Wireless Connection Rates Lower Than Expected

I'm about as new as it gets to DD-WRT. I bought an R6300v2 because I was tired of .11g speeds and this one is supposed to provide better coverage as well. The stock firmware was ok for me but whenever I opened BitComet the router would feak out and reboot. I put King's 23430M firmware on it and now it doesn't reboot.

I spent a few hours tinkering with it last night and getting some settings changed and adding a guest network. I noticed that the rate for the 5Ghz int is only 144Mbps and the 2.4Ghz is 218.5Mbps. When I connect to the 2.4Ghz the rate drops to 144/130. Sometimes I'll see the 5Ghz rate go up but when I connect it immediately drops similar to the 2.4Ghz 144/130. With the stock firmware I could connect between 144/300Mbps. I'm viewing these speeds on the WLAN adapter on my laptop which is right next to the router and on the status page.

My wireless settings are as follows:

2.4Ghz

  • Security Mode: WPA2 Personal / AES
  • Network Mode: Mixed
  • Channel: 8 (40 Mhz / Upper)

5Ghz

  • Security Mode: WPA2 Personal / AES
  • Network Mode: Mixed
  • Channel: Auto (40 Mhz / Lower) (not many people have 5Ghz around me)
  • Explicit / Implicit Beamforming: Both Enabled

Everything for both radios is default on the advanced tabs including power (71mW). I fooled around with some of the channel settings in the Basic Settings tab which sometimes made the rate drop but I can't get connected above 144Mbps. I've seen stuff about ACK Intervals but I don't see that setting in the GUI. If it is a manual command then I will insert it into the config if someone tells me what the command is and what the settings should be.

So to recap, I have a laptops with an A/G/N WLAN card that used to be able to connect at 300Mbps with stock firmware. Now with DD-WRT the advertised (in status page) and actual connection rates seem to be capped at 144Mbps at best. Any help would be awesome.

Just some info on me. I'm an IT guy who primarily works with Windows/Citrix/VMware. I know basic networking and wireless. The stuff in the advanced tabs is foreign to me so I don't usually mess with that stuff unless told to. I love command line (strange for a Windows guy) so if I have to telnet into it I'm fearless.

Thanks for the help. If anyone needs screenshots just let me know.

5GHz wireless performance

5GHz wireless performance would be better in you use higher Channel Width(80 MHz) and higher channel.

Thanks Subhra, I changed it

Thanks Subhra, I changed it to 80Mhz and set it to channel 161. Status page reports 1300Mbps. I know that will drop once a client connects to it if the client doesn't support that rate.

I have the very same question posted in the Nighthawk r7000 forum as well. Kong said that there is a way to force a particular data rate but performance might suffer. I'll choose reliability over speed but I was just wondering if you knew how to force a data rate?

Thanks again.
