Router hardwired to Sipura 2102 (VOIP ATU) on 1st port with fixed IP. Home server, one desktop, and yamaha amplifier all hardwired. Two 2008/2009 notebooks using WPA2 wireless, Wii, and PS3 using WPA2wireless. Router is behind a ScientificAtlanta cable modem. Service is RoadRunner.
Have had trouble for more than 2 weeks now. With the following settings, have had zero disconnects during the past 2-days. Tried the beta roms, went back to 1.20, 1.21_nosecurespot. Didn't work.
The only ROM that works is v1.21 2008/10/09. File name DIR655A4_FW121B08.bin
After installing, hard reset modem then unplugged it for 30 seconds.
Used the following tweaks --
InternetSettings:
set provider to [TimeWarner],
set DNS: [1st=ISP's main DNS, 2nd=cablem modem IP]
NetworkSettings:
disable DNS Relay
set Sipura ATU with Fixed Address, plugged into port 1
Firewall:
disable SPI, set both to endpoint independent
QOS:
disable autouplink, Set 256kbps
Everything's quick -- phone service quality is above normal, no frequent dropping connections.
Thanks to those who've taken the time to publish their solutions & settings. In my case, it took a combination of several -- the DNS Relay, QOS setting, and SPI all seem to be buggy.
My 2 cents...
Cheers
