avatarl Posted December 11, 2005 Report Share Posted December 11, 2005 Not that. 1.2.2 was perfect or that I have an extraordinary router (not D-Link though), but at least it could keep up for a day or so without needed me to repair Windows wireless connection. But since 1.3, Windows connection is failing every couple of hours. Any general suggestions for configuration? Link to comment Share on other sites More sharing options...
Firon Posted December 11, 2005 Report Share Posted December 11, 2005 Get a better router/WLAN card? :/ Link to comment Share on other sites More sharing options...
1c3d0g Posted December 11, 2005 Report Share Posted December 11, 2005 Maybe you could try lowering Global Maximum Number of Connections...but if a Wireless Router keeps dropping its wireless connection after some hours, usually it's not a good sign (BitTorrent is probably overloading its networking capabilities). :/ Link to comment Share on other sites More sharing options...
ICleolion Posted December 11, 2005 Report Share Posted December 11, 2005 Have you downgraded to 1.2.2 to see if your connection problem disappears? Link to comment Share on other sites More sharing options...
rbgolfer Posted December 11, 2005 Report Share Posted December 11, 2005 I am having the same problem, but I am running a high end wireless router. (Pre-N) I had a few problems with 1.2.2 but since the upgrade, it is crash after crash. Link to comment Share on other sites More sharing options...
spriseris Posted December 11, 2005 Report Share Posted December 11, 2005 i would definitely try downgrading and see if the problem disappears. Link to comment Share on other sites More sharing options...
bibber Posted December 11, 2005 Report Share Posted December 11, 2005 I was experiencing similar (though not exactly the same) problems with 1.3. Just downgraded to 1.2.2 and my problems are gone. I will try to provide details.System details: Asus M6N laptop, Intel Pentium M 1.4GHz, 512MB RAM, Windows XP Home SP2Internal network: Intel 2915bga 54Mbps WPA connection with Linksys WRT54G wireless routerExternal network: 8Mbps/1Mbps ADSLNumber of torrents seeding: 8 (50KB/s capped)Number of torrents downloading: 4 (+/- 50KB/s)Now with 1.3 every single tracker connection ended in an 'timed out' message, marking all torrents with a red and white forbidden sign. With 1.2.2 only 4 torrents are flagged (2 seeding, 2 downloading). Also, what's interesting, the "Network OK" message at the bottom of the screen was never displayed in 1.3, neither a "NAT error" message, the area just stayed blank. Now on 1.2.2 the "Network OK" message is back.I tried to diagnose the problem in 1.3 by specifying a local HTTP proxy which maintains some logs. Interestingly enough most of the failing trackers did not even show up in the tracker logs. uTorrent showed a "Proxy error: timed out" on those trackers, implying to me the socket connection to the local proxy (127.0.0.1:8080) failed. Some of the connections did show up in the log, but were closed by uTorrent before any response came back.Lastly surfing the web with uTorrent 1.3 running was a drama. Many slow connections and timeouts. At first I thought it was my connection, but now that I have 1.2.2 installed I saw an immediate improvement.Edit: Now I'm back on 1.2.2 things are better, but still not perfect. My download speeds are much better, but I'm still seeing massive timeouts on the trackers.Here's a screendump (names of torrents hidden for privacy reasons, and no it's not porn ): Link to comment Share on other sites More sharing options...
Nanaki Posted December 12, 2005 Report Share Posted December 12, 2005 Yesterday and today my two torrents were unable to connect to their trackers and weren't downloading, but uploading. Also, my internet became unbearably slow when running.Now I started up 1.2.2 and they start downing immediately and my internet browsing is normal. I also have a wireless connection.

Reverie Posted December 12, 2005 Report Share Posted December 12, 2005 yeah... 1.3 does seem to put a strain on the wireless department... could it be because of the more aggressive behavior at getting peers/seeds putting too much of a strain for it to handle? I killed a DI-624S in 6days... got a DGL-4300 right now and it seems to be holding up against the pounding... of UTorrent and other stuff Link to comment Share on other sites More sharing options...
1c3d0g Posted December 12, 2005 Report Share Posted December 12, 2005 Hey, now I remember! - Fix: Upload a little bit more aggressivelyMaybe that is what's causing all these wireless connections to drop... :| Ludde, what did you do? Link to comment Share on other sites More sharing options...
junkaroo Posted December 12, 2005 Report Share Posted December 12, 2005 I am getting the similar issues since my 1.3 upgrade from 1.1.7.2.utorrent causes the wireless connection to cease functioning (though the network connection icon in the system tray appears normally connected). It requires a repair to fix. No other computers in the house (wireless or hardwired) are disconnected as a result of this.I will downgrade.

