Bad routers
From VuzeWiki
List of routers that have problems with Vuze and how to solve them when it's possible
Contents |
[edit] Typical reasons
Typical reasons, why a router fails with Vuze traffic, are related to the fact that bittorrent traffic (and other P2P solutions) burden your network infrastructure quite much. There are both lots of connections to other users and high amounts of transferred data.
That may lead to router crashing due to e.g.
- too many connections : some home routers have buggy firmware and crash when there are lots of connections at the same time
- UPnP problems : some home routers do not handle UPnP very well and may crash or act weirdly
- overheating : some home routers do not have appropriate cooling, and may be subject to crashes due to heat, if you have constant data transfer
[edit] Due to (too) many connections
The following routers have known problems with too many simultaneous connections. Limiting "Max connections globally" in Vuze's Transfer options to 200 or fewer should fix the problems:
- D-Link DI-624
- D-Link DSL-G664T
- Linksys BEFSR41V4/BESR41
- Linksys WRT54G
- Linksys Wireless-b
- Netgear DG632
- Netgear DG834G
- Netgear MR814
- Netgear Rangemax 802.11n WPN824
- Netgear WGT524
- Netgear WGR614
- SpeedStream 5660 in Router/NAPT configuration. Latest firmware is 2.(3).7. Alternate workarounds:
- Switch to bridged mode. (For security, firewall your network.)
- When it dies, just power-cycle the router and continue on.
- W-Linx MB401-S (and SMC Barricade 7004 BR, which is identical in construction)
- WRT54G/GL/GS
[edit] Due to UPnP
- Zyxel Prestige 660hw
- D-Link DI-604
[edit] Due to Port Forwarding
- D-Link DI-514 (not port forwarding UDP protocol consistently)
[edit] Due to overheating
Most home routers do not have proper cooling. Usually no fan and not even heatsinks for CPU. If your router fails/locks after longer use, consider heat issues as a possible reason.
- Note: overheating issues may also apply to ADSL/cable modems and/or WLAN base stations
The following routers have known problems:
- D-Link DI-624
- D-Link DI-524
- D-Link DI-615
- Trendnet TEW-652BRP
Installing a small memory-chip heatsink to the router's processor may help to keep temperatures down. Example: 
[edit] Due to modem/router intrusion detection functionality
- Speedtouch 780 WL (KPN in Netherlands has enabled "fragment_out-of-order" firewall/intrusion detection function in modem. See forum discussion: http://forum.vuze.com/thread.jspa?messageID=200211#200211 )
[edit] Reason not yet verified
- Apple airport extreme (802.11g wireless with wep 128bit)
- Setting the router IPv6 support (under advanced) from local to tunnel may help in addition to the solutions listed below.
- Cisco 1841 Modular Router
- Starting Vuze and starting a torrent causes external internet access to fail. The following solution will only re-enable external network access until Vuze is started again.
- Telnet into the Router
- Issue the following command: Clear IP Nat Trans *
- Upgrading memory >128MB and installing c1841-advipservicesk9-mz.150-1.M.bin (release 15 IOS) seems to have magically cured this router
[edit] Usual solutions
- Updating the router firmware
- Note: If you consider yourself as an experienced user you can also try to install a 3rd party firmware if there is one for your specific model. Often those 3rd party firmwares are tuned for higher loads. But be warned: A failed firmware installation can render your router useless or require a complicated reset/manual firmware repair procedure.
- Restricting the number of connections globally in Vuze's Transfer options to something like 100 (or even below)
- Turning off the UPnP plugin and doing manual port forwarding
- Check that your router/modem has no firewall/intrusion detection functionality active, which might prevent connections
- Binding outgoing connections to a single port (see advanced network settings)
- Restricting the number of max simultaneous outbound connection attempts in the advanced network settings.
- Disabling the DDB plugin
- Connect to the internet without the router/only the modem (for testing purposes)
- Getting a new router if all else fails
