![]() If I push the router much beyond that, the performance crashes into the basement and a reboot is required to recover. ![]() dial them down by A LOT.Īfter fiddling around for half the day, I finally found the right balance between performance and stability: ~120 max simultaneous connections. The Solution: To effectively use apps that require lots of connections (such as aMule and other P2P apps), you need to dial down the max simultaneous connection settings. The Cause: The B1 2.00NA version of the DIR-655 does not seem to be capable of the same 200+ max simultaneous connections that the old A4 version was routinely reported to achieve. While I have found what looks like the solution, it's bittersweet at best. Has anyone seen this behavior and, if so, did you resolve it? How? D/L speed after 30 minutes: 1.21 MB/sĪMule avg. D/L speed after 10 minutes: 443 kB/sĪMule avg. D/L speed after 60 minutes: 46 kB/sĪMule avg. D/L speed after 30 minutes: 255 kB/sĪMule avg. D/L speed after 10 minutes: 98 kB/sĪMule avg. So, to isolate the behavior to the router and eliminate the possibility that it's my modem flaking out or my ISP shaping the traffic, I wired my PC directly to my modem. My old WRT54G2 (R.I.P.) never had this problem with the same modem.Once more: The behavior is the same whether the PC is wired or wireless.As a last resort, I even tried the DMZ host option. I have toggled SPI, NAT endpoint filtering, QoS engine, DNS relay, traffic shaping in various permutations - all with the same end result.I am not running any firewall software after the router.aMule begins with Hi ID, but drops to Lo ID within 30 mins.I use a static IP on my Arch Linux computer where the P2P apps run.The router logs show nothing of note with all logging options enabled - no dropped packets, blocked connections, etc.Whenever P2P traffic is degraded, other traffic appears unaffected - web browsing, streaming media through my Roku device, VoIP, all continue to work seemingly fine.I've also tried the Virtual Server rules to no avail.(I have confirmed that the required ports are open and being used with a variety of utilities - Wireshark, online port checkers, etc.) Port forwarding for the apps is setup correctly this is the only reason they work reasonably well immediately after a reboot.I have reverted to factory defaults and started over multiple times.Basically, whether I am wireless or hardwired, apps like aMule and Transmission work _almost_ acceptably after a fresh router reboot but then speed begins to degrade within about an hour, finally slowing to a crawl and requiring another router reboot. I recently picked up a DIR-655 B1 2.00NA and have had speed issues with P2P apps ever since. Sorry so long trying to avoid a Q&A thread volley.
