Re: RB750UP - Issue

Bravo for 5.20, it seems to work pretty good. Ubiquiti equipment has peaks of about 700mA according to current monitor.

PPPoE Radius CallerID format change request

Hello, Is it possible to strip the ":" in the callerid field for radius request when using pppoe? Reason is simple, in the utmp file there are just 15 chars reserved for callerid, and the last 2 chars of the mac address doesn´t enter in the field. Example: [root@radius]# /usr/local/bin/radwho -rcs 7...

Re: v5rc7 released

Please, wait until MT confirms bugs before jumping to conclusions about bugs, and this is not a bug - this is typical situation when 2 devices can't get auto-negotiation right - it happens now and then with all kind of devices, you need to check your cable, put a switch in between these 2 devices o...

Re: v5rc7 released

Normis,

I was talking about this problem:
http://forum.mikrotik.com/viewtopic.php?f=1&t=47415
Switch is not related, no one of my 750 is running in any switchport configuration and flapping is still present.

Re: v5rc7 released

Note 1: This is a fix-only release, all that was reported in the v5rc6 topic has been addressed. User Manager has not been changed. It seems that no one had noticed the ethernet problem because it was on another topic, so i´m posting the message in this topic to see if it can be solved in 5.0rc8 if...

It was working fine until a few days ago, when i stopped receiving traffic from the bullets and in ip neighbours, i can see rb750-ether1 advertising ...

Re: Ethernet problems caused probably by RFI/EMI

Can´t use fiber because i´m using PoE for the devices connected to the routerboard. There is already a metal box. In fact, the ethernet cables are going inside a metal pipe grounded.

Ethernet problems caused probably by RFI/EMI

Hello, I have a wisp node in a tower used by a 10kW FM transmisor. The node is composed by a metal box, a routerboard 493 (have tried RB150&RB750) and some ubiquiti hardware (1 NS5, 2 B5, 1 R5M) and it is located about half meter away from the upper dipole of the FM radio (i´m unable to put it highe...
