I need help on figuring out what to debug for this issue.

2.4 Mhz Wifi to Router to wired machine: 69 Mbps
2.4 Mhz Wifi to Router to xfinityspeedtest: 72 Mbps
2.4 Mhz Wifi to Router to any internet speed test: 20 Mbps

5 Mhz Wifi to Router to xfinityspeedtest: 130 Mbps
5 Mhz Wifi to Router to any internet speed test: 130 Mbps

These speeds are very consistent. What would be the cause of the 52 Mps difference between xfinityspeedtest and inter test sites? My hunch is that this is at the packet level.

Not one clue what router we are talking about or what build release number.

The this behavior is occurring on both Broadcom and Intel wifi adapters. I removed, added, changed the DCSM resetting in the script section to no avail. Wire Shark is showing some DCSM class 1 packets. The only thing not really stock on DD-WRT is tweaking the Fragmentation & RTS down 12%.

Also, you should consider upgrading to a more recent release of this firmware.

Based on tatsuya46 sig

[BROADCOM] DIR-860L A1 -------------------> DD-WRT v3.0-r43281 std

I installed r43290, since every build tatsuya46 references in his sig for the DIR-860L A1 exists in a place I can never locate. Thanks for the newer build suggestion kernel-panic69 and links to old issue resurfacing in some fashion again.

Xfinity speed test is in the 42Mbps range
Internet Speed tests eventually get to the 42Mbps range.

Each new speed site test initial posts really bad results. Rerunning the test one or two more time steadily increased the speed. In one of tests the actually plot was straight linear angled line of speed increase over time.

This is the fastest N internet connection I have obtained to the internet on this router / client setup. Still curious on how xfinity speed test was able to obtain a 86Mbs rate for a couple of days and if the reported speeds were real, and if so why the halving of the rate when leaving xfinity for the internet.