Firon Posted December 13, 2005 Report Share Posted December 13, 2005 1.3 attempts to make more connections/second (if your net.max_halfopen is higher).1.2.2 and lower use 0-16, 1.3 0-30.It's not a µT problem, it's that your hardware is a piece of crap and can't handle so many connections. I'm sorry to say it, but this is the reality of the situation.Lower the value in bt.connect_speed to 16 (the old default)To re-iterate: IT'S NOT A µTORRENT PROBLEM, IT'S YOUR HARDWARE THAT'S NOT VERY GOOD AND CAN'T HANDLE LOTS OF CONNECTIONS, LOWER THE PREVIOUSLY MENTIONED VALUE TO COMPENSATE FOR YOUR HARDWARE Link to comment Share on other sites More sharing options...

When my family is in the house, about three different torrent clients are open, causing of course, a lot of connections, which so far hasn't been a problem. When I use Azureus (with more open connections set than my uTorrent) it also connects like normal. uTorrent 1.2 also connects like normal when I make more connections. Lastly, I tried lowering the previous mentioned value and it didn't have any effect.Also, today, uTorrent 1.3 wouldn't work with the wireless network of my university. And that's one hell of a network.Nevertheless, I don't mind, as I just stick with 1.2 or Azureus. Link to comment Share on other sites More sharing options...
JWolf Posted December 13, 2005 Report Share Posted December 13, 2005 I have a Linksys WRT54G router and it does not work well with DHT. With DHT enabled, eventually the router will slowly start to crap out requiring a power cycle to reset it It gets to the point where trying to access the router's web interface can fail. So if you have DHT on (two check boxes that needs unchecking), turn it off and see if it works with your router after that. Link to comment Share on other sites More sharing options...
spriseris Posted December 13, 2005 Report Share Posted December 13, 2005 two ideas:if you have a Linksys WRT54G, make sure you're running official firmware v4.20.7.. or using one of the 3rd party firmwares such as Tofu's HyperWRT, or DD-WRT.UPGRADE YOUR NETWORK CARD DRIVERS. or change network cards altogether. My 3COM LOM (3C905) (lom = lan on motherboard.. integrated network card) is *crap*. I recently discovered this, and updated my Linksys LNE100TX drivers to v5, and started using it instead. This helped me a lot. I realize that I'm using a wired interface card, but the same advice goes for you wireless users. PS. I have a wonderful new laptop.. and the built-in wireless (Atheros) is CRAP! Link to comment Share on other sites More sharing options...
geezer Posted December 13, 2005 Report Share Posted December 13, 2005 How busy does the client have to be to start having problems? I've had no problems with version 1.3 but maybe I don't generate enough connection activity. I have a Toshiba notebook with built-in Intel 2200BG wireless and a Motorola SBG900 all-in-one cable modem, router, and wireless AP.Every now and then I lose my wireless connection for a while (wireless connection icon pops up in the system tray) but that's due to my stone-age neighbors using their 2.4 GHz cordless phones (grrrr). That will happen whether I'm running µTorrent or not. Link to comment Share on other sites More sharing options...
bibber Posted December 13, 2005 Report Share Posted December 13, 2005 As posted earlier I too have a Linksys WRT54G (firmware v4.20.7). In response to the postings here I did some more testing. My general procedure for these tests:1) Start uTorrent with 12 torrents loaded, 9 seeding, 3 downloading.2) Wait two or three minutes.3) Right click all working trackers in turn and do an 'Update Tracker' to see if they keep working.Between the tests I gave my router two to three minutes to calm down.Now these are my results:A) 1.2.2 disabled DHT: 4 trackers failed at first, 4 after doing manual updates. 1.2.2 enabled DHT: 4 ..., 4 ...C) 1.3 disabled DHT, bt_connect_speed 30: 4 ..., 12 ...D) 1.3 enabled DHT, bt_connect_speed 30: 4 ..., 12 ...E) 1.3 disabled DHT, bt_connect_speed 16: 4 ..., 11 ...F) 1.3 enabled DHT, bt_connect_speed 16: 4 ..., 9 ...Not satisfied still I disabled my wireless connection and got some UTP to connect my laptop directly to the router:G) 1.3 disabled DHT, bt_connect_speed 16, wired network: 4 ..., 12 ...H) 1.3 enabled DHT, bt_connect_speed 16, wired network: 4 ..., 10 ...Those 4 trackers were the same everytime and I verified them to have connection problems indeed.I still think something's amiss in 1.3. Debugging a single tracker I get this:1) Let uTorrent startup: tracker connection OK.2) Do a 'Update Tracker' within uTorrent: tracker connection timed out.3) Open a Cygwin command prompt and do a 'curl -I' to the tracker url: tracker connection OK.4) Go back to uTorrent and do another 'Update Tracker': tracker connection timed out.Now what sense can we make out of this? Is there anything else I can change in the 1.3 environment?I'd like to debug this problem, but in the meanwhile I'm back on 1.2.2. Link to comment Share on other sites More sharing options...
Firon Posted December 13, 2005 Report Share Posted December 13, 2005 EVERYONE HERE USING A WRT 54G/GL/GS SHOULD READ THIS, IT'S A SEVERE PROBLEM WITH THE ROUTER'S FIRMWARELinksys routers do not handle P2P apps very well, or even a lot of connections. They have a lot of bad settings in regards to TCP timeouts with default firmwares. Namely, they track connections for 5 days, obviously overloading the router very quickly, sometimes even causing it to completely freeze. Even firmware replacements don't fix it, but with alternative firmwares you CAN fix the issue.Change your firmware (if you switch to HyperWRT2.1b1 tofu11 (54G/GL only)] you don't need to do this step, it's pre-set in the firmware) and put in a startup script:echo 4096 > /proc/sys/net/ipv4/ip_conntrack_maxecho 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcastsecho 1 > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responsesecho "600 1800 120 60 120 120 10 60 30 120" > /proc/sys/net/ipv4/ip_conntrack_tcp_timeoutsHyperWRT2.1b1 Thibor (54GS only) (requires this step) Go to the web interface, click Administration, Edit Startup, put the command in there and hit Save, then Save settings.HyperWRT2.1b1 tofu11 (54G/GL only) (doesn't require this step)You're on your own for other firmwares.Also Nanaki: a lot of NICs (especially wireless ones) seem to have problems with the number of connections µT makes. Integrated stuff is often worse. Try updating your drivers (and lower net.max_halfopen if you raised the value before). Make sure you restarted µT after changing those options. If turning off DHT helps, then it means that the number of connections mainline's DHT generates is too much for your NIC.junkaroo: turn off DHT, sounds like something (NIC, modem, router) doesn't like the UDP packets. 1.1.7.2 didn't have DHT (which uses UDP packets) which may explain your problem.

