Re: ROS 6.38 serious DHCP server problem

And again the same problem with 6.39.
What do you mean with "the same problem" as people are discussing different problems here...
DHCP server does not work unless you disable STP.

Re: ROS 6.38 serious DHCP server problem

Just had this issue appear out of nowhere on 6.38.5.
It was working fine but suddenly it stopped issuing DHCP addresses to clients connected through my WiFi AP.
Disabling STP fixes the issue.

Re: RB433UAH not bootig after upgrade to latest firmware (6.37.5)

I managed to get the router working. It was a hardware failure after all. I contacted support and was told that the router is out of warranty. Looking at the board I noticed that 5 of the capacitors were swollen at the top (the router is old after all). http://i.imgur.com/FF5fgCy.jpg So I decided to...

Re: RB433UAH not bootig after upgrade to latest firmware (6.37.5)

I upgraded the firmware very recently so it's probably the latest one.
Is this perhaps it: RouterBOOT booter 3.24 ?

Re: RB433UAH not bootig after upgrade to latest firmware (6.37.5)

Tried with several different power supplies. It was the same. On several occasions it would almost finish installing the firmware but it would reboot before finishing.
Are older versions smaller? Perhaps it might succeed with a smaller firmware?

Re: RB433UAH not bootig after upgrade to latest firmware (6.37.5)

Hi,
I tried on two different computers. Laptop and desktop.
Run as administrator. Firewall disabled.
Boot server enabled.
Nothing happens. I boot the router while holding a metal on the reset "button". Also tried without this but nothing happens as well.

RB433UAH not bootig after upgrade to latest firmware (6.37.5)

I tried upgrading my RB433UAH with the latest available firmware. I think it's 6.37.5. After the upgrade the router was rebooted but now it does not boot. It only beeps once. There is no second beep. Tried resetting it to defaults. The beep is now like a prolonged beep (crackling sound) but there is...

I came here for a solution and got a really bad surprise. Mikrotik does not support UDP and compression! Everyone keeps sa...

Re: IPSEC - one way SPI SA not installed

I'm getting the same problem when trying to connect the Mikrotik to a pfSense firewall.
On the side of the Cisco and pfSense there are no errors displayed.
The only problem I see is that the SA is not installed on the Mikrotik.

Regards.
