ASUS RT-N66U running Tomato v 1.28 by shibby their modem > router > gb switch > desktop all CAT5e cables Old service was ~120/10. Upgraded tonight (same routing as above) and first test from speedtest.spectrum.com was ~140/20. This matches my new service of ~400/20, but only the upload, obviously. Ran a CAT5e from modem directly to desktop and saw ~450/20. Rebooted everything and connected again with my router in place. Same slow result for download as above. Found some things here and elsewhere, so I opened an SSH session with Putty and ran modprobe bcm_nat I saw BCM fast NAT: INIT in the output. No change in speed. The adapter is set to auto negotiation for speed and duplex. Sure would love to see the faster download speed! Thanks in advance.