Primus Posted December 14, 2005 Report Share Posted December 14, 2005 Would like to add to this, since I'm a DD-WRT user.The current beta 23 release of the DD-WRT code (12/12/05) contains a fix for this problem. So if you upgrade to it there's no need for the startup script anymore. Link to comment Share on other sites More sharing options...
Firon Posted December 14, 2005 Report Share Posted December 14, 2005 Alright, I'll add that to the FAQ as well. So that's two builds now that fix it, DD-WRT b23 and HyperWRT2.1b1 tofu11... Link to comment Share on other sites More sharing options...
bibber Posted December 14, 2005 Report Share Posted December 14, 2005 Will try the firmware update for the router later, but can anybody explain what changed in 1.3 that would suddenly break the router? As described before, why can I setup a TCP connection to a tracker outside of uTorrent (using the same router!) just fine and is uTorrent itself unable to create the connection?As said I will try the firmware, but I seriously doubt it will help.

Firon Posted December 14, 2005 Report Share Posted December 14, 2005 - Feature: Added setting to control how fast utorrent tries to connect to new peers.- Change: Increase the amount of connects a bit.- Fix: Upload a little bit more aggressivelyI guess one of those did something to cause problems. By the way, did you patch TCPIP.sys? Or raise net.max_halfopen (especially without patching it)? Check the event log (eventvwr.msc) and see if there's any event 4226...You should still change the firmware though. Link to comment Share on other sites More sharing options...
