I've searched and read other posts on this here and else where (via google) but cannot seem to resolve the situation.
To help save time I've compiled a list of various tests (including bypassing the RV042) and configuration options.
Tests (via DSL Reports) :
without RV042 (direct connection to T1) 1410 up / 1410 down
WITH RV042 1094 up / 763kb down
new Cisco RV042
Firmware Version: 126.96.36.199-tm
WAN 1: Covad T1 via Samsung iBG1000 T1 Router (NAT Disabled, RV042 has been assigned public IP Address)
WAN 2 (Failover): Atlantic BroadBand (via Surf Board Cable Modem)
MTU has been set to Auto, 1500, and 1492 (currently set to 1500) - speeds remain slow
SPI Enabled & Disabled - no change
Setting for Internet Port Speeds (also tried 1512 up for WAN 2 in case of GUI related error)
I think that about covers it, please let me know if there is any other info you need me to provide and thank you in advance for any help you can give.
