Have used the try it idea

With what Alt-F version?

and still experiencing the same, wget ftp://ftp.sunet.se/ls-lR.gz from my laptop connected using wireless is getting 1.6MB/sec but the same command from the NAS connected using an ethernet cable is only getting 1.03MB/sec.

You might have a point here.
I executed the very same command from my desktop computer and got 5.21 MB/s, while from the nas I got 820KB/s!

I usually measure read/write transfer speeds between the nas and my desktop computer, just to sort other things out.

Two posts above I corrected the ftp read speed from the nas to 19.5MB/s. I measured now the ftp write speed to the nas, in the same conditions, and it is 12.7 MB/s. RAID1, ext3, IPv6 enabled.

I got those values invoking ftp in the desktop computer to read/write to the nas.
Using wget in the nas to receive by ftp the same file from the desktop computer, I only got 7.6MB/s.
So wget is not as fast as ftp. Does an ftp client make sense in a file server? hmmm... as a package?

Have tried changing the network cable and ports, have tried downloading to different disks, have tried using scp over the LAN and still experiencing these slow speeds. Other than changing the router I'm all out of ideas.

Well, start from the very basic, nas to computer direct cable connection, no router, switch, whatsoever. You might have to assign static IPs to the nas and the computer.

In the lack of an IP in flash (set when using System->Settings->Save Settings), or a DHCP server, Alt-F will try 192.168.1.254, 192.168.1.253, ... until it finds a free IP.

Some notes on IPv6 on Alt-F:

IPv6 is alpha on Alt-F!

If IPv6 is enabled, you can see in the status page, network section, something like
IPv6: fe80::280:5aff:fe53:1c38/64
Or in Setup->Host, you will see "Enable IPv6 (currently in use)".
For the moment, even if IPv6 is not explicitly enabled in the above page, some apps can deploy it automatically. NFS, avahi, forked-daapd, cur -6, and others, so the best is to check the status page regularly.

There might exists some issues with routers and IPv6, that is why some people disable IPv6 in their computers. But the issues are generally related with name resolution (DNS) and are more noticeable in browsers.

I used the try-it with version B6 again, I can't find any download links for B5 or any other versions :S

Have tried with a direct cable connection between laptop and NAS, and the speed maxes out at around 2MB/sec, which is the same as when I transfer locally with a router between the two devices. 

Is there any way to backup my current configuration and try out one of the vendors firmware's, such as 1.09? I've spent some time getting minidlna working perfectly with my samsung tv and compiling various other libraries/programs. Really don't want to lose all of that. I think everything such as /ALT-F and FFP have been installed to Volume1 so if i remove my drives, and then reflash the vendors firmware will I be able to run some tests, then reflash with ALT-F1 and then plug the drives back in and be in the same position I am now?

Cheers.

You have to select "Search All downloads" in the download page. But B6 (or B6+ in the experimental) should be fine.

This is really odd. Have you tried more than one network cable? Try it first.
Please report back when you sort-out what is happening.

Yes, but you have to use another disk to test the vendor's firmware.

Settings and files for disk-installable packages are stored on disk, if you remove the disk they will survive.
If your fileystems are ext4 then the vendor's firmware will not be able to read them, anyway.
If you have used Alt-F disk wizard, then the vendor's firmware will not recognize the disk partitioning scheme and will prompt you (if you are lucky and/or that issue is already sorted out) to format the disk.

System-related settings are stored in flash, and you should clear settings in the Firmware Updater when flashing the vendor's firmware back (is selected by default on Alt-F-IPv6).

If you have flashed Alt-F-IPv6, which is on its way to B7, then in System->Settings you have the possibility to upload the current system settings to your computer, and download and use them latter.

Re-flashed a few times and for some reason it *seems* that the speed issues have now gone, well I've been able to achieve ~10mb/sec over a LAN ftp transfer and a wget has maxed out my download speed so hopefully it's all sorted now.
