I have Linksys WRT54GL with Tomato firmware installed. When I connect internet cable directly to a computer I can download at about 8 MB/s, however when internet is access through the router maximum speed is up to 4 MB/s.

Statistics always show that there are about 3 MB of memory available, and CPU load does not exceeds 0.6. What else can be a bottleneck for the bandwidth.

EDIT: QoS is disabled.

Is QoS interfering? The cable guy was going mad wondering why my connection was only 6meg. Turned out I still had QoS settings for my DSL. – Jason Taylor Aug 29 '11 at 17:54

If you're talking about 4MBytes/s, i'd say that this is near the max that a wrt54gl can handle.

Here is the result of a IxChariot test, with streams in both direction.


Note the avg speed of 36Mbps, which 4.5MB/s.
