asterisk users - Nov 2004 - OT: Grandstream problems

I know this is off topic a little, but I thought I would ask the people
that use this stuff everyday instead of trying to talk to some tech
support guy.

I just got a Grandstream 100 yesterday.  I plugged it into my network
and after a few seconds it showed the correct time and date.  After that
I tried to access the built-in web server.  After several tries I
finally got the login screen.  That took about 10 tries before it
displayed anything.  Then I entered the default password 'admin' and
clicked the Login button.  After that I got nothing.  The phone still
seemed to be working - I could press the Menu button and the menu would
come up and I could scroll through it.

After trying that for awhile, I decided to try a firmware upgrade.  So I
entered the grandstream tftp server address into the phone
(168.75.215.189) and it did seem to do the upgrade.  At least I think it
did.  The "P" entry in the revision screen shows 1.0.5.16.  There are
lots of other revision numbers in there that I'm not sure about.

I also tried changing out the ethernet cable, and plugging it into
different ports on my Linksys switch (BEFSX41), but nothing works.

Do I just have a bad unit?

TIA

I should add that it was a Grandstream Budgetone 101.  Also, I can ping
the phone, but I get about 10% ping failures.

Be carefull with assuptions regarding the Linksys. There were several
different models (versions) of that hardware, and the early models
did not support 100 meg ethernet worth a darn. Some packets make
it through and a large number did not. Change the port speed on
your phone to 10 meg (if you can) and try again. (I seen your post
on the ping packet loss and that sort of reminded me of problems
seen before.)

My next test would be to plug something else into the socket and see if
I still get 10% ping failures.

Just a quick not on buggy Grandstream behavior- I've experienced some of
the same symptoms described with weird ping responses and the like and
it was a DHCP lease issue.  I'm using Webmin, and ISC DHCP server so
it's easy to see what's going on.  I found that if I powered down the
phone and deleted the active lease, then went into the inactive leases
and deleted all of them as well, then powered up the phone again it
worked perfectly.  

Also if you have any Win95 or 98 machines on your network there may be a
bunch of inactive leases for unused IP addresses, but the darn machines
still respond on the old IP's when you ping them.  Shut down any of
these machines on your network, clear out the leases, and try again.
