Solved TL-WR841N Optimization? Need some expertise

[zapp22]

hi network gurus
I'm a novice at optimizing throughput. I really like the TP Link TL-WR841N router as do a lotta others.
I have three routers in a WIFI bridge arrangement, with the TPLink the mothership. I'm using their stock firmware, latest version. It works well - I'm getting from it every speck of my paid througput from TWC Roadrunner - same speed WIFI as via cable.
On the subtending routers repeating the primary AP its a mixed bag. One is running DD-WRT and the other a Ralink running their firmware.

I have seen comments here and there about optimizing WIFI throughput with things like:
- Turning off QoS [though some say the opposite]
- Using 20 only or 20/40MHz ? and
- 2.4Ghz only or 5?
- chunk TKIP. Use AES only? [WPA2/personal]
- avoid usb 3.0 connections. some are emphatic about this but its not much of an issue for me either way
- enable WMM ?

Also I do have a media server [simple: XP Pro on a good pc, hardwired to the primary TL-WR841N] and I do stream movies and music off it.

What say ye?

Your My System Specs don't make a lot of sense. Could you also do this tutorial so are experts have a good idea what they are working with.

Then we just wait for a network expert.

thx for that. MY inquiry isn't really "problem" solving so I'll get out of the way.
Just looking for tips on making a good network better. I think maybe that WIFI Analysis tool from CNET is a little dated??

I think I'll get what I'm seeking on smallnetbuilder forum.
