Very strange that I'm the only one with this issue. I have six different RT305x based routers, same issue with all of them. DD-WRT doesn’t seem to utilize Ralink’s packet processing engine, because RT305x CPUs can easiley do wire-speed on 100 Mbit/s ethernet.


~100mbit with out PPE use may be only on RT3052. RT3050 ~40-50Mbit.

I`m use software fastpath in wive-ng-rtnl. Speed at RT3050 without use ppe ~80Mbit/s. CPU load 100%.

At 3052 + fastpath 100Mbit anf cpu load ~70%.

Source code for PPE (HW_NAT use) may be view in wive-ng-rtnl git.

Wive-RTNL settings default to

Use HTTP or SSH (or maybe Telnet).

Great!

Me need help to rewrite hw_nat code for support internal switch config.

Sfstudio, in recent releases of wive-ng rtnl, the "ethernet converter" option with operation mode=bridge is not there anymore. Can you tell how to create a wireless repeater or client bridge (lan+wlan in the same network, wan disabled)? Thank you!

I'm running 1.4.1 released on 03/08/2011 and it has bridge mode available.

Yes there is bridge mode available. In the previous builds before 1.3.7, there was an option "ethernet converter" connected to the bridge mode. I am asking about the missing "Ethernet converter" option in the "Bridge" mode.

This mode not support and not planned support in the future.

MAT/NAT2.5 extension is bad practic for 802.11. Use ETH Convert mode without NAT or use WDS.

WDS good for transparent infrastructure without layer2/3 frames modification on router.

Thank you for the reply. I will try with Ethernet Converter mode without NAT.

Ethernet converter without NAT is not working as client-bridge. I still had to configure wireless and LAN interfaces with different IP addresses even after disabling NAT in WAN settings. After disabling NAT in WAN configuration, both interfaces are supposed to be in the same subnet but routing table was not configured accordingly. Thanks again for the suggestion.

I went back to DD-WRT, which has at least a way to make repeater bridge work like client bridge although the repeater-bridge configuration is broken in the GUI after build 15778.

Re read my post. Client bridge with NAT2.5/MAT NOT SUPPORT and not planned.

Only route mode (with or without nat) or WDS support. It`s true, it`s good. RTFM.

I just spent several hours again trying to connect the WHR-G300N with Wive-NG-RTNL-1.5.1 to E1000 with TomatoUSB_build-54. Tested all router modes of WHR-G300N with NAT, without NAT, with WDS, without WDS. Did not work. I decided to try the original firmware based on Ralink SDK 3.3.0.0 for setting up the client bridge. It took five minutes to setup the client bridge and the WiFi performance is better than anything I have seen on this WHR-G300N (300 Mbps solid connection and ~95Mbps throughput up and down, practically limited by the 100 Mbps Ethernet switch). This is "true and good" to me.

WLAN to WAN = 25 Mbps


In mode ? I`m use 802.11N only mode WLAN to WAN 99Mbit/s on RT3052 and 70-78mbit on RT3050.

1) Try change powerl level
2) Try changhe channel and subchannel
3) Try select regdomain
4) etc...

Edit /etc/scripts/wifi.sh. String iwpriv ra0 set HiPower=0 replace to iwpriv ra0 set HiPower=1. Set 802.11N only mode/etc...

P.S. JAPAN 80211N support only(?) 1-11Channel. And subchannel only below(?) centrlal channel.

On distance to pair kilometers with 16dbi antennas you simply overload receiver input cascades. I would reduce power...

I lost many features and a nice web interface by going from DD-WRT to Ralink SoC SDK. Sad The only gain is throughput; this is what matters to me since I needed just a simple client bridge. Smile This is the simplest and best performing client-bridge implementation I could find. DD-WRT gives this functionality indirectly and by wasting some bandwidth through repeater bridge function (includes AP function and broadcasts the SSID). Wive-ng-rtnl did not work at all and I doubt its performance could have been faster (using WDS) than the Ralink SDK which already saturates the Ethernet switch.
