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
