Some device stop to ping my Mikrotik

RouterOS General
1

Hi Guys,

I have 1 mikrotik as Main Router that control the network 10.250.0.1 on a Bridge and in the other end I have client’s site. They connect using wifi to the AP that is on Port 1 on Main Router and this port is part of the Bridge.

All the configuration work well with about 6 site, all connecting to the Gateway 10.250.0.1.

The problem is that some device like another Antenna, or another Mikrotik stop pinging the Main Router and I receive “request timed out” from that device.

I temporary fix the problem going into the antenna using SSH and in the antenna use SSH again for the sleep device and enter on it. When I’m in the device, I realize a ping to 10.250.0.1 and the the Device awake again from the point of view of my Main Router to the external device.

Can Anyone help?
Thanks

You are not pinging from, nor are you or SSH’ing into an “antenna”. Start by telling us exactly what devices you are pinging from and to. Do not use the word “antenna” to describe any of your devices.

OK, here is the setup:

1 Mikrotik RB450G (MAIN ROUTER 10.250.0.1)
On port #1 and port #2 I have Ubiquiti NanoStation Antennas as Access Point ( so I bridge ports 1 and 2 on Mikrotik)
The antennas are on the same networks like 10.250.0.101 and 10.250.0.102

In other places far from the MainRouter are anothers NanoStation configured as bridge and Stations that connect to the Access Point.
This Antennas also have mikrotik for connect anothers Access Points (ubiquiti) of the same network. And so on…

But the problem is that I can monitor the network using Solarwind Orion Network and sometimes I can see that a Mikrotik or a antenna is not pinging the Orion Request. But the problem is not Orion, because I cant ping to the antenna on my computer.

The antenna or mikrotik is up but they appear to sleep on pinging.

All I can do for fix temporary is going into a near device like another antenna on the mikrotik by SSH. And then I enter to the affected antenna using SSH too. And make this command: ping 10.250.0.1

After that I can ping the antenna. And Orion can see it.

It like the device refuse the ping, but is not ubiquiti or is not mikrotik because this is cause by any.

What do you recommend?

Hello!!

Again, you are NOT pinging antennas… you probably need to hire a professional in your area to look at your setup on-site.

pls post the network diagram with ip address used

Sorry for the long delay, I attached a Network map of the network isp.
I appreciate any help for anyone.

May have to do with bridge vs arp timeout.

When pings fail, try clearing arp table (ip->arp) and try again.
Also check the bridge mac table of every equipment.

first drop the bridge at the main router.use a FE(fast ethernet unmanged) switch,to which connect NAP1,NAP2 and PTP01.Connect the FE switch to either port1 or port2 of the router.Use Ap(WDS) and Station(wds) configuration for the PTP01 and PTP02 link.Also do the same config for the other 3 PTP links as well, that is AP(wds) and Station(wds).this should sort out your issues.
