Re: capacitor problem

There are two main parameters for CAP. First is ESR (equivalent serial resistance at defined frequency - lower is better), the secon is ripple current (higher is better, generally ripple current increase with capacity). If its possible to choose 105°C or 125°C design, choose them. The life time will...

Re: RB-493G ethernet lockups

May be basic idea, but did you try to change UTP cable for sure? I have seen twice that one component works fine, UTP was checked by simple tester like this . And another component didn't work well till I changed UTP for new or use second pair for data. For sure use check link using another UTP min ...

I can see the already same for 5.11 using on my 493G. When I added new user trough winb...

Re: RouterBoard USB port not active?

Let me know please the type of HUB, recently I tried connect some USH hub and Flash together with APC and it didn't work (even separately). This was USB hub type like this http://t2.gstatic.com/images?q=...

Re: RB433AH not always starting

What voltage do you use from power source? My experience is that less than 18V can by problematic in case short UTP is used. For sure I use 24V/2A for these boards and good quality POE (sometimes was problem in JACK on POE board and I must cut the wire from power source and solder it directly to the...

I have public IP on WLAN RB1 (for example IP 1.1.1.1). It is possible to redirect packet (only one port) incoming from the internet on ...
