What speed is the service supposed to provide ?
?
Additionally, how are you measuring that speed ?
Is the speed measured with a web browser download ? If you take time to
enter the save location, then the browser {mozilla-based at least} will
already have been downloading, but it doesn't start counting time until
you choose the save location. You then get an artificially high kB/sec
figure that reduces down as time passes to the correct download rate.
[eg 1GB file. take 1 minute to choose location/name. at the moment you
hit save, there is already 1 minutes download received, in 1 second
leading to the artificial number]. I don't know why that would be
different though with only a firewall change.
Have you tried gkrellm ?
Have you tried wget ? It list the transfer rate during and at completion.
Have you set MTU to 1492 or less {to account for ADSL overhead} ?
In administration|network check set MTU to 1492.
By default it will be 1500. stuffing 1500 bytes into a 1492 byte packet
doesn't go - so the router has to break the 1500 byte packet into a 1492
byte packet and another one containing the remaining bytes and all the
associated headers. This can impact router performance - especially if
you have many outgoing network connections eg gnutella/bittorrent.
Are you using a default fedora iptables setup {ie by firewall and
security dialog}, or manual or other adjustments ?
Could you provide output of ifconfig {shows MTU and whether ipv6 is
enabled} ?
