Super slow 1810-24G

[AlexGray]

I have a ProCurve 1810-24G (J9803A) that has suddenly become super slow, even if just handling two devices, or one PC talking to its web interface.

When I say 'super slow' I'm not talking about dropping to a few Mb/s - it is down to speeds of the order of 10-100 bits/s. The panel image of the switch on its web admin page takes at least 3 minutes to load from fresh, or the brower times out before it manages to load.

I have tried resetting to factory defaults and numerous reboots, with no effect. 

The system description is currently: HP 1810-24G, PL.1.5, eCos-3.0, 1_12_8-customized-h

 I thought I would try uploading fresh firmware, PL.2.08, but the operation always times out before uploading even 3% of the firmware image.

All diagnostic lights and reboot time are normal.

Any help solving this would be greatly appreciated.

Are the rest of the network ports still connected?
A broadcast storm might cause super slowness.   I'd unplug all , except the management PC port

No, it happens with just one port connected, even talking to the internal web pages it is impossibly slow.

When it is on the network other hosts and switches work just fine, and the traffic lights aren't showing any unusual behaviour.

It's difficult to troubleshoot the 1810 switches. Do you see anything out of the normal in the switch logs. If you go to Diagnostics -> Support File you can see the port counters if you scroll down a bit. Do you see any errors or collisions on your management port?
