That is true, but I don’t think so
in this case. I still think it is a
conflict.
95% of the time, when I am batting my head
against the wall over a problem and achieving nothing other than developing a
heck of a headache, I am making the problem more complicated than what it is. The other 5% of the time, I have hosed
things so bad assuming the problem is complicated, that the simplest thing to
do is reset to factory defaults and start over. J
Substitution is a basic troubleshooting
technique that can eliminate or condemn components very quickly.
Substituting the Laptop and having it work
cleared the radio. Swapping IPs
cleared both computers. OK, where
are we at. The machines are OK, the
radio is OK. What didn’t work
when swapped around? The IP of the
PC didn’t. It barfed in both
computers. He could not surf when
that IP was active on the machine he was trying to surf with.
Since the most common
reason for an IP to barf that I have run across is an IP conflict or duplicate
IPs, that is the logical place for me to start and is where I would look first.
I could, of course be wrong. I have been wrong before and will undoubtedly
be wrong again. The most notable
time I was wrong was a few years back when I was certain that I had made a
mistake, but on further examination I discovered that I had not. J

Don’t forget the ARP table issues. If you hook your laptop up on
the client side of an aB after your client was already hooked up…you must
power cycle the aB. This will wipe out the ARP table.
Otherwise the aB gets confused as to who has the IP (which MAC address).

Lockups & Powershot question
Come on,
everyone. Re-read his original message. It’s something to do
with the IP assigned to the PC. He stated that the laptop that would pass
traffic originally would not pass traffic when the IP was changed to that of
the PC. This sounds like an IP conflict to me. There are other
things that could cause it, but it isn’t the radio in this case.
The radio works. He proved that by hooking his laptop to it and surfing.
It has to be something to do with that IP address, be it a conflict, incorrect
setting in a router or server or something similar. That IP barfs in two
different machines which clears the machines. Find what’s screwy
about the IP and you have found the problem.
Let’s
all remember to apply the KISS method and not make things more complicated than
they are.

Lockups & Powershot question
How long after setting the equipment
up and leaving it alone does it fail ? Is timing fairly
consistent for the same pc ?
Could it be that during setup the
client pc is set to an appropriate IP address for the network which allows
traffic to pass thro clients AB (is it only ABs and not APs that are
"locking"?). At some stage later (temp loss of network
connection, dhcp lease expiry etc), the clients pc requires a dhcp lease
renewal and cant see the dhcp server ? Client pc (depending on setup)
might then have no IP address set and be unable to talk to anything. The
AB will not pass dhcp to client if dhcp server is not set to respond in
broadcast mode, not unicast, for BootP. AP would not have this prob -
discussed on this forum in some detail a few weeks ago.
If this is so, could it be its not a
sB prob but a dhcp server issue (sB can't reproduce it 'cos they've got a
properly configured dhcp setup) ? For instance, Suse Linux dhcp ootb does
not support BootP and so will not properly support clients on the ethernet side
of a AB without config changes (range dynamic-bootp). I have seen
other "embedded" dhcp servers wich don't default to this too.
Aramiska Satellite Arc doesn't and can't be configured to. Netscreen 5XP
firewall does and works well.

I have several brands of routers and
they all are still locking up on the LAN side of the SB units..Bt of course it
cant be the SB stuff ;-)

I have
had issues like this with non SB gear, but it is always the customers
router that is the problem. I have some customers who use linksys routers and
they have to power cycle they linksys once a week sometimes. Linksys
is the only router I have seen issues with. Just another thing to throw into
the mix.

Lockups & Powershot question
What happens to most all my client
radios running 0.01.08 is that the Ethernet locks up and no longer passes
traffic to the client. You can ping the radio if you have it set to a private
IP to manage and if you log into it and look at the statistics you will see
that the counter is moving in one direction only. If this is the case all I
have had to do in the past is manually hit the reboot button in the simple monitor
screen to reboot the radio and it comes up fine and you can then see both
counters moving. Its as if when the radios reboots on its on after the watchdog
timer activates,it does not come back up correct. From what I am hearing form
SB it sounds as though all my clients have a windows issue, but what's funny is
that I don't see this as valid because 90% of all my clients are on routers and
routers don't run windows...
SB please please investigate harder
there has to be an issue and your not seeing it.

I heard
about some ethernet lock up with 1.08.
I have 2
unit running it & it never happen & solve disassociation.
Should I
install 1.08 on all ABridges ????
When it occurs,
do the ethernet light work ??
Can you
ping the device ???
If it
would be on a swich with 2 PC........ Would it be dead on both ???

Colin,
I note
in your message that power cycle of the airBridge does not clear the problem but
the invocation of simpleMonitor does. This leads to conclude that the problem
is not in the firmware/hardware but something to do with the TCP/IP stack
configuration of the customer’s PC. When you invoke simpleMonitor, it
automatically starts the device discovery and then add appropriate routes to be
able to reach it. This should normally be not required but I am sure you know
about the “unpredictability” of the Windows networking stack. It
may be worth looking at the TCP/IP configuration on the customer’s PC to
see if something is causing this problem.
In the
recent weeks we have investigated a few reported issues of “Ethernet
lockup of 1.08 firmware” and did not find any correlation. Hope this
helps.

Lockups & Powershot question
I'm wondering if anyone else is
experiencing problems still with AirBridge units locking up? We had a unit
(which I informed support@ about) which locked up with 1.08 firmware, and I was
wondering if anyone else is using 1.08 firmware and expereinced no problems? We
find - if a 1.08 customer locks up you have to 'truck roll' out to them - the
ethernet side just won't come up. Secondly, what exactly does the PowerShot POE
injector do? Or maybe I should rephrase, does it *only* inject power into the
unit? The reason I ask, is that, tonight we had a truck roll to a 1.08 firmware
customer. The unit responded perfectly from the wireless side, but not from the
ethernet side, a power cycle wouldn't clear it. Went round there, plugged in
the trusty Compaq laptop and as soon as simple monitor started - wallah,
ethernet statistics started incrementing. Problem was, when I disconnected the
laptop, and plugged the cable back into the customers PC - no internet access.
So I pulled out the RJ45 plug that connects to the smartbridge (The cable
carrying power & data) - thus removing all power to the Smartbridge unit -
I left the POE connected tho, and plugged the end POE's black back end into my
laptop - worked perfectly (I use a different public IP to test then the one the
customer was using). I next changed my IP to that of my customers PC -
and nothing - no traffic. I then unplugged the powershot (powering off all
SmartBridge equipment), and replugged it in to My PC - all was perfect. I then
plugged it into the customers PC and it was perfect. So
my question is, what else is the PowerShot doing? or - if
it is a pure injector, any ideas why what happened, happend?
One last thing, please track down
whatever it is causing timeouts on certain airbridge units using 1.08
- 1.07 suffers from dissassocation it seems which is bit of
a pain. Oh and finally, I took the liberty of screencapturing the statistics of
a locked up 1.08 unit (from the wireless side ) - You can find them on www.sigmat.demon.co.uk/smartbridge/.
The ethernet counter does not increment, and aged packets seemed to stick at 4?
