6700 losing IP LAN connection requiring reset

Dick Illman

3 times in the last 3 days my 6700 has lost its IP LAN connection and  been unreachable for a connection. I have had to restart the radio with a long shutdown. Using V1.10.16.91 SW with radio and PC connected to a gigabit switch. Using DHCP from a WiFi router. No other devices on the LAN are having a problem.

Hi ****

Some of the Alpha team have experienced this same type of failure occasionally.  It 'seems' that it is related to Gigabit switches when it happens.  Flex is still working on isolating this and a possible solution.

Is there any chance you might have a 100mb/s switch you can try, just as a test?

(I haven't had the problem, but all my switches are 100mb/s)

**** - Did you work for Motorola (a few years ago)?  If so I just want to say hello, but I too also have a 6700 that had a network problem.  The solution was to chuck the PC that I was using.

If you have CLI or GUI access try changing your port speed to 100mb full duplex.

Dick Illman

Yes I worked for the big M from 1974 to 2014. I have a 100 Mb switch to try.. I completely rebuilt the PC a month ago and it has been ok until the last couple of days.

I do not think I have access to the switch but I have a 100 mb switch to try.

I experienced the same symptoms as the original poster.  I ran all of the 1.10.x Beta releases with no problem.  1.10.16 Production was installed the day it was released, and it ran fine until yesterday.  Once the problem started, I was unable to maintain a stable connection to the radio.  I reverted back to 1.9.13, and now all is well once again.

My radio just disconnected. It wasn't the first time but enough times to realize it isn't just a glitch.

A dialog popped up saying I lost connection to the radio. I had to hold the radio power button to get it to reboot but after reboot it connected up. It has happened a couple of times but this is the first time it happened when I wasn't really using the radio.

I'm directly connected from radio to computer. I never have any indication of poor network quality as measured by the radio. Things are generally pretty stable.

Looking in Windows 10 Programs and Features I notice that Intel Network Connections Drivers were updated on 2017-03-07 to version 20.4. This is a Dell system. I'm not sure whether the update came from Dell or from Microsoft. I suspect it's Dell's auto update.

Intel Rapid Storage Technology also updated on the same day.

I checked Event Viewer and note that Intel Ethernet Connection (2) I219-V Network link is disconnected. This event was recorded minutes ago. There are identical events recorded averaging about two per day but not at the same time each day. The first of these events occurred on 1/7/2017. The details of each event are identical: 

Intel(R) Ethernet Connection (2) I219-V 0000040002003000000000001B0004A00000000000000000000000000000000000000000000000001B0004A0

(I'm sure that's meaningful!)

Ethernet Connection (2) specifically refers to the radio's connection. There is no other Ethernet connection made to this computer.

For fun, I right-clicked the adapter to run diagnostics. No trouble was found but the radio disconnected. That's probably to be expected but unlike the reason for this post the radio did not need a reboot.

Hope something here helps with the diagnosis.

Is that a 1G connection?

Kevin

Yes. It is. Always has been set to 1G. I'll set it to 100 Mbps Full Duplex for a while to see if that helps.

Is this an issue that FRS acknowledges and will correct?

I decided to give 1.10.16 another chance.  I did a full uninstall (as I always do), and then I re-deployed 1.10.16.  So far, so good...hope it stays that way.

Thanks for the issue reports.  This behavior is in our bug tracker as issue #4534 and is currently under investigation.

Just lost connection again.

On the Ethernet jack on the radio I see the amber light solid and the green light flashing. Similar on the computer. This is a direct connection - computer to radio.

Recycle the radio and it shows back up in the chooser.

Windows Event Viewer shows:

The network interface "Intel(R) Ethernet Connection (2) I219-V" has begun resetting.  There will be a momentary disruption in network connectivity while the hardware resets.Reason: The network driver requested that it be reset.
This network interface has reset 2 time(s) since it was last initialized.

Not sure if this is helpful:

Kevin, that really doesn't shed much insight into root cause.  Can you open a HelpDesk ticket on your disconnects?  I'd like to work with you one-on-one to see if we might be able to glean some useful clues as to what might be happening.  If Dudley picks up the ticket before I do, please instruct him to assign the ticket to me.  Thanks.
