Thanks for letting us know. Hope D-Link will correct this.

Engineers need you to answer the following questions:

Update information. We are building below test topology and checking this issue in our lab now.

Internet --- router )))bridge mode via 5G connection(((DIR-880L ---- Switch --- PCs

(Setup the router DHCP lease time to 60 minutes)


But we can't make sure this issue can be reproduce in my environment,
so in this time, please also help provide below information, if possible.

1.Please ask customer to enable syslog function of DIR-880L and dump the complete log for us.
2.Please provide the screenshot for DHCP server settings of wireless router.
3.When this problem happened, please modify PC's IP address from dynamic to static IP and check this PC can access to wireless router or not.

In my current 880L bridge configuration, there is no Ethernet switch between the 880L and the PCs.  Both clients are directed cabled to the 880L LAN ports (1 & 2).

Questions: Can the syslog function send the log to a connected client?  I'm unfamiliar with how to enable this syslog feature so need some pointers.

Which 880L firmware should I run to get the log?  Choice of 1.08B06 BETA or latest 1.20B01 BETA.

Screenshot for DHCP server settings of the wireless router (Netgear R8000) will need to wait till some time next week.  I currently do not have admin rights nor physical access to that router (it's not in my lab).

After the DHCP failure, should I just change a client IP adresss manually to static IP in the 192.168.0.x range?

BTW, both clients behind the 880L bridge (with 1.08WWb04 firmware) have stayed connected to the internet for another 24 hours.

Is Syslog seen in bridge mode? I don't remember seeing it.

You'll need to download a free syslog capture program from the web. I think syslogwatcher has a free one. Install this on your PC and point the 880L syslog feature to the PCs IP address and have the syslog capture program running. Let it collect everything up to when it fails. Save the log and send to D-Link. I presume you could use with B06 or v1.20 since they both are reproducing this.

IF help is needed let me know I can reproduce this as well. I have access to routers here. It was failing while my current D-Link COVR router.

[scan80269]

The 2 clients behind the 880L bridge running 1.08WWb04 firmware continue to have proper internet connections.  It's been 4+ days and counting.

I'm hesitant to change 880L firmware to 1.20 Beta again just for troubleshooting, as I can't afford too much more down time with these 2 clients.  Also, there seems to be no free version of syslogwatcher, at least not without jumping through some hoops.

All indications point to this issue having surfaced with 1.08B06_BETA firmware, and continuing with 1.20B01_BETA.

Can D-Link support a syslog server?  I can point the 880L bridge to such a server, assuming this can work through the NAT of the Netgear wireless router..

[FurryNutz]

Most syslog captures are done with a local PC. Not sure if it can go over the WAN side...

[GreenBay42]

Our group in Taiwan verified this issue in the 1.08 firmware but with 1.20 they are not having any issues. They are continuing to test.

I will let them know you will not have access to the router.

Do you know what firmware is on the Netgear R8000?  Did they change the lease time from the default setting?

The syslog "server" should be one of the computers connected to the 880.  Go here --> https://eu.dlink.com/uk/en/support/faq/routers/wireless-routers/dir-series/dir-878/how-to-check-system-log-for-router and scroll to Method 2. This is for a router but the setup should be similar.

Unfortunately most "free" syslog servers require registration which is annoying.

[FurryNutz]

I think I still have the one sent to me by someone from the forums a few years ago. I'll have a look and see if I still have it.

[scan80269]

The Netgear R8000 router is running firmware V1.0.2.44_1.0.96.

I now have access to the admin page of this router.  The LAN side DHCP server feature does not have a setting for the IP address lease time.  It does however support address reservation, and there are currently none.  This is a consumer grade router.

The 2 clients behind the 880L bridge are still working fine, and it's been nearly a week now.  The multiple clients behind the two 868L bridges are also OK.

[FurryNutz]

If help is needed here I can help collect syslogs if needed. Though my 880L is running AP mode for my NESTs that won't connect to some substandard MESH system I've been forced to use. 

[GreenBay42]

I just got DIR-880 BETA firmware to try scan.

Though my 880L is running AP mode for my NESTs that won't connect to some substandard MESH system I've been forced to use.

LMAO

Thanks, GreenBay42!

My 880L bridge is currently running 1.08WWB04 firmware, and so far neither client has suffered a disconnect from internet.   

Can I just flash this new BETA 1.02 firmware without going through a middle firmware first?

Alos, if I enable syslogging on one of the connected clients, if that client loses ifs IP address lease, the logging would stop, right?  Or do I need to set up the syslogging client with a static IP?  Thanks.

[FurryNutz]

The middle has to be applied first then the v1.20 version...I'll load this up on mine since the 880L I have is now free for other use. 

[scan80269]

OK, I got this latest 1.20 firmware installed into my DIR-880L bridge, one client on static IP running Kiwi Syslog service, and the 880L logging enabled to this client.  No messages logged from the DIR-880L bridge so far.

The other client on DHCP lease has a 24-hour IP address lease as of a few minutes ago.  Will monitor this client closely.   

[FurryNutz]

Ok, mines loaded too. Though not capturing any syslogs. 1 Windows PC and 1 Mac Mini wired to the back of the 880L.
