I was going to write an article triggered by Steven discussing feeling a little left out (20070109.2030 entry), and even had it half done, but I’ve gotten sidetracked thanks to being utterly fed up with my connection issues. I’ve been having problems for around a month now, and they’re getting worse.
Here’s the short recap: I use a wireless-enabled Linksys router attached to a Speedstreem DSL modem. My main system (Rogue) is wired, but my 2nd system (Stratos4), the family system (Soupbone) and my laptop (Zod) all use the G-band wireless. For some reason, I’ve had increasing problems with my net connection seeming to drop out, and generally slow craptastic download speeds while using this router. When I switch back to an older all-wired model, these problems USUALLY disappear. At the least, they’re not as severe.
Bittorrent seems to be related to the problem, but exactly how, I don’t know. IIRC, the whole issue started when I noticed my downloads were often being rejected with a message that port 6881 was blacklisted by thus-and-so tracker. Firefox seems to default to that port, so I stopped using it for DL’s and shifted everything to Azureas (2.4.0, later 2.5.0), customizing it to a high port #. Shortly afterwards, the random connection losses started. “UPnP: Lost connection to service ‘WANIPConnection’ on UPnP. I get this message 3-5 times in quick succession, and all downloads and uploads stop. In the course of an overnight run, this will happen at least 100 times. (I came home from work one day and had 500 such messages waiting) Some of the messages are different:
“UPnP: Mapping ‘Distributed DB (UDP/port#)’ has been reserved by xxx.xxx.xxx.101′ – Please select” (truncated)
“UPnP: Maping UDP Tracker Client Port (UDP/port#) has been reserved by xxx.xxx.xxx.101′”
The port numbers are the ones I selected for Azureas and have the router forwarding to my system. However, I’m sure that *sometimes* the forwarding is wrong, because my system might be given a different IP by the DHCP service. It seems to make no difference though — I still get the messages, and the downloads work…after a fashion. Uploads are totally unaffected, as far as I can tell, until the network loses connection to the internet. Moreover, when I lose it, so does everyone else on my network, and the systems can’t even seem to talk to each other. The lights on the router go crazy. Net storm?
