- AES, WPA2-security (before TKIP)
- Enable AfterBurner? = Enabled
- Enable Frame Bursting? = Enabled
- Enable WMM? = Enabled
- Enable WMM No-Acknowledgement? = Enabled

Well don't know which one really helped but after a reboot I could connect with 802.11n.

Afterwards I installed jperf/iperf for troughput test:

Laptop --> WL500W --> Server:

and tried out several channel configuration. There are around 6 others AP in 2.4GHz band, 3 are using also n-draft. Therefore I played around a lil bit with the channels settings and channel width. The laptop was located like 3 metres from the Wlan-Router

Result:

The maximum I could achieve was a signal quality of 65 %!!! The transmission rate was never higher than 35 Mbit/s. There was no significant difference using channel bonding (40MHz) or just 20 Mhz channel width....well the connected rate was 270Mbit and not only 135 Mbit. I know that the other APs can influence the connection but should be the signal quality that low? Also the troughput is kind of annoying.

For crosstesting I used my old D-LINK DI504-G-Router. He immediately had a better signal quality and performed with 20 Mbit/s which is for a G-Router quite ok.

Anybody has any ideas?

Enable WMM No-Acknowledgement usually is a bad idea to turn on.
it can cause packet drops and confusion among the wireless clients

afterburner only works for G networks

and frame bursting should only be turned on when less than 3 client's.

apart from that... it's an early N router, the standard wasn't defined yet so some wifi cards work better than the others.
35Mbit is not too bad for this one tbh, sorry if I disappointed you with that

I'm not sure about dd-wrt as well... I used it once a long time ago, and I had lots of packet drops.
