Help! Ping to lan port OmniTIK U-5H sloooow

3draven · October 6, 2012, 3:47pm

Everything was working one day.
But now:

Ping is ten seconds for LAN network (laptop connected to OmniTIK U-5nd the LAN2 port or PoE LAN1…i try all ports and cables)
Log in to the configuration is possible, but very rare
LAN connection to almost none, even DHCP started working only sometimes
Router self reboots.

Suspect burned ports. I may be that something was wrong or did not understand?

Try a /system reset. And see if something is different.

Also, upgrade to 5.20 and /system routerboard upgrade

This sounds a lot like you got a broadcast storm going on.

Have you made sure you have no layer 2 loops in your network?
Have you check what ammount and type of traffic is traveling around the network?

Is only this routerboard experiencing this problem?

In this state, two access points.
Different cables, different power, but a state one.
Maybe the fact that I added eth1 to standard bridge-local?
In the bridge-local includes: wlan1 eth1 eth2
But I have already reset the settings to default.
They can remain? This could be the reason?

Since you say that 2 APs experience this problem, you need to look at the network first, not the devices.

Please show us a diagram of your topology. This really sounds like a L2 loop somewhere in the network.

Topology…hmmm
notebook->Omnitik1-< >-Omnitik2->ISP (internet)
This AP needed for “radiocable” bridge only. Its all topology
But. If i connect Omnitik->cable->notebook this simultaneously not work.
This AP working fine one day, then i add eth1 to bridge-local and AP is down.
Hard reset it to facory defaults not help my.
Please help.
