<DIV>Mike, try setting a fixed IP address since there are numerous options that

wonder if this has something to do with the "illegal Angelia MAC address" issue,
reported here previously, that causes problems with managed switches that will
reject such a MAC. Apparently, cheaper less sophisticated, unmanaged
switches will blissfully pass the illegal MAC and everything works fine
again.</SPAN></FONT></DIV>

problems<BR></FONT><BR></DIV>
<DIV></DIV>I have an Angelia board that I purchased from Anan about 18 months
ago which I use as an SDR in my home 2m DX station on a 28MHz transverter IF and
also use in the field with our contest group.<BR><BR>Currently I use the Angelia
primarily on RX with CuSDR as I like the UI design and display.<BR><BR>The
problem that I have with the Angelia is that it appears to be very 'touchy'
(unreliable) with its Ethernet connection, obtaining a DHCP lease and talking to
my PC.<BR><BR>In my setup I have:<BR><o:p></o:p><BR><SPAN
style="mso-spacerun: yes">�������� </SPAN>1. my workstation PC -
Dell T3610, 16Gb, 6-core Xeon, etc. with Gigabit Ethernet<o:p></o:p><BR><SPAN
style="mso-spacerun: yes">�������� </SPAN>2. my Linux server
which is my default gateway and DHCP server<o:p></o:p><BR><SPAN
style="mso-spacerun: yes">�������� </SPAN>3. my Angelia
board<o:p></o:p><BR><SPAN style="mso-spacerun: yes">��������
</SPAN>4. Ethernet switch<BR>�������� 5. Various other devices
(computers, VoIP phones, etc)<o:p></o:p><BR><o:p></o:p><BR>If I connect
everything in the shack via an old Netgear FS116 unmanaged 10/100Mbps switch
then everything works fine - the Angelia performs Ethernet link negotiation and
comes up, sends DHCP request, gets reply, sets up IP address, etc.<SPAN
style="mso-spacerun: yes"> after which </SPAN>running up CuSDR on the PC works
when I hit 'Start' it performs auto-detect, finds the Angelia and comes
up...<o:p></o:p><BR><BR>However this network set-up isn't practical for a range
of reasons...�� I have a rack of servers in the garage and that's also where
the internet comes in.�� I have have a machine (called "gate") that provides
network services, firewall, NAT, NTP, DHCP etc. in the garage.<BR><BR>I have my
main PC, the wife's PC, network printers, VoIP phones, etc. in the
study/shack.�� At both ends there's a Netgeat GSM724T 24-port switch and a
Gigabit fibre trunk runs between the switches.<BR><BR>If I plug the Angelia and
my shack PC in to two ports of the switch in the shack and watch the DHCP server
on gate with "dhcpdump" then I see my PC perform DHCP request, get a reply and
come up as expected but when I turn the Angelia on I see nothing?�� What
gives?<SPAN style="mso-spacerun: yes">�� </SPAN>Is the Ethernet
implementation in Hermes and Angelia 'fragile' or incomplete?<SPAN
style="mso-spacerun: yes">�� </SPAN>Is there a problem with link partner
attributes? or timing when talking to managed switches<SPAN
style="mso-spacerun: yes">?�� </SPAN>Does Hermes/Angelia assume that the
link comes up very quickly and transmit DHCP request(s) too soon or without
retries?<o:p></o:p><o:p></o:p><BR><BR>Is there something that can be done about
this?<SPAN style="mso-spacerun: yes"><BR><BR>I really want to be able to use the
Angelia from one or other of two locations in the house on the same local
(switched) Ethernet.<BR></SPAN><o:p><BR>I'm happy to spend some time collecting
diagnostics/debug if this would help.<BR><BR><BR>Regards<BR><BR><BR>Mike
