I measured the USB 3.0 performance using a wired gigabit network - transferring large files (mkv, avi, etc.)from a computer to the router. Only got 15-20 MB/s using a Seagate 4TB USB 3.0 drive connected to the router. Another 4TB drive connected directly to a USB 3.0 port on the PC gets 80-100 MB/s.

15-20MB/s is what you can expect from a USB port on a router with a good cpu like in the r6250, your PC cpu is 3-4 times faster and has a high-speed bus for transfers from the USB controller.
USB 3.0 port in routers means that it can communicate with USB 3.0 devices but you will not get 3.0 speeds. _________________ Kernel panic: Aiee, killing interrupt handler!
I've tried all the builds kong has for the r6250, using his guide for setting up wireless and I can't get the same speed and range as on stock firmware.
On stock I get almost all of my 30/3 connection, on Kong's about half that.
On my rt-ac68u and r6300 I get full speed on Kong's. _________________ I am far from a guru, I'm barely a novice.
Are you suggesting to stay on netgear fw? I'm only having issues with 2.4 band. 5 band A and AC are fine. I have been offered by netgear to exchange it by the warranty, but I dont know if it will fix the issue.
This is what I get. I have comcast 30/5 Mbps speed. Using older intel 54 Mbps on A band on 5 band I get full 30/5 speed. Same if use my intel 7260AC card on newer laptop in AC(5 band) mode. When I switch that old card from A 5 band to G on 2.4 band I get 8/5 speed, same when I use 7260 in 2.4 N. There seems to be the issues with 2.4 band side of my router.
I should have mentioned, the 5ghz band is fine regardless of build or fw. The 2.4ghz crawls sometimes to 5.5mbps on Kong's.
I haven't tried brainslayer's builds yet. I might tomorrow. _________________ I am far from a guru, I'm barely a novice.
I have suspicion that it's a hardware issue in R6250. So you have the same issue with 2.4 band, right? I didn't mention that I have a E2500 running tomato in bridge mode to R6250 on 5 band and as AP on 2.4 band. If I connect to E2500 on 2.4 band and bridge over to R6250 speedtest shows about 20/5 on any wifi card. The reason it is lower because there are a lot of APs in my area and it's overcrowded.
Let me know how brainslayer's build worked out.

Wouldn't make a difference. BS build is the same as my NEWD. Only thing that could be responsible for it is, that the init params are not correct. Maybde they fixed them and the dump I got had params that were not correct at that time. We could check it if you flash netgear firmware, do a reset and dump nvram.
ON the R7000 they changed the inits 2 times with firmware updates, they had typos all over the place in their default radio init params. _________________ KONG PB's: http://www.desipro.de/ddwrt/

I would love to create a dump of my stock fw. Could you point me on how to make it?
Thanks
ps. 2 gurus is better than one.
