Hi,
after the upgrade to the latest version of dd-wrt we are experiencing slow speed on wired interfaces.

Before the upgrade, we had about 90Mbits on both directions from 2 routerstation (NODE<->AP) connected via cat5e FTP, now we have these results:

Code:
root@CA_MAN:~# iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[  4] local 192.168.2.2 port 5001 connected with 192.168.2.4 port 52902
[ ID] Interval       Transfer     Bandwidth
[  4]  0.0-10.0 sec   112 MBytes  93.6 Mbits/sec
root@CA_MAN:~# iperf -c 192.168.2.4
------------------------------------------------------------
Client connecting to 192.168.2.4, TCP port 5001
TCP window size: 21.3 KByte (default)
------------------------------------------------------------
[  3] local 192.168.2.2 port 45236 connected with 192.168.2.4 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.1 sec  23.3 MBytes  19.2 Mbits/sec


Firmware:
CA_MAN (05/27/13) std 192.168.2.2
CA_AP (12/20/11) std 192.168.2.4

We have about 40 routerstations, same problem on all.

u are not even telling us the setup. also mixing that old builds with current ones is not recommend especially if you are using N-card setups. this migth be a tx-queue-lenght problem.

Tnx for reply Sash, just three months of delay Smile

In the meanwhile I switched to OpenWRT and, finally, ALL is working as expected. I would have done it before Smile

I have abandoned DD-WRT after buying more than 70 licenses...
