Re: PXE Network Boot

Sytra - you're a star !!

I've got the port speed fixed at 100Mbs, but duplex left as auto and it works!
(I did try to set duplex to full - but that broke it, so I took it off again !)

Thanks for your help.

Re: PXE Network Boot

That should tell you it is a problem with the switch configuration. I'd got that far.. but I figured there's more chance of a cisco person here than a PXE Booting Pi person there ! The Pi talks to the network fine (via the 3750) if booted from a card, this is something to do with the PXE element, j...

Re: PXE Network Boot

Hi All, Dragging up an old post - but I too have a cisco 3750 switch - which i'd like to use to connect a PXE boot Pi. The Pi boots fine from a generic unmanaged switch, but plug it into the 3750 and nothing. (non poe switch, with seperate poe injector in both cases) my switch port config: interface...

Re: New Raspberry Pi model 3B+ 1.4 GHz, 330Mbit Ethernet, 802.11ac, PoE

You sound like you have a fake "genuine" PSU there as the official supply is only sold in 2.5A varieties There used to be--as I recall--2A RPF PSUs, back when the Pi2B was the top of the line. Such as this one: http://www.cpmspectrepi.uk/raspberry_pi/MoinMoinExport/USBPowerSupplies.html#The_.22Offi...

Understood, might be worth warning people - lots are likely to get the Lightning Bolt issue and be checking their PSU when its nothing to do with it (well it might be, but ...)..

Re: Ethernet/USB bottleneck

5Ghz wifi is illegal in the UK That is must certainly incorrect, 5Ghz is a standard wifi frequency range - all new 802.11ac routers use it as standard. Throughput on these is (theoretically) up to 6.7gbit/s - although how you do the backhaul at that speed in a home environment i'm not sure !!! Greg

Re: Sd card no space! i tryed 6 hours!

Which partition are you expecting to see the space appear in? If you're expecting it in /boot (which is the only partition Windows can see natively) then you'll be looking for more than 6 hours! To confirm this, fire up the pi, navigate to a command prompt and execute df -h that'll show the free spa...
