear that the modem gets screwed up with lots of upload connections or traffic above a certain rate. I'm now shopping for my own modem (vs. getting a random one from Comcast). Any suggestions on this? Any big differences between Linksys, Moto, DLink, and the others?Thx to all for your help!
Zeikzeil Posted November 30, 2005 Report Posted November 30, 2005 I'm having the same problem (I'm on DSL though). It's not my router or my modem that can't handle the connections, as the same amount of connections work quite well in BitComet. I'd rather use uTorrent though. Anything else that could be wrong?I think I've had these problems since DHT support got included, I've completely disabled it now, maybe that works.
Firon Posted November 30, 2005 Report Posted November 30, 2005 Did you have DHT on in BitComet?UDP packets are notorious for breaking crappy modems and routers.
Zeikzeil Posted November 30, 2005 Report Posted November 30, 2005 I had DHT enabled in BitComet and it never failed on me. uTorrent kept running since I disabled DHT, so far so good. I'll keep it running all night (it's 9:20pm here) and update this tomorrow.My router is a Linksys BFSR41 (v2) never known that to cause trouble. Modem is an Alcatel SpeedTouch 510.EDIT: No problems so far, it has been running all night and all day. Seems like the DHT support created this mess in my case.
