I have WNDR3700v4 and i get pretty bad wifi. I do not use 5 GHZ i only use 2.4 GHZ and my laptop is 1,5 meters away. I have 100 Mbit/s connection and i still get ~30-40 Mbit/s on my laptop. Today once i got 75 Mbit/s now it's still down to 30 Mbit. What is going on? In Openwrt it says 176 Mbit/s http://www.picz.ge/img/s1/1801/2/4/47fd95b53682.jpg
If channel selection is on auto, manually select channel 1, 6, or 11.
Use WPA2-PSK and AES for wireless security.
Use a wireless analyzer to see what your signal strength and quality is at the router, and what wireless traffic is like in your area.
I already have all those done! There are only 2 wifis one is my second has very weak signal.
Using ch 11 + WPA2-PSK + AES
In Advanced settings, start with 1350 for distance optimization, and 2346 for Fragmentation and RTS/CTS Threshold.
Changed distance to 1350 other settings already were 2346 and 2347
Also changed channel to 13 and i got 55/60 up down 
But still nowhere near max 94 up/down when on wired.
Wow i disabled sqm and now i got these speeds over wifi
Something misconfigured in SQM...
See the LEDE User Guide section on SQM and SQM tuning...

Corrected settings but still i get 59 up/down
without sqm i get 68/78 down/up
I do not believe WNDR3700v4 has so slow wifi. My 1 antenn tp link 740n had 92 Mbit/s on wifi LOL
Personally, I have Ingress and Egress set at the ISP rates, and get the same speeds on 2.4 and 5 as wired.
Start at 100% and work back in 5% increments.
You may get 68/78 without SQM, but how well is bufferbloat controlled?
On first link very bad on second much better results. I do not know which one to trust.
Because of no good measurement program i do not believe i need sqm. I can't confirm that it does what it's meant to. I just lose my bandwith that's all i can see.
I've had good results using cake/piece_of_cake, with no advance configurations.
If you want to continue, SSH into your router and run the following commands...

Should be the WAN eth0.2

I am using 0.2
Now i disabled sqm. I am trying to set up fireqos, but with fireqos wifi is even worse at 28-30 Mbit/s. These sqm qos things are killing my wifi.
With SQM enabled, SSH in to your router and run the following command and post the results...

100 Mbit/s for a month. Then 50 Mbit/s
But i get 94 Mbit/s now on wire
That's with SQM?
