RT-N66U w/ Shibby 1.32 cutting Internet speed in half

[wazooda]

Hey all,

Cox recently upped my Internet speed to 300mbps.

When I connect directly from a PC to the cable modem, I get the full 300 (and then some).

However, once I put my router right behind the modem, all my speed tests get knocked in half to 150mbps.

I tried removing everything else from the router and shutting off wifi and then ONLY connecting my PC to the router to eliminate all other variables and the problem remains.

This is an ASUS RT-N66U running the latest Shibby firmware.

Any ideas why this is happening?

Thanks in advance!

BTW - I should also point out that moving data on the Intranet is not a problem. I can move multi-gig movie files to my NAS and get around 700mbps sustained.

Whelp... solved me own problem.

As a last-ditch effort, I flashed the Merlin firmware to the router and problem solved!

So clearly it is a Shibby issue.

The issue is not Shibby per se but more that you disabled the cut through forwarding. Shibby does not support it at all. If you enable QOS or any transforms in Merlin firmware the performance will be exactly the same.
